Sustainability has been the central theme at the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut WKI since its foundation in 1946. Founder and eponym Dr. Wilhelm Klauditz Dr. Wilhelm Klauditz sought solutions for the optimal exploitation of raw wood – a commodity which had become scarce as a result of the war - as well as for the technical utilization of waste wood and small-dimensioned wood. He is considered a pioneer of the modern wood-based materials industry. Today, the Fraunhofer WKI utilizes the entire spectrum of renewable raw resources in order to develop sustainable materials, components and chemical products. A particular focus is on the use of plant residues and waste materials.

The institute, with locations in Braunschweig, Hanover and Wolfsburg, specializes in process engineering, molding and component production with biomaterials, bio-based binders and coatings, functionalization, fire protection, material and product testing, recycling processes and the utilization of renewable raw materials in buildings and vehicles. A particular focus is on sustainable lightweight construction solutions.  Furthermore, the Fraunhofer WKI is one of the leading research institutions in the field of indoor air quality.

Virtually all the processes and products resulting from the institute’s research activities are used in industry. The Fraunhofer WKI's customers include companies from the wood and agricultural industries, the chemical industry, the construction and furniture industry, the automotive industry and the packaging industry. 

Through its research and development activities, the Fraunhofer WKI provides an important contribution towards the development of a bio-based circular economy (circular bioeconomy).
