Abstract

A method and apparatus for disposing of noxious landfill produced leachate and gases are provided. The method basically comprises the steps of combusting at least a portion of the landfill produced gases with air in a first combustion zone to produce a stream of hot combustion products, contacting the landfill produced leachate with the stream of hot combustion products to thereby vaporize a portion of the leachate and form a concentrated leachate residue and a composite gas stream, withdrawing the concentrated leachate residue, and then combusting the composite gas stream with additional air in a second combustion zone to convert noxious components remaining therein to non-polluting compounds.
