Hazardous waste

[Rennhack]

Waste products that can pose a substantial or potential hazard to human health or the environment when improperly managed. Hazardous waste is regulated at the federal level under the Resource Conservation and Recovery Act. A waste may be hazardous because it has at least one of four characteristics - ignitable, corrosive, reactive, or toxicity--or it may be included on one of several lists of waste groups that are known to be hazardous.
