The company specializes in chemical polyester recycling, aiming to make polyester an infinite resource by converting waste into virgin-quality raw materials. matterr develops innovative depolymerisation technology that recycles mixed PET waste streams, including blended polyester textiles and multilayer packaging, into their original molecular building blocks, terephthalic acid (TPA) and ethylene glycol (EG). The company operates using alkaline hydrolysis, achieving recovery rates above 95% under mild conditions. matterr provides industrial-grade chemical raw materials and technology licensing, focusing on the packaging and textile industries. It partners with major brands, including BESTSELLER, to supply high-quality recycled raw materials. matterr is constructing its first small-scale industrial plant in Hürth, with a planned capacity of approximately 10,000 tonnes of polyester-rich waste annually, supported by strategic investors and EU funding.
