Recycling Concrete Buildings Excellent Source of New Building Materials

Urban mining is increasingly being taken seriously by industry because it gives access to materials that are buried in waste tips and landfills. However, there is a new kid on the block - literally. Concrete buildings, when demolished, can serve as an excellent source of new building materials. "Instead of transporting aggregates from far away, we can use local buildings as a source for aggregates," says Francesco Di Maio, a researcher in waste separation and recycling technology at the Technical University of Delft in the Netherlands.
