The construction industry needs large quantities of gravel and crushed rock for concrete manufacturing. So far, recycled concrete has mostly been utilized as filling material or in substructures, but only hesitantly for structural engineering. The film shows how recycled concrete can be processed applying new methods to enable its use as an alternative building material even in structural engineering. The proportion of the building material able to be processed into high-quality products after a demolition can be considerably increased, which in turn reduces the environmental impact significantly.
