Summary
The R & D collaboration with Brazilian partners aims at resource-saving processes and at the production of bio-based materials for a sustainable bio-economy. The aim is to develop environmentally friendly processes for the utilization of agro-industrial wastes and by-products such as lignocellulosic residues of sugar cane industry. Research in the project focuses on methods to make carbohydrates (sugars) available for subsequent fermentation. Experimental work is carried out both in Brazil and in Germany. Tasks include enzymatic pretreatment, provision of sugars and laboratory tests for lactic acid fermentation in Brazil, and the parallel testing of bacteria already proven for other substrates as well as a scale-up of processes to pilot scale in Germany. Results will indicate whether the used plant raw materials are suitable for the subsequent implementation of biotechnology to non-food products such as bioplastics. The results should help to accelerate the development of knowledge-based bio-industries and to significantly enhance the use of renewable raw materials in the chemical industry.
