Compost bin

摘要

An improved compost bin is disclosed and a ventilation channel is formed directly beneath the compost contained in the bin. A tunnel member having a perforated upper portion is contained in the channel to maintain a free passage for air to the base of the heap. The tunnel also prevents the walls of the channel from collapsing and the passage thereby becoming blocked either by the substrate on which the bin is mounted on by decomposing vegetable matter from the bin.
