Foundry Sands Recycling - EPA

The spent foundry sand, that is, the sand that is removed, is either recycled in a non-foundry application or landfilled. Estimates are that less than 15 percent of the 6-10 million tons of spent foundry sands generated annually is recycled. The Agency believes a greater percentage of spent foundry sand can be safely and economically recycled.
