You don’t need a PhD in biochemistry to build an ‘eco brick.’ Last year, the ‘eco-brick’ trend - which involves filling plastic bottles with non-recyclable plastic and sending them off to be used in construction - went viral on TikTok. Given that people use more than 37,000 tonnes of vanilin per year, it’s a significant breakthrough - and proves that recycled plastic could find new life on the industrial chemical market. Plastic bottles can be converted into vanilla flavouring using heated bacteria, a 2021 study reveals.īy adding E.coli to plastic, scientists could make vanillin, a compound found in vanilla beans. Scientists have successfully formed this gel into cups and plates - just maybe don’t think about where the crockery came from when you’re eating off it. The researchers isolated two short strands of DNA from the sperm, binding them together with a chemical from vegetable oil.įrom here the gel was moulded into different shapes and freeze-dried to remove the moisture, which makes it solidify. It might sound slightly fishy, but Chinese scientists have constructed an eco-friendly plastic from salmon sperm.
