Mitsubishi Chemical said it recently signed a licensing agreement with Mitsui Chemicals for Mitsubishi’s patent for biomass-based polyester. The agreement enables Mitsui to manufacture and sell polyethylene terephthalate (PET) made from biomass. Mitsui will consider producing bio-PET at its Iwakuni Otake petrochemical complex in Japan by using bio-MEG. Mitsubishi’s patent is registered in Japan, the U.S., the European Union and China.
