GMT offers two blower control systems that automatically regulate the aeration system using temperature feedback. Even many of the larger commercial worm farms in the US use windrows (long piles) turned by a compost turner in order to perform pre-composting, which is the preparation of organic waste by incompletely composting material. ASP piles are easily monitored and the process can be managed by adjusting the blower timing to meet the needs of the large-scale vermicomposter. We are seeking a candidate with experience managing all aspects of composting operations including daily processing of material, supervision of employees, maintaining safety standards, compliance with government regulations, and the sales/marketing of end products. Worms create their own energy out of the food you provide them. Full-Time. The blower provides direct control of the process and allows larger piles. That was a very informative article Steve ! Reasoning: My worm bin is six pallets tied together with zip ties. In this article, were going to look at the different temperatures, and talk about finding the perfect. It may be in windrows, open or covered, or in closed containers. 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. To prevent this, an air plenum layer, often a simple layer of wood chips, is laid atop the perforated manifold. Super cool Steve! So at the very least,learningabout composting was an imperative. Im excited to investigate further. I had enough space for two large bins or three smaller ones. Those are expensive and designed to take work out of the worms, or to keep you from getting your hands dirty. Sizing compost systems too big or too small can cripple a projects financial returns. Tarp systems can be used during wet weather to prevent saturation or to limit vector access to the compost. Livestock and equine farms have seen great success using ASP systems. 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! These systems are fixed rate, variable rate and automated rate of aeration control. The pile is covered with a fabric which is impermeable to water. 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. And I assume that this dryness caused my compost to fall below 50% moisture content and cease the composting process as my temperature collapsed to 100F from about 130F in about 2 days time. This would be better on a large scale, however, again, its not green. Stuff, I mean tomatoes, potatoes, vegetables, and other things that are tasty and good to eat. Once our team has received your request, we will start working on your custom composting solution. We built up the bin walls using cinder block and mortar, ultimately capping the top with 28 treated lumber. Join our newsletter to hear periodic updates on compost science and our latest projects. For the average composter, this ASP system is highly unrealistic. Aerated static pile The ASP method is a versatile approach to composting. Which is better composting or vermicomposting? Call or email us to get started. Aerated Static Piles (ASP) are a simple and efficient way to compost challenging feedstocks like food waste, biosolids and manures. Aerated Static Pile or ASP systems have been the standard for providing aeration to active compost piles for over 40 years. Steve. We get commissions for purchases made through links in this post. Aeration can also be affected by wind, moisture content, and porosity. Learn more below, or contact us to schedule a visit and 'smell the difference'. Do you have any comments, observations or recommendations about the noise level and how to dampen it? Aerated Static Pile (ASP for short) is a means of composting naturally occurring materials rapidly by introducing air flow to the compost pile. Facebook Twitter YouTube LinkedIn. Compost produced through the ASP system was similar in quality and maturity to the product from normally managed windrows after 30 days. Skip to content. Because the oxygen is more or less involved in the composting process, it is also called aerated static pile composting or aerobic static composting. A 15-inch squirrel-cage blower was used to force the air through 10 static piles of compost, one at a time, for 15 minute periods twice a day. 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. HOW DO YOU CONTROL THE PROCESS? Alternate between layers of greens and browns, ensuring your scraps are covered well by browns to not attract pests | Learn More > Step 5: Maintain your pile. However, aerated systems can dry out quickly and must be monitored closely to maintain desired moisture levels. You can rely on ECSaerated static pile (ASP) compost systems to be an efficient tool to control odors and make great compost. This type of system can produce compost within three to six months. In the most basic terms, an aerated static pile has 5 components: The blower and timer I received from O2 Compost is a simple bounce house blower and an analog cycle timer with simple dials to allow you to control the on/off cycle to your liking. 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. ASP composting is particularly effective for farms where manure has a tendency to build up. The probe is meant more to be an air probe although temperature is temperature and it works just fine for us. Compost feeds the soil. Aerated static piles have been used for centuries by farmers to create compost for their crops. Lasaridi, E.I. Thanks Steve! ASP's are simple because they don't require turning and require less than half the area of turned windrows. Also, I treat them to some nice poop, thats free and organic. The selection of above grade versus below grade piping has long term impacts on operational efficiency as well as near term capital costs. These systems are fixed rate, variable rate and automated rate of aeration control. This is counter-intuitive, but excessively dry compost will become hydrophobic and will not absorb water. Turning on the blower will cool the compost, removing excess biological heat while adding oxygen to the pile. Aeration involves the replacement of oxygen deficient air in a compost pile with fresh air containing oxygen. But you can monitor your ASP system manually or with a simple thermostat. Whether you are looking for an option to recycle your organic waste or you simply want to improve the conditions of your existing compost pile, you may want to consider aerated static pile composting. Very cool. The systems of aeration control currently available for "Aerated Static Pile" composting are reviewed. I would run the system for at least 4-5 weeks *and* until the temperatures start trending downwards. Because I live in suburban Philadelphia in Zone 7A, producing consistent output in the winter was going to be difficult. No need for physical labor makes it a good option for large operations such as farms. We patented this and the Radial Aerated Static Pile in 2017. It is best to buy the pipes with holes instead of wasting the time drilling holes yourself. With that in mind, lets look at a compost temperature to kill pathogens ( Temp guide lines). HOW DO YOU DESIGN AN ASP SYSTEM? But the challenge with an indoor system is the moisture generated by the composting process. Its not very green; its actually costing more energy to process the compost. I have a small set up with 50L bins and use small 12v air pumps for each bin. If youre interested in a mid-scale composting project or want to start a small composting business, then this book needs to be on your bookshelf! 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 compost in each subdivision is finished in 8-10 weeks including curing and finishing time. It is 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), such as local governments, landscapers, or farms. The Aerated Static Pile (ASP) is the simplest and least cost approach to composting large volumes of organic waste materials. Aerated systems also facilitate the use of biofilters to treat process air to remove particulates and mitigate odors prior to venting. It can withstand hot compost piles and it has Bluetooth capability. The raw materials consisted of agricultural wastes and animal manure in the ratio of 3:1 by volume. Efficient design of the piping system is critical for even distribution of air in a compost pile. Once you understand what each part of the system does, its operation is quite intuitive. Aerated Static Pile or ASP systems have been the standard for providing aeration to active compost piles for over 40 years. GMT also offers below grade piping systems that substantially reduce the labor associated with setting up each pile. I would enjoy a conversation with you. Aerated static pile composting is an effective method to accelerate and manage the composting process with much lower risk of foul odors. i am with steve on this, Hi Steve, I have done a similar set up because of grass seeds going through the worm bins. On a small scale, whatever floats your boat, I guess. When Should I Stop Adding To My Compost Heap? 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. In-vessel composting can also refer to aerated static pile composting with the addition of removable covers that enclose the piles, as with the system in extensive use by farmer groups in Thailand, supported by the National Science and Technology Development Agency there. Cheers! ASP is a hot composting method that uses the purposeful movement of air through waste materials to make them compost rapidly, even in a small space. Learn about the different compost cover options and how they impact compost performance. These operations tend to be larger and more advanced. Steve. Resources to learn about PFAS an their impact on compost. We have the expertise and agility to build, own or operate alternative waste treatment facilities in Australia. 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). So again on Peters recommendation, I opted to install my aerated static pile composting system indoors in a horse stall in the first floor of my barn, which is conveniently adjacent to my CFT. Way beyond my ability though! This method is used in countries with a lot of rainfall, where it is difficult to get an aerobic compost pile going.

In the blower timing section above you show a photo of a digital temperature (and moisture?) I am not and likely never will be a large-scale vermicomposter. WA CC GREENMT852CS He is simply a joy to work with. As the compost process begins, temperatures quickly climb over a period of about one week, rising to 150-160F, as long as the moisture level is correct. Air is extracted via 4-in inline fan. Your email address will not be published. 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? The purchase also gets you lifetime customer support from Peter! (May, 2008). Job Description. Aerated Static Pile Composting In-Vessel Composting Learn more about the types of composting and the composting process (link leaves DEC's website). At this point, the pipes are pulled out by a loader and the compost is cured and screened for sale. There is something that the worms leave in the process of processing the organic waste that makes it infinitely better for plants to grow. I recommend his system so please let him know I sent you! However, my 1/4 HP blower is enough to run 3 ASPs simultaneously, granted with different airflow than if I were only running one ASP. The piles also can be placed over a network of pipes that deliver air into or draw air out of the pile. However, aerated static pile composting requires MSW Collection Transfer Transport Treatment It is a good idea to feed the material afterwards to the worms. Vermicomposting This method uses worms to degrade materials. 21 days or so? Would like to see if you have info on the amount of airflow needed for a given volume of compost. What is aerated static pile composting, you may ask. 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]. I was likely drying out the compost with excessive airflow. 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. The aerated static pile method takes the piped aeration system a step further, using a blower to supply air to the composting materials. The most common configuration is an Aerated Static Pile (ASP), followed by In-Vessel and Aerated Turned Pile (ATP) systems. The Worm-Free Way to Compost in Your Apartment, Composting Schedule and Time Frame (When Should You Start?). Learn more here. Its performance was compared with the classical aer ated static pi. Natural aeration occurs when air warmed by the composting process rises through the pile bringing in fresh air from the surroundings. I chose the 3-bin option and with the help and guidance of my employee Mark, a retired engineer, we dug the initial trenches for the underground manifolds and poured the footers for the ASP walls. 122K subscribers Static aerated composting (aka an aerated static compost pile or ASP) is a system by which the composter does not need to turn the compost, but rather uses pipes. But validating aerated static pile composting as a method to prepare waste for the CFT was a must.). You can rely on ECS aerated static pile (ASP) compost systems to be an efficient tool to control odors and make great compost. At Barr-Tech, we employ Engineered Compost System's (ECS) aerated static pile (asp) composting system. More traditional windrow or static pile compost methods by comparison may stall in cold winter temperatures. I own a small company collecting poop about 30 tons a year. Just as a data point, could you share what the cost of the plans were from O2? Compost materials are piled on top of ridged or flexible perforated pipes. 800.610.7291 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. Composting is a biological process which slows down when material freezes. There are 3 main types of composting:Aerobic Aerobic composting uses air to facilitate composting. 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 following components are needed for a home or industrial aerated static composting pile system: Anything you would add to a backyard compost bin can be added to an ASP composting system. My cost was of course higher than that, but this was the O2 Compost part of it! Covered and Aerated Compost 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. And if you mix any tips on doing that without killing yourself? This is a tricky problem. A large-scale operation with a multi-pile system can cost upwards of $100,000. Hi Ben, I paid $795 for the plans which came with the blower, the timer, some of the needed manifold parts, a really good booklet about ASP. Our designs focus on optimizing process control, which thereby: Meeting the temperature requirements in our permits and for use on organic farms will only take 3 days at 131 F with ASP, which . It is easily scalable in both size and technology ( Table 6.1 ). We work closely with the owner / site civil engineer to develop comprehensive designs for both pipeongrade systems and aeration trench systems. The intangible part of the deal is lifetime support from Peter. Solutions focused on highly mature final compost. 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. 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. It is 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), such as local governments, landscapers, or farms. The blended admixture is usually placed on perforated piping, providing air circulation for controlled aeration. This is usually done on a schedule such as 30 seconds of air on, then 30 minutes with the air off. The aeration grid is usually made of 100- to 150-mm (4- to 6-in.) Cheers! 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. Napa organics undergo an aerated static pile compost process. I know I have. 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. Compost needs to, Introduction Have you ever wondered why compost often seems to steam? Green Mountain designed the 27th Ave Composting Facility in Phoenix. One of the most economical, time-saving composting syles is aerated static pile composting. 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. 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. This article is an introduction to aerated static pile composting and will discuss: And well close out with a description of my own custom ASP system at the Urban Worm Company and my own first couple weeks of operation before pointing you towards some helpful resources for learning more about aerated static pile composting. The separated solids are stacked for transfer to our static pile aerated composting shed. Using blowers alongside temperature, moisture, and oxygen monitors to finely tune the composting process, positive CASP systems are ideal for all types of feedstock, including food waste, green waste, biosolids, and source separated organics. For a multi-bin or pile system, you will need some fairly expensive on/off ball valves to prevent expending airflow on piles that dont need it at the time. -shortens the required retention time The active layer is comprised of whatever material youre planning to compost, whether its high-nitrogen food waste, manures, or other organic waste. Compost materials are piled on top of ridged or flexible perforated pipes. 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. Great article. Perhaps utilizing a (raised bed) hoop house setup thats sturdy but removable? On Peters recommendation, I purchased the plans, blower, and some manifold parts for the Micro-Bin. This happened about 7 days into the thermophilic heating period which ought to last 21 days or so. Aerated Static Pile (ASP) composting, refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. yes i am going into the worm business, and yes i am building an asp system. Step 4: Add greens and browns. Steve, Your email address will not be published. I feed them all kinds of crap and collect leaves during the fall for their bedding, and disperse it over the year. I only get bigger and poop amounts increase. Figure 7.5 shows an aerated static pile process of composting. But if you have more questions than answers about composting, we can help. The process decreases the composting . 1. Static pile composting is a number of systems to biodegrade organic material without physical manipulation during primary composting. Because of the decreased compost cycle time, an ASP can be a space-efficient way to compost large volumes of waste fairly quickly. Windrow Aerated static pile Rotary drum compost-ing Substrates Waste was chosen for Preferable for more ho- All sorts of waste, but those with reduced mogeneous and con- suitable for readily de-odor emissions, such as sistent waste, and the graded waste .

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. If youve recently built a compost heap and youve seen clouds of white droplets rolling off it, you might be panicking, and wondering whether youve done something wrong, or if this is dangerous. Even if the odor werent an issue, nearby neighbors might not appreciate the hourly blowing of the fan. Introduction If you are composting food waste and garden waste, you are probably wondering how you ensure that nothing dangerous survives the composting process. These pipes provide controlled aeration and allow for a slow, natural decay process. Keep up with the great posts, Awsome Barry. A week after this modification, so far so good! So while learning about ASP composting was necessary to help market the CFT,actually doing the composting was important to operating it effectively. As this horse stall measures 12 x 14ft, I had to decide how I wanted to divide the space. Just because a hamburger can be made in 5 minutes doesnt mean its the best hamburger you can get. Rigid or flexible perforated piping, connected to fans, delivers the air. Many, but not all, cover systems include some form of forced aeration, using pumps to push or pull air through the pile core. Air enters the mixture through a series of pipes and loosely piled bulking agents. And it can do it in colder climates that might not be as conducive to year-round composting. The pile is covered with a fabric which is impermeable to water. Adolescent humor alert: For those of you who are familiar with dutch ovens, the bio layer is the sheet that traps the heat and odor. 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. Automated page speed optimizations for fast site performance, compost with either positive or negative air pressure, speeding up compost time, Active layer The active layer is the compost, Compost begins aerobically composting within the active, This includes all manner of organic waste and food, composting operations use computerized systems to monitor the temperature. It is designed to achieve regulatory compliance; offers operators a broad range of process options; and provides each pile/zone with independent and automatic control for achieving process goals. This is the author's latest innovation, using a bouncy house fan connected to the manifold with an innertube to provide airflow under the compost pile. Hi Steve, What materials do you compost in your ASP system? I adjusted it to 3 minutes on, 30 minutes off before actually re-reading O2s instructions which suggest 30seconds on, 30 minutes off. It can take a year or more, it stinks, and it increases the risk of producing bacteria. The same blower control and manure sensory system used for the aerated static composting bins is also utilized with the large pile setup. Composting organic waste is a simple and effective method to maximize positive environmental . Aerated static pile (ASP) composting refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. The piping is connected to fans that circulate oxygen through the pile. (Note: The ASP I am operating is not large-scale. In fact, its tiny. And I didnt offer this as a judgement on whether ASP composting is better than worm composting. A large factor in this cost is leveling and preparing an area to place the system. 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. Advantages such as a means of . The last article in this three-part series focuses on covers. And in order to produce a consistent feedstock for my CFT, I knew I needed a manageable way to produce compost from a consistent source, in this case, horse manure from a nearby stable. You can build or buy a compost bin for less than $100, but youll end up putting a lot of work into this system because it will need to be turned every few weeks but monitored daily. It expedites the process of decomposition, without having to wait a year or more like you would for anaerobic composting. ASP is a hot composting method that uses the purposeful movement of air through waste materials to make them compost rapidly, even in a small space. If were being honest, its not green, expensive, and impractical. I wish I had space for something like that, Hi Steve, Thanks for the 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. All Rights Reserved. Aerated static pile composting is an effective method to accelerate and manage the composting process with much lower risk of foul odors. Costs. It also maintains the population and diversity of beneficial oxygen-consuming bacteria and has the benefit of controlling the foul odors that anaerobic composting emits. The air is delivered on a preset schedule that can be tweaked according to the wishes of the operator, but a typical cycle is 30 seconds on, 30 minutes off. Fortunately, ECS has developed some cold weather techniques to facilitate semi-optimized process conditions even during harsh winters. a biofiltration layer, often comprised of mulch, compost, or even very expensive Gore covers. Aerated static piles offer process control for rapid biodegradation, and work well for facilities processing wet materials and large volumes of feedstocks. Reasoning: The monitoring, the timer, the blower; all these things require energy. The compost in each subdivision is finished in 8-10 weeks including curing and finishing time. / 206.319.7102 The process uses a mix of organic materials placed on perforated piping. Home; Services. Advantages of this composting method include the ability to maintain the proper moisture and oxygen levels for the microbial populations to operate at peak efficiency to reduce pathogens, while preventing excess heat, which can crash the system. ECS is committed to helping our customers maximize composting stabilization while minimize capital cost. It diffuses the air and delivers a more uniform air flow to the entire pile. 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. In my case, there is a single manifold splitting into 3 underground manifolds, each of which can be opened or closed with a shutoff valve. Youve got two different types of pipes, pvc and metal, 2x4s, 4x4s, plywood, electrical gadgets, and of course the 895 in plans. The best compost, however, is worm poo. However, they are easy to assemble and offer a hands-off option for individuals as well. For anyone who is operating at the community composter level and below, this blower/timer combo is likely to be sufficient. In the context of vermicomposting, home vermicomposters do not need an aerated static pile in order to produce food for their worm bin. WHAT FEEDSTOCKS COMPOST WELL WITH ASP? that is just one reason. The compost in each subdivision is finished in 8-10 weeks including curing and finishing time. I have to say, it wouldnt surprise me if the ambient temperature were kept high enough in the barn due to the ASPs. Thanks for the advice I will put put it to good use. What is aerated static pile composting, you may ask. It is concluded that only the automated aeration system can actually cater for the dynamic nature of the composting process. asp will fix that . ECS aerated static pile systems (ASP) can offer the following standard features depending on your operation needs: The aeration system distributes air through the biomass to enhance composting conditions. Channeled concrete floor of a composting pad for perforated piping that delivers oxygen to the composting mass, List of solid waste treatment technologies, Edmonton, AB, Canada Co-composting facility, Agricultural and Food Processing Wastes Composting In Thailand by Aerated Static Pile System, https://en.wikipedia.org/w/index.php?title=Aerated_static_pile_composting&oldid=1125851099, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 6 December 2022, at 05:53. Because of the decreased compost cycle time, an ASP can be a space-efficient way to compost large volumes of waste fairly quickly. Who has killed many goldfish by throwing them in a bowl and feeding them flakes? Hey Robert! Hi Dan, Sorry for the late response. I am considering starting a small (maybe 1 cubic yard or a bit more, as an initial experiment) ASP bin outdoors. The Grand Opening of Northern Recycling's Covered Aerated Static Pile Composting and Construction, Demolition, and Inert sorting facility will be held on Wednesday, September 28, from 9 to 10 am, located at 44090 County Rd 28H in Woodland. All ASP systems work exactly the same way. Hey Rebekah, Glad to have you get this off your chest! Aerated static pile composting allows for all types of organic waste to be mixed together into one large pile. We also work to provide operator training and the automated tools to monitor key performance indicators. Worms and dirt go hand in hand, or slimy long body in hand. The major difference between the technologies is the amount of energy and labor required. The pile is covered with a geo-textile fabric which is impermeable to water. The manure solids are moved a static-pile composting bay where they will cure for 60 days. The design can be used for over 500 kg of organic waste, with minimal leachate, to produce a soil enhancer for agricultural fields, gardens, and/or forest land. All aeration components in contact with the composts corrosive exhaust air-stream are made from stainless steel or polymeric materials. Proudly Powered by The Pixel Pantry. I wondered if you knew what the airflow is for your blower. Tough call. 4220 24th Avenue West It is inherently simple but readily accommodates more sophisticated techniques when warranted. -speeds up the process The Web's #1 Resource for Vermicomposting Information. Composting and Energy Recovery. It can be combined with aerobic composting to speed up the process even more. Damper position is automatically set by the control system. 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. No turning or agitation of the materials occurs once the pile is formed. I hate sending to land fill. Also if I decide to compost cow or horse manure at what point would it be okay for my worm bin? This book has been an incredible resource for learning more about aerated static pile composting. I wanted to enquire about blower noise. If you are really wanting to geek out on airflow calculations, then see this article. Steve, And you definitely need more than 3 days of high temperatures. The schedule 40 and SDR 45 pipes come either solid or with holes. Solution forced air into the bins. Table 6.1.

I also like to grow roses, herbs, and other things. phone: (201) 848-9699 | lincolnlandscape@gmail.com. The aeration system is designed to conserve energy with variable speed fans, and adaptive control strategies. i have and waste lots of pig poop. Our systems feature dynamically controlled aeration with a wide range of air delivery rates required to keep oxygen and temperature at Best Measurement Practice levels throughout the pile. Negative pressure, where air is pulled through the compost rather than pushed, is primarily used in larger operations. The pipes can be installed in channels, on top of a floor, or included throughout the pile during buildup. Aerated static pile composting technology is a simple technology compared to in-vessel composting. The parts of course have value, but being able to get in touch with the expert is also very valuable! Great article. I like and understand the minimalist approach to worm composting. We want to learn more about your project goals. If the pressurized columns of air escaping the perforated manifold piping were to come into contact with the active material, you would risk drying out several different pockets of your composting material. The bio layer traps heat and odors and protects the active core from birds, rodents, and other vectors. The piping is connected to fans that circulate oxygen through the pile. Pre-composting kills pathogens, releases heat, and reduces volume like normal composting. Compared to traditional backyard composting, ASP composting is a little more expensive. The blended admixture is usually placed on perforated piping, providing air circulation for controlled aeration . Especially poo from herbivores that then becomes worm poo. In recent years, smaller scale in-vessel composting has been advanced. 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. How long would I run the system like this for? Motorized dampers control airflow and direction to each pile. Steve. ECS CompTroller is an automated aeration control and monitoring system that is operating at all ECS compost installations. Now, you may have put a lot into your worms in the beginning. 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. Temperature feedback is the best way to regulate an ASP system. 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. In the aerated static pile method of composting, the poultry litter pile is not turned, and temperatures above 50 C can be maintained for over 290 days (4). I have been looking to recycle hot compost dog poop for viable worm food. So I opted to enclose my bins and rig up flexible dryer ducting to a PVC manifold which uses a sweet little 4-in inline ducted fan made by Cloudline in order to extract the heat and moisture generated by my system and push it outdoors. Stentiford, 1998 Some aerated static pile composting systems operate on negative pressure, meaning air is sucked through the system.
