Hazardous Waste. Some foundry processes have the potential to generate hazardous wastes within the plant. These processes include the following: Ductile Iron Production/Melting
Our recycled sand and slag operation is just one of the many ways we’re reducing our environmental impact. Over the years, we’ve invested in equipment upgrades that improve our ability to recapture and reuse foundry sand within our own operation. These process improvements allow us to use less new sand while also throwing away less spent sand.

Slag is a by-product of smelting (pyrometallurgical) ores and used metals. Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous/base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus).
