A polyhedron composting container (10) is disclosed having an access door panel (15) and interior turning tines (18). The polyhedron composter (10) is advantageously manufactured from identical equilateral triangles which can snap or fasten together by bolts or the like. Vents (20) are provided either in the individual panels (11) or by hollow tines (18), or both. Here composter (10) is manufactured in the shape of a isocahedron to facilitate aeration through easy turning and further to simplify loading and unloading of composter (10).
