Japanese petrochemical producer Mitsubishi Chemical plans to demonstrate production of recycled polyethylene (PE) and polypropylene (PP) at its chemical recycling plant in eastern prefecture Ibaraki from this summer.
Mitsubishi Chemical and its five recycled plastic supply chain partners — the city of Kashima in Ibaraki, recycled material producer Refinverse, package manufacturer Toyo Seikan, food supplier Kewpie and Ibaraki-based supermarket operator Kasumi — signed an agreement on 14 February to collaborate in demonstrating recycled plastic production and supply. The firms will collect waste plastics within Ibaraki for processing to produce oil, which will be used to manufacture recycled plastics such as lids of sauce bottles for supply to the market before being collected from end users as waste plastics for chemical recycling.
Mitsubishi Chemical will use its chemical recycling plant in the Kashima petrochemical complex in Ibaraki for this circular economy project. The firm completed construction of the plant in November 2024 and has been conducting a trial run to turn waste plastics into regenerated oils. Mitsubishi Chemical's subsidiaries Japan Polyethylene and Japan Polypropylene will be in charge of manufacturing PE and PP from the recycled oil.
The demonstration will continue until June 2026. But the timeline for this project and its Kashima chemical recycling plant beyond this, including targets for commercial operations, was not disclosed.
Mitsubishi Chemical initially aimed to start commercial operation of the plant, which can process 20,000 t/yr waste plastics to generate around 12,000-16,000 t/yr of regenerated oil, by the April 2023-March 2024 fiscal year. But construction was postponed because of the Covid-19 pandemic and delays in deliveries of equipment amid the Ukraine-Russia conflict.
