Pyran, Inc. announced the results of an independent life cycle assessment (LCA) for its biobased 1,5-pentanediol (1,5 PDO). The ISO-standard assessment, reviewed by experts, found that Pyran’s 1,5 PDO can reduce greenhouse gas emissions by up to 99% compared to traditional petroleum-derived 1,6-hexanediol.
The study indicated that Pyran’s process technology alone achieved an 82% reduction in greenhouse gases due to improved efficiencies over conventional methods. The analysis also pointed to environmental benefits in resource consumption, particulate matter reduction, and overall climate impact, highlighting the product’s sustainability.
Pyran’s co-founder and CTO, Kevin Barnett, emphasized the significance of the third-party validation, noting its reinforcement of the scientific rigor behind their technology. He stated that this substantial GHG emission reduction demonstrates renewable chemistry’s potential for sustainable solutions without compromising performance or scalability.
The company has earned the USDA Certified Biobased Product Label for its 100% biobased 1,5 PDO under the USDA BioPreferred® Program. Pyran has also made progress toward commercial production, completing front-end engineering design (FEED) for a large-scale facility, selecting a U.S. production site, and registering its product under European REACh regulations. Having demonstrated its technology at a smaller scale, Pyran currently supplies 1,5 PDO to select customers via scaled toll production.
With $12.5 million in funding, Pyran is transitioning to commercial operations, aiming to serve industries like paints, coatings, and adhesives. The company uses non-food renewable feedstocks such as corn cobs, wood, and sugarcane bagasse for its 1,5 PDO, offering a substitute for often costly and supply-constrained petroleum-based chemicals. These advancements underscore Pyran’s commitment to providing sustainable, high-performance bio-based materials that meet the demand for environmentally sound and reliable chemical solutions.
