LyondellBasell starts commercial production of polymers using raw material derived from plastic waste WESSELING, Germany, May 6, 2021 /PRNewswire/ -- LyondellBasell (NYSE: LYB) today announced another step towards its ambition to advance the circular economy by making virgin quality polymers from raw materials derived from plastic waste at its Wesseling, Germany, site. Produced by the thermal conversion of plastic waste, this raw material is converted into ethylene and propylene in the LyondellBasell production facilities, and then processed into polypropylene (PP) and polyethylene (PE) in the downstream units for plastics production. The first use of raw material derived from plastic waste follows the company's successful production of plastic materials made from renewable-based raw materials such as used cooking oil, which helps to reduce CO2 over the product life cycle and reduce the use of fossil-based raw materials.
