Sustainable Chemicals, LLC

Sustainable Chemicals, LLC, operating as Sust-Chem™, is a materials science company based in Golden, Colorado, that develops plant-based bioplastics designed to serve as direct, cost-competitive replacements for conventional petroleum-based polyolefins like polyethylene and polypropylene. The company utilizes a proprietary, high-yield, non-fermentation chemical process to convert cellulosic biomass into its patented, next-generation biopolymer known as Replose™. Unlike traditional bioplastics that often face limitations in performance and cost, this material is engineered for both rigid and flexible applications while maintaining mechanical properties that match or exceed those of conventional fossil-fuel plastics. The technology also features a benign end-of-life profile, as the material is chemically recyclable and designed to naturally degrade into harmless, non-persistent molecules if dispersed into the environment. By bypassing the need for complex fermentation, the company aims to scale production economically to address the global plastic pollution crisis and reduce carbon emissions. Supported by non-dilutive funding, including multiple SBIR grants from the USDA, the firm is working to transition its technology from development to commercial-scale deployment. Its solutions are intended to assist the plastics industry in meeting sustainability goals by providing a scalable, drop-in alternative that mitigates reliance on finite petrochemical feedstocks and helps decrease the accumulation of microplastics.
