Abstract
Abstract Method and means for disposing of solid waste by using a portable incinerator, in conjunction with a continuous sanitary landfill trench. The method consists of progressively incinerating the waste within the trench with a portable incinerator, and then covering the solid residue, after combustion, with a sanitary landfill. The means consist, in general, of a refractory cap having depending side and end members, which progressively compartmentize areas of the trench with means to sustain combustion in the compartments, means to scrub the combustion gases, and means to move the entire assembly along the trench.
