Hazardous Waste

A hazardous secondary material is recycled if it is used or reused (e.g., as an ingredient in a process), reclaimed, or used in certain ways including used in a manner constituting disposal and burned for energy recovery.
A material is reclaimed if it is processed to recover a usable product or if it is regenerated (e.g., regeneration of spent solvents).
A material is used or reused if it is either employed as an ingredient in an industrial process to make a product (e.g., distillation bottoms from one process used as feedstock in another process) or if it is employed as an effective substitute for a commercial product (e.g., spent pickle liquor used as a sludge conditioner in wastewater treatment).
