ABSTRACT:
A low-cost compost bin with air tubes or air panels which is easy to assemble and use. The bin is comprised of two flexible sheets which form a cylinder. Two openings are located on opposing sides of the cylinder. As material to be composted is piled in the bin, perforated air tubes are positioned at vertically spaced intervals in the composting matter. The air tubes are placed in the composting matter so that each end of the tube faces one of the openings. The air tubes provide sufficient oxygen to the composting mass and therefore, no manual turning, stirring or tumbling is required.
