Production of recycled sand from construction and demolition waste

The project is a presentation of how sand can be recycled from construction waste and demolition rubble. She shows how massive problems can be solved by reclaiming the necessary sand from rubble on construction sites.

This practice would not only reduce the large volume of waste produced in São Paulo – 500 to 1,000 kilos per person per year – it would reduce the transport of sand, which represents a high cost for the construction industry.
