While states' approaches to regulating foundry sand reuse are similar to those used for regulating industrial waste reuse in general, sand reuse programs specifically consider the characteristics of foundries and used sand, and the likely reuses. The many binders, curing processes, raw materials, and metals used in the casting process all affect the composition of foundry sand.
