97 Dr. Michael Hofer Phone +49 9421 187-354 michael.hofer@igb.fraunhofer.de Prof. Dr. Volker Sieber Phone +49 9421 187-301 volker.sieber@igb.fraunhofer.de Outlook New polyfunctional bio-derived molecules from waste streams are interesting as a replacement for existing products obtained from fossil resources but also for the development of new materials. Our aim is therefore to develop more chemo- enzymatic processes for the production of new molecules. The first processes are already upscaled for the production of larger quantities of these molecules, which are then used for application tests by our customers. At the same time we are working on solutions for the simultaneous application of chemo- and biocatalysts in a one-pot reaction. 1 Cellulose production. 2 Combined chemo-enzymatic catalysis based on the example of camphor. 3 Batch reactor for the conversion of diketocamphene.
