Listed wastes are wastes from common manufacturing and industrial processes, specific industries and can be generated from discarded commercial products. Characteristic wastes are wastes that exhibit any one or more of the following characteristic properties: ignitability, corrosivity, reactivity or toxicity. The P and U lists designate as hazardous waste pure and commercial grade formulations of certain unused chemicals that are being disposed.
