# Kintra Fibers

> Kintra Fibers is a Brooklyn-based materials science company developing a bio-based, biodegradable alternative to conventional polyester. Built on polybutylene succinate (PBS) derived from plant sugars rather than fossil fuels, Kintra's yarn performs like standard polyester and runs on existing melt-spinning equipment, but composts in controlled conditions and sheds far less persistent microplastic. Founded in 2018 by Billy McCall and Alissa Baier-Lentz, the H&M Group-backed company has raised roughly $10M total and is piloting its fiber with brands including Inditex, BESTSELLER, Reformation and PANGAIA.
