Green adhesives made from whey
After the molasses are fermented in the bioreactor, the resulting gas-vapor mixture is passed through a mem-brane module and the valuable ethyl acetate is separated.

In collaboration with TU Dresden, Fraunhofer researchers have developed a process for obtaining valuable, high-purity ethyl acetate from whey. This can be used, for example, to produce environmentally friendly adhesives, thereby replacing conventional ethyl acetate extracted from fossil-based raw materials. It also eliminates the need for costly disposal of the molasses produced during whey processing.
