Abstract: A compost retention unit with removable partition is provided. The compost retention unit includes mesh retention material secured to interconnected frame structures such that the mesh retention material and the plurality of frame structures can cooperate to retain compost within the unit when the unit is fully assembled upon a generally flat surface. The removable partition can be secured to provide separate enclosures, and can be removed to facilitate transfer or turning of the compost. Preferably, the compost retention unit can be collapsed for storage or shipment and expanded to assemble the retention unit for use. Preferably the compost retention unit includes three rectangular frame structures which pivot to assemble the compost retention unit for use. Most preferably, the frame structures are made of four lengths of wooden “two-by-four” or “two-by-six” framing materials, and the mesh retention material is preferably a wire mesh material.

Abstract: A compost retention unit is provided. The compost retention unit includes mesh retention material secured to a plurality of pivotally interconnected frame structures such that the mesh retention material and the plurality of frame structures can cooperate to retain compost within the unit when the unit is fully assembled upon a generally flat surface. In preferred embodiments, a first frame structure can pivot 180 degrees with respect to a second frame structure when the unit is being assembled. The most preferred retention unit includes three rectangular frame structures, preferably made of four lengths of wooden "two-by-four" or "two-by-six" framing materials, and the mesh retention material is preferably a wire mesh material.
