matterr is a recycling technology company focused on closing the loop for polyester (PET). The company develops chemical depolymerization processes that convert polyester-rich waste, including blended textiles and multilayer packaging, back into base monomers such as terephthalic acid (TPA) and ethylene glycol (EG).
By supplying purified, virgin-equivalent monomers that can be reintroduced into existing polyester production assets, matterr targets hard-to-recycle streams, reduces reliance on fossil feedstocks, and supports a circular value chain for packaging and textiles. Its activities include process development, industrial deployment with partners, and technology licensing to scale circular PET production.
