As a link between academic research and industrial technology development, our vision is to develop and demonstrate sustainable and circular biorefinery processes and technologies for producing green gases, green liquid fuels, and green products, all of which will support the transition to a climate-neutral, zero-fossil-carbon economy. Consequently, the resource basis will be extended to include organic residues, wastes, and carbon dioxide. Conversion technologies will be enhanced or redesigned to ensure their efficient and economical operation, and to allow the value cycles based on new feedstocks to be integrated into the system. By using our excellent experimental facilities, ranging from lab to pilot and demonstration scale plants, our goal is to conduct applied research of the highest scientific quality. We apply advanced digital methods for technology development, and for the basic automation, optimization, and monitoring of the operation of individual technologies and entire plants. With the help of holistic and technology-neutral planning tools, we ensure that biorefineries and energy supply technologies are optimally integrated into a sustainable, renewable energy system.
