Cardiff University
A new method for recycling coloured plastics has been developed by scientists at Cardiff University.
The process, which breaks down coloured polymers, the principal component of plastics, into their original components, could lead to a circular plastic recycling economy reducing pollution on land and in our oceans, the researchers claim.
Widely used in drinks bottles, food packaging, clothing and electronics, coloured plastics can be melted down and remoulded into new products, but additives or colourants cannot be removed in current recycling processes.
To avoid this method of downcycling, where recycled plastic is of lower quality than the original material, the Cardiff team used a chemical process called depolymerisation.
