Abstract
Apparatus and method for performing sequential batch anaerobic composting on high solids content wastes are provided, wherein a plurality of longitudinally extending trenches in the ground are employed as waste-holding receptacles, each of the trenches being provided with a cover having a peripheral skirt depending downwardly therefrom to be submerged in a water-containing moat surrounding the periphery of each trench to hermetically seal the trench. The covers contain leachate sprayers and offgas recovery piping which are connected to a fixed piping system of the apparatus, and hoppers, conveyor belts and discharge plows are used to transfer the waste into the trenches, and a lifting conveyor is used to transfer the waste out of the trenches back onto the conveyor belts extending alongside the trenches. The method involves using leachate recycling in a three stage process which employs the trenches having the removable covers.
