The three chambers in this composter separates the new and old organic waste from each other to effectively speed up the composting process. Organic matter that has begun to break down in the first chamber is released to each subsequent chamber to continue the process of decomposition. With each chamber/stage typically running on a 3-5 week cycle the whole process has been designed to produce up to twice as much compost as other stand-alone composters in the same amount of time. In addition to its three chamber system the Earthmaker boasts an ample 466L capacity effective ventilation not to mention large access and collection areas. The instructions manual can be found HERE.
