An Infinitely Recyclable Plastic Could Solve the World's Pollution Problem
Scientists at the Lawrence Berkeley National Laboratory have developed a new infinitely recyclable plastic that could be the answer to the world’s growing pollution problem.
They’ve engineered microbes to make the ingredients for a sustainable alternative to the 90% of plastics that can’t currently be recycled, many of which use finite, polluting petrochemicals as the building blocks.
The California research team has successfully engineered microbes to make biological alternatives for the starting ingredients in an infinitely recyclable plastic known as poly(diketoenamine), or PDK.
“This is the first time that bioproducts have been integrated to make a PDK that is predominantly bio-based,” said project leader Dr Brett Helms.
“And it’s the first time that you see a bio-advantage over using petrochemicals, both with respect to the material’s properties and the cost of producing it at scale.”
He explained that, unlike traditional plastics, PDK can be repeatedly deconstructed into “pristine” building blocks and formed into new products with no loss in quality.
PDKs initially used building blocks derived from petrochemicals, but those ingredients can be redesigned and produced with microbes instead.
