Lanxess: To Produce First Bio-based EPDM Rubber
Lanxess AG, Leverkusen, Germany, is strengthening its commitment to produce premium synthetic rubbers from bio-based raw materials. The German specialty chemicals company aims to commercially produce ethylene-propylene-diene monomer (EPDM) from bio-based ethylene by the end of the year. It will be the first form of bio-based EPDM rubber in the world.
EPDM is conventionally produced using the petroleum-based raw materials ethylene and propylene. Alternatively, Lanxess plans to use ethylene derived purely from the renewable resource sugar cane. This bio-based form of ethylene is produced by dehydrating ethanol from Brazilian sugar cane. The company Braskem S.A. will supply the bio-based ethylene via pipeline to Lanxess’ existing EPDM plant in Triunfo, Brazil.
Triunfo currently produces 40,000 metric tons per year of regular EPDM rubber and it is expected that the first batches of the product Keltan Eco will amount to several hundred metric tons. The company’s other EPDM production sites are based in Geleen, The Netherlands, Marl, Germany, and Orange, Texas, U.S. All EPDM grades will be sold in the future under the brand name Keltan.
