From frying oil to coupling relays
Bio-based plastic from bio-waste: Siemens and Envalior collaborate on more sustainable electrical products

Siemens Smart Infrastructure has launched a new series of coupling relays, with housing made from plastic that consists of 70 percent bio-based material - derived from biomass waste. The Akulon® K225-KS B-MB plastic was developed by Envalior, a world leader in a wide range of industries by designing and developing high-quality sustainable solutions, in collaboration with Siemens to ensure all the desired properties are met. The plastic’s raw material comes from used cooking oil (UCO), left over after frying in the food industry, restaurants, snack bars and households. As UCO is no longer suitable for human or animal consumption, it does not compete with food or animal feed production. While UCO is mainly used for biodiesel, Envalior uses it for the production of engineering plastics based on a mass balance concept, avoiding incineration.
Process steps – from more sustainable raw material to finished coupling relays

“Collaborating with Envalior to create this bio-based plastic is an important step towards advancing the use of more sustainable materials in our electrical products. We are pleased to work with Envalior as another strong partner on our journey towards a more environmentally friendly portfolio,” says Andreas Matthé, CEO of Electrical Products at Siemens Smart Infrastructure.
“At Envalior, we are proud to have partnered with Siemens in the development of the SIRIUS 3RQ4 coupling relay series. A key success factor in this project was achieving excellent flow behavior in thin-wall designs and a UL94 V-0 rating at just 0.4 mm thickness, while simultaneously achieving an outstanding green share from bio-waste sources but at prime quality,” says Dr. Marc Rudolf, Global Key Account Manager, Envalior.
