Wilhelm-Klauditz-Institut WKI

Building the future with renewable raw materials.
Since 1946.

Sustainability has been the central theme at the Fraunhofer 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.

LIGNA 2025

 

#WeKnowWood

This is the future: houses and wind turbines made from wood and biocomposites, bio-based flame retardant solutions and closed material cycles. We develop suitable material and process solutions.

Visit us at LIGNA 2025: Hall 26, Booth B78.

We look forward to meeting you!

LIGNA 2025:
Innovative façade element for sustainable construction

At LIGNA 2025, researchers from the Fraunhofer WKI will be presenting a new type of curtain-wall element as a sustainable solution for the renovation and modernization of buildings. Not only durable raw materials such as robinia wood are thereby utilized: Less durable wood species such as spruce, poplar and kiri have also been optimized using bio-based coatings. As a result, the entire application spectrum of wood-based materials for building façades is thereby showcased. The exhibit can be seen at LIGNA 2025, Hall 26, Stand B78 from the 26th to the 30th of May 2025 in Hanover.

LIGNA 2025:
Fraunhofer WKI and TU Braunschweig conduct collaborative research for the future of construction

At LIGNA 2025, the Fraunhofer WKI and the Institute of Building Construction and Timber Structures from the Technische Universität Braunschweig will be presenting groundbreaking approaches for a resource-conserving and climate-friendly construction industry. The trade-fair presentation in Hall 11, Stand F85, will showcase activities in research and teaching revolving around the topic of building with wood and other renewable raw materials: from natural-fiber insulation materials, through timber-concrete composite systems, and on to recycling management.

Bio-based flame-retardant solutions for wood and hybrid materials

At LIGNA 2025, researchers from the Fraunhofer WKI will be demonstrating that bio-based flame-retardant coatings can provide durable fire protection for wooden furniture. A honeycomb-shaped shelf unit with the novel flame-retardant coating, as well as other exhibits, can be seen at LIGNA 2025, Hall 26, Stand B78 from the 26th to the 30th of May 2025 in Hanover.

LIGNA 2025:
Fraunhofer WKI conducts research into sustainable wind turbines

The Fraunhofer WKI is developing innovative solutions for increasing recyclability in the wind-energy sector. By taking the recyclability of rotor blades into account during their construction process, the researchers are ensuring sustainability in the material cycle. Through their expertise in the bonding of wood and hybrid components, researchers at the Fraunhofer WKI have furthermore enabled the construction of what is currently the tallest wooden tower for commercial wind turbines. The Fraunhofer WKI will be showcasing its expertise at LIGNA 2025, Hall 26, Stand B78, with an exhibit featuring the wooden wind-turbine tower, a rotor blade, and recycled products made from rotor blades.
