Technology for Wood and Natural Fiber-Based Materials

Due to climate change, the supply of high-quality softwood is becoming increasingly problematic. In the FutureWood project, are investigating the raw material quality produced by differing silvicultural systems, taking into account the climatic and ecological aspects. We are applying the gained knowledge in the conception of optimized silvicultural systems and manufacturing procedures for the forestry and timber industries in order to safeguard the sustainable production of high-quality coniferous-wood products.

Window and façade profiles made from plastic are extremely popular due to their durability, low maintenance and good recyclability. In cooperation with the University of Stuttgart, we are developing profiles made from bioplastics in which regionally available plant residues, such as wheat straw, are used as filler material. 

We are developing a environmentally-friendly wood foam-textile-reinforced concrete sandwich element for exterior walls of energy-efficient buildings with small component thickness.

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 project sounds incredible: is it possible to foam wood? As part of an internal pre-research project, the Fraunhofer WKI has developed innovative methods which enable the production of foams from pure wood.

A new method was implemented in order to produce aminoplastic resins on the basis of melamine and alternative aldehydes and to apply these as adhesives for wood materials and decorative coatings.

Building upon the knowledge gained from a prior project, the development of formaldehyde-free, low-cost (compared to melamine resins) urea resins for use as adhesives in wood-based materials and as impregnation resins for decorative paper coatings now seems promising.

In this project, we are currently developing binding agents which use formaldehyde-free resins based on melamine and naphthalene with improved characteristics for construction applications.

The collective term "waste wood" is used to denote all woods and wood-based products whose end of life as a product has been reached and which therefore fall under the definition of waste. Sources of raw materials which have, until now, only been insufficiently utilized should now be developed.

The Fraunhofer Institute for Wood Research WKI is responsible for research on the waste wood cascade demonstrator. The aim of the project is to develop methods and technologies that the usable amount of pure wood fraction increases significantly in the future. Moreover, adhering to the timber contamination, coatings and ingredients to be detected and also recycled.

Wind turbines are producing increasing quantities of sustainable electricity. The recycling of the rotor blades, however, has been very complicated and expensive up until now. We are developing an innovative recycling technology for the recovery of balsa wood and plastic foam from the rotor blades as well as recycling procedures for these recyclates, in order to utilize them in the production of new, improved insulation and building materials.

Due to both the globalization of the timber trade and climate change, there is an increasing risk of wood-destroying insect species being introduced and spreading rapidly, thereby causing extensive damage to German forests. Previous control procedures for the timber trade are not sufficient. The objective of our research project is to therefore develop an effective control procedure in order to provide support for the timber trade and the forestry sector.

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. Within the Fraunhofer WKI, four departments are participating in the project. In our department we are working on the project segments “Thermal insulation” and “Moisture protection”.
