The 140Litre Twin Tumbling Composter has a unique tumbling action which speeds up the whole compositing process. Simply fill with kitchen scraps (not meat products), grass clippings, shredded garden prunings and tumble the bin regularly every 2 – 3 days. It is made from a lightweight material and its symmetrical design makes this compost bin very easy to use. It is held off the ground by a sturdy metal frame, being off the ground ensures that air and moisture are evenly distributed by the tumble action away from rodents. The barrels have ventilation/drainage holes to maximise efficiency. It has rapid decomposition and should be ready in 6 – 8 weeks.
