The pipes can be installed in channels, on top of a floor, or included throughout the pile during buildup. On Peters recommendation, I purchased the plans, blower, and some manifold parts for the Micro-Bin. Hey Robert! For anyone who is operating at the community composter level and below, this blower/timer combo is likely to be sufficient. Aerated Compost, also known as Aerated Static Pile Composting, ASP Compost, and Forced Air Compost, is a form of hot composting which requires less maintenance. Step 4: Add greens and browns.

It can be combined with aerobic composting to speed up the process even more. Stentiford, 1998 As of the date of this writing, this method of extracting humid air seems to be working well. Natural aeration occurs when air warmed by the composting process rises through the pile bringing in fresh air from the surroundings. Thankfully, we have been monitoring temperatures daily and were able to detect the collapse in temperature and add more water quickly. Steve. Static pile systems require less energy but more time than windrow turned systems. I have to say, it wouldnt surprise me if the ambient temperature were kept high enough in the barn due to the ASPs. If you are really wanting to geek out on airflow calculations, then see this article. Aerated static piles (ASP) offer process control for rapid biodegradation, and work well for facilities processing wet materials and large volumes of feedstocks.

This series of articles has established that aerated static pile (ASP) composting is increasing in the U.S. composting industry due to the potential for better process and odor control and, when covered, for potential improvements in odor management and storm water runoff quality. On the suggestion of Michigan SoilWorks owner Dan Lonowski, we moved the fan farther away from the ASP and placed a PVC tee upstream of the fan with a narrow drain tube to carry the condensate away. Reasoning: The monitoring, the timer, the blower; all these things require energy. Hey Rebekah, Glad to have you get this off your chest! Hi Dan, Sorry for the late response. The ASP concept is simple: Place perforated pipes on the ground that are connected to a blower to push (positive) or pull (negative) air through the compost. 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. It is suitable for small community-scale operations and very large ones. Aerated Static Pile (ASP) composting, refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. Stuff, I mean tomatoes, potatoes, vegetables, and other things that are tasty and good to eat. I was composting turning my bins every week but due to work commitments I was unable to turn them and the bins would become anaerobic. -shortens the required retention time No turning or agitation of the materials occurs once the pile is formed. In recent years, smaller scale in-vessel composting has been advanced. Worms create their own energy out of the food you provide them. ECS offers several different below and above grade aeration floors that distribute air through the biomass and are compatible with loading and unloading using front-end loaders. Once you understand what each part of the system does, its operation is quite intuitive. ECS applies composting science and best engineering practices to our equipment designs to facilitate process control and enable our customers to achieve low odor operations. It does not log any information though. However I live in an urban area (houses are touching each other) and was concerned about the noise generated by the blower, especially at night. Just because a hamburger can be made in 5 minutes doesnt mean its the best hamburger you can get. Me too! There are four types of aerobic composting: Aerated Static Pile, In-Vessel, Aerated Turned Windrow, and Vermicomposting.

A biofiltration, or bio layer is a simple covering of mulch or finished compost surrounding the active core which protects the pile from heat loss and pests. In an ASP operated using negative pressure, the air itself is often pumped into a biolayer as seen in the graphic below. Too much aeration over-cools the pile and slows the process down. can handle wetter compost than traditional composting, can compost large amounts of compost in a small area, easy to maintain moisture and oxygen levels, and, therefore, the temperature of compost, dry out faster than other compost methods and require careful monitoring, requires extra materials (finished compost, compost fleece, or mulch). If your inline fan was at the exhaust from the CFT row cover- what would that do for/against the overall dynamic?
