Carbios' new factory will use enzymes to biorecycle plastic:

In a matter of hours, the enzymes decompose the plastic into the material’s basic building blocks, called monomers, which can then be separated, purified, and used to make new plastic that’s identical to virgin material. Later this year, the company will begin construction on its first demonstration recycling plant.

This sort of innovation could change the whole debate about plastics. Exciting stuff, if it works.
