This Living Lab under the title “CarbonThink” provides the opportunity to recycle previously unused resources (e.g. 4.000 m3 of manure per year) in the form of biochar. This has many benefits: biochar is able to store CO2 and is particularly suited for composting, as it contributes to soil fertility. Furthermore, the production process of biochar releases thermal energy, which can be used for heating instead of fossil fuels. Therefore, the use of this process not only ensures a closed cycle along with reducing greenhouse gas emissions at Freie Universität Berlin, but also reduces the costs for waste disposal and energy supply. The interdisciplinary research project aims at the connection of sustainability-focused research and teaching and offers the chance to develop new teaching formats.
