A land disposal unit, or LDU, is a site in which hazardous waste is remedied through natural and man-made processes. "Land disposal" of hazardous waste is defined in the U.S. Resource Conservation and Recovery Act (RCRA). [1] Types of LDUs for hazardous waste disposal: Landfill; Surface impoundment; Waste pile; Land treatment unit; Injection well
A land treatment unit (LTU) is a location in which land is treated, usually through bioremediation processes, to reduce the toxicity of the soil. Land treatment units are areas where hazardous waste is applied or incorporated into the soil surface. Land treatment units are typically units consisting of natural soils where natural biological and ...
Dredging contaminated sediment in New Bedford Harbor, Massachusetts. The harbor is contaminated with polychlorinated biphenyls (PCBs).. Environmental remediation is the cleanup of hazardous substances dealing with the removal, treatment and containment of pollution or contaminants from environmental media such as soil, groundwater, sediment.

Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.
The disposal of toxic waste continues to be a source of conflict in the U.S. Due to the hazards associated with toxic waste handling and disposal, communities often resist the siting of toxic waste landfills and other waste management facilities; however, determining where and how to dispose of waste is a necessary part of economic and ...
It is most commonly used in the context of land-filling of putrescible or industrial waste. In the narrow environmental context leachate is therefore any liquid material that drains from land or stockpiled material and contains significantly elevated concentrations of undesirable material derived from the material that it has passed through.
Today, the disposal of wastes by land filling or land spreading is the ultimate fate of all solid wastes, whether they are residential wastes collected and transported directly to a landfill site, residual materials from materials recovery facilities (MRFs), residue from the combustion of solid waste, compost, or other substances from various ...
The distinction between these terms is crucial because waste management confusion leads to improper disposal of materials by people on a daily basis. Biodegradation technology has led to massive improvements in how we dispose of waste; there now exist trash, recycling, and compost bins in order to optimize the disposal process.
