Towards sustainable science, a discussion with My Green Lab®

To celebrate Earth Day during the month of April, INet-NYC has decided to partner up with My Green Lab® to raise awareness about energy consumption in our labs and to work together towards a more sustainable approach of science. My Green Lab®  is a US based non profit organization that works with labs all over the world. Their goal is to bring awareness to the environmental impact of laboratory operations and share best practices to make changes that lead to science sustainability.
Together with our guest speaker Christina Greever, Sustainability Program Manager at My Green Lab®, Dr Marta Collu and myself hosted a webinar about laboratory sustainability and Green Labs movements you can watch or rewatch on our YouTube channel.

Reducing the environmental impact of research has not only interested researchers in the NYC area or the US, but also around the globe. We were very pleased to count among our attendees, scientists from Australia, Canada, Colombia, India and the UK!

When we think about waste in a lab environment we tend to only think about single use plastic consumables and packaging, and forget about the energy consumption and the amount of water used in our lab processes. Therefore, Christina walked us through the impact of our research, using very specific and striking examples. Did you know that one Ultra Low Temperature (ULT) Freezer consumes as much energy as one average US household per year? And chilling it up to -70°C instead of -80°C can save as much as 30% of the consumed energy.

*Laboratories discard 2% of the global plastic consumption*

According to Christina, Science is one of the final frontier of sustainability, because every lab is as complex as the research that is conducted. But sustainability can be reached in scientific processes in a lot of different ways. We do know that science is very resource intensive, then how can we combat this excess resource use?

There are more and more institutions-based green lab programs growing around the world.
There is interest and leadership towards sustainability coming not only from universities but also from industry and companies that are committing to greening their manufacturing processes.

“You are not alone in caring about reducing the environmental impact of science”

A few easy steps to get started:

• Identify your largest waste streams. You might think it's gloves or pipette tips, but it actually could be something else depending on your usage.
• Take advantage of vendor take-back recycling programs, for example New England Biolabs®  and Sigma-Aldrich® participate in these kinds of programs.
• Prevent over-purchasing by sharing supplies and common reagents.
• Consolidate orders from the same vendors.
  

We can also reduce waste with green chemistry, and your lab doesn’t have to be a chemistry lab to follow the 12 principles of green chemistry!
Beyond Benign is an organization that focuses on these lab practices. “Green chemistry is the design of chemical products and processes that reduce and/or eliminate the use or generation of hazardous substances. This approach requires an open and interdisciplinary view of material and product design, applying the principle that it is better to consider waste and hazard prevention options during the design and development phase, rather than disposing, treating and handling waste and hazardous chemicals after a process or material has been developed.”

When we are at home, turning off lights after leaving a room or running dishwashers when they are full seem like a non-brainer. The simplest actions can have a big impact on the environmental cost of a lab in terms of energy consumption, because they have a much bigger impact in our labs than we can imagine.

“If every lab turned off one piece of equipment over night, it could save the equivalent of taking over 10,000 cars off the road.”

Among the best practices Christina listed, she also gave the examples of shutting the chemical hood sash to save two average US households worth of energy, defrosting and removing ice for our cold storage for them to operate at maximum efficiency.

To support scientists in their quest towards best practices, Christina said that My Green Lab has launched different programs designed so that individuals, laboratories, institutions, suppliers can interact and engage together to transform how science is done around the world. 
Here are a few of them:

• My Green Lab certification

An affordable program that focuses on behavior change and on actions that scientists have influence over. Focusing on equipment purchases and consumables. My Green Lab provides insight into areas for improvement and feedback into changes implementation.

• Freezer Challenge

A free international program, running until July 1st, 2021 this year. Over the last 4 years, the combined effort of scientists participating in the Freezer Challenge have saved 9.9 million kWh.

• The ACT label

ACT (Accountability Consistency Transparency) labels are eco-nutrition labels for laboratory products such as consumables, lab equipment and chemicals.
Using this label, as scientists and purchasers, we can standardly compare and choose the most sustainable and eco-friendly products.

• My Green Lab Ambassadors

A free program designed for scientists and sustainability professionals. My Green Lab Ambassadors can brainstorm and engage together towards sustainable science and awareness in their institutions. It can also be a great networking opportunity.

In summary, the smallest changes in our daily work life can have a massive impact on our environmental cost.
