Hazardous waste management hierarchy is a systematic approach used to manage hazardous wastes according to the level of environmental and health protection provided by different management options. It gives priority to methods that prevent the generation of hazardous waste and reduces the need for treatment and disposal.

Industries can prevent waste by changing production processes, using less hazardous raw materials, improving
