The global construction industry devours enormous quantities of fresh raw materials, in particular in the production of concrete. How can resource efficiency be improved? In collaboration with our project partners in Germany and China, we are developing sustainable concrete construction materials and high-performance construction elements on the basis of construction and demolition waste as well as plant-based production residues. One particular focus here is the identification of suitable recycling processes as well as the adaptation of the construction products and all the process steps for the German and Chinese markets. We thereby offer a solution that can be rapidly implemented in order to significantly increase the proportion of renewable raw materials in the construction industry. Simultaneously, we are creating economically interesting perspectives for the agricultural and forestry industries, recycling enterprises and mechanical-engineering companies, as well as for the insulation and construction industries.
