Every ton of steel produced generates byproducts that are often overlooked yet hold untapped value. One of the most important of these byproducts is mill scale—a flaky, dark, iron-rich material that forms on the surface of hot-rolled steel. For decades, mill scale was treated as waste, swept away and discarded.

Slag is one of the world’s oldest and most widespread industrial byproducts. Formed during the smelting or refining of metals, it has been both a challenge and an opportunity for industries for thousands of years. Today, slag recycling offers manufacturers, steelmakers, and foundries a chance to reduce waste, recover value, and support sustainable growth.

When companies think about waste, they often picture costly disposal and complex regulations. But what if that same material could become a resource instead of a liability?
