Pyran has developed a renewable process to manufacture 1,5-pentanediol, a key chemical used to make paints and plastics. Pyran’s patented process uses renewable wood and crop waste resources to make 1,5-pentanediol at over 2x lower prices than competing oil-based products. Pyran’s technology was developed over the course of three years at University of Wisconsin-Madison under the supervision of Prof. George Huber as part of a $3.3 million US Department of Energy (DOE) grant. Pyran is currently the only company to make 1,5-pentanediol at our selling price and the only company to make renewable 1,5-pentanediol.
