Scientists Use Bacteria To Turn Plastic Waste Into Paracetamol

Bacteria can be used to turn plastic waste into painkillers, researchers have found, opening up the possibility of a more sustainable process for producing the drugs. From a report: Chemists have discovered E coli can be used to create paracetamol, also known as acetaminophen, from a material produced in the laboratory from plastic bottles. 'People don't realise that paracetamol comes from oil currently,' said Prof Stephen Wallace, the lead author of the research from the University of Edinburgh. 'What this technology shows is that by merging chemistry and biology in this way for the first time, we can make paracetamol more sustainably and clean up plastic waste from the environment at the same time.'

Writing in the journal Nature Chemistry, Wallace and colleagues report how they discovered that a type of chemical reaction called a Lossen rearrangement, a process that has never been seen in nature, was biocompatible. In other words, it could be carried out in the presence of living cells without harming them. The team made their discovery when they took polyethylene terephthalate (PET) -- a type of plastic often found in food packaging and bottles -- and, using sustainable chemical methods, converted it into a new material.
