Aerated static piles require less maintenance than Windrow composting. 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. We also work to provide operator training and the automated tools to monitor key performance indicators. Aerated Static Pile (ASP) composting, refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. Introduction If you are composting food waste and garden waste, you are probably wondering how you ensure that nothing dangerous survives the composting process. After eagerly waiting for the aerated pile to cool down, we finally excavated it to an adjacent space for another round of heating before it can be screened . These systems are fixed rate, variable rate and automated rate of aeration control. Which is better composting or vermicomposting? The compost in each subdivision is finished in 8-10 weeks including curing and finishing time. It also reduces the escape of any foul odors that may emanate in the crucial first few days of the composting cycle. He is simply a joy to work with. Just because a hamburger can be made in 5 minutes doesnt mean its the best hamburger you can get. So we know the excessive aeration likely dried out the compost, and we may not have started with enough added water in the first place, but we needed to fix the moisture and fast! I like that you utilized the composite lumber. Since this ASP is in the same proximity as your CFT- would it be feasible to direct some of that exhaust heat and moisture to the CFT? I am considering starting a small (maybe 1 cubic yard or a bit more, as an initial experiment) ASP bin outdoors. In aerated static pile composting, organic waste mixed in a large pile. The manifold is the piping that takes the air from your blower to the pile and will often have several points at which it branches for the purpose of feeding several bins. i am with steve on this, Hi Steve, I have done a similar set up because of grass seeds going through the worm bins. ASP composting is particularly effective for farms where manure has a tendency to build up. The circulation of air helps get oxygen to the aerobic bacteria that break down waste while producing carbon dioxide, heat, water, and humus. Additionally, the aeration system itself can deliver airflow in various modes: positive (bottom up), negative (top down), reversing (alternating direction) and/or recirculating. Step 4: Add greens and browns. Great article. Our waste treatment technologies include in-vessel (tunnel), windrow and aerated static pile composting, and anaerobic digestion (wet and dry). If you are really wanting to geek out on airflow calculations, then see this article. 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. ASP or Aerated Static Pile composting is an . In my case, because my system is indoors, I have an exhaust fan with adjustable speed and was finding that I was likely drawing too much heat away from my ASPs so I slowed down the fan speed and saw a temperature increase within 6-12 hours. The aeration system uses fans to push and/or pull air through the composting mass. $80,000 to $100,000 Yearly.

But hot composting using the aerated static pile method is the most effective means to stabilize large quantities of organic matter, especially in a smaller space. For the front of the bins, I wanted a strong, but attractive face of the ASP, so using a 14 lumber sandwiched between 28 lumber, we were able to create a cavity in which to slide composite Trex slats repurposed from a patio renovation to finish out the front of the ASP. It may be in windrows, open or covered, or in closed containers. This is a tricky problem. ASP's are simple because they don't require turning and require less than half the area of turned windrows. -shortens the required retention time More traditional windrow or static pile compost methods by comparison may stall in cold winter temperatures. This is usually done on a schedule such as 30 seconds of air on, then 30 minutes with the air off. But validating aerated static pile composting as a method to prepare waste for the CFT was a must.). Negative pressure, where air is pulled through the compost rather than pushed, is primarily used in larger operations. You could also experience short circuits where the air fights its way through the core or up the sidewalls, allowing an easy escape for the air behind it. Hi Dan, Sorry for the late response. Its performance was compared with the classical aer ated static pi. I like and understand the minimalist approach to worm composting. As of the date of this writing, this method of extracting humid air seems to be working well. You can rely on ECSaerated static pile (ASP) compost systems to be an efficient tool to control odors and make great compost. Napa organics undergo an aerated static pile compost process. Ive been thinking a small ASP may be a starting point for a community-based precomposting for VC feedstock (much like yours but for food scraps). I adjusted it to 3 minutes on, 30 minutes off before actually re-reading O2s instructions which suggest 30seconds on, 30 minutes off. Components of aerated static pile compost : Blower Manifold Air plenum layer Active layer Biofiltration layer Blower: an electric blower (or timer) helps in inducing airflow into the compost pile by triggering the blower fan.

We work closely with the owner / site civil engineer to develop comprehensive designs for both pipeongrade systems and aeration trench systems. 3 days at 150 might be enough to kill the pathogens that are in the hot part of the pile, but that time period does not ensure that the material wont heat up on the worms. At Barr-Tech, we employ Engineered Compost System's (ECS) aerated static pile (asp) composting system. The CompTroller is remotely accessible via the web and is flexible, robust, and keeps your data safe. In large-scale systems, forced aeration is accompanied with a computerized monitoring system responsible for controlling the rate and schedule of air delivery to the composting mass, although meters and manual monitoring techniques may also be used in smaller scale operations. And what volume of compost thats good for. And I didnt offer this as a judgement on whether ASP composting is better than worm composting. ASP piles generally stay in place for about 14 to 28 days until temperatures drop or their moisture levels become so low as to limit effective composting. In Thailand this system has been used by 470 farmer groups. It can be a pretty concerning sight, especially with a large, Introduction Temperature matters a surprising amount when it comes to getting your compost heap operating efficiently, but a lot of people arent sure how hot is too hot, or whether their heap still breaks down when its cold. I wish I had space for something like that, Hi Steve, Thanks for the article. 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. In the context of vermicomposting, home vermicomposters do not need an aerated static pile in order to produce food for their worm bin. Our below-grade Low Friction Trench and Sparger pipe aeration floor collect condensate/leachate, are plug-resistant, and are designed with ease of construction and maintenance in mind. On a small scale, whatever floats your boat, I guess. Especially poo from herbivores that then becomes worm poo. So basically I chose not to try to nail down anything exact in the beginning, but to tweak the system with blower timing. Tough call. O2Compost specializes in assisting owners of existing turned windrow operations to convert over to Aerated Static Pile Composting. While we were on the right track in installing the inline fan, we made two mistakes: we installed the fan too close to the ASP and we did not have a way to catch the condensate that formed inside the exhaust manifold. See some of our cold weather deployments below, and contact us to learn more. I visited this facility in early 2019.and wow! Skip to content.

It can withstand hot compost piles and it has Bluetooth capability. Our state of the art 40-acre facility uses technology that is all natural, chemical free and reduces the production of harmful . Static pile systems require less energy but more time than windrow turned systems. Also, I treat them to some nice poop, thats free and organic. It allows the operator to set aeration rates very low (anoxic conditions) if conserving moisture and fan power is the highest process-setting priority; or higher to reduce temperature and increase drying rates. Horse manure takes a long time to decompose because it is usually mixed with bedding materials such as shavings, giving it a carbon-to-nitrogen ratio of around 75:1. Aeration involves the replacement of oxygen deficient air in a compost pile with fresh air containing oxygen. The last article in this three-part series focuses on covers. Steve, Your email address will not be published. Aerated static pile composting technology is a simple technology compared to in-vessel composting. -minimizes the footprint and associated costs In an ASP operated using negative pressure, the air itself is often pumped into a biolayer as seen in the graphic below. Thankfully, we have been monitoring temperatures daily and were able to detect the collapse in temperature and add more water quickly. These systems are fixed rate, variable rate and automated rate of aeration control. With regard to complexity and cost, aerated systems are most commonly used by larger, professionally managed composting facilities, although the technique may range from very small, simple systems to very large, capital intensive, industrial installations.[1]. Do you mix the grain and woodchips together or layer the two? The bio layer traps heat and odors and protects the active core from birds, rodents, and other vectors. If left too long, the pile would have dried to the point where I would have had to take it apart and rewet the contents before piling it again in the ASP. That is the control unit for the AC Infinity fan that I mention in the article. What is aerated static pile composting, you may ask. The ASP System is ideally suited for facilities that manage large volumes of livestock manure, yard debris, food scrap waste and other challenging feedstock materials. The composting materials are piled on a wood chip base with perforated PVC pipe running through the base and a 1 HP air pump which works for 1-2 minutes every hour. It may be in windrows, open or covered, or in closed containers. Why Are Eggshells Microwaved Before Composting? ASP Seems like it could be an answer.

No need for physical labor makes it a good option for large operations such as farms. But because I have had a few clients come visit Urban Worm HQ, I want to showcase what an ASP can do in terms of waste management. Because of the decreased compost cycle time, an ASP can be a space-efficient way to compost large volumes of waste fairly quickly. Let me know if you can All the best, Niels Corfield, This is a very complicated question because youve got to deal with pressure, length of travel, the number of turns in the pipe which create friction, blower timing, etc. To aerate the pile, layers of loosely piled bulking agents such as wood chips, shredded newspaper are added so that air can pass from the bottom to the top of the pile. Placing an ASP indoors came with challengesand we expected them! I also like to grow roses, herbs, and other things. The wood chips facilitate even distribution of air during composting and absorb moisture that may condense and drain from the pile. Air is circulated through the compost with either positive or negative air pressure, speeding up compost time by balancing the oxygen and moisture needs of the mixture. Like any pet, it can take some getting used to how to properly care for them. Aerated Static Pile (ASP for short) is a means of composting naturally occurring materials rapidly by introducing air flow to the compost pile. The selection of above grade versus below grade piping has long term impacts on operational efficiency as well as near term capital costs. At this point, the pipes are pulled out by a loader and the compost is cured and screened for sale. Seattle, Washington 98199. I know I have.
