The present invention is directed to a process and apparatus wherein municipal refuse, and many other types of solid waste, are disposed of in a landfill repository that maintains them in a dry state indefinitely. This eliminates most environmental and many cost problems. The principal design feature of this landfill is its cellular internal structure, which has rows of contiguous, rectangular water- and gas-tight cells that are built on top of one another to form a high, multi-layered structure. These cells are simultaneously constructed and filled with solid waste in a series of short, incremental wall berm construction and filling steps on a one-cell-at-a-time basis in the top layer of the landfill. The sides of the structure and the tops of the cells in the top layer are continuously protected from rain infiltration by impervious covers, and uncontaminated rain waters, leachates, leakage, and gases are separately withdrawn from the system on a cell-by-cell basis by an internal plumbing and monitoring system. Biodegradation is used in cells in the top layer to produce methane gas.
