Green Mountain Technologies has developed the patent pending Circular Turned Aerated Pile System or cTAP compost system. A circular design is a more efficient layout for large turned aerated pile systems. The reason is that moving compost towards the center of a circle takes advantage of the volume reduction experienced during composting. As you get closer to the center the area of the rings get smaller at the same rate that the compost is shrinking. This allows a  7-acre cTAP system to process up to 560 tons per day of compostable materials and provides 30% more capacity than a rectangular design. The other big advantage is that your turner never needs to turn around… it just keeps going in a circle. Maximizing your capacity while reducing your labor is what cTAP is all about.
