Spent Foundry Sand's Second Life: OK to Use in Some Soils

Apr 14, 2015 · The foundries reuse the sand, but over time, heat and mechanical abrasion make it unsuitable for further casting. This spent sand is then either recycled in a nonfoundry use or is landfilled. Now, possible new uses for the material include being an ingredient in manufactured soils, an ingredient in soil-less potting media and a foundation layer for roads, according to an EPA website based on the .
