Abstract: An apparatus and a method for composting organic material, wherein a plurality of frame members are spaced from each other, and a plurality of support members are connected to each frame members. Hollow, perforated conduits are connected to and extend between corresponding support members of adjacent frame members. The conduits are movable vertically along the support members. An evacuator withdraws fluid from the compost material through the conduits, and an injector may inject treatment material into the compost material through the conduits. An analysis system is provided to analyze the composting state of the organic material and to determine any treatment necessary required by the organic material as a result of the analysis of the composting state.
