The Joraform compost tumblers are the pinnacle of compost bin design and can break down material incredibly quickly due to the high levels of heat built up inside the unit, such as - uniquely amongst composters - meat and fish waste from your kitchen. These composters are odour free and do not attract pests or rodents. While they are expensive, they are definitely the best compost bins for speed and ease of use, and allow saving money on bin charges with added bonus of making highest grade compost for yourself-saving even more money. So in time - the Joraform unit pays for itself.
