King’s Energy: The Noor Ouarzazate Solar Complex

July 26, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

We’ve all wondered if it’s possible to cover the Sahara Desert in giant solar panels to resolve our renewable energy issue. No doubt you will have seen utopian constructions of what this could look like. For instance, David Attenborough’s A Life on our Planet provided an example of how a future powered by renewable energy could look. But in Morocco, that future is already here, and they’ve taken that interest in Sahara solar panels seriously too. Check out this image of the world’s largest concentrated solar power project, the Noor Ouarzazate Solar Complex:

When was it built?

Construction began in May 2013. There have since been two expansion productions also commissioned, one in 2018 and one in 2019. It was funded by the Moroccan Agency for Sustainable Energy at the cost of a cool $3.9 billion, though this funding came from several investors, including the World Bank.

How does it work?

Here’s the cool part! Noor I uses Concentrating Solar Power (CSP) to produce energy. Essentially, this means that a series of mirrors divert sunlight into something that retains that energy to be used later. The unique part about Noor I is that it uses molten salt to store energy, meaning that energy collected during the day can also be released at night.

The complex has upgraded on this for Noor II and III, which can store energy for up to 8 hours. Noor II uses a slightly different technology: parabolic troughs, or concave mirrors to the rest of us, to reflect the sun’s rays. Noor III, meanwhile, has a solar tower that collects the energy reflected from the mirrors (pictured).

Finally, Noor IV, which has not yet been commissioned, will use photovoltaic panels as we know them, so we will be one step closer to finding out what will happen if we fill the world’s hottest places with solar panels.

How much energy does it produce?

Noor I alone produces 370GwH per annum, with Noor II producing 600GwH and Noor III 500GwH and combined, they cover 6,178 acres. To put that into context, global energy usage was 171,240TwH in 2019. It would seem then that Noor is just a drop in the ocean, but consider that the Sahara Desert is 2.273 billion acres. It would take 116.5 Noor’s to supply the world with renewable energy based on 2019 demand, which would require 719,674 acres of the Sahara… Now, that really is just a grain of sand.

A couple drawbacks and limitations include the need to regularly clean the solar panels (even more so because of the sandy environment), which requires large amounts of water and the challenge of transporting power over great distances and political will.

King’s Energy: “Big Battery” Technology

July 19, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

In last week’s blog post, we discussed the UK’s challenges when it comes to adopting renewable energy. One of these is combatting intermittency and increasing the efficiency of wind and solar power. The eagle-eyed among you may have spotted a potential solution: batteries. No, not the Duracell Bunny. Big batteries. Batteries for storing energy. Intrigued? Read on to discover more.

What is “big battery” technology?

Think of your phone battery. You plug it into the mains, it charges, and the charge is retained for a period of time. The theory here is very similar. Instead of having periods of over-and undersupply, renewable energy can instead be stored in large-scale battery facilities. It can then be fed back into the grid.

What are the advantages?

The main advantage of “big battery” technology is that they minimise energy wastage, making investments in renewables far more attractive. Batteries can even out the energy harvested by renewables over the year, so your household isn’t dependent on 365 days of sun. In addition, if you have one in your own home, the energy will be stored rather than returned to the grid, decreasing your reliance on the grid and reducing the stress on the grid itself. Another advantage is that even with limited capacity, battery storage can be used to power homes via the grid in emergencies or in times of power outages instead of using natural gas.

Is it available already?

Yes and no. This technology is available for home use (for those who generate their own electricity) but is not yet widely available on an industrial scale. However, that is changing. California, for example, has a 300-megawatt lithium-ion battery already up and running and another 100-megawatt battery due to become operational this year. Because of these initiatives, more funding is being allocated to developing this technology.

What about the UK?

The UK and Europe as a whole have been a little slower to become convinced by the merits of this technology, and so there are no fully operational battery storage facilities in the UK yet. However, the development of several facilities is underway. The largest of these is in Essex, on the Thames Estuary, where InterGen has gained planning permission for a 320MW site at the cost of £200m. It will also have the potential for further expansion, up to 1.3GW. This would make it ten times the size of other projects also underway in the UK and able to power over half a million homes in the event of a power outage.

So, “big battery” technology really is just big batteries. It remains to be seen just how effective they are in the long term. Still, it seems a crucial element of transitioning to renewable energy sources will be to store this energy when there is no demand for it, and batteries are currently one of the best ways to do so.

King’s Energy: The renewable energy challenge and the National Grid

July 12, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

We’ve given a lot of information on this blog recently about renewable energy and how commendable it is that the UK (and King’s, of course) are in the process of switching to renewable sources. However, this cannot happen overnight, and it does put considerable strain on the existing energy network as we go through the transition. So that got us thinking – how many people actually know how all this works? The answer is hopefully everyone who has read this post, so read on to find out!

How is electricity generated?

As you will probably know, energy is typically generated by producing steam. This steam then turns a turbine, which in turn powers a generator and boom we have electricity. Although there are other methods to turn those turbines (falling water, wind, etc.), steam remains by far the most popular.

How does the National Grid work?

The National Grid is a system of power lines, pipelines, interconnectors and storage facilities. Once the energy is generated, the role of the National Grid is to deliver it to homes around the UK. Within the network, many Distribution Network Operators (DNOs) distribute the electricity locally where and when needed.

What is the challenge with renewables?

Official demand for renewable energy is increasing, and it poses a monumental challenge to the National Grid. As such, not only does the Grid require regular and costly maintenance, but it is now being upgraded on a never-before-seen scale. In addition to this, the demand for energy itself is also greater than ever. Since September, this has led to the National Grid Electricity System Operator (NGESO) issuing four Electricity Margin Notices (EMNs). These are essentially warnings that there is not enough reserve energy to guarantee continued supply. To put that into context, one such notice was issued in the UK over the previous four years.

What is the solution?

Half of the problem is demand, so if we as individuals can reduce our energy demand even slightly, we will also reduce the pressure on the Grid itself. Besides this, some other technical solutions may become viable in the future, for example, battery storage. These are currently available in your home, and if you generate your own electricity (one to bear in mind for the future), they are a worthwhile investment. However, using them on a large scale is not yet feasible, though this would go some way towards having a permanent baseline. Reciprocating engine generator technology and black-start gas turbines are other technological advancements that could also support this.

In short, we all like things to be done quickly, but in the world of energy, the transition to renewables is a slow and complicated process. In the short term, we can all do our part by reducing our consumption, easing the pressure on the National Grid and making the renewable transition far smoother.

King’s Energy: The Climate Change Committee 2021 Progress Report – Findings and Recommendations

July 5, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

Welcome back to the King’s Energy blog post! Last week the Climate Change Committee (CCC) published their 2021 Progress Report to Parliament – read on to see what they found and their recommendations for the future.

Energy Use in 2020

Global energy use fell by 4% in 2020 compared to 2019 levels, mostly accounted for by significant declines in more “advanced” economies. In addition to this welcome decline, the energy we are using has become cleaner as we are also becoming gradually less reliant on fossil fuels as an energy source. According to the report, oil use has fallen by 9% – predominantly due to less demand for oil for transport. Electricity demand also decreased, meaning coal consumption fell by 4%, while gas usage also fell by 2%. However, these figures do not tell the full story. Not only has electricity demand fell, but 29% of the electricity used derived from renewable sources – that’s a 27% increase on 2019 levels. To put that into context, that is the largest growth rate on record, and it means that the total low-carbon generation share is now 39%.

Forecast for 2021

All of that sounds great, so what’s the catch? Well, these figures have been impacted in no uncertain terms by the pandemic and, with the effects of that expected to die down (fingers crossed) over the next year, the CCC are not so optimistic for 2021. They expect energy usage to bounce back, rising 4.5% in 2021, which would bring it 0.5% above 2019 levels. Equally, CO2 emissions are expected to rise by around 5%, falling just short of 2019 levels. However, there remains significant uncertainty about these predictions as it depends on the course of the pandemic and how countries recover from it.

Future Recommendations

Among their 32 pages of recommendations, the CCC advise Parliament of the following when it comes to energy:

  • Consult on reforms to electricity pricing to remove disincentives to electrification by 2022.
  • Consider the introduction of a carbon tax aimed at curbing rising emissions from energy from waste by 2022.
  • Create a clear incentive for manufacturing facilities to switch to low-carbon energy sources by 2023.
  • Improve the collection and reporting of industrial decarbonisation data to allow for progress to be monitored more effectively, particularly on energy and resource efficiency by 2022.
  • Provide a stable long-term policy framework to support sustained energy efficiency and heat pump growth as a priority.
  • Implement improvements to the Energy Performance Certificate by 2022.
  • Improve the consumer charging experience and making smart charging accessible, appealing and cost-effective for as many electric vehicle users as possible as a priority.

So there you have it. In short, progress has been made over the past couple of years. Still, we have a duty as individuals to build back from the pandemic in a more energy-conscious way. At the same time, we are also reliant on the authorities to commit to the changes listed moving forward. Read the Climate Change Committee’s 2021 Report to Parliament here.

King’s Energy – Transport and energy: what’s the link?

June 28, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

London is famed for its red double-decker buses, but those of you with a keen eye may have noticed that some of these are turning green… According to Transport for London (TfL), London’s 9,500-strong bus fleet attracts a daily ridership of 6 million people on a weekday across 673 routes. In this blog, we explore the link between transport and energy and what is being done to reduce emissions in this area.

The relationship between transport and energy

It is simply impossible to talk about energy without mentioning transport. The transport sector was responsible for over 24% of global emissions in 2016, and this figure has been growing year on year. In the UK specifically, this number peaked in 2007 before a slight decline but has been rising again since 2013. The root cause of the problem is unquestionably road vehicles, which account for 72% of global transport emissions.

The concern with transport is not limited to vehicle emissions either. The transport sector is heavily reliant on oil as an energy source, with over 53% of global primary oil consumption in 2010 being used to meet 94% of the total transport energy demand. The good news? This reliance seems to be decreasing. Energy consumption by the transport sector has shrunk to 31% in the years since. There is, however, still a long way to go.

What is being done?

In London, the focus has very much been on targeting these road vehicles. You may have heard of certain initiatives such as the Congestion Charge Zone, the phasing out of diesel taxis or “Ultra-Low Emission Zones”. While these have had a positive impact, more action is needed, and more action has been promised.

Mayor Sadiq Kahn has committed to ensuring 80% of all Londoner’s trips be made by foot, bicycle or public transport by 2041. To achieve this, there are plans to expand the cycle network and continue to enforce “Ultra-Low Emission Zones” and building on the Toxicity Charge (T-Charge). This would include incorporating central London into a “Zero-Emission Zone” by 2025 to be expanded to a London-wide zone by 2050. Additionally, from next year all new double-decker buses will be hybrid, electric or hydrogen, while it is hoped that the entire bus fleet will be completely emission-free by 2037.

What can you do?

As a London resident, you can do your bit by avoiding driving in the city (although we’re sure not many students plan on driving around London). Of course, we would encourage walking or cycling (though always carry an umbrella!) for short distances, and public transport for longer ones.

What is King’s doing?

Tune in to our #TakeoverTuesday tomorrow (Tuesday 29 June) on the King’s Sustainability Instagram. We will be filling you in on what King’s is doing to help.

King’s Energy: Smart homes – how energy-saving are they?

June 21, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

I’m sure many of you have seen adverts or promotions for some form of “smart home” technology. They are becoming increasingly popular and in-demand, but is this just because they seem like a cool idea? Or do they actually save energy? We’ve done the research for you, so read on and find out!

What are smart homes?

Simply put, smart homes are residences that use internet-connected devices to enable the remote monitoring and management of appliances and systems, such as lighting and heating. Many new homes are being built with the capacity for them to become smart homes, while older homes can be retrospectively fitted with the right technology.

What makes them “smart”?

Smart homes allow you to monitor and control anything in your home which is linked to your WiFi. That may sound like you’re the smart one there, but smart homes do have some features which make them truly intelligent. For example, using sensors, they can tell when somebody is in a home or a room and control the lights or heating accordingly. They can also track your behavioural patterns to identify the perfect amounts of water or energy for certain activities. Based on these patterns, many smart homes will also offer you recommendations on saving energy every day. That’s truly smart.

Can they help save energy?

The simple answer is yes, but it depends on the individual. A smart home can only provide information and optimise with the tools at its disposal. It is up to the homeowner to give it more tools to use and a better environment to use them in. Put simply, if your water meter is not linked to your smart home, then it will have no impact on your water usage. It can take time to get everything hooked up and become comfortable with all the features.

What can be done to help my smart home?

Several things can be done to make homes more suitable for smart home technology, so these may well be worth looking out for when it comes to investing in your first home:

  • Insulation – A properly insulated home will make heating and cooling much easier and more energy-efficient, thereby making life much easier for a smart home.
  • LED bulbs – As we mention most weeks on this blog, LEDs use much less energy than most other types of lightbulbs. They are also extremely durable and can be easily connected to smart homes.
  • Solar panels – An expensive investment, we know. However, this one shows that while you can save energy, if your energy is still sourced from fossil fuels, for example, then the environmental benefits are minimal. Solar panels will also reduce reliance on grid electricity, and even more so if you also invest in a home battery which will retain and store any excess energy. So, if you are thinking of purchasing a smart home, think long-term and make sure your home is ready before making that investment.

So, there you have it, smart homes have the potential to be extremely effective in terms of saving energy, but much of that depends on how you use and complement it. If you have seen them advertised and dream of having one in your future home, then don’t worry; they can be really great for the planet, but you should ensure the correct infrastructure is in place before taking the plunge.

King’s Energy: Some good news – Sale of halogen bulbs to be banned in the UK

June 14, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

Okay, this story was run a few days ago so it’s technically not breaking news.

You may remember our article about lightbulbs, namely incandescent, halogen, fluorescent and light-emitting diode (LED) bulbs. Last week, as part of a series of climate change plans, the UK government announced that halogen bulbs will be banned in the UK from September, and fluorescent lights will follow shortly thereafter. This new ban builds upon EU-wide rules in 2018 banning old-fashioned incandescent lightbulbs.

Why are they being banned?

While halogen bulbs are one of the cheaper options on the market, costing on average £2, they do not compare favourably to other market alternatives in terms of energy. A halogen bulb uses 70W to produce 1600 lumens. That is 30W less than traditional bulbs, but around 6 times the energy usage of LEDs. Further, they have an average lifespan of just two years, so you can imagine the amount of waste generated.

Overall, halogens are no longer the most energy-efficient bulb on the market and this change will go towards helping the UK achieve its environmental goals. In fact, according to Department for Business, Energy and Industrial strategy, this move will cut 1.26 million tonnes of carbon emissions a year – equivalent to removing half a million cars from the UK’s roads.

What about Compact fluorescent lamps (CFL)?

CFL lighting will also be phased out in the new plans, by September 2023. While these were heralded for their energy efficiency when they were first introduced on the market (they are more energy-efficient than halogens, using just 25W for 1600 lumens), LEDs quickly swept in and took their place as most energy-efficient lightbulbs.

Keep an eye out when you return to the office as the CFL strip lighting may just have been replaced. Can you notice the difference?

How does this affect me?

The ban refers to the sale of the bulbs, not the owning of them – so don’t worry, your kitchen spotlights will not suddenly become illegal. Overall, the shift away from traditional lightbulbs will also save households across the UK money on their energy bills.

What is the alternative?

Our preferred alternative, and seemingly that of the UK Government, are LEDs. They use just 16W of energy to produce 1600 lumens, while they have a life span of 20+ years. Therefore, although the initial cost of LEDs can be high, they tend to save between £45 and £75 in energy over ten years. And if you’re saving money, using less energy and producing less waste, we at King’s Energy are happy.

King’s Energy: Grant funded – ‘Mapping the Food Waste-Energy-Water-Emissions Nexus at Commercial Kitchens’

May 31, 2021 /

This guest blog comes from Julie Allen, Energy Manager at King’s.

In June 2020, KCL (along with Arizona State University, Dublin City University and City University of Hong Kong) submitted a grant application to GCSO (Global Consortium of Sustainability Outcomes) for a proposal to create a Certification for Sustainable Kitchens – and we got the grant!

In March this year, our interim findings were published in the Journal of Cleaner Production, in a paper entitled ‘Mapping the Food Waste-Energy-Water-Emissions Nexus at Commercial Kitchens: a systems approach for a More Sustainable Food Service Sector.’

I’m a published Author!

To break it down, here is a little background.

I have many years of experience in the commercial catering sector. There are always efforts to address food waste, OR energy consumption, OR water consumption, but never anything to look at the whole life cycle of the food going through a commercial kitchen. So that’s what we did. Our role at King’s was to provide energy consumption data from King’s Kitchen (which is excellently managed!). We also had to manage the expectations of our colleagues in other universities, as there can be a huge difference between theory and practice.

The paper looks at the impact of food on the climate – from the water used to grow the food, the transportation carbon miles, the energy to grow and prepare it, the amount of waste generated (not only from food preparation but also packaging) – and an analysis of a particular meal from field to fork. It’s been a fascinating journey looking at how different countries, organisations and sectors produce and sell food, even down to expectations around metering (we were asked to meter each tap until I explained it would take the whole grant!).

It’s been a fantastic journey, which isn’t over yet – we’ve had an extension until December 2021, so watch this space for further developments!

King’s Energy: A guide to eco-friendly energy suppliers in the UK

May 24, 2021 /

This guest blog comes from Mason Cole, MA Politics and Contemporary History student and Sustainability Champion Assistant (SCA), supporting the King’s Energy Team.

If you’re interested in learning more about how you can both switch to cheaper, fairer and more environmentally-friendly energy and support your community in doing so, check out the Citizens UK Fair Energy Campaign, as well as how student group King’s 4 Change is supporting the campaign at King’s. 

If you’ve kept up with our blog you will know we have devoted a lot of time to making switching energy providers as easy as possible for you. Of course, we would also prefer energy efficiency to be at the forefront of your mind when switching. As such, we’ve selected a few companies to review so you don’t have to!

How do I know if a company is eco-friendly?

Unfortunately, greenwashing is rife, so it can be difficult to make sure you’re not just falling for a marketing ploy when you think you’ve found the perfect company. Here are some things to look out for:

  • Carbon Offsetting – Many companies which call themselves “green” simply offset the carbon they produce, for example by planting trees. We have criticised this in the past but if done alongside other measures it can also be a positive.
  • Energy Source – Companies are obliged to tell you where their energy comes from. As much as possible, look for tariffs that offer renewable energy.
  • Tariff – As mentioned, the energy source often depends on the tariffs offered. Make sure to check these to see which best fit your needs in terms of usage, cost and of course, efficiency.
Octopus Energy

Octopus has a wide range of tariffs which can be confusing for those who haven’t read our blog! However, if you choose the “Super-Green” tariff then they will provide you with 100% renewable energy in addition to carbon offsetting. To help with costs they will also reward you and a friend with £50 when you switch.

Green Energy UK

Green Energy UK are the only UK energy company to offer 100% “Green” gas as well as 100% renewable energy so in that sense they are the best pick. However, they are on average 38% more expensive than other suppliers so get a quote before you make the decision to switch.

Outfox the Market

Outfox the Market is the cheapest supplier of renewable energy. They offer 100% renewable energy, from wind power, but because they are less established than their competitors they are also lower-rated by customers. Make sure to read reviews online before deciding in this case.

Bulb

One of the more-established eco-friendly energy companies in the UK, Bulb offer 100% renewable energy, from hydro, solar and wind power, as well as 100%  carbon neutral gas. They are also, on average, 17% cheaper than the “Big Six.”

Ecotricity

Ecotricity is the UK’s vegan energy supplier, offering 100% renewable energy. They are approved by the Vegan Society and support anti-fracking campaigns as well as Extinction Rebellion, so if you are passionate about helping environmental causes then they could be the right provider for you. However, they are relatively expensive so again make sure to get a quote before deciding.

So there you have it, these are the 5 we selected to look at this week. If you know of another environmentally-friendly supplier, let us know in the comments below!

How to reduce, reuse, and recycle your way to a more sustainable lab

May 20, 2021 /

This guest blog comes from Dr Nicola Harris, postdoctoral researcher in the Department of Chemistry

Lab-based research is not sustainable. If you work in a lab, think about how many tips, gloves and plastic tubes you throw away every day and then think about how many labs in the world do the same. In fact, labs are estimated to be responsible for 5.5 million tonnes of plastic waste per year. Unfortunately, alternatives to single-use plastics in the lab can be hard to come by or are labour intensive, and safety concerns mean that clinical and contaminated waste needs treating – usually by energy-intensive incineration or autoclaving (or both).

As well as the need to reduce plastic waste, CO2 emissions, electronic waste and over-consumption are also all problems with lab research. Labs use 10 times more energy than offices and 4 times more water.

We are all familiar with reduce, reuse, recycle at home – but how can we apply these in the lab? Here are some tips to help your lab move towards being more sustainable while our suppliers catch up. These tips are primarily based on my own experiences in life sciences research – I do protein-based research, with a lot of molecular biology and RNase-free work. Check out My Green Lab and LEAF for more tips!

Reduce

Probably the most important step to take right now, with the biggest impact.

New equipment – do you really need it? Can you borrow someone else’s? Does another group need something – can you share and buy it together instead of getting one each?

Reagents. If you need something, double check you don’t have it already tucked away at the back of a shelf before ordering more (a lab inventory is very useful for this). Do other groups have some you can borrow?

Consolidate autoclave runs. Does it only run when full?

Reduce lab energy consumption. Turn Ultra-Low Temperature (ULT) freezers up to -70 °C, using around 30 – 40 % less energy than -80 °C. Regular defrosts will also help freezers consume less energy. Shut fume hood sashes when not in use – a single fume hood uses the same amount of energy as a household. Turn other equipment off when not in use – most things don’t need to be on overnight and at the weekend (turning off also increases the lifetime of the equipment).

Use pipette tip refills instead of new boxes. You can autoclave refilled boxes yourself, and tip refills come in RNase-free filter tip varieties too!

Improve sterile technique. Reduce plastic waste by using a glass or metal cell spreader – these can be sterilised with ethanol and a flame and are as sterile as a plastic disposable spreader (in my opinion more sterile, as people’s hands go in and out of the packet for the disposable ones!).

Think about what you are doing and why. Protein research does not really need tips to be sterile, for example. Buffers generally don’t need to be filtered and autoclaved, and the purest water isn’t necessarily required.

Reuse

Glass alternatives. Many single-use plastics have glass alternatives that can be washed and reused. Buffers can be made in glass bottles instead of plastic tubes, and cell cultures can be grown in autoclaved glass bottles. Reusing glass many times over will result in fewer emissions, even if it needs autoclaving. Remember that disposal of contaminated plastics requires autoclaving or incineration anyway – so you might as well autoclave glassware instead.

Plastics can be washed out and reused. This may not be an attractive option, however, as it is fairly labour intensive.

Re-home old equipment. If you need new equipment, there are options to buy equipment that other labs no longer need (for example from Warp It and Richmond Scientific). Similarly, if you no longer need some equipment then it can be used in someone else’s lab.

Recycle

Unlike at home, recycling in a lab can be difficult. Waste contractors can be unhappy about taking waste that could be contaminated – but it is worth talking to them about it if you are able to.

Plastic reagent bottles. Check the resin type (1, 2 and 5 are most commonly accepted), remove the hazard label and wash out thoroughly for recycling.

Uncontaminated card and paper. The easiest thing to recycle from labs – packaging in particular.

Take-back schemes. Lots of companies do take-back schemes – for example, New England Biolabs take back their cold shipping polystyrene boxes, and Starlab take back their pipette tip boxes and tip wafers. Check with your suppliers to see if they offer any take-back schemes (or encourage them to start one!).

Ice packs. Most life sciences labs will be familiar with the huge pile of ice packs that can build up in a dusty corner of the lab. Good news – 2B Scientific recycle ice packs.

One step further

The above examples are some easy-to-follow tips – there are many more things that can be done to make your lab greener. For example, you can talk to companies about their sustainability policies, challenge them on their plastics, and feedback about their packaging. You can also liaise with your waste contractor to find out how they feel about recycling. Check My Green Lab and LEAF for bigger-scope ideas to improve your lab sustainability.

Take away messages

  • It’s ok to start small
  • If you are new – don’t be afraid to ask questions and make suggestions
  • Go for ‘easy wins’
  • Switch suppliers to support greener companies (e.g. we switched to New England Biolabs for our DNA purification kits and 2B Scientific for protein expression kits)

Don’t worry if you can’t do much – lab culture can be hard to change, and you may not have much control over how things are done in your lab. But every step helps – try something, and your example may encourage other people to take greener steps too!

A big thanks to LEAF and the King’s Chemistry sustainability team for the inspiration and ideas to make our lab greener.
