The Brett Helms Research Group, part of the California-based Lawrence Berkeley National Laboratory, has synthesised a new type of plastic polymer – poly(diketoenamine)s or PDKs – that can be completely recycled, even in the presence of additives like dyes, flame retardants and glass fibres. The discovery was published in Nature Chemistry in May 2019. Between 2010 and today – according to data from the Centre for Environmental Law – major oil companies have invested over 180 billion dollars in the construction of new infrastructure for the production of plastics, over 99% of which are obtained from fossil fuels. A good way to make the plastic recycling process more economically advantageous and logistically simpler is to create products that are easily recyclable at a l...
