Nylon has two primary ingredients: diamine, which comes from crude oil, and adipic acid. Like many widely used synthetic ...

The two companies started their collaboration last year with Lululemon funding ZymoChem's development of a bio-based alternative to adipic acid, a petroleum-derived key ingredient in nylon 6,6.

That partnership involved an investment to create a bio-based version of adipic acid, which is traditionally made from petroleum, and is a key component used in developing nylon 6,6, per the release.

The company says it is pursuing recertification at two of its sites while seeking new certification in two others.
