Pyran, Inc. announced results from an independent life cycle assessment (LCA) confirming that its bio-based 1,5-pentanediol (1,5 PDO) delivers up to a 99% reduction in greenhouse gas emissions compared to petroleum-derived 1,6-hexanediol.

The cradle-to-gate LCA was conducted by a third-party firm and validated by an expert review panel, with full alignment to ISO 14040, 14044 and 14067 standards. The analysis also showed an 82% reduction in GHG emissions from process efficiency gains alone, as well as advantages across multiple environmental impact categories.

“This third-party-validated life cycle assessment is a powerful endorsement of the science behind our technology,” said Kevin Barnett, Pyran co-founder and chief technology officer. “It proves that renewable chemistry can deliver real impact without compromising performance or scalability.”

The announcement follows Pyran’s recent USDA Certified Biobased Product Label for 1,5 PDO, verifying that the material is 100% biobased. Pyran uses intermediates from non-food, renewable feedstocks—such as corn cobs and sugarcane bagasse—to produce 1,5 PDO, a performance-enhancing material for coatings, adhesives and other applications.

The company has completed front-end engineering design for commercial-scale production, finalized site selection for a U.S.-based facility, and achieved REACh registration for the European market.
