Have we underestimated the eco-anxiety middle-aged and older people feel? According to a recent survey, younger folks aren’t the only ones frowning at the horizon. Eoin Redahan writes.

When you think of a middle-aged person suffering from exo-anxiety, what do you imagine? Is it a grey-haired woman gazing from a mountain peak with a single, heroic tear staining her cheek? Is it an auld fella rending his garments and shaking his fist at the sun?

I mean, possibly, but the reality is probably less dramatic. It could be the Pakistani householder who wonders if her family home will be swept away in the next flood. It might be the 39-year-old Australian who wonders if his country will be habitable when his young child grows up.

It might be the Maldivian who wonders if his homeland will go the way of Atlantis within 20 years. It was me when someone decided it would be a good idea to have a barbecue in the fields beside my house in the middle of the heatwave – when the grass was as dry as straw and wildfires scorched in south London.

The presumption by many is that it’s only the young who feel anxious about climate change, for it is they who will inherit the mess. However, according to recent ONS statistics, the middle-aged and the old are almost as worry-weary as young people.

Having analysed a recent ONS Opinions and Lifestyle Survey, straw specialist firm Drinking Straw filtered some of the stats. They reveal that 62% of UK people over the age of 16 worry that rising temperatures will directly affect them by 2030. Of these, 70% of 16-29 year olds were worried about the heat, but 59% of 50-69 year olds were also worried, as were 57% of those aged 70 and over.

In other areas, the differences were even less stark. When it came to anxiety over extreme weather events, 48% of all adults were worried – only slightly less than the 49% of 16 to 29 year olds who did so.

>> How can I make my garden more sustainable? Professor Geoff Dixon shows us how.

Similarly, regarding water supply shortages, 40% of all adults are concerned about them overall, compared to 43% of those aged 16 to 29. Admittedly, young people are more worried than older adults about rising sea levels (45% vs. 31%), but the differences are noticeably narrow in most metrics.

Surprisingly, it turns out the percentage of those who don’t care at all about the merciless heat, parched land, rising sea levels, and freak weather events is fairly consistent across all segments, with the 12% of 16-29 year olds not giving a fig similar to the 14% of indifferent adults.

ONS figures reveal that most people have made climate-friendly changes to their day-to-day lives, whether they grew up in the age of renewables or the age of coal.

Action stations?

Broadly speaking, UK adults are becoming more eco-conscious, if data from the ONS’ Climate change insights, families and households, UK: August 2022 survey are to be believed. The survey has found that 77% of adults have made some, or a lot of changes, to their lifestyles to tackle climate change.

When the remaining 23% were asked why they made no change to their lifestyles, the most common reason given was: the belief that large polluters should make changes before individuals, followed closely by those who felt that individual change wouldn’t make much of a difference.

It’s clear to most of us that the government must help drive change, including on our roads. Despite the UK’s lagging electric vehicle infrastructure, the study revealed that the number of licensed zero emission vehicles, ultra-low emission vehicles, and plug-in vehicles increased by 71% or more last year.

If people knew there were sufficient charging points dotted around their areas – and if they were further incentivised to give up their gas-guzzling vehicles – those numbers would surely increase.

As bleak as the situation is, it is heartening to see our attitudes changing. Now, if you’ll excuse me, I’ve just read a climate-related story that brought a tear to my eye. If anyone wants me, I’ll be weeping in a dark room (passive-cooled, mercifully).

Paulina Quintanilla has developed a clever way to maximise the froth flotation technology used to extract more valuable minerals from rocks. The SCI Scholar and Poster Competition winner chatted to us about her process and how it could make mineral processing more efficient.

How would you describe your froth flotation technology in simple terms?

Froth flotation is the most widely used technology to separate valuable mineral particles from waste rock. The process is carried out in stirred tanks in which chemical reagents and air are added. Some of these reagents, called collectors, make the valuable mineral particles hydrophobic, which means that they repel water.

Consequently, the valuable mineral particles attach to the air bubbles, covering them and generating bubble-particle aggregates. The bubble-particle aggregates rise to the top of the tank, forming a froth that overflows as a mineral-rich concentrate, while the waste rock leaves from the bottom of the tank as tailings.

Froth flotation is also relevant in several other industrial applications, such as water treatment and paper de-inking.

How would you describe your froth flotation technology in simple terms?

This research focuses on optimising the froth flotation process using a control strategy called model predictive control. To this end, mathematical models were developed to represent the phenomena inside a flotation tank. These models are then used to ‘predict the future’ so that decisions can be taken now (we can control the process) to improve the froth flotation performance.

Model predictive control is a powerful optimisation strategy that has been widely used in other processes, including in the petrochemical industry, but it is still very new in the mineral processing industry.

One of the main advantages of this research is that the models are physics-based. This means that they were developed from the fundamental physics of the process rather than from data, which makes them useful under any operating conditions, for any flotation tank size. This is particularly interesting for application in the large flotation tanks used on an industrial scale.

How could this work benefit industry and make processing more efficient?

Building clean technologies for the transition to 100% green energy is creating a massive demand for a range of minerals. For example, copper mines would have to ramp up production considerably to satisfy the extra 7% predicted demand. Meeting that demand, however, is becoming more and more challenging as ores are becoming lower grade, deeper, and more complex.

This implies that there is an urgent need to optimise current processes to extract the necessary minerals and metals more sustainably and efficiently. As froth flotation is a large-scale process, even small improvements in the separation efficiency would translate into important increments in production.

We demonstrated that improvements of between 8 to 22% in metal recovery were achieved by implementing a model predictive control strategy at the laboratory scale, revealing an untapped potential for implementation at an industrial scale. This research could serve as a promising next step for the mining industry to meet future metal and mineral demands by extracting more metal for the same amount of resources, such as water, energy, and chemicals.

Your flotation tanks are actually based in Chile. How do you operate them remotely?

I am currently implementing an online model predictive control strategy in a laboratory-scale flotation bank in Chile. I monitor and control this experimental rig from home, in the UK.

The experimental rig was automated in such a way that all the instruments (e.g. air flow meters, controllers, pumps, etc.) are connected to a module called ‘Programmable Logic Controller’. This module is then connected to a workstation computer, which I access from my laptop in the UK.

The Programmable Logic Controller allows me to obtain measurements in real-time and control the system. In this case, the measurements are used to update the mathematical models, while the system is controlled by changing the ‘revolutions per minute’ of the pumps (to change the pulp levels) and/or moving the air valves (to change the airflow rates).

Could this process be used to extract other materials? If so, which ones?

While froth flotation is widely used to separate sulphide minerals of copper, it is also used to separate other sulphides, such as those containing lead, zinc, and molybdenum.

You won an SCI Scholarship. How did you use the funds you received to develop your research?

I used the generous SCI scholarship to partially fund a two-month visit to the laboratory in Chile. I set up new connections for remote control by installing new instrumentation to make it even more automated, and I carried out preliminary online control experiments. Since then, all the control experiments have been carried out from my laptop at home.

I also used the scholarship to fund my participation in several conferences, including one in person in Athens, Greece, in 2021. I have participated in Scholar Days in 2020 and 2021, in which I presented advances in my PhD research to a wide audience. This year, I presented my PhD research results at SCI headquarters for the first time and participated in the Poster Showcase, where I won first place.

What are your future plans for this innovative technology (and other potential research)?

I plan to keep up the momentum of researching froth flotation optimisation, as I believe that there is still a long way to go for improvement, particularly at an industrial scale. Model predictive control has not been widely explored within the mineral processing industry despite the fact that it has shown great potential. There is still a gap between academia and industry that should be bridged, sooner rather than later, to improve the performance of the process.

Apart from the model predictive control strategy using physics-based models (including the one I have investigated during my PhD research), many other control strategies show great potential to be tested and implemented at an industrial scale.

This is particularly applicable in mineral processing plants, as most of them collect a huge amount of data that could serve as valuable inputs for further improvement and optimisation, using novel engineering tools such as artificial intelligence and digital twins.

Paulina is part of the Advanced Mineral Processing Research Group at Imperial College London, whose research includes fluid dynamics of flotation tanks and multi-criteria decision-making for sustainable mining and mineral processing.

What is the verdict on the 100% sustainable fuel Formula 1 plans to use in its cars, and is the new E10 fuel this season doing any good? We asked David Bott, SCI’s Head of Innovation.

Beware of Greeks bearing gifts. This phrase comes from Virgil’s Aeneid, and it refers to the Greeks’ gift of a giant wooden horse to their enemies during the Trojan War. But this was no gift at all.

This warrior-filled, hollow wooden horse that the Trojans wheeled inside the gates of Troy was a ploy from the Greeks to get inside the city’s impenetrable city walls and ambush their enemy. It turned out things weren’t quite what they seemed.

Just as Trojans became wary of giant wooden horses, we should be wary of Net-Zero pledges. These promises seem impressive but, if you look inside, they might not be quite as beneficial to the environment as advertised – at worst, they could be hollow.

Whenever an organisation talks of carbon credits, makes a vague reference to biomass or a grand pledge with little detail, it is worth closer investigation.

Formula 1 recently made a sustainability pledge of its own. Following its decision to use E10 fuel in the cars this season (a mixture of 90% fossil fuel and 10% ethanol), it has announced plans to use a 100% sustainable drop-in fuel in its vehicles as part of its plans to reach Net-Zero by 2030.

On first reading, the terms Net-Zero and Formula 1 don’t sit easily together. Isn’t this the sport where 20 cars can burn more than 100kg of fuel each per race? The same travelling circus in which cars, teams, and drivers are flown and ferried all over the world for more than eight months of racing?

By its own calculation, in a November 2019 report, Formula 1 is responsible for 256,551 tonnes of carbon dioxide emissions each year. To put that figure into perspective, you would need to drive for 6,000km in a diesel car to generate a single tonne of carbon emissions – multiply that by 256,000, and Net-Zero feels some distance away.

What about the E10 and proposed drop-in fuels?

Both Formula 1’s new fuel and pledges merit closer inspection. Regarding the move to the E10 fuel in Formula 1 cars, David Bott, SCI’s Head of Innovation, wasn’t exactly gushing.

‘E10 is an evolutionary backwater – adding just 10% ethanol does nothing for emissions,’ he said. ‘A quick enthalpy calculation shows the energy in the fuel has decreased, so you need more.’

The proposed move to a ‘100% sustainable drop-in fuel’ used in standard internal combustion engines is seen by many as a positive move. Formula 1 says the fuel will be made using components from either carbon capture, municipal waste, or non-food biomass.

Each of these ‘components’ on its own is worth exploration. For example, what types of municipal waste do they mean, which types of non-food biomass are they talking about, and what about the manufacturing process?

Biomass fuel is controversial due to concerns over carbon sequestration and land use.

The passage of time will reveal more but, again, David has questioned the green credentials of the proposed fuel. He said: ‘What Formula 1 is proposing to do is analogous to sustainable aviation fuel – to make octane from a non-fossil source of carbon.’

‘[To do this], you can use biomass or “synthetic”, which basically means distillate plastic waste. It is effectively using fossil carbon that was used for something else; so, it doesn't make the situation any worse, but neither does it really contribute to lowering emissions. It’s just short-cycle carbon.’

Freight with difficulty

The mention of aviation is pertinent when it comes to Formula 1. The emissions generated by the 10 teams’ vehicles across 21 Grands Prix, including races and testing, account for just 0.7% of Formula 1’s total emissions. But by far the biggest contributor to its CO2 emissions are logistics – the movement of equipment from venue to venue by land, sea, and air.

The equipment used in Formula One must be transported from continent to continent by sea, land, or air.

After that comes business travel at 27.7%, which includes the air and ground transportation of all individuals, as well as the hotel footprint from all Formula 1 teams’ employees and major event staff. So, it’s clear that the main environmental problem isn’t the fuel used during the races; it is all of the other transport emissions.

To be fair to Formula 1, the sport has made an effort to make operations greener, including powering its offices using 100% renewable energy and taking measures to make freight more efficient.

However, any claims that it is motoring to Net-Zero by 2030 need to be chased with a liberal swig of scepticism. A Net-Zero 2030 goal provides a nice headline, but how you get there is the story.

Fossil fuels don’t just keep our motors running. They don’t just heat our homes. They form the basis of many of our everyday products.

Problem is, fossil carbon is cheap and reliable. Nevertheless, bit by bit, many companies are weaning themselves off petrochemical feedstocks.

For Unilever, that means dishwasher liquids with cleaning agents made from fermented sugar. For Croda, it means using corn to create a bio-ethylene oxide that can replace some surfactants in its personal care products.

So, what other moves have organisations made lately to create greener feedstocks?

1. Castor seed building blocks

Arkema is using castor seed in a huge range of products.

Arkema has received certification for its castor seed-based materials in products that include cosmetics, fragrances, lubricants, and pharmaceuticals.

The Paris-based speciality materials company says it will use castor seed for 100% of its monomer, polymer, and oleochemical production in its plant in Singapore.

Part of the problem with developing green feedstocks is making them financially viable and resilient. Growing these feedstocks sustainably is also important. For example, palm oil contains many products that make it a useful feedstock for those in the chemicals industry, but the way it is farmed, and its effect on the soil, are routinely criticised.

To that end, Arkema says that 13,300 hectares used to grow its crops (primarily in Western India) are sustainably farmed under the Sustainable Castor Caring for Environmental and Social Standards code.

2. Nutrient recovery

Unused nutrients from agriculture could be turned into biofertiliser.

The US Environmental Protection Agency (US EPA) is taking part in a project with Northwest Florida Water Management District and May Nursery that will demonstrate nutrient recovery technology.

According to the US EPA, the aforementioned parties will demonstrate how unused nutrients from agriculture can be captured and turned into a biofertiliser that will help farmers along the way to more circular agricultural processes.

>> How do we make a large-scale move to greener feedstocks? Several of SCI’s Corporate Partners weighed in on the issue.

3. An alternative to plastic wrapping

Thyme oil’s antimicrobial properties could help extend the shelf life of fresh food.

Researchers at Rutgers and Harvard have created a plant-based spray coating for fresh food packaging, which they believe could reduce our reliance on petroleum-based packaging.

The researchers liken their technology to the webs that shoot from Spider-Man’s wrist. Their stringy material is spun from a hair-dryer-like heating device that is shrink-wrapped over foods as diverse as avocado and sirloin steak.

Their biopolymer contains natural antimicrobial agents – thyme oil, citric acid and nisin – to fight spoilage. The wrapping can also be easily rinsed off and degrades in the soil within three days.

4. Degraded by the light

North Dakota researchers have developed a plastic that degrades in a wavelength of light not contained in the spectrum of sunlight on earth.

Biodegradation is a prickly issue. Many are sceptical about the way biodegradable plastic bags interact with the natural environment, and others argue that we should focus on upcycling products rather than downcycling them.

That’s partly what makes a new bio-based vanillin plastic so interesting. A team of US researchers from the Center for Photochemical Sciences, Bowling Green State University, and North Dakota State University has created lignin-based polymers that degrade when exposed to light of a specific wavelength – a wavelength not contained in the spectrum of sunlight that reaches the earth.

The result of this, they claim, is that up to 60% of the monomers could be polymerised again with no loss of quality. So, in theory light-triggered degradation could make it much easier to re-use these materials.

Dr Yalinu Poya Gow’s eventful career has taken her from Papua New Guinea and China to Glasgow, with an impressive array of awards collected along the way. She spoke to us about her successes, overcoming challenges, and feeding the world’s growing population through ammonia synthesis.

Dr Yalinu Poya Gow

Tell us about your career path to date.

I was born and raised in Lae, Morobe Province, in Papua New Guinea. I did all my schooling there, then moved to Port Moresby, the capital, to do my university studies. I attended the University of Papua New Guinea and graduated in 2011 with a Bachelor’s Degree in Science, majoring in Chemistry. After graduation, I worked at the Porgera Gold Mine in the pressure oxidation circuit as a Process Technician.

In 2014, I moved to China and did a Master’s in Inorganic Chemistry, majoring in Heterogeneous Catalysis, and received the Outstanding International Student award. In Autumn 2016, I was accepted into the University of Glasgow and began my PhD in Chemistry, majoring in Heterogeneous Catalysis.

I completed my PhD studies December 2019 and graduated in June 2020. My PhD research was on making catalysts suitable for small-scale ammonia production, such as on a farm. Ammonia is a simple compound that is primarily used to make synthetic fertilisers to grow food to feed 40% of the world population; as a result, there is great interest in sustainable ammonia production on a small-scale.

I have received a total of 18 awards and honours in relation to my PhD work, including: the 2020 Commonwealth Chemistry award winner in Green Chemistry; the 2019 Green Talent Award from the German Ministry of Education and Research; and the Plutonium Element Award by International Union of Pure Applied Chemistry (IUPAC) as one of the top 118 chemists in the world under the age of 40; and first place in a Society of Chemical Industry PhD Student Competition.

My research has been highlighted and featured by the American Chemical Society, Scottish Funding Council, Society of Chemical Industry and QS Top Universities. In addition, I have been honoured by the University of Glasgow for my ammonia synthesis research and named 2020 University of Glasgow Future World Changer.

Which aspects of your work motivate you most?

The aspect of my job and research that motivates me the most is contributing to a greater cause. I play a role in contributing towards improving the livelihoods of billions across the world. I am also an educator, teaching students across the world, so in a sense I am developing the world’s human resource: equipping scientists and engineers into bettering themselves and the world. This is my motivation.

Ammonia synthesis research is key in helping us feed the world’s rapidly growing population.

What personal challenges have you faced and how have you overcome them?

The personal challenge that I face is being undervalued. I, as a scientist, am usually overlooked. You see, everyone talks about sustainability, climate change, and what we should do to overcome these challenges, but when it comes to getting the job done, young scientists like me who have a lot to offer are being overlooked by institutions and organisations despite meeting criteria.

The thing with me is that I came the hard way, I worked extremely hard to get where I am and do not sway from paths nor give up easily. I continue to grow in my passion in science and research despite the limited opportunities. I believe all good things come to those who work hard and are patient.

>> We have spoken to many amazing women chemists. Read more about Dr Anita Shukla and the drug delivery systems she is developing.

What is the greatest future challenge for those in your industry and at home, and how could these be addressed through your work?

The greatest challenge is the lack of opportunities. Catalysis is somewhat a niche field when it comes to research fellowships, industrial jobs, or anything in between. Catalysis can help solve some of our problems, but it is often overlooked. Ammonia synthesis is a testament to how catalysis feeds 40% of the world population. When you take into account the UN 2030 Sustainable Development Goals and the world’s growing population, ammonia synthesis should be highly worthy of consideration.

It is the same in where I come from. Papua New Guinea and the Pacific Islands have brilliant and naturally gifted people. The only challenge is the lack of opportunities and services.

Which mentors have helped you along the way and how did they make a difference?

Mentors that have helped me along the way were my parents, who always believed in my potential, instilled in me hard work and discipline, and always reminded me that I have a purpose. I also have had the support of my science teachers at school, undergraduate lecturers and postgraduate supervisors. They are all heroes and heroines of science and have shaped my life greatly!

What is the current state of play within your sector with respect to equality, diversity, and inclusion – and is enough being done to attract and retain diverse talent?

I am a Pacific Islander woman in Chemistry. I am a minority in the world and more so in my field. Opportunities should be given to us as we do not just represent ourselves, we represent an entire people of the Pacific.

That is the whole reason why I wanted to do a PhD in Chemistry with an underlying theme of sustainability, so I can give something back and help my people because they are the ones who face the drastic effects of climate firsthand.

Many people speak of inclusivity on paper, but it needs to come into fruition. Inclusivity is not just a box to tick. There is so much diverse talent out there – brilliant, and qualified people from minority ethnicities.

Is there any advice you would give to young professionals and young people from Papua New Guinea?

Never give up – that is all. Where you come from, your past or present, status in life, background, gender, age, what you look like, these should not hold you back from achieving your goals. Yes, life is hard, but you have a purpose.

Some have it easy, most of us have it hard, but we are tough and resilient people. Eventually, you will reach your goals one day, look back and see that all the hardship faced along the way was totally worth it.

Re-using waste materials and converting them into chemicals will help us create a closed-loop system. Ahead of the SCI Engineering Biology symposium on 23 May, Martin Hayes, Biotechnology Lead at Johnson Matthey, spoke about some exciting approaches and the challenges involved in making the low-carbon transition.

The journey to Net Zero is well underway, with a number of countries already committed to Net Zero by 2050. To achieve this ambitious goal, companies and governments must take a new approach to waste, shifting from linear processing to a circular model.

This involves recycling and reusing products to create a closed-loop system that uses fewer resources and reduces waste, pollution and carbon emissions. As we journey towards Net Zero, these ‘circularity’ principles are increasingly embedded in the research and design of products.

Re-using waste from chemical processes

As a leader in sustainable technologies, Johnson Matthey (JM) is striving to help the chemical industry transition. Martin Hayes, Biotechnology Lead, explains: ‘More and more companies are starting to move away from linear chemical processes to circular ones, which is definitely a step in the right direction.

‘They’re looking at how the waste from chemical processes may be the source for biological processes. Biological entities such as enzymes or organisms can even recover precious metals from waste streams, maximising value while reducing waste.’

>> How are young chemists tackling climate change? Read more in our COP26 review.

In other cases, gas fermentation can upgrade waste products, particularly carbon dioxide and hydrogen, and convert them into chemicals. Hayes explains: ‘In this instance JM joins biology and chemistry to get the desired end product without affecting the customer experience, but making the process much cleaner.’

Fermented food waste could be converted into chemical building blocks.

Food waste is another contributor to greenhouse gas emissions. A circular approach may consider fermenting food waste to convert it into useful chemical building blocks. ‘What is valuable about this is that these chemicals are not produced from virgin fossil material,’ he adds.

Collaboration and feedstock issues

To realise the potential in these technologies and new businesses, it’s important to take a collaborative approach and for multi-disciplinary teams to work together. Hayes continues: ‘We know that getting the biology to the end product requires engineers, chemists, microbiologists, and biochemists – different scientists working together with commercial expertise to make a product that is sustainable, has a low environmental footprint, and is still profitable.

‘We work collaboratively in partnership because we recognise we need to develop these solutions in ways that reflect the needs of each client and the broader society.’

But the scale of the issue shouldn’t be underestimated. On the one hand, those biological entities will require engineering to become efficient catalysts, working selectively with less-than-ideal feedstocks under demanding reaction conditions. On the other hand, scaling up and optimising processes such as fermentation can be resource intensive and involve large volumes.#

This type of catalyst customisation and process intensification calls for a multi-disciplinary team: bioinformaticians, molecular biologists, chemists and chemical engineers working together.

While the UK leads in renewable technologies, it is also important to think in terms of connected systems rather than isolated applications of technology. That broader perspective in a circular system will get us towards Net Zero and is embodied by the SCI’s symposium on Engineering Biology with which JM is proud to be associated as a (fittingly) Platinum sponsor. This is a topic which is entirely consistent with, and supportive of, JM’s vision of a cleaner, healthier world.

>> How do we move to non-fossil fuel feedstocks? Here’s our report on the Parliamentary & Scientific Committee Discussion Meeting on 28 March.

Why do we ignore climate change and what can we do about it? That’s what Toby Park, of The Behavioural Insights Team, explained in our latest SCItalk. Eoin Redahan reports.

Do any of these describe you?

A.I recycle whenever I can, but fly twice a year.
B.I switched to a renewable energy provider, but still drive to work twice a week.
C.I make sure all unnecessary lights are switched off in the house, but eat beef occasionally
D.I plan to live a greener lifestyle, but the real difference will be made at government level.

When it comes to climate change, most of us are full of good intentions. We want to do the right thing but when change becomes too difficult or inconvenient, people (like me) lapse into old habits. In his excellent talk, why we ignore climate change and what we can do about it, Toby Park explained these contradictions and outlined how ‘nudge’ behaviour can be used to tweak our habits.

Fundamentally, Park argued that most people mean well. After surveying a couple of thousand people in the lead-up to COP26, the Behavioural Insights Team found that 67% of respondents planned to take at least five new actions to tackle climate change and 99% said they would take at least one.

So, why then do we ignore climate change en masse? ‘We are like swimmers in a stream,’ Park said. ‘We have the opportunity to swim in one direction or another but we are in a stream that has a current.’

We’re good at recycling but not as resolute when it comes to taking fewer flights.

Life is hard enough. We tend to do what is easy and affordable, but there are other reasons why we’re not falling over each other to buy electric vehicles or driving to the south of Spain for our holidays instead of flying.

The first is psychological distance. For many people, the prospect of climate change is too distant to take seriously. Unless you have woken up to find your kitchen submerged by flooding, its effects may seem far away; yet, the changes we must make are in the present.

The problem is, it’s sometimes hard to act when you cannot feel the urgency. So, people find it hard to frontload the hardship, as they see it. Park likened it to being told that you must have the hangover before you go drinking – and how many of us would choose that?

Second, we are experts at fooling ourselves. As Park noted, we’re all natural storytellers when it comes to crafting positive images of ourselves. We are the masters of cognitive dissonance. On the one hand we feel virtuous when we recycle paper, plastic, and food scraps, yet we’ll hop on a plane for that wedding in Dublin. 

‘We all have the tension of what’s in our own self interest and what’s altruistic or pro-social,’ Park said, adding a Robert Heinlein quote that encapsulates the human condition. ‘Man is not a rational animal,’ he said. Man is a rationalising animal.’

A third reason why we ignore climate change, according to Park, is that our actions rarely benefit us personally. If you buy an electric vehicle, the price of that new Tesla will sting and you’re not going to benefit from the carbon emissions saved. However, if there is collective action, everyone would benefit from cheaper electric vehicles to less filthy air.

So, what can we do about climate change?

Nudge behaviour

As was mentioned above, one of the foci of the Behavioural Insights Team is encouraging ‘nudge’ behaviour – what Park described as softly encouraging a certain type of behaviour without restricting choice. And it turns out, there are lots of ways to nudge us well-intentioned, self-centred creatures into healthier habit.

Examples of nudge behaviour are everywhere. In Switzerland, energy companies made green energy the default choice and people – out of either convenience or conscience – tended to stick with this option. Park mentioned how one canteen reduced food waste by up to 40% through the introduction of a small friction: removing the plastic trays (Thiagarajah and Getty 2013). In a similar sphere, he said Sainsbury’s Cafe increased orders of its plant-based meal options by calling items ‘field-grown’ rather than ‘meat-free’ or ‘plant-based’.

Park mentioned that we can motivate different behaviour by introducing a social element. He noted that solar panels were found to be socially contagious in California and parts of Europe, while the same has happened in the UK with the introduction of green number plates for electric vehicles.  

Comparing people to their peers is another useful way of changing habits for the better.  Benchmarking people’s behaviour against the norm – such as telling someone they use more energy than most customers – is one way of doing it. Publishing environmental performance league tables for organisations is another to encourage a climate-friendly approach.

If you don’t think these sorts of nudge behaviours don’t work, think of the humble plastic bag tax. When you take your own bags for your weekly shop, you might save just 30p on a £30 shop. But have you done it? And are you doing it still?

Unfortunately, there is no dancing around the fact that 60% of emissions reduction requires behaviour change, according to Park. So, nudge behaviour will help but we’ll be needing more power behind that elbow.

What’s in a name? Language can have a profound effect on our choices. Now, who’s for a field-grown breakfast?

‘Small nudges aren’t enough,’ he said. ‘We also need to apply this lens to systemic, transformative change. That means finding smart ways to tilt the functioning of markets.

He said that consistent, long-term decision making is not only important for individuals but for businesses too.

‘Incentives are massively important for corporations,’ he added. ‘That would generally be my first port of call. That’s where the bigger impacts can be found.’

At the end of the talk, a member of the audience asked Park, simply, if there was hope? To answer that, he offered the example of plant-based food.

Not so long ago, many plant-based meat alternatives were the preserve of the few. However, consumer interest in plant-based foods has ‘mushroomed’ in recent years and retailers have responded with a swath of new food products.

‘Change can be runaway and self accelerating, Park said, ‘and we shouldn’t forget that solutions can scale exponentially… New norms can, all of a sudden, spread very quickly.’

For many of us, it’s exciting to see the growth of the electric vehicle industry. Our personal transport will be cleaner. Our roads will be quieter. Indeed, from 2030 the UK government will ban the sale of pure internal combustion engine cars, and the widening role of ultra-low emission zones will hit many motorists in the pocket. Whether we like it or not, change is coming.

That does not mean we are prepared for it. As demand for electric and hybrid vehicles accelerates, and more stringent trade rules put pressure on having a local battery supply chain (stricter Rules of Origin for trade will come into force by 2027), the UK must get its complete supply chain up to speed.

Battery supply chain challenges

For this to happen, chemists, suppliers, manufacturers, innovators, government representatives, and others need to make strides in several areas. Over the past year, a group of more than 50 participants at SCI’s Energising the UK Battery Supply Chain workshops have identified next generation technology, the scale-up of innovative technologies, the skills and knowledge base, and standards for materials testing as areas for improvement.

Brine pools for lithium mining. There is a global clamour for raw materials including lithium.

The UK also needs a consistent stream of key battery materials. It needs technologies that reduce the dependence on some of the current materials for hybrid and electric vehicles. It must integrate efficient battery recycling and manufacturing approaches to reduce its dependence on long-distance imports and much coveted raw materials such as lithium, nickel and cobalt.

It is a big challenge. As David Bott, SCI’s Head of Innovation (who helped run SCI’s five Energising the UK Battery Supply Chain workshops) said, there isn’t enough of a UK electric battery supply chain at the moment.

David did note that the UK Government (through UK Research and Innovation) has been investing in the scale-up of cell assembly through the Energy Innovation Centre at WMG (from 2012/3) and the UK Battery Industrialisation Centre (through UKRI and the Automotive Propulsion Centre). It will also support the construction of Britishvolt’s electric battery ‘gigafactory’ in Blyth, Northumberland.

However, he added that: ‘All of them, however, are talking about the assembly of the cells and 60% of the value is in the materials. We need a battery materials supply chain in the UK – not all the way back to mining, of course, but as much as we can.’

Smoother collaboration is also required. ‘We need recognition that the UK needs more support for the chemistry part of the supply chain,’ he said. ‘We need a lot more collaboration – engineers need to understand that chemistry companies would engage more if they understood the size of the opportunity. The main thing we need at the moment is awareness of the opportunities.’

Promising developments

Despite the difficulties, green shoots have appeared recently. In late January, the government announced that it has backed Britishvolt’s aforementioned plans to build large volumes of electric vehicle batteries (through the Automotive Transformation Fund). According to the government, the factory will produce enough batteries for more than 300,000 vehicles a year and create 3,000 direct, highly-skilled skilled jobs. Britishvolt have also announced a partnership with Glencore to recycle battery materials.

Oxford-based chemical products manufacturer Nexeon has secured US$80 million (about £59 million) in funding to scale up the production of its silicon anode materials. Finally, Sheffield-based sodium-ion battery technology company Faradion has been acquired by Indian conglomerate Reliance Industries for £100 million. A further £25 million will be invested as growth capital to accelerate the commercial rollout of its sodium-ion battery technology.

Faradion says that its sodium-ion technology provides ‘significant advantages compared to lithium-ion technology, including greater sustainability, a patented zero-volt safe transport and storage capability’.

So, there is some good news to celebrate as you gather around with your families to celebrate National Battery Day. The battery supply chain, unfortunately, must wait for another day.

Machine-made snow has made this Winter Olympics happen in Beijing, but at what cost?

If you take a look at the weather in Beijing right now, you’ll notice that it isn’t really that cold. You can enjoy daily highs of about 8°C in early February, which we’d be happy enough here in London.

These mild conditions have been a problem for the organisers of the Winter Olympics, which are currently taking place in Beijing and environs. Indeed, the distinct dearth of snow has meant that the Beijing Games have become the first to be run largely on artificial snow.

Snowmaking machines spray artificial snow on a ski slope during the FIS Ski Cross World Cup, a test event for the 2022 Winter Olympics

For some, the presence of 130 fan-driven snow generators and 300 snow-making guns spewing out machine-made snow represents a waste of resources, even if these machines are powered entirely by renewable energy.

In all, 49 million gallons of water will reportedly be used to make the Games possible. So, to say they are water-intensive is something of an understatement. However, the issues don’t end there. There is also an issue with the type of snow produced.

>> What can you do about climate change? Register for this free talk to find out more.

Some claim artificial snow creates more dangerous conditions for athletes.

According to the recent Slippery Slopes report written by the Sport Ecology Group (in conjunction with Loughborough University UK and Protect Our Winters UK), the composition of artificial snow can create dangerous conditions for the athletes. Basically, it creates a faster, harder surface that could result in more severe injuries.

The reason given for this is that artificial snow is almost 30% ice and 70% air, compared to natural snow, which is closer to 10% ice and 90% air. This ‘grittier ice-pack’ creates tougher conditions for athletes, many of whom travel at great speeds down steep slopes.

In the same report, former Winter Olympian Laura Donaldson explains why these machines create suboptimal snow. ‘The artificial snowflakes they generate have cylindrical structures (unlike the far more intricate structure of natural flakes),’ she said, ‘which mould together to form bulletproof ice conditions.’

Furthermore, this less permeable layer of ice may hinder the growth of vegetation, and the noise of the machines disrupts wildlife. In some resorts, chemicals are also added to create longer lasting snow.

At Beijing, the organisers claim not to have used chemicals in the snow-making process. However, others rely on machines and chemical-kind for a helping hand. According to the Sport Ecology Group report, a pesticide was used at the 2010 Games in Vancouver to allow the water to freeze at higher temperatures; and snow hardeners such as salt and fertiliser have been used to improve snow quality on cross-country skiing trails.

If hosting the Winter Olympics in an area without much snow seems crazy to you, it might not be quite as daft as you think. The bleak reality is that global warming is reducing the number of venues that can host this enormous event without artificial help.

According to an academic paper by Scott et. al. in 2014, only six of the last 19 Winter Olympics host cities will still have the climatic conditions to do so by the 2080s. Of course, that doesn’t take artificial snow into account.

So, when you see Qatar being awarded the 2050 Winter Games, don’t tell me you haven’t been warned.

Johnson Matthey has launched a technology to help create a green hydrogen-based aviation fuel, while the European Commission has approved a €900 million scheme (£750 million approximately) to support renewable hydrogen investments.

SCI Corporate Partner Johnson Matthey has developed HyCOgen to convert CO₂ and green hydrogen into a scalable and sustainable aviation fuel (SAF). The speciality chemicals company says it has combined this Reverse Water Gas Shift technology with FT CANS Fischer Tropsch technology through a catalysed process. With this approach, the green hydrogen and CO₂ are converted into carbon monoxide, which is combined with additional hydrogen to form syngas.

Integration with the FT CANS technology is used to turn 95% of the CO₂ into a high quality synthetic crude oil. This synthetic crude oil can then be upgraded into sustainable, drop-in fuel products for aviation transport – a sector responsible for 12% of transport-related CO₂ emissions, according to the Air Transport Action Group.

Green hydrogen fuel, produced using renewable energy, could help decarbonise the aviation industry.

Jane Toogood, Sector Chief Executive at Johnson Matthey, said: “Given the challenges associated with new propulsion technologies and airport infrastructure, plus the long asset life of aircraft, there are significant hurdles in moving from hydrocarbon-based aviation fuel to alternatives such as battery electric or hydrogen.

“By combining HyCOgen with FT CANS, we can now deliver customers a cost-efficient, reliable and scalable technology to help increase SAF production, backed by our track record of successful technology development and commercialisation.”

€900 million fund for non-EU countries

In other hydrogen-related news, the global hydrogen industry has received a boost with the European Commission approving a €900 million German scheme to support investments in renewable hydrogen production in non-EU countries.

The aim of the H2Global project is to meet the growing EU demand for renewable hydrogen production, which is expected to increase significantly as EU countries reduce their reliance on fossil fuels. Even though the initiative will benefit EU countries, UK-based organisations concerned with hydrogen power could benefit from this investment.

>> Young chemists are getting creative in the fight against climate change. Read more in our COP26 review blog.

Margrethe Vestager, the European Commissioner for Competition who is in charge of competition policy, said: “This €900 million German scheme will support projects leading to substantial reductions in greenhouse emissions, in line with the EU’s environmental and climate objectives set out in the Green Deal.

“It will contribute to addressing the increasing demand for renewable hydrogen in the Union, by supporting the development of this important energy source in areas of the world where it is currently not exploited with a view to importing it and selling it in the EU. The design of the scheme will enable only the most cost effective projects to be supported, reducing costs for taxpayers and minimising possible distortions of competition.”

Greenhouse gas emissions statistics can be misleading. At a recent SCI webinar on the Future of Agriculture, the Agrisciences Committee put its finger on some glaring gaps in the figures.

If all of the cows in the world came together to form a country, that nation state would be the second highest emitter of greenhouse gas emissions in the world.

McKinsey Sustainability’s statistic was certainly startling. However, Agrisciences Group Chair Jeraime Griffith mentioned other equally striking figures in his wrapup of the social media discussion generated at COP26.
In his talk as part of the Agrisciences Committee’s COP26 – What does it mean for the future of agriculture? webinar on 7 December, Griffith also noted that:

1. farming accounts for more than 70% of the freshwater used worldwide, according to the Organisation for Economic Co-operation and Development (OECD)
2. and 31% of human-caused greenhouse gas emissions come from agrifood systems, according to the Food and Agriculture Organisation.

On the face of it, these figures are sobering; yet, like many agriculture-related figures, they don’t tell the full story.

Insane in the methane

Kathryn Knight felt that agriculture received negative press at COP26 in relation to greenhouse gas emissions. ‘It doesn't seem to take into account carbon sequestration (capturing and storing atmospheric carbon dioxide),’ said the Research & Technology Manager of Crop Care at Croda. ‘Why isn’t that being brought into the equation when we’re talking about carbon and agriculture?’
Martin Collison expanded on this point. He emphasised the need to separate carbon emissions by system – such as extensively grazed livestock animals and those fed on grain – and to account for systems that sequester carbon in the soil. The co-founder of agricultural consultancy Collison & Associates also pointed out the problem with bundling all our greenhouse gases as one.

Greenhouse gas emissions are sometimes unhelpfully bundled together, instead of being separated by gas and agricultural system.

‘We count methane in the same way we emit carbon,’ he said. ‘When we emit carbon, it’s in the atmosphere for 1,000 years, but with methane it’s 12 years. The methane cycle is a lot, lot shorter.’

And the difficulties with the statistics don’t end there. For example, countries often announce impressive emission reductions without taking trade into account. This, of course, gives the figures a greener gloss.

‘To me, there's a need to be more up front with a lot of the data because agriculture and food are traded around the world,’ he added. ‘A lot of the emissions data ignore what we trade.

‘In the UK, we make big claims about how fast we’ve progressed with carbon emissions, but if you look at what we consume, the progress is much much slower. The things we produce less of, we import.’

>> SCI was at COP26 too! Read about the role of chemistry in creating a greener future.

Full of hot air?

Emissions trading also serves to blur the picture. For Jeraime Griffith it is an unsatisfactory solution. ‘In terms of carbon trading, we have cases where the higher emitters continue producing in the way they’ve always been producing,’ he said.

‘It doesn't bring in any restrictions on the amount of carbon they emit; it just shifts the problem somewhere else. I don't know how carbon trading benefits us getting to Net Zero. It just seems to be kicking the ball farther down the road.’

Is emissions trading part of the solution or part of the problem?

So, when you take into account 1. emissions trading, 2. the absence of food imports in data sets, 3. the bundling together of different greenhouse gases in emissions figures, and 4. the failure to take carbon sequestration into account, it’s clear that many of the statistics we receive are incomplete.

‘There’s lots of complexity behind the numbers and we tend to lump all of it together,’ Collison said. ‘There’s a need to go much much further.’

At COP26, Nikita Patel co-hosted the Next-Gen debate, where an inspiring group of young people discussed how chemistry is tackling climate change. The PhD student at Queen Mary University of London shares her experience.

While the United Nations Climate Change Conference (COP26) may be over, there is still plenty to be done in the fight against climate change. We’ve seen what can be achieved when we work together and no doubt science will play a key role.

On Thursday 4 November, I had the privilege of co-hosting the Countdown to Planet Zero Next-Gen debate organised by SCI to showcase the work being carried out by our young and innovative scientists to tackle climate change. It was a real pleasure to share the stage and hear from some great scientists, exploring the themes Fuels of the Future, Turning Waste into Gold and Engineering Nature. The event gave the audience the opportunity to question and challenge the panel members on their climate change solutions.

Panel L-R: Dominic Smith, Natasha Boulding, Clare Rodseth, Jake Coole, Nikita Patel, Oliver Ring (Brett Parkinson joined virtually).

While I was feeling nervous about my hosting duties, I was very excited at the same time as I knew how important it was to educate the audience, whether they were members of the public or aspiring scientists, on how science is crucial in battling the climate emergency.

An important part of my role as a host was to ensure the incoming questions and comments were understood by all, given the mixed audience attending. This highlighted how essential good science communication is to prevent misunderstandings and the spread of misinformation.

It was brilliant to see how engaged the audience were from the flurry of questions that came in during the session, so much so that we didn’t manage to get through all of them! There were a wide variety of questions aimed at particular panellists but also towards the panel as a whole. It was thought-provoking to hear how scientists from different backgrounds offered their own perspectives on the same topic.

4 November was also Energy Day at COP26 and the atmosphere was buzzing! I learnt a lot from attending the Green Zone, not only from our panellists but from all the exhibitors present too. I appreciate the small, individual actions we can each take that will make a difference but also the need to work together to achieve the common goal of fighting climate change. It was clear to see how science and business go hand in hand to provide solutions to society and how interdisciplinary collaboration is key.

The result of our poll question: ‘Do you think that science is pivotal in providing climate change solutions?’ spoke for itself, with a resounding yes from 100% of the audience participants! This was a very positive outcome and showed that it is not all doom and gloom when it comes to discussing the climate crisis.

On a personal level, I'm going to continue implementing some simple changes like using public transport more, eating more vegan food and flying less and aim to keep the discussion going with my peers as the climate emergency is far from over.

SCI team, panellists and hosts.

I hope the youth panel event has inspired the next generation of scientists and showcased some of the exciting work that is going on behind the scenes which people may not realise and ultimately, that there is hope in science.

A group of inspiring young scientists took centre stage at COP26 on 4 November to show how the next generation of chemists is finding tangible climate change solutions.

In a day dominated by what countries pledged to stop doing at COP26, such as pursuing coal power and financing fossil fuel projects overseas, it was refreshing to learn about low-carbon technologies and the young people driving their development. At the Next Gen forum, we heard from an array of young chemists, all associated with SCI, who are at the sharp edge of this change.

We heard from Brett Parkinson, Senior Engineer of Low Carbon Fuels and Energy Technologist at C-Zero, who is working on commercialising a way to decarbonise natural gas. The California-based company’s technology converts the natural gas into hydrogen and solid carbon to provide a clean energy source while sequestering the carbon; and the aim is to have this process up and running next year.

Natasha Boulding is building towards Net Zero a different way – with a greener concrete. The CEO and Co-founder of Sphera has developed a lightweight carbon negative additive using waste plastics that aren’t currently being recycled. She says the company’s blocks are the same strength and price as existing concrete blocks, but with 30% more thermal insulation. There is also the added benefit of reusing waste materials that would otherwise have gone to landfill or been incinerated.

Another solution discussed by Dominic Smith, Process Development Engineer at GSK, reduces energy consumption through green chemistry. He is trying to find greener ways to make medicines using enzymes. These enzymes, which can be found in plants and soil, replace chemical synthesis steps to cut energy consumption during processing and reduce hazardous waste.

Panel (left to right): Dominic Smith, Natasha Boulding, Clare Rodseth, Jake Coole, Nikita Patel, and Oliver Ring (Brett Parkinson spoke via video link).

It was apparent from the discussion that many solutions will be needed for us to reach our climate change targets. On the one hand, Jake Coole, Senior Chemist in Johnson Matthey’s Fuel Cells team, is working on membrane electrode assembly for hydrogen fuel cells to help us transition to hydrogen-powered buses and trucks.

At the same time, Clare Rodseth, an Environmental Sustainability Scientist at Unilever, has been using lifecycle assessments to reduce the environmental impact of some of the 400 Unilever brands people use all over the world every day. For example, this work has helped the company move away from petrochemical ingredients in its home care products. ‘Even small changes,’ she said, ‘have the potential to bring about large-scale change.’

Incremental change

However, for each of the technologies discussed, barriers remain. For Coole and co., having a readily available supply of hydrogen and charging infrastructure will be key. And for Dominic Smith and his colleagues, the use of enzymes in green chemistry is still in its infancy; and getting enzymes that are fast enough, stable enough, and produce the right yield is difficult. Nevertheless, he noted that manufacturers are now using enzymes to produce the drug amoxicillin, reducing the carbon footprint by about 25%

And some things will take time to change. Natasha Boulding noted that concrete is the second most used material in the world after drinking water, and we simply can’t create many green technologies, such as wind turbines, without concrete foundations.

She said the construction industry is quite traditional but also pointed to perceptible change, with the green concrete market growing and companies becoming increasingly aware of their carbon footprints.

Collaboration was seen as crucial in producing climate change solutions.

The reality is that global action on climate change is recent. As Brett Parkinson said: ‘the main reason we’re talking about it now is that there’s a driver to do it. Until the last decade, the world hadn’t cared about CO₂ emissions. They just talked about caring about it.’

How pivotal is science in all of this?

So, what could be done to make climate action more effective? For Parkinson, effective policy is key. He argued that if the market isn’t led by policies that encourage low-carbon innovations, then it won’t work as needed. ‘It all starts with effective decarbonisation policy,’ he said. ‘Legacy industries are very resistant to change. If you don’t have strong and consistent policies… then they’re not going to adapt.’

Another key to our low-carbon evolution is collaboration, and the SCI provides a confluence point for those in industry and academia to work together to produce innovative, low-carbon products. As Clare Rodseth said: ‘Collaboration is really important – linking up people who can actually come together and address these problems.’

As the discussion came to a close, you had the impression that the debate could have gone on for much longer. ‘Hopefully, we’ve demonstrated that there is action, and it’s being driven by young people like our panellists today,’ summarised Oliver Ring, the event’s co-Chair, before asking for the result of the audience poll.

The question: How many of those watching believed that science is pivotal in providing climate change solutions? 

The answer: Just the 100%.

>> Thank you to Johnson Matthey for sponsoring the event, to the speakers for sharing their time and expertise, and to co-chairs Nikita Patel and Oliver Ring for doing such an excellent job.

This Thursday at COP26, an inspiring panel of young scientists will discuss innovations that will help us mitigate climate change. So, what can we expect?

Millions of young people are frustrated by climate change inaction. Indeed, according to a University of Bath study, 60% of the next generation feel overwhelmed by climate anxiety. Often, the proposed solutions seem vague and intangible – well-intentioned ideas that drift away when the political winds shift.

And yet, when you see the ingenuity of young scientists, business people, and activists, it’s hard not to be excited. Undoubtedly, politics and our legal system will play a huge role in the drive to reach Net Zero, but arguably science will play the biggest role in transforming the way we live. Just think of the falling cost of generating solar power, improvements in battery chemistry for electric vehicles, the development of sustainable construction materials, and the rapid rollout of Covid-19 vaccines.

Tangible solutions

This Thursday at COP26, SCI will host the Next Gen youth forum event where the panellists discuss the climate change solutions they are working on right now and how they are being applied by industry. In the Countdown to Planet Zero roundtable, these scientists – drawn from within SCI’s innovation community – will explain their work to a global audience and the impact it will have on climate change.

They will discuss innovation in three key areas: topics of fuels of the future, turning waste into gold, and engineering nature.

The next generation has mobilised and is creating solutions to help avoid climate change disaster.

The panel will be chaired by two very capable young scientists. Oliver Ring is Senior Scientist at AstraZeneca’s large-scale synthesis team and Chair of SCI’s Young Chemists’ Panel, and passionate climate advocate Nikita Patel is a PhD student at Queen Mary University of London’s Centre of Translational Medicine and Therapeutics and STEM Ambassador for schools.

The other panel members include Clare Rodseth, of Unilever’s Environmental Sustainability Science team, who brings lifecycle analysis to product innovation to make products more sustainable.

Jake Coole, Senior Chemist in Johnson Matthey’s Fuel Cells team, is involved in the scale-up of new processes and next generation manufacturing, and Dominic Smith, Process Development Engineer at GSK, who is interested in engineering biology to create sustainable manufacturing processes.

Also present will be Dr Brett Parkinson, Senior Engineer of Low Carbon Fuels and Energy Technologist at C-Zero – a California-based startup that works on the decarbonisation of natural gas. In 2019, Brett was awarded an SCI scholarship for his research.

The lineup also includes Dr Natasha Boulding, CEO and Co-founder of Sphera Limited, a speciality materials company that has created carbon negative concrete blocks made from aggregate including waste plastic. According to Natasha, whose company also won SCI’s Bright SCIdea challenge in 2019: “In terms of combating climate change, interdisciplinary collaboration is the key. No one discipline has the answer to solve our biggest challenges – but together diverse minds can.’

Sarah Davidson has made impressive strides in a short space of time. She has risen to Group Sustainability Coordinator for global Research and Technology at speciality chemicals firm Croda and won the Young Ambassador Award at this year’s Chemical Industry Awards.

In the first blog in our Women in Chemistry series, we caught up with Sarah for a chat on embedding sustainability in the workplace, the need for more diversity in senior roles, and the best bit of advice she received.

Tell us about your career to date.
I loved chemistry at school, so I started off by doing a Master’s in Chemistry at the University of Sheffield. During the course I did a placement year, which was my first taste of working in industry. Once I finished my degree, I was torn between staying in academia and doing a PhD or going into industry. I chose to go into industry because I had enjoyed my placement year so much and saw where I could make an impact.

I was accepted onto Croda’s Graduate Development programme, where I had three placements around the business. Croda is a speciality chemicals company, so my placements included working as an applications scientist and synthetic chemist. However, it was my placement working with the Sustainability team that I loved the most.

After the Grad Scheme I became Group Sustainability Coordinator for Global R&D. This combined my experience in R&D and sustainability in a brand role that didn’t exist in Croda before. This role allows me to use my technical knowledge and understanding of the way the global team works to enable those responsible for Croda’s new product innovations to include sustainability as an integral pillar in new product development.

What does your day-to-day role involve?
In my role, my main focus is on getting our scientists to think about sustainability during product and process development. At a fundamental level this requires me to change their mindsets around sustainability, getting them to see it is important to what we do and understand what it means.

To do this, I have developed a number of tools including checklists, clearly defined procedures and training documents. I have been working to get these new procedures adopted over the global R&D team by fitting them into existing protocols. Another part of my role is to support our corporate targets and I am part of a number of working groups to do this.

One working group looks at how we define a consistent methodology for Life Cycle Assessments or LCA. In this group I have been doing research to understand the current methods around LCA, and what our customers want in terms of sustainability data. I also help gather data to show where we are up to with these goals, so we understand what actions we need to take to move forward. On a day-to-day basis I will have meetings to discuss the projects I am involved in, conduct research and reach out to other teams and functions to see what they are working on too.

Which aspects of your job motivate you most?
For me sustainability is the future, not only for the chemical industry but for the world. Knowing that I am having a positive impact on sustainability in my role is what motivates me the most. I try to live a sustainable life, and what I do at work is just an extension of that.

What personal challenges have you faced and how have you overcome them?
To embed sustainability into our ways of working, I need to change people’s mindsets, and subsequently their behaviour. Seeing this change in people is incredibly rewarding. However, it is also one of the biggest challenges. Some of our teams have been working in the same roles for decades without any change. So, it is my job to make these changes easier for them to adopt and persuade them of the benefits in doing so. To overcome this challenge, I have had to work on my influencing skills and know what will work with the audience I am speaking to.

What is the greatest future challenge for people in your industry and how could this be addressed.
Sustainability, and addressing the issues we face as a result of climate change, are some of the biggest challenges we will face as an industry. We are in a lucky position that we can achieve a competitive advantage with sustainability, but our main goal is to protect our planet. This gives us a big opportunity for collaboration where we may not have had one before. I think we can only solve this challenge by collaborating across the supply chain, across country borders, and between industry and academia.

>> Not everyone takes the standard career path into chemistry. Take a read of Claudio Laurenco’s unusual, inspiring story.

Which mentors have helped you along the way and how did they make a difference?
I feel like I have a long list of mentors and am very lucky to be able to call on so many people for advice. The best thing I have learnt from them is to pursue what I enjoy most, as people will be able to see my passion. This will help me move forward in my career. Having mentors who have confidence in me and my ability has helped me build my own confidence, something which I can lack from time to time. My mentors are great sounding boards for ideas, whether that is to do with things I want to try in my job or on the direction of my career.

What is the current state of play within your sector with respect to equality, diversity, and inclusion – and is enough being done to attract and retain diverse talent?
I don’t think so. We need to do more to attract and retain diverse talent. We seem to be relatively diverse and inclusive at an academic level, which disappears in industry. There must be a reason for this. There may be bias within recruitment processes, or within job descriptions for senior roles, which means there is less diversity as you move up in organisations. We need to make sure that there are equal opportunities within industry for everyone and make sure everyone has a path to progression that works for them.

Is there any advice you would give to young professionals starting out in your area, especially young women?
Understand where you are different and use that as your advantage. Everyone has a unique lived experience that they bring with them into all situations. As women we have a different perspective to men. This doesn’t mean it is less valuable, it is just different. When you feel like you are in a minority as a woman, or are not being listened to, it is important to remember that our opinions are equal regardless of our background, gender or ethnicity. You have the same right to share your views, as the majority do theirs.
