    Scientists develop infinitely recyclable plastic material

    20/08/2019· PDK presents an exciting breakthrough because it can be broken down at the molecular level and recycled into virgin-quality polymer without any loss of quality. Scientifically, it can be “depolymerized into its individual monomers and then remade,” explains Rachel O’Reilly from the University of Birmingham, UK. This allows it to be “upcycled” back into itself quite easily
