Pyran has developed a proprietary technology that enables the intentional production of 5-carbon molecules, specifically focusing on 1,5-pentanediol (1,5-PDO). This innovative approach allows Pyran to convert renewable agricultural products into 1,5-PDO, which is a sustainable alternative to traditional petroleum-based diols. The company’s process not only enhances the performance of the resulting polyols—improving their resistance to heat, water, oil, and weather—but also significantly reduces greenhouse gas emissions by over 95% compared to conventional methods. Pyran's 1,5-PDO has been certified as 100% biobased by the USDA BioPreferred® Program, underscoring its commitment to environmentally friendly practices.

In addition to its environmental benefits, Pyran's technology offers a cost-effective solution for industries reliant on 4- and 6-carbon diols. The 1,5-PDO produced through Pyran's process can directly substitute for existing petroleum-based chemicals, providing a viable alternative for applications in coatings, adhesives, and various consumer products. The company is actively exploring the expansion of its technology platform to develop additional 5-carbon products, aiming to enhance supply chains and meet the growing demand for sustainable chemical solutions across multiple sectors.
