Researchers at Fraunhofer are transforming wood waste into biohydrogen in Germany's Black Forest through the H2Wood — BlackForest project. This initiative aims to utilize wood waste from industries like furniture manufacturing to produce biohydrogen, offering an innovative solution to traditional disposal methods. By employing fermentation processes with hydrogen-producing bacteria and microalgae, the project seeks to create a sustainable source of biohydrogen. The process involves pre-processing old and waste wood to extract sugar for microbial conversion into hydrogen, accompanied by the production of valuable by-products like starch and carotenoids. The project, funded by the German Federal Ministry of Education and Research, is expected to revolutionize biohydrogen production. The innovative biotechnological approach not only addresses the environmental issues associated with wood waste disposal but also contributes to the development of a wood-based circular economy. The biorefinery, scheduled to be operational by 2025 in Campus Schwarzwald, will feature a modular design for scalability and efficiency in biohydrogen production. With the potential to generate biohydrogen and useful by-products from wood waste, this project represents a significant step towards sustainable energy production and resource utilization.
