New wood-metal hybrid for lightweight construction

more info

Tomorrow’s building material is here today

A research team at the Fraunhofer WKI is now replacing conventional fabrics with eco-friendly natural fibers: Textile-reinforced concrete (TRC) is durable, formable in diverse shapes and suitable for lightweight construction.

Additional benefits of “NawaRo” insulation materials

Under the leadership of the Fraunhofer WKI, a consortium of twelve research institutes is conducting interdisciplinary research into holistic solutions in order to significantly increase the application of insulation materials made from renewable raw materials (German: nachwachsende Rohstoffe, “NawaRo”).

CeluPack – Pressure-resistant packaging material made from pure lignocellulose

We are developing a climate-friendly packaging material made primarily from residual agricultural materials such as corn cobs and other lignocellulose-based materials such as wood. It can be recycled together with cardboard secondary packaging.

The Fraunhofer Institute for Wood Research 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.
