Foundry sand is high quality silica sand that is a by-product from the production of both ferrous and non-ferrous metal casting industries.

Silica-based spent foundry sands produced by iron, steel and aluminum foundries can be safely reused to save energy, reduce the need to mine virgin materials, and reduce costs for both producers and end users.
It also has the following applications: -
• As an ingredient in manufactured soil;
• As an ingredient in soil-less media (potting soil); and
• As a foundation layer of roads (subbase).
