Equipment BioCat, Straubing site

We are your partner for the development of the sustainable synthesis processes and the innovative chemical products of the future. We focus on the selection of biobased resources, the development of modern conversion and production processes and particularly on the application of catalytic processes (chemo-, bio- and electro-catalysis). This includes the analytical and functional evaluation of these processes and products. Following that idea, our goal is the production of new products and materials derived from renewables, residual streams, and carbon dioxide (CO2) in an environmentally benign manner – together with our partners.
