Handling and Disposal
Disposal is the placement of waste into or on the land. Disposal facilities are usually designed to permanently contain the waste and prevent the release of harmful pollutants to the environment. The most common hazardous waste disposal practice is placement in a land disposal unit such as a landfill, surface impoundment, waste pile, land treatment unit, or injection well. Land disposal is subject to requirements under EPA’s Land Disposal Restrictions Program.
Organic wastes can be destroyed by incineration at high temperatures; however, if the waste contains heavy metals or radioactive isotopes, these must be separated and stored, as they cannot be destroyed. The method of storage will seek to immobilize the toxic components of the waste, possibly through storage in sealed containers, inclusion in a stable medium such as glass or a cement mixture, or burial under an impermeable clay cap. Waste transporters and waste facilities may charge fees; consequently, improper methods of disposal may be used to avoid paying these fees. Where the handling of toxic waste is regulated, the improper disposal of toxic waste may be punishable by fines or prison terms. Burial sites for toxic waste and other contaminated brownfield land may eventually be used as greenspace or redeveloped for commercial or industrial use.
