A compost bin, according to the present invention, comprises sidewalls and a lid which when assembled and placed on the ground, defines a closed enclosure for receiving organic material which is to be converted into compost. The sidewalls are divided into a lower section and an upper section. The lower section has a number of air entry ports for providing air to the compost material adjacent the bottom of the bin, which material is undergoing decomposition at an accelerated rate relative to organic material thereabove. The upper section of the sidewalls are closed and cooperate with the lid to act as a barrier to the entry of air into the bin and to retain heat generated by the compost reaction as well as serving to retain moisture driven from the material during the composting process. The moisture in the air is retained in the upper section of the compost bin and will condense on the surfaces of the lid and sidewalls of the compost bin when they are cooled, such as at night, to return the moisture to the material. The compost bin can further be improved by manufacturing the bin of a black material, preferably by adding carbon black to recycled polyethylene.
