Types of Hazardous Waste

Contact us

A waste is a material that you no longer need, want or use; it is something that is unusable or will be discarded, such as spent solvent. A waste is not something that you can and will use, such as leftover paint.  A waste can be considered non-hazardous (which is exempt from hazardous waste regulations), partially exempt (eligible for reduced management requirements if managed in a certain way) or hazardous. A waste may be hazardous for several reasons:

  • It displays one or more of six hazardous characteristics.
  • It is found on one of four lists of hazardous waste - the K, F, P or U List
  • It contains more than 50 parts per million (ppm) polychlorinated biphenyls (PCBs)
