Plastic to Plastic(PTP)

Under highly selective catalytic pyrolysis of olefins and reformation, COMY converts waste plastics into new plastic monomers and new plastics(also referred to as COMY Monomers).


COMY leverages its proprietary catalyst to efficiently convert mixed waste plastics into propylene. The process also generates by-products like BTX and liquefied substances, all derived from waste plastics and certified at GRS level. The PTP technology has multiple outstanding advantages.

PTP enables the full closed-loop chain-waste plastic to pyrolysis oil to new plastic-within a single facility. All products come entirely from waste plastic, with no fuel oil produced, achieving true "oil-free purification." This means every ton of waste plastic is maximally converted into high-value resins (e.g., polypropylene) instead of being diverted to fuel, with higher recycling efficiency than traditional methods.
