Mitsui Chemicals and Teijin to develop biomass-derived BPA, polycarbonate
Partnership will support efforts to achieve carbon neutrality by reducing greenhouse gas (GHG) emissions throughout product lifecycles
Mitsui Chemicals, Inc.and Teijin Ltd. jointly announced that they will become Japan’s first companies to develop and market biomass-derived bisphenol A (BPA) and polycarbonate (PC) resins, that will support efforts to achieve carbon neutrality by reducing greenhouse gas (GHG) emissions throughout product lifecycles.
The joint initiative follows Mitsui Chemicals’ receipt of ISCC PLUS certification from the International Sustainability and Carbon Certification (ISCC), based on which Mitsui Chemicals will begin supplying biomass BPA produced with the mass-balance approach. In the ISCC PLUS-certified mass-balance approach, materials are verifiably tracked through complex value chains, as in the case of biomass-derived raw materials being mixed with petroleum-derived raw materials to create products.
Teijin also will begin developing and producing biomass PC resin using the same BPA. In May 2022, Mitsui Chemicals acquired ISCC PLUS certification for BPA raw material used in PC resins. Mitsui Chemicals will now become the first Japanese company to produce commercial biomass-derived BPA offering the same physical characteristics as those of conventional petroleum-derived BPA.
Teijin will procure biomass-derived BPA from Mitsui Chemicals to produce biomass- derived PC resins possessing the same physical characteristics as the company’s existing petroleum-derived PC resins, which will allow these new biomass-derived versions to be used in commercial applications such as automotive headlamps and electronic components.
