Based on the provided excerpt: Toray Industries and PTT Global Chemical have developed a first-of-its-kind process to produce bio-based adipic acid by fermenting bio-muconic acid derived from starch residues, enabling the manufacture of 100% bio-based nylon 66 from waste biomass. The pathway points toward waste-based nylon materials and reduces reliance on fossil-derived inputs.

Question: What markets or products do you think are best positioned to adopt 100% bio-based nylon 66 first, and what scale-up or supply-chain hurdles might slow broader adoption?

Novel bio-based adipic acid pathway leads the way to waste-based nylon materials

Toray Industries, Inc. (Tokyo) and PTT Global Chemical PLC (PTTGC; Bangkok, Thailand) have established a first-of-a-kind series of manufacturing technologies for bio-based adipic acid (the main raw material of nylon 66) through the fermentation of bio-muconic acid using starch residues, ultimately producing 100% bio-based nylon 66 using it. As there is a global demand to […]

If the adipic acid is truly drop-in, the polymer should be the same, but the devil is in trace impurities and stabilizer packages. Before I swap to bio PA66 for cable ties and housings around hot hydrocarbons, I want ASTM D471 immersion in diesel or condensate including sour, moisture uptake and creep, and UV or thermal aging data. Also, is your HMDA bio-based too?
