Up to now, wood waste has had to be disposed of at great expense and, at best, has been used to generate energy in incineration plants. Fraunhofer researchers are now using this valuable resource to produce biohydrogen in the Black Forest region of Germany. In the joint project H₂Wood — BlackForest, fermentation processes using hydrogen-producing bacteria and microalgae have been specially developed for the biotechnological production of this green energy carrier. A pilot plant for the production of biohydrogen is to be commissioned as early as 2025. A study published as part of the project also examines the potentials, barriers and measures for regenerative hydrogen production from waste wood and old wood in the Black Forest region.

There is fresh momentum in our protein supply — and it’s moving along on six legs. Insects are a source of protein with a smaller resource footprint than conventional alternatives in every possible way. To ensure the safety of insect farms and their products, Fraunhofer researchers have developed a system that reliably detects pathogens right away, at low cost and with the possibil-ity of automation.

Ammonia plays an important role as a transport and storage medium in the hydrogen economy. Promising solutions for its use as an energy vector are currently being developed in the Fraunhofer flagship project AmmonVektor. But how great is the potential? And where are the limits? The workshop “Ammonia – THE supply chain for the hydrogen economy?”, on October 30 in Oberhausen, will provide an overview of the latest technologies and developments and provide impetus for the energy transition.

Production of fine chemicals such as those used in pharmaceuticals is typically complex and laborious. An interdisciplinary team of Fraunhofer researchers worked together across different projects to devise a method modeled on a cascade, in which multiple successive stages of synthesis proceed without interruption. This is made possible through the use of novel catalysts in specially adjusted flow-through reactors. The new method makes the process of manufacturing drugs more efficient and conserves energy. In this way, the modular technology platform supports the production of pharmaceuticals in Germany as an industrial location.

The EU has banned animal testing for cosmetics and non-animal alternative methods are preferable for the risk assessment of new chemical substances. At the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB, a three-dimensional skin model has now been set up for the first time that directly displays the skin's reaction to substances: The reporter skin. Thanks to the built-in reporter, the cellular response can be measured precisely and quickly – using a living model. This means that not only cosmetics can be tested effectively, but also allergens and the inflammation-causing or toxic effects of biocides, pesticides and chemicals.

Regional conflicts over the use of water resources are rather common and will continue to intensify as a result of climate change and the increasing strain on natural water resources. Water-intensive agriculture in particular is dependent on efficient solutions. In the HypoWave+ research project, a farm in Lower Saxony is currently implementing a particularly water-efficient process for the hydroponic cultivation of vegetables using high-quality recycled wastewater. On August 20, 2024, media representatives are invited to explore the large-scale implementation as part of this scientifically supported living lab.

Invasive infections such as sepsis require immediate and targeted treatment. Experts from the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and group partners have succeeded in establishing a reconceptualized detection principle that can make a crucial contribution to saving lives through fast, ultra-accurate pathogen identification. They have been chosen to receive the 2024 Stifterverband Science Prize for their efforts.

Researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB have developed a biobased and functionalized flocculant to efficiently treat complex wastewaters. Furthermore, toxic phenols are removed from the water by the enzyme laccase in a chitosan matrix. The functionalized and degradable flocculant LaChiPur will be presented for the first time at the IFAT in Munich from May 13–17, 2024.

Adhesives are almost always based on fossil raw materials such as petroleum. Researchers at Fraunhofer have recently developed a process that allows to utilize keratin for this purpose. This highly versatile protein compound can be found, for instance, in chicken feathers. Not only can it be used to manufacture a host of different adhesives for a variety of applications, but the processes and end products are also sustainable and follow the basic principles underlying a bio-inspired circular economy. The project, developed together with Henkel AG & Co. KGaA, addresses a billion-dollar market.

Reproducible in-vitro canine skin has been grown in a laboratory setting for the first time by researchers at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB. The research team developed a full-thickness dog skin equivalent based on native skin cells. This makes it possible to precisely test medical treatments in vitro on the sensitive skin of dogs. The skin equivalent can even be used to test the compatibility of care products such as shampoo or soap - eliminating the need for animal testing.
