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 is continuously removed and replaced with virgin sand.

Investigation of alternative ways for recycling waste

Foundry sand, an indispensable component of the metal casting process, is discarded after a number of metal casting operations. Virgin sand is then required for any new casting processes, and the spent foundry sand is treated as waste, resulting in huge amounts of discarded sand being either stockpiled or dumped into landfills.
