Materials Management

Beneficial use of solid waste is a sustainability practice that may involve using an industrial waste in a manufacturing process to make another product or using a waste as a substitute for construction materials.

DEQ has standing beneficial use determinations and makes other beneficial use decisions on a case-specific basis:
