Maybe I’m wrong, but I tend to think that people are attracted to biological research because of an interest in nature and the noble desire to make the world a better place.
Those ideals are often stripped away in the realities and demands of working life – it turns out that it’s not so easy for one person to save the world, and you have to be more interested in Nature than nature to be successful. But I’ve always found it a bit paradoxical that from those eco-aware origins, we end up working in labs that generate vast amounts of waste and consume a lot of power.
Of course, much of this waste and consumption is unavoidable but there are a lot of ways that we can reduce the environmental impact of our labs by improving our practices. Here are 12 ways to start with:
1. Hold completed overnight PCR reactions at 10°C instead of 4°C. It won’t affect the product, but it will save a considerable amount of energy.
2. Replace falcon tubes with re-usable 50mL glass bottles in experiments that don’t require you to centrifuge the contents.
3. Close or switch off the fume hood. Fume hoods use vast amounts of power and the amount they consume is proportional to how far they are opened.
4. Buy reagents from on-site stores / freezer programs where possible. Does your BamHI really need to be chauffeur driven to you? On-site stores transports reagents in bulk, which saves fuel.
6. Buy service contracts for your equipment. That shiny new HPLC/spec/PCR machine looks great but 10 years down the road it’s going to be land-fill fodder if it’s not looked after. An annual service contract will prolong the life of your equipment, reducing waste, and keep your lab ticking over more reliably.
Problems with expressing your gene? One of the potential stumbling blocks in heterologous gene expression is incompatible codon usage. Every amino acid can be encoded by more than one codon, and for every amino acid each organism has a favorite codon that it tends to use more often than the others. The availability of tRNA […]
