| 20110289992 | Unturned Covered Aerated Static Pile Composting System and Method - A method of unturned aerated static pile composting includes providing organic matter having oversized particles and forming a pile of the organic matter on a surface. The surface has a plurality of compost pipes. The method further includes covering at least a portion of the pile with an organic and particulate layer and then providing air flow through the compost pipes such that a negative air pressure is formed through the pile causing air and fluid to be withdrawn from the pile into the compost pipes. The method further includes inserting a spike in the pile at designated areas and times in order to form air shafts in the pile. The composting system includes a compost enclosure surrounding a plurality of compost pipes, each compost pipe having an air flow control valve, and at least one fan, each fan having an air intake and an air outlet. The air intake is in fluid communication with the plurality of compost pipes. The system also includes a biofilter system in fluid communication with the air outlet of the fan(s) and a spike configured for insertion into the compost pile in order to form air shafts in the compost pile. | 12-01-2011 |
