Definition - What does Hazardous Waste mean?
Hazardous waste can be referred to as any waste product or substance that can pose a risk or threat to environment or public in general. Hazardous waste can have different characteristics which can determine how hazardous the substance is. There are two categories of hazardous wastes – listed wastes and characteristic wastes. Characteristic hazardous wastes exhibit these characteristics: they are ignitable, corrosive, toxic and reactive, whereas listed hazardous wastes are ideally substances that are listed dangerous by authorities because of their non-specific origin. These wastes must be treated and disposed properly in order to prevent any potential damage to the environment or the public.
