On March 6, 2025, Sumitomo Chemical announced that it will start selling its polymer material, polymethyl methacrylate (PMMA), which is made from methyl methacrylate (MMA) monomers produced through chemical recycling. South Korea's LG Display and Japan's Nissan Motor have decided to use this chemically recycled material in their products. As an industry leader, Sumitomo Chemical will accelerate the implementation of chemical recycling in the MMA supply chain. In 2022, Sumitomo Chemical built a new PMMA chemical recycling pilot facility at its factory in Niihama City, Ehime Prefecture, Japan. It also implemented a joint project with Niihama City to recycle PMMA protective partitions used to reduce droplet spread, and provided chemically recycled PMMA to Star Jewelry as raw material for jewelry. In addition, Sumitomo Chemical has obtained third-party certifications such as ISCC PLUS and is making efforts to implement practical recycling systems worldwide using the mass balance approach. Sumitomo Chemical will supply chemically recycled PMMA produced in its large-scale production facilities for high-quality applications such as electronics and automobiles. The company will start selling the product to LG Display as raw material for the light guide plates used in liquid crystal display backlights and to Nissan Motor as raw material for the lenses used in automotive headlights. Sumitomo Chemical is making significant adjustments to its petrochemical-related business, creating value through technologies that reduce environmental impact. The value of recycled materials and products is increasingly recognized. To keep pace with this progress, Sumitomo Chemical will expand its chemical recycling MMA material business and provide products widely throughout society through technology licensing, contributing to the realization of a sustainable society.
