Heraeus Holding GmbH invested substantial equity to take a majority stake in perPETual Technologies, a PET recycling company. To drive global expansion under one brand, Heraeus renamed the company revalyu Resources GmbH (revalyu).

Polyethylene terephthalate (PET) is the most common thermoplastic polymer of the polyester family. It is used in textiles, packaging containers for liquids and foods, thermoforming for manufacturing and many other consumer products.

According to Heraeus, Revalyu has developed an environmentally sustainable depolymerization technology to recycle post-consumer PET bottles into sustainable esters (monomers), which is the base chemical building block for anything polyester based. Revalyu’s polymer can be used to manufacture sustainable PET products.

The company currently produces filament yarns for the textile industry in its manufacturing facility in Nashik, India.
