Fraunhofer Institute for Wood Research
Wilhelm-Klauditz-Institut WKI

The Fraunhofer WKI specializes in bio-based chemical products and materials, production technology, functional integration, lightweight construction, material and product testing, recycling processes and indoor air quality. Almost all processes, materials and products resulting from our research activities are used industrially. We operate worldwide and work project-related with research institutions and industrial partners, e. g. with companies from the wood and furniture industries, the construction industry, the chemical industry, the packaging industry and the automotive industry. Our particular strength is our holistic research approach. We develop materials and technologies for a bio-based, resource-conserving and climate-friendly economic cycle - from raw materials to development and quality assurance to recycling.

Press release / 15.3.2023

Sustainable textile-reinforced concrete

Textile-reinforced concrete components with a sustainable natural-fiber reinforcement possess sufficient bond and tensile load-bearing behavior for the utilization in construction. This has been verified by researchers at the Fraunhofer WKI in collaboration with project partners. In the future, textile-reinforced components with natural-fiber reinforcement could replace conventionally reinforced concrete components.

New office building

Researchers at the Fraunhofer WKI and the Fraunhofer IAP, in collaboration with industrial partners, have achieved initial success in the development of bio-based flame retardants in bioplastics. In the future, it could therefore be possible to utilize plastics in electronics and electrical engineering that consist of 100 percent bio-based materials.


Press note / 12.1.2023

International Green Week

The Fraunhofer WKI will show four-meter-long sections of a wooden crash-barrier for road construction at the International Green Week, which takes place in Berlin from January 20 to 29. The sustainable crash-barrier is intended to be compatible with existing systems, just as durable and financially competitive.
