Covestro reaches new chemical recycling milestone

Covestro has developed an innovative process for recycling polycarbonate, i.e. polychain plastics. In this process, plastics are converted back into their monomers, a precursor of plastics, so that they can be fed back into the production process as alternative raw materials. At Covestro in Leverkusen, the technical implementation of chemical recycling is now beginning on a pilot scale. On the way to industrial scale, the process is still being optimized and is undergoing further development stages.

The newly developed process, which was driven by an international team, is a specific chemolysis process adapted to polycarbonate.

Following successful development in the laboratory, the next stage of development, the technical implementation of a continuous process, has already started. A pilot plant, which is currently in the planning stage, will be used to gather the experience needed for further expansion to industrial scale. Millions of euros will be invested in this over the next few years. The pilot plant will be built in Leverkusen, Germany.
