Plastic household waste contains all sorts of contaminants that make it unsuitable for the mechanical recycling of PET. Think of meat dishes, food packaging and synthetic textiles. This leads to increasingly larger polyester flows that can not simply be recycled mechanically due to food legislation. Chemical recycling is the solution.

In chemical recycling, the plastic falls apart into the separate chemical building blocks. Impurities and dyes are therefore easy to remove. This is impossible with mechanical recycling.

Cumapol from Emmen, together with Green PAC and the University of Groningen, developed a new process and will soon start construction of a pilot plant. Cumapol wants to use bioglycol from Avantium in Delfzijl to make the end result as sustainable as possible.

Recently it became known that Coca Cola becomes a partner of the DEMETO project, in which chemical recycling process takes place with the aid of microwaves. According to Marco Brons, technical director of Cumapol, the PET flows of deposit bottles are of such quality that effective mechanical recycling is possible.
