At Hannover Messe 2026, the layer structure of a door from Rodenberg Türsysteme AG can be seen, in which wood foam has been utilized as a structural element. The partners Fraunhofer WKI and Butterweck Holzstoffe GmbH & Co. KG are thereby demonstrating an application possibility for wood foam in combination with classic wood-based materials. The wood foam developed and patented by the Fraunhofer WKI is produced and distributed by Butterweck Holzstoffe GmbH & Co. KG.

Fraunhofer WKI warmly welcomes Dr. Kusum Saini as an “International Climate Protection Fellow” of the Alexander von Humboldt Foundation. During her research stay from March 2026 to the end of February 2028, Dr. Saini will conduct research at Fraunhofer WKI into innovative approaches for developing bio-composite building materials from agricultural waste.

From 18 to 20 March 2026, the Fraunhofer WKI will be presenting the first interim results of the “LuminousNetworks” project at the Wissenschaftsschaufenster Braunschweig (Science Showcase Braunschweig, located at Waisenhausdamm 8). “LuminousNetworks” focuses the spotlight on fungal mycelium as a material. As a sustainable and functional resource, mycelium has already become a game-changer in the development of biomaterials. Through the works of artist Malte Taffner, who is involved in the project, the fungi now shine in a completely new kind of light.

Professor Tunga Salthammer from Fraunhofer WKI and Professor Lidia Morawska from Queensland University of Technology recently published an article in the journal WIREs Climate Change, in which they examine an important question: What does climate change mean for indoor air quality, i.e., in homes, offices, schools and other buildings?

Sustainability is an aspect that more and more consumers pay close attention to when buying furniture. As part of their research project titled LinumTube, researchers from the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut, WKI have created modern seating furniture that is easy to disassemble, adapt and transport, and is also highly recyclable. The modular systems are made of only two materials: fabric produced from natural fibers and steel tubes.

Fall is the peak season for mushroom fans, as the moister conditions and falling temperatures are ideal for promoting the growth of fungi. However, when Dr. Henrik-Alexander Christ and Dr. Steffen Sydow from the Fraunhofer WKI set out in search of fungi, they are not only interested in the fruiting body: For the researchers, the thread-like network of hyphae, the so-called mycelium, is particularly exciting. It is found under the soil and its abilities can be exploited for the production of various materials. The two researchers are investigating the potential of mycelium-based materials for use in, for example, the construction industry.

The search for sustainable materials is gaining increasingly in importance – including in the construction and furniture industries. In order to meet this demand, researchers at the Fraunhofer WKI are developing bio-based adhesives on the basis of renewable raw materials and biogenic residues. In the “LowEPanel” research project, they are testing formaldehyde-free adhesives made from lignin and hydroxymethylfurfural (HMF) for the production of sustainable particle boards using regional wood residues. This enables them to develop high-quality bio-based materials, thereby optimizing the value chain. Bio-based adhesives are a key technology for the bonding of materials and the conservation of finite resources, and represent a promising growth market. As a result of the research being conducted at the Fraunhofer WKI, particle boards are becoming more ecological and easier to recycle.

Right now, the only factor determining when a road needs resurfacing is the condition of the road surface itself. However, the state of the asphalt layer beneath it is also an important marker that has not been adequately taken into account until now. To assess it, only indirect measurement methods are available, which either measure only the surface or damage the road by drilling. A new monitoring system from Fraunhofer researchers and partners detects damage early on and continuously monitors the condition of the underlying asphalt layer, comprehensively and without causing any damage. The centerpiece of the new solution is a fabric of sensors inside the asphalt. AI algorithms to analyze the data are also part of the system. Going forward, the researchers hope the interaction between the sensors and AI will help assess the condition of road structures in real time.

Wood is constantly gaining in importance as a natural and sustainable construction material for buildings. As yet, however, no satisfactory fire-protection solution exists for wood in exterior applications. A lack of flame retardancy is an exclusion criterion for wooden components in tall or large-scale buildings, unless an expensive and time-consuming approval is applied for in individual cases. In collaboration with project partner German Textile Research Center North-West (DTNW), researchers at the Fraunhofer WKI have developed an environmentally-friendly flame-retardant coating for wood surfaces which are exposed to the elements.

To protect the environment, especially the ocean, many single-use plastic products are banned in the EU. But single-use products made from unmodified natural polymers are allowed. With this in mind, researchers at the Fraunhofer WKI have teamed up with partners to develop compostable single-use tableware based on local agricultural residue from sugar production.
