Project description „BauCycle“ for Verbund Materials Flyer
The German saying “as the sand of the sea”, which literally means “a ten a penny” has lost its validity. In many countries in the world the valuable resource sand is disappearing continuously. The main reason therefor is the boom construction sector which consumes vast quantities of concrete comprising mostly of sand and gravel. Every year around 40 billion tons of sand and gravel are consumed and on the other hand around five million tons of fine grained construction waste accrue in Germany every year. Until now this waste has been used as landfill or road construction material. Different Fraunhofer institutes (IBP, IML, UMSICHT, IOSB) have set themselves the task to process the construction waste in a way to generate a new sustainable material. The big goal of the project »BauCycle« is to reuse the construction waste below two millimetre particle size and to cover the whole value chain from developing innovative sorting processes and high-quality construction materials up to the development of a dynamic virtual commodity exchange.
