High-quality recycling of mineral building rubble and road debris and their reuse in the construction industry as secondary raw materials contributes significantly to saving primary resources and ultimately also to climate protection. RC building materials such as RC concrete granulate (mainly produced from broken concrete) and RC mix (mixture produced from various mineral materials such as broken concrete and bricks) must meet construction and environmental requirements in order to ensure safe and harmless recycling in the long term. The necessary regulations are fully available; they only need to be applied.
