Pyran has developed a process to manufacture 1,5-pentanediol (1,5-PDO), a key chemical used to make paints and plastics. Pyran’s patented process uses renewable wood and crop waste resources to make 1,5-PDO at less than 50% of the costs of competing oil-based processes. Pyran’s technology was developed at the University of Wisconsin-Madison and has been validated by both the U.S. Department of Energy and a large chemical company.
