Pyran announced recently the results of an independent cradle-to-gate life cycle assessment (LCA) for its 1,5-pentanediol (1,5 PDO).

According to a release, the study confirms that Pyran’s bio-based PDO reduces greenhouse gas (GHG) emissions by up to 99% compared to petroleum-derived 1,6-hexanediol.

“This third-party-validated life cycle assessment is a powerful endorsement of the science behind our technology and products,” Pyran Co-Founder and Chief Technology Officer Kevin Barnett said in a statement. “Achieving up to a 99% reduction in greenhouse gas emissions is not only a win for our customers’ efforts to improve the sustainability of their products, it’s a clear signal that renewable chemistry can deliver real impact without compromising performance or scalability.”

The study also revealed Pyran’s highly efficient, advantaged process technology delivered an 82% GHG reduction from improved process efficiencies alone, compared to existing petrochemical routes.

The company also earned the U.S. Department of Agriculture (USDA) Certified Biobased Product Label for its 1,5 PDO product.
