Country Oaks Landscape Supply ~ Burton, Michigan

Installed in January 2020! Country Oaks Landscaping supply produces US certified, grade A compost on 15 acres in Michigan. We are so thrilled to share with you their new 2020 video featuring our very own Brian Jerose, along with owner Mark Cherry.

As explained in the video, our AGT Compost Hot Box 250-8R System is already saving the business on operating labor, physical space, and energy costs between reduced diesel consumption and through heating their shop and sales building with the recovered compost heat. Equally important for the customer, the system has addressed odor issues from handling large volumes of fresh grass clippings. This had generated complaints from neighbors and the municipality last year and through better oxygenation the situation has been resolved. View full project details here.

Tamarlane Farm ~ Lyndonville, VT

Tamarlane Farm is a diversified Vermont organic dairy and medium scale food-scrap composting facility, serving three Vermont counties. Our AGT Compost Hot Skid 250-4R System and working pad upgrade will help accelerate Tamarlane’s composting cycle, reduce labor and increase processing volume on the same footprint.

The VT Clean Energy Development Fund and VT Agency of Agriculture are providing cost-sharing for this project. Recovered thermal energy will heat both a small shop and greenhouse, adjacent to the composting pad.

Catlin Farm – Compost Heat Recovery in Winchendon, Mass.

Jake and Allie Catlin purchased a dairy, on-farm cheese plant and the composting operation in Winchendon in 2017 from long-time owner Dave Smith. Approximately 10,200 cubic yards of manure and bedding are composted annually. The composting operation struggled with wet material, high labor inputs and not having product ready for the spring sales season.

With assistance from a cost-sharing grant from the Massachusetts Clean Energy Center, and funding from the USDA Rural Development Rural Energy for America Program and the MA Department of Agricultural Resources, the Catlin Farmstead purchased a compost heat recovery system from us. As a result, the composting operation has increased its screening yields by 50 percent, enabling it to meet growing demand for its product. (Read more in BioCycle Magazine!)

Pictured above: On September 17, 2020, Jake Catlin hosted a small group tour through the dairy farm, cheese plant and upgraded composting operation. Present to view the compost aeration and heat recovery system  were: John Lebeaux, Massachusetts Commissioner of the Department of Agricultural Resources; MA Senator Anne Gobi; and MA Representative Johnathan Zlotnik. Jake shared that system installed by Agrilab Technologies Inc has sped up their process, improved their screening efficiency and built up their compost inventory.

VT Natural Ag Products – VT Clean Energy Development Fund

The Foster Brothers Farm in Middlebury, VT has been an innovator for decades. They opened the first anaerobic digester in Vermont, started the composting enterprise Vermont Natural Ag Products (VNAP) 25 years ago, and were awarded the U.S. Dairy Sustainability Award in 2016. Foster Brothers’ VNAP is the state’s largest composting facility; it processes dairy, poultry and horse manure, forest product residuals, source-separated food scraps and other biomass into a number of compost and soil products.

VNAP installed compost aeration and heat recovery (CAHR) systems working with Agrilab Technologies Inc. in 2016 and 2017 (click here for Case Study).

Vermont farmers are using Agrilab Technologies innovation to help protect the land and waterways, as seen in this new video produced by the VT Sustainable Jobs Fund and VT Agency of Agriculture:

Our AGT systems accelerate the composting process by optimizing oxygen levels, and also capture and utilize thermal energy – a natural co-product of the active decomposition process – for heating facilities, drying products prior to screening and bagging, and extending full composting operations through the coldest winter weather. 

Hot Skid250R at Collins Hill Farm, Enfield, CT

Administered by Connecticut RC&D’s Connecticut Farm Energy Program, this program was made possible by funds from the Connecticut Department of Energy and Environmental Protection and the U.S. Department of Energy.

Jeff-Dunklee-at-VernMontFarmVern Mont Farm, Vernon VT

AGT installed a Drum Dragon 200 heat recovery system at the Vern Mont Farm in June 2016, connected to an “Enviro-Drum” built by DT-Environmental. The Dunklee family uses the drum to produce low pathogen bedding from the manure of their 750 dairy cows. The computer-controlled exhaust fan on Drum Dragon 200 sends hot humid compost vapor through AGT heat exchanger constantly, producing water in the 120-150F temperature range. The Drum Dragon 200 is designed to capture up to 120,000 Btu/hr, depending on the amount of heat/hot water being used. Click here for Case Study.

Compost Heat Wagon at City Soil and Greenhouse July2015The Compost Heat Wagon 250 at Mattapan Ecovation Center

AGT’s Compost Heat Wagon, a mobile compost aeration and heat recovery system, was setup at an urban commercial compost facility in south Boston in July of 2015. The aerated static pile compost production pad is gravel with simple pipes in channels under the material. The entire system including the compost aeration pad was built in less than a week with no permanent infrastructure. Heat, condensate-water and C02 from compost were provided to the greenhouse keeping it abundant and productive throughout the 2015-16 winter without any additional heating fuels.

UNHpilesUniversity of New Hampshire Organic Dairy Research Farm

The facility started up in 2013 in response for an improved manure management regime. Manure was previously managed as an anaerobic pile that would occasionally be spread on the fields. Although this is a common practice on many dairy farms throughout the region, it posed a significant problem for the university farm, which was trying to become a closed agro-ecosystem. Since the stockpiled manure was not being composted aerobically, significant odors from decomposition were present.

JHFgreenhouseJasper Hill Farm, Vermont

At the end of January 2012, a third medium size Isobar® Heat Exchange System was delivered and installed at Jasper Hill Farm, a small dairy farm and national award-winning farmstead cheese-maker in Greensboro, VT. This farm maintains 40 Ayrshire dairy cows and its new manure handling system is being used in conjunction with a small-scale anaerobic digester, for whey and liquids management. The integrated “Green Machine” incorporates a greenhouse and living filtration system for water purification. The Isobar® system is a core component of the facility heating and maintenance of suitable temperature for the anaerobic liquids management.

Sunset View Farm, New York

Sean and Sandy Quinn, owners of KA Sunset View Farm in Schaghticoke, NY implemented an integrated composting and thermal energy system in late 2010 The farm raises calves and heifers for area dairy farms. The manure and bedding from these calves and heifers are the primary inputs for the composting system. Solid bedded manure from calf hutches and pens are combined with dewatered manure solids in batches and loaded into four negatively aerated composting bays. Sunset View saved $9,200/year in propane and diesel expenses during initial operation.

Diamond Hill Custom Heifers, Vermont

Awarded the Vermont Governor’s Award for Environmental Excellence and Pollution Prevention in 2012, Diamond Hill Custom Heifers Farm has benefited from decreased manure handling costs, decreased heating oil expenses, and increased revenue from sales of high quality compost. This 2000 head calf and heifer farm located in northern Vermont, has presented temperatures great enough to reduce pathogens, destroy weed seeds, and create a product for sale on the farm. Diamond Hill recovered $5,000 in energy costs the first year of implementation and $10,000 a year in recent savings as fuel costs have increased. This integrated compost system provides a new approach to cost effective, solid manure management supplementing or replacing liquid manure systems on dairy and livestock farms.
