FOUNDRY SAND WASTE. Foundries create metal castings for use in the automotive, art, construction, agriculture, and mining industries. In this process, molten metal is poured into a mold, usually made from sand or ceramics. As castings are created, the sand has to be removed and replaced due to abrasion from the high heat and mechanical stress.

[Environmental Toxicity of Waste Foundry Sand]

The five waste foundry sands had quite different compositions and levels of VOCs, which resulted in different levels of inhibition effects on the luminescent bacteria (30% and 95%). Additionally, the soil DHA tests suggested that metal pollutants in waste foundry sands may inhibit the soil microbial activity, whereas organics in the sands may
