About PreZero Polymers
PreZero Polymers is the recyclate specialist of the PreZero group and part of the Schwarz group. The company offers high-quality post-consumer (PCR) and post-industrial recyclates (PIR) as well as custom compounds in standard and specialty grades for industrial applications. Through a European post-consumer network with a processing capacity of more than 150,000 tonnes of recyclates per year, plastic waste is collected, sorted and processed in mechanical recycling processes into testable secondary raw materials, including at the HDPE plastics recycling plant in Grünstadt. The recyclates are externally certified according to RecyClass, with seamless traceability and auditable batch documentation, among other things to support customers' PPWR compliance. Sectors served include rigid industrial packaging, automotive, construction, rigid packaging & consumer, garden & agriculture, household as well as power tools and equipment. In addition, PreZero offers services such as the dual system PreZero Dual, packaging optimization (PreZero SPOT), circular economy consulting and the resale of surplus stock (ReValue).
