ABSTRACT:
The present invention relates to a process for managing wastes and reclaiming landfill sites by using the inherent void space that exits within municipal solid waste landfills. The process comprises the injection of selected wastes and additives under pressure into the void space of existing landfills. Various materials can be added to the selected waste form such as hydraulic cement, lime, coal fly ash, waste fixing agents, buffering agents, water and plasticizers. These additives can assist in adding strength to the waste form, creating an insoluble waste material, adjusting the pH environment of the injected material, and enhancing its flowability. Depending on the waste type and additives, the process can be used to encapsulate wastes already existing within the landfill, reduce the permeability of the landfill, fix waste contaminants within the landfill to prevent them from leaching, increase the bearing capacity of the landfill, and reduce the ultimate settlement of the landfill. The process can also be used to increase the rate of consolidation and reduce the height of the landfill, or if appropriate organic sludges are added, the process can be used to enhance the rate of biodegradation of organic materials within the landfill, and to increase the rate of landfill gas production and methane gas recovery.
