Early 2019, Heidelberg Materials was looking for an innovative solution for concrete recycling to recover its original components i.e. aggregate, sand and cement paste.
Most of the existing solutions are in fact crushing the concrete down to 0/22 mm fractions with high reduction ratio. The customer was looking for a separation concept with low crushing ratio to recover the aggregates and sand from concrete as clean as possible from cement paste. The ReConcrete-360° project started.
