A waste stream represents debris of a similar type and make up. The paint debris from a given structure represents a single waste stream if the coating system and method of removal is constant. The debris represents a different waste stream, if different coating materials or methods of removal are involved. For example, the waste created when using recycled steel grit generates a different waste stream than waste created using a disposable abrasive (e.g., coal slag) even though the paint being removed is the same.
