The South Korean conglomerate SK Group is investing $123 million in TBM, a Japanese start-up developing Limex, a flexible and moldable composite based on calcium carbonate. The two firms will collaborate on a biodegradable form of Limex made by adding SK’s polybutylene adipate terephthalate (PBAT). Inexpensive calcium carbonate should make the Limex-PBAT combination cost competitive with other biodegradable plastics, the firms say. TBM says 6,000 companies and local governments in Japan already use Limex instead of plastics and paper.
