Going ALL IN

Recycled materials from Interzero already cover a wide range of products and many other use cases are still possible. The recyclable materials from domestic yellow bins are being used to make new plant pots, paint tubs, baskets and crates for logistics, for example. Even parts for sustainable biogas plants are now based on recycled plastics from Interzero: in Mönchengladbach, technoplast Kampes GmbH has developed an important plastic component for use in biological desulphurisation plants.

“Biogas production generates hydrogen sulphide, which needs to be removed in the biogas plant”, explains Dr Achim Kampes, Managing Director of this family-run business. The packing material used here consists of many cross-struts, whose surfaces are then colonised by specialised bacteria that can split hydrogen sulphide and separate it from the biogas. Kampes: “If I want to make a part like this using injection moulding, I need a homogeneous material with good flow properties. Interzero supplies us with a polypropylene recyclate that is highly uniform. Material properties are extremely consistent and, as another huge advantage, the plastic has virtually no odour.”
