Depolymerization

Reaction Mechanism

Heat and chemical agents sever the covalent bonds that hold the polymer backbone together. Efficient depolymerization requires controlled pressure and specific catalysts to maximize the yield of usable monomers. Contaminants in the waste stream can poison the catalyst and reduce the conversion rate.

Feedstock Recovery

Purified monomers from the reactor enter the standard polymerization process as if they were derived from crude oil. Because depolymerization removes dyes and additives at the molecular level, the resulting resin avoids the graying and loss of properties seen in mechanical recycling. This allows for an infinite loop of reuse without the degradation of mechanical strength.

Moulders can treat these materials as virgin resin in demanding thin-wall applications. The technology supports the production of food-grade packaging from post-consumer waste that would otherwise be downcycled.

Process Limit

High energy requirements often make the technology more expensive than traditional landfilling or mechanical shredding. Successful depolymerization depends on a clean and consistent waste supply.
