DePoly SA is a Swiss cleantech company developing chemical recycling technology for PET and polyester plastics. Its process converts unsorted, contaminated PET waste back into PTA and MEG - key chemical precursors used to manufacture new plastics - without the need for pre-washing, pre-sorting, pre-melting, or separating out other plastics.
The company's approach addresses a significant gap in plastics recycling. Conventional mechanical recycling typically requires clean, sorted inputs and degrades material quality with each cycle. DePoly's chemical process can handle dirty, mixed waste streams and produce virgin-grade raw materials, enabling genuinely circular use of PET without reliance on fossil-derived inputs.
Operating from Switzerland, DePoly works at the intersection of chemical manufacturing, cleantech, and waste conversion. Its technology targets one of the world's most widely used plastics - PET is found in bottles, packaging, and polyester textiles - offering a pathway to reduce both plastic pollution and the petrochemical feedstocks that underpin new plastic production.
