“This breakthrough shows how biomass-derived commodity chemicals can economically be used to replace petroleum-derived products,” says George Huber, Harvey D. Spangler Professor in chemical and biological engineering at UW-Madison and an affiliate of the Wisconsin Energy Institute.

Huber and his collaborators reported a new chemical pathway used to produce 1,5-pentanediol, a plastic precursor primarily used to make polyurethanes and polyester plastics. Their approach is six times cheaper than a previously reported method, and represents the first economically viable way of producing 1,5-pentanediol from biomass.

The discovery provides fundamental chemistry that could be applicable to a wide cross-section of products. For instance, the same pathway could be used to produce two other plastic precursors — 1,4 butanediol and 1,6-hexanediol — currently derived from petroleum and which together represent an annual market of  more than $6 billion.

The Wisconsin Alumni Research Foundation (WARF) is in charge of licensing the technology.

“We’ve had companies asking more about this exciting way to economically produce a valuable chemical from sustainable sources,” says Leigh Cagan, WARF’s chief technology commercialization officer. “Professor Huber’s published work will bring us closer to engaging with industrial partners to commercialize this technology.”
