Oleon, a Belgian company, announced on June 28 that it had put into operation a biogas propylene glycol plant with an annual capacity of 20,000 tons in Ertvelde. This project, with an investment of 8.2 million euros (about 10.2 million U.S. dollars), uses glycerol as a raw material to produce propylene glycol, which can reduce carbon dioxide emissions by 70% compared with the propylene-based route.
The project uses BASF-developed technology and has fewer production steps compared to the traditional hydrolysis process. BASF also supplies it with catalysts used in production.
