The Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut WKI specializes in process technology, natural-fiber composites, wood protection and emission control, quality assurance of wood products, recycling procedures and the use of organic building materials and wood in construction. Almost all the procedures and materials which result from the research activities at the Institute 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 and the automotive industry.

K 2019 trade fair: Fraunhofer WKI presents ecological crates

Conventional vegetable crates made from petroleum-based polypropylene are used millions of times every day. The researchers at the Fraunhofer WKI have worked out how to make the containers more sustainable, lighter and sturdier – whilst keeping production costs at the same level. At K 2019, they will be presenting vegetable crates comprised of up to 25 percent wood fibers.

Timber buildings withstand global warming

Wooden buildings withstand climate change and help bind CO2. This is the result of a study carried out by the Fraunhofer WKI together with the Holzbau Deutschland-Institut. For future construction planning, the researchers have also developed recommendations for protection against heat, wood pests and extreme weather events such as storms and heavy rain.

Sustainable sandwich elements for building construction

In a joint project with the TU Braunschweig, the Fraunhofer WKI has developed an innovative building element for the construction industry: a sandwich element with a wood-foam core and a thin cover layer of textile-reinforced concrete. The proportion of particularly sustainable construction materials in buildings can thereby be increased.
