"We installed an O2Compost system at our barn where we keep four horses for our personal use. It has three 6' x 6' bins into which we place the barn waste and manure removed from the pastures. We add in kitchen scraps and litter from our indoor cats. The system yields rich organic compost that we place on planting beds on our property or give away to neighbors. This system is an excellent solution to the challenge of waste management."

"I am thrilled with the system. It is exactly what I wanted and is doing exactly what I envisioned. Not only have we used it all over our 20 acres here at the farm, but we also hauled 20 yards to add compost to the flower beds at our home in the city. There is no odor and the plants and flowers are thriving. Our bees love it, our vegetables and flowers love it, our grazing pastures love it, our animals love it, and we love it because our land is so lush. The ecosystem is coming alive with animals and birds that have never been here or have not been here for a long time. It is incredible to see what attracts wild animals with a good foundation of soil!"

"I contacted O2Compost after failed attempts to compost with manual pile turning. With Peter Moon's guidance, I have now met my compost production goals. The aerated Benchmark System is an attractive, efficient, and environmentally friendly way to manage horse manure and create a marketable compost product. It helps with fly populations and minimizes weed distribution. We have family nurseries, tree farms, and master gardeners who are all amazed that our product does not smell and produces very healthy plant life. I am pleased to report that the proceeds and donations received in return for gifts of compost directly benefit the Rhythms of Grace non-profit program. The system works!"

"Wanting to be good stewards of the environment, we began searching for methods to make our farm as much of a closed system as possible. We found Peter Moon and O2Compost back in 2008 but we are a nonprofit organization, so it took some time to raise funds through grant writing and soil conservation cost-share programs to get the project underway. During this time, we continued to research and visited other facilities that had much larger systems in place. We were impressed with the way O2Compost seemed to live up to its promises. The composted manure and bedding we saw was fine, relatively odorless, and did not seem to have an insect burden around the composting bins. Our Cornerstone system was finally completed in 2012 and we love it. We look forward to expanding the uses of our composted materials."

With the O2Compost system, that process is going to happen in a much shorter time frame. I highly recommend reaching out to Peter Moon and the folks at O2Compost. I found them to be very helpful and encouraging."

"We installed the O2Compost system when we built our barn in 2020. We have five horses we clean up after -- mostly in the fall and winter months when they're in their paddocks. The system has worked as advertised. It's amazing to see our bins of manure heat up well above 130 degrees, killing all the bad stuff. I've needed to call Peter Moon a variety of times to consult and he has been so helpful. He knows the science of this process like the back of his hand! We've had our finished compost analyzed by some folks at the university extension, and the report we got back was that our compost has all the exceptional qualities you want in compost. Our boys have started their own little business in the springtime selling compost to neighbors. They call it Two Brothers' Poop! The neighbors love the compost in their gardens and flower beds."

"We were using the windrow method and it was taking years before our material was fully composted. Not only was this ineffective and costly to keep the large piles turned, but it also took up valuable space. The O2Compost system helps me create a more consistent compost in less time and helps me maximize my composting area. Setting this up and building the piles was smoother than I anticipated. I am pleased with how quickly the temperatures rose and were maintained with the blowers. We have cut down on our equipment time and fuel which is a huge savings."

"As an Environmental Biologist and horse person whose farm drains into a fish bearing waterway, I knew we would need to have a bulletproof manure management system for our equine sanctuary herd. For many years prior to starting our nonprofit, I had researched many manure containment and composting options and it was clear that O2Compost systems were head and shoulders above the rest in regards to speed of composting, lack of runoff, and the production of a high-quality compost product that we could use on our pastures to increase forage and soil health. We also donate to community gardens in our area.

We are grateful to Peter Moon for his work in sizing a system according to our needs, providing clear and easy-to-follow plans, and for his support with any and all of our questions. We know that we can call Peter and he will find the answer for us and we appreciate his friendly expertise! Six years down the line and we are still just as excited as ever about our Cornerstone system, and we love to educate folks on the importance of creating a cradle to cradle system for our farm waste."

Working with Peter has been such a great experience. It was very reassuring and educational to have his regular support as I got started. In general, a very professional operation -- worth the investment for sure. Even on a 6 degree morning, my active pile reached 130 degrees in the center. The compost is odorless and pretty much ready to go when the process finishes."

"We have been so impressed with O2Compost on so many levels. We use our system to compost horse manure from 40 horses. There are no flies and no smell. Peter is always available for questions. The system is easy to use and is saving us a ton of money since we no longer have to pay to haul the manure off the property. As a bonus, I feel great about the positive environmental effects in not wasting this valuable resource in a landfill; creating healthier pastures for our horses and creating pastures that absorb more carbon dioxide as compared to non-composted pastures. It is truly a win-win."

"We are a small urban farm composting on our own property with neighbors 10 feet away from one of our compost bins! We wanted to work with an industry expert and have found Peter Moon to be really helpful and knowledgeable. The O2Compost system allows us to aggressively keep down and manage any smells so that we can be good neighbors. The designs are straightforward and it's ingenious how the Micro-Bin panels can be used in different configurations in our limited space. Totally worth it."

"I have 2 horses on a small 5 acre parcel.  The idea of having an unsightly bin in my yard and paying someone to haul away a perfectly good resource seemed preposterous to me, as did the idea of being environmentally irresponsible and risking contamination of the sensitive moraine on which I am privileged to live.

O2Compost was an investment which I have never regretted - my neighbors probably don't even realize I have a manure management system as there is no smell.  People are always surprised that there are no flies buzzing around.  I use all on my compost to augment my sandy soil to give my "boys" a chance to graze on some grass, and also in my yard for landscaping purposes.  I even use the compost unmixed in raised planters to grow amazing tomatoes and arugula, and share it with friends who want a boost for their own gardens. I would recommend this system wholeheartedly to anyone."

"The designs and support I got from O2Compost helped me to “get smart” very quickly because Peter and his staff were always available to answer my questions. The O2Compost system has been flexible and scalable enough to support our exponential growth - our food waste collection service has grown to be an around-the-clock operation. 

I have watched composting facilities around the state open and close because of permit violations. Meanwhile, my O2Compost system has operated odor and incident free since 2013 and at a fraction of the cost of competing ASP systems. Peter Moon and his expertise have been instrumental to my success."

"Equine farming near a water resource area can be challenging due to the very nature of waste management of manure.  Before we built our O2Compost system we had a number of visits from the state regulators regarding storage, use and effluent.  We have eliminated any of their concerns with the construction of our system.  The result is visually pleasing and odors are virtually nonexistent, while producing a product that can be used safely on the farm or as a new revenue stream from compost sales.

I initially sold everything I could produce but I have eliminated any advertising because it is such a good soil amendment that I want to use as much as possible on my own fields.  That said, I still take care of my return customers who show up primarily in the spring or fall and that at least pays for the operation of the system."

"I have been recycling food scraps via insulated ASP composting since 2016. In addition to household food scraps, I collect and process pre- and post-consumer food residuals from restaurants, coffee shops, a juice bar, and East Tennessee State University. This includes meat, cheese, breads ... you name it! I also use municipal leaves and wood chips in my mix.

Even though I had already had a fair amount of experience with composting, paying O2Compost for consulting was one of the best decisions that I made. They freely share their wealth of technical knowledge, and they are extremely quick to respond. O2Compost’s input during the design and permitting stage and their continued support since I have been in operation have been invaluable. I strongly encourage you to contact them!"

"We LOVE O2Compost and recommend it all the time!! We compost horse manure and fine pine bedding from two horses. We have three boxes: one filling, one aerating and one curing. We use the finished compost to spread on our orange trees, new plantings, or often just spread the compost on the horse’s dirt turn out area to improve the soil and offer softer footing over time. Occasionally, when it rains here, we will seed the horse’s turnout, then lay the finished compost over it and fence it off with hot wire to create a small grass area for the horses to graze on."

"O2Compost's aerated compost bins have been a wonder for our urban farm business, which believes in promoting local healthy food production on the West Coast of Vancouver Island, Canada. We have been diverting food scraps from the landfill since 2012 for 50 households and 8 commercial businesses, and have been making beautiful compost instead. With our aerated Micro-Bin, turnaround time is much quicker than regular backyard composting and there is no need to hand turn the piles (a relief on our backs!).

And what fantastic fruits and veggies are grown with this plant super food! For making the composting process smooths and succinct, we believe O2Compost is king."

As a landscape architect I knew the value of good compost but hadn't been very successful with my own attempts in my garden. With Peter's guidance and very easy to use system, I have been able to help my family's farm create a rich and valuable compost; compost that I am proud to see used on the farm's fields and to sell to my contacts in the landscape industry. I am so thankful I found him and his company and can't say enough good things about this system!"

"I co-advised an organics research project with a Polytechnic 8th grade student group. The goal was to find a more sustainable way to manage the food and yard waste that our K-12 campus generates. After seeing the O2Compost ASP system at the Rose Bowl, students chose to further research the science of composting as well as the systems designed by O2Compost. The company owner, Peter Moon, generously offered us an hour of his time so that the students could interview him about the ASP system. Peter clearly enjoyed engaging with the students and seemed genuinely impressed with the breadth and depth of their research. Polytechnic School leaders granted the students' request for funds to pilot two Micro-Bins. Peter helped minimize the costs by encouraging the students to write a Request for Proposal, which led to O2Compost donating the aeration equipment and construction plans. Peter has been incredibly supportive and sees the value of young people engaging in this type of real-world sustainability problem solving."

"Spinning straw into gold - that is sort of what we were looking for when we saw how the manure pile was growing bigger with each stall cleaning, but we were having to buy the compost to put on our gardens. Our 3-bin aerated O2Compost unit will help us turn manure into compost time and time again, perhaps not as quickly as saying Rumpelstiltskin but certainly more reliably. Building our unit went pretty smoothly with the itemized materials list and step-by-step instructions, and our first pile heated up quickly. We continue to experiment with the right mix and layering and how to best work our new system, but we know Peter is standing by the phone (or computer) if we need help. We are looking forward to working our way through the manure pile and aerating manure into nutrient-rich soil for years to come."

We have now partnered with a local vineyard to provide worm castings for 25,000+ vines. We use the O2 system to take the pressed grapes and make an AMAZING compost.

"I have known Peter Moon and his staff at O2Compost since 2004. I needed a system that would handle renderings from a chicken/turkey processing plant, food waste from Blue Hill Restaurant, and mortalities from the Stone Barns Farm. When I explained to Peter that this needed to be a very clean processing system he assured me it would cover all of my needs, and it has.

Now I am a partner with Compostwerks LLC in Mt. Kisco, New York and we sell only his composting systems. Plain and simple … they work. They are scalable, easy to set up, they last and, most of all, they are affordable. Equally as important, they have a great staff to back up their packages."

"Reunity Resources composts food waste from schools and restaurants in the Santa Fe area. Mulch and manure are also included in our composting process.  We've been using an Aerated Static Pile system since January 2015 and couldn't be happier with the results. We frequently refer colleagues to O2Compost because our results have been so positive.

This system has prevented over a million pounds of food waste from going to the landfill and created thousands of cubic yards of nutrient-rich compost to support area farmers, gardeners and ranchers. Having now started multiple gardens and farm plots by simply amending the depleted high desert soil with compost, we can attest to the results in terms of plant health: vegetable yield and drought resilience are excellent. Lab tests continue to reveal impressive micro-worlds within the finished compost as well!"

"I built three bins in 2013 to compost the manure from our three horses. Over time, we've accrued a rich, worm-filled, odor-free composted mound that we share with our vegetable-growing neighbors and spread on our large flower garden. The only problem we ever encountered was when the temperature dropped below zero for an extended period. We were filling bins with manure 'ice cubes' that wouldn't chemically 'ignite' to start the composting process. After consulting with Peter Moon, the following winter we used an agricultural heating wire that we laid over the first foot of frozen manure and covered over. Within a week, the pile had heated up and the chemical reaction had started. We used the wire again this winter and didn't have any issues with frozen manure."

Horse manure is collected and composted in my O2Compost aerated bays which not only eliminate the need for turning but also create a more consistent end product than ordinary composting in a static pile.
