Sustainable aerogel materials on the basis of waste wood for the production of pollutant-adsorbing air filters and high-efficiency insulation materials with full recyclability

AltholzAerogel – Project start /

Aerogels are highly porous, light-as-a-feather materials with extraordinary properties: extremely low thermal conductivity, low sound transmission, and a high adsorption effect on volatile organic compounds. They are excellently suited both for lightweight construction and as filter materials, and are therefore considered a material of the future. In collaboration with research and industrial partners, we are developing a process for the production of aerogels on the basis of waste wood. From the aerogels, we are creating prototypes of insulation materials and pollutant-adsorbing indoor-air filters that can be utilized in buildings and vehicles. Furthermore, transfer possibilities to applications in exhaust-gas cleaning are to be demonstrated. A further project objective: The raw materials required to manufacture the aerogels are to be recovered from the products. With this sustainable material solution, we are supporting health protection as well as the fight against climate change and resource scarcity.
