Hello again. Today I’d like to continue our series about how to be eco-friendly in a laboratory. Remember last weeks post about the initiative at the Simon Fraser University? Here’s another university promoting green laboratories: the University of Washington. Besides the Green Office, Green Greek (“acknowledges and educates Greek community members about their habits at home relating to sustainability”) and “SEED Green Endorsement” (recognising UW students living on campus and off, who are thoughtful about the impact of their daily life on the environment), it has the Green Laboratory Program, which I’ll introduce here now in more detail, i.e. especially the Freezer Challenge.
As pointed out on their website, “Laboratories are one of the main generators of waste …”. So true. Working in a molecular biology lab, I’v thrown away a lot of consumables every day – all the reaction vials called Eppis, all the disposable pipette tips, transfer pipets, micro plates, … – it’s simply the way, it’s the way they are supposed to be used: just once. And then you throw them away.
But leaving this aspect aside for the moment (more about this in a later post), there’s another factor with a huge impact on the environment: the energy consumption of a laboratory. I didn’t know that a lab is “using about 4 times more energy than an office of the same size”. Wow. But giving it some thought, I absolutely believe it because there’s a lot of equipment running from morning to evening or even 24h. Of course, some equipment has to run permanently, such as the various incubators, fridges and freezers. After all, your freezer at home also runs 24/7, doesn’t it? But – and here’s an important difference – your freezer at home probably got a good Energy Star rating. Why? Let’s be honest: because it’s you who’s paying the electricity bill and getting one of those A+++ fridges is one one way to save money, isn’t it?
I know, we’re back talking about money and not just about saving the environment. My feeling is that you can’t avoid this connection – there’s simply a strong link between them. Anyway, why not use saving money as a strong motivation to be more eco friendly? In the laboratory, it’s the university who’s paying the bills. But if you care about it anyway and help them to reduce their energy bill:
a) you’ve done something good for the planet and
b) you might get more money for your research – at least, you’d very much hope, that’s where the saved money ends up.
