Innovative approach for recycling building materials
Around five million tonnes of fine-grained building rubble are produced in Germany every year. Up to now, this fine fraction has been disposed of in landfills and partly reused as subsoil in road and landfill construction. In order to recover the valuable raw materials used in concrete, such as sand or gravel, and to be able to return them to the production cycle, four Fraunhofer Institutes have set themselves the goal of realising an innovative recycling system for fine-grained demolition waste. The "BauCycle" project was launched for this purpose. The researchers are looking at the entire value-added chain - from innovative optical sorting processes and logistics networks to the development of high-quality building materials. This material reuse of demolition waste is intended to sustainably conserve primary raw materials and counteract a shortage of landfill space.
