It is piled in an enclosed area and aerated from the outside. This system can manage large quantities of waste and makes it particularly suitable for manure or large volumes of food waste. Each pile (there are two shown) measures 550-feet long x 85-feet wide x 12-feet tall (~20,000 cubic yards each). John Paul. Mixed feedstock material is placed in long rows called windrows. The major difference between the technologies is the amount of energy and labor required. Static pile and turned windrow technologies were investigated on a commercial scale with the composting of nearly 300 tons of material. Static pile composting is a number of systems to biodegrade organic material without physical manipulation during primary composting. Static pile systems require less energy but more time than windrow turned systems. Covering compost piles with breathable fabrics can help reduce water needs during hot, dry weather, and may help avoid soggy, anaerobic piles during periods of heavy rain. . " " STATIC PILE INOCULATED COVERED COMPOST (SPIC) Making quality compost using a no-turn method Types of Waste and Waste Generators: Aerated static piles are suitable for a relatively homogenous mix of organic waste and work well for larger quantity generators of yard trimmings and compostable municipal solid waste (e.g., food scraps, paper products), which might include local governments, landscapers, or farms. Which should be sufficient. Covered and Aerated Compost Systems. For static composting, organic matter is piled up and then broken down by bacteria. Organic waste is mixed together in one large pile instead of rows. Compost. The Anatomy of an Aerated Static Pile . The aerated static pile process consists of mixing of dewatered sludge with a bulking agent (usually, wood chips), construction of the composting pile over the grid of aeration piping, composting, screening of the compost, and curing and storage. The aerated static pile method takes the piped aeration system a step further, using a blower to supply air to the composting materials. Compost increases the water content and retention of sandy soils.
