EPA estimates that approximately 2.6 million tons of spent foundry sand is beneficially used outside of foundries annually, with iron, steel and aluminum sands representing 96 percent of the foundry sands that are beneficially used. Currently, only about 14 percent of those sands are beneficially used in soil-related applications.

for silica sand was in foundry casting. How-ever, the progressive decline in UK heavy manufacturing, and notably the foundry industry, resulted in a steady reduction in the demand for foundry sand (Figure 2). Over 4000 foundries were operational in the UK in the 1970s, this has now reduced to several hundred. This decline appears to have stabi-
