Toray Industries develops 100% bio-based adipic acid

In Japan, Toray Industries announced that it has developed what it claims to be the world’s first 100% bio-based adipic acid, a raw material for nylon 66 , from sugars derived from inedible biomass. 

The company noted that this achievement came from using a proprietary synthesis technique combining the firm’s microbial fermentation technology and chemical purification technology that harnesses separation membranes. 

Toray Industries said it will test polymerization of nylon 66, develop production technology, conduct market research, and take steps to commercialize applications for this bio-based adipic acid by around 2030. The firm highlighted that Nylon 66 has been used for many years in fibers, resins, and other applications due to its exceptionally durable, strong, and rigid properties. 

“Toray is developing a process for producing sugars from crop residues and other inedible plant resources. Sugars from this process could be used as raw materials for bio-based adipic acid. Toray would thus be able to create a total supply chain to make chemicals from inedible biomass, helping pave the way to a circular economy,” the firm said in a statement.
