Beneficial Uses of Spent Foundry Sands | Sustainable

The metal casting industry generates spent foundry sands. Foundries purchase new, virgin sand to make casting molds, and the sand is reused numerous times within the foundry. This reuse eventually renders the sand unsuitable for use in casting molds, and a portion of the sand
