Led by Dr Amy Pickering and Dr Joana Alves, the lab changed single-use plastics with re-useable gear. The place alternate options weren’t accessible, the group decontaminated and re-used plastic gear which might have often been thrown away after one use. “We knew that we have been utilizing plastic day by day in our analysis, but it surely wasn’t till we took the time to quantify the waste that the volumes getting used actually hit residence. That basically emphasised the necessity for us to introduce plastic lowering measures,” mentioned Dr Pickering.
The lab developed a brand new scheme which centered on sustainability, shifting away from the usage of single-use plastics wherever doable. In some circumstances, the analysis group would use reusable picket or metallic objects as an alternative of plastic. If there have been no alternate options, the group centered on reusing plastic gear by chemically decontaminating the plastic tubes earlier than a second stage of decontamination below warmth and strain – generally known as autoclaving.
To find out the success of the scheme, the lab of seven researchers spent 4 weeks documenting the plastic waste produced in common circumstances. They then measured the quantity of waste produced over the subsequent seven weeks with new processes to scale back the consumption of single-use plastic. “As soon as the measures have been in place it was rapidly clear that enormous impacts have been being seen. Essentially the most shocking factor for us was how resilient some plastics are to being autoclaved and subsequently what number of instances they are often re-used. Which means that we have been in a position to save extra plastic than we initially anticipated,” mentioned Dr Pickering. In implementing these exchange and reuse practises, 1670 tubes and 1300 loops have been saved throughout a four-week interval. This led to a 43-kilogram discount in waste.
The standard microbiology laboratory makes use of principally disposable plastic, which is usually not recycled resulting from organic contamination. In 2014, 5.5 million tonnes of plastic waste have been generated in analysis laboratories worldwide. The Edinburgh lab works with harmful disease-causing micro organism, because of the risks of contamination, their waste have to be autoclaved and incinerated at a excessive environmental and financial price.
Practices to scale back plastic waste in analysis labs is turning into more and more common within the UK, with researchers from the College of York decontaminating and re-using plastic flasks and researchers from a chemistry lab in Edinburgh recycling 1 million plastic gloves in 2019. “It is vital to take a while figuring out what plastic objects you’re utilizing essentially the most. This can will let you determine each the simple wins, corresponding to changing plastic inoculation loops for re-useable metallic ones, in addition to the larger duties, corresponding to re-using plastic tubes. That may aid you to convey others on board and construct momentum,” mentioned Dr Pickering.
The brand new protocols not solely forestall plastic waste, but in addition lower your expenses in line with Dr Pickering: “Over a 3-month interval of implementing the protocols we can have saved over £400 of plastic tubes, inoculation loops, and cuvettes” she mentioned.
