In Japan, Toray Industries, Inc., has recently signed a memorandum of understanding with major Thai petrochemicals producer PTT Global Chemical Public Company Limited (GC) to explore mass production technology for adipic acid made from non-edible biomass.
Toray and GC will jointly evaluate the feasibility of mass production technology and commercialization in Thailand and Japan. If business is determined viable, they aim to commercially manufacture several thousand metric tons of bio-based muconic and bio-based adipic acid annually by 2030.
Last year, both companies began jointly developing technology to produce these raw materials for nylon-6,6 from non-edible biomass-derived sugars made at Cellulosic Biomass Technology Co., Ltd., a Thai company in which Toray has an 84% stake.
GC employs its proprietary fermentation technology to quickly convert non-edible sugars into high yields of muconic acid. Toray uses its hydrogenation process to produce high yields of high-purity bio-adipic acid from muconic acid. The resulting bio-based adipic acid can serve as a raw material for nylon-6,6 for resins and fibers similar to the petroleum-derived nylon-6,6. On top of that, the manufacturing process does not generate nitrous oxide, a greenhouse gas by-product typically associated with chemical synthesis-based processes.
