The German construction sector uses 600 million tons of mineral construction raw materials annually. As just 81 million tons of construction waste are recycled and used as building materials, only 5 percent of construction waste is attributed to high-quality products in the construction industry. The majority of utilised mineral construction materials are produced with primary raw materials.
The finite nature of natural resources and the scarcity of landfill space are growing challenges for resource management, which cannot be solved by current approaches of construction waste recycling technology.
For this purpose there is an increasing emphasis on sustainable building in the construction sector. Hence a research consortium comprising various project partners was established forcing the challenges of resource conservation, reuse of building materials and a high-quality recycling of construction material.
