To aerate the pile, layers of loosely piled bulking agents (e.g., wood chips, shredded newspaper) are added so that air can pass . The aerated static pile is the simplest and most cost effective approach to composting large volumes of organic waste materials and providing the requisite environmental controls for . ASP's are simple because they don't require turning and require less than half the area of turned windrows. In aerated static pile composting, organic waste is mixed together in one large pile instead of rows. A series of perforated pipes ( or equivalent ) air distribution system runs underneath the compost pile and is connected to a blower that either Many, but not all, cover systems include some form of forced aeration, using pumps to push or pull air through the pile core. Mixed feedstock material is placed in long rows called windrows. No turning or agitation of the materials occurs once the pile is formed. Air enters the mixture through a series of pipes and loosely piled bulking agents. SG's aerated static pile design has lower energy consumption compared to negative aeration, reverse aeration and timed positive aired systems. This method of forced aeration accelerates the composting process, allowing us to deal with waste more efficiently. Covered and Aerated Compost Systems.

Aerated static pile method of composting generates compost relatively faster (3 to 6 months). Water savings from the aerated static pile system averaged around 20 percent, and the footprint needed for the ASP system is some 55 percent smaller than that required by windrows. With EASP composting, fresh air (with oxygen) is blown into the pile under positive pressure to maintain aerobic conditions throughout the pile, eliminate the need for pile turning, accelerate the decomposition of the organic waste material, achieve pathogen reduction . The optimal pH is between . Read the full report PDF . Aerated static pile (ASP) composting, using negative aeration and simple timer motor controls, was developed by the U.S. Department of Agriculture's Beltsville Agricultural Research Center in the 1970s in support of exploring the beneficial uses of sewage sludge. #2: ASP Composting Dramatically Reduces the Cost of Composting Operations The amount of heat determines whether the pile is considered hot or cold: SGS use of proprietary remote oxygen and temperature control system technology makes for the most cost-efficient processing. We can't help with A, but for B, we overcome that need to turn a pile by pumping air straight into the pile using aerated To aerate the pile, layers of loosely piled bulking agents (e.g., wood chips, shredded newspaper) are added so that air can pass from the bottom to the top of the pile. Sometimes the temperature stayed above 131 degrees F., as is stated in the organic rule, sometimes the temperature dropped below 131 degrees. Each pile (there are two shown) measures 550-feet long x 85-feet wide x 12-feet tall (~20,000 cubic yards each). Aerated static piles require less maintenance than Windrow composting. Because the oxygen is more or less involved in the composting process, it is also called aerated static pile composting or aerobic static composting. What is Aerated Static Pile Composting? Video Summary: Most composters will fail because they: A) don't use enough high-nitrogen material or B) they don't turn the pile enough to keep it oxygenated. Through a 319s grant funded by Massachusetts Department of Environment Protection, two Aerated Static Pile (ASP) composting systems, also known as forced aeration were installed to manage livestock manure and bedding produced on Blue Star Equiculture Farm in Palmer, Massachusetts.
