Greener polyurethanes start with plant-based raw materials.

A shift to a bio-based raw material can reduce several chemical hazards associated with making one of the most popular plastics – polyurethanes – in production today, researchers report in the journal Green Chemistry. The new process means polyurethane plastic may be less hazardous to make and easier to break down in the environment.
Polyurethanes are a family of commodity plastics very commonly encountered in everyday life. They are widely used in industrial, automotive, engineering and medical applications and are found in a large range of products, including paints, foams, adhesives and coatings.
The new process for making polyurethanes focuses on one class called polycarbonate urethanes. These are found commercially in coatings and medical devices.
