Compost Powered Heat

About the Company:

Agrilab Technologies, Inc. (AGT) is a Vermont-based company with a proprietary compost aeration and heat recovery (CAHR) technology that has been successfully used on livestock farms since 2006. Other products include aeration and drying systems, nutrient recovery, and specialized farm equipment. The team provides design, development, installation and operating support services to complement its line of modular equipment. The products and services save farms labor, space, and energy while reducing odors and producing compost products. The company’s clients include dairy farms, commercial and municipal composters, and institutions.

About the Solution:

The AGT Mini system brings Agrilab Technologies Inc.'s suite of aeration, heat recovery, and control technology into a configurable package for smaller compost volumes. The AGT Mini system is a compact solution for smaller compost operations. The Mini System shares the features of our larger products but in a smaller, modular package that requires some on-site assembly. With the goal of minimizing cost without sacrificing quality.

Standard features include the industrial control package, speed adjustable blower, and monitoring of temperature, oxygen, and flow rates. A standard system can be piped to a single compost zone, or multiple zones with manual valves. Negative aeration offers the opportunity to use heat directly from the hot compost exhaust in a biofilter growing bed. Air-to-water heat exchangers, and automated valve packages are engineered to be easily integrated with the base model.

The Mini System is available in 3” and 4” pipe sizes, with up to five automated zones, to aerate compost volumes from 30 to 400 cubic yards.

Newtrient Comments/Opinions:

Agrilab Technologies Inc. offers an innovative solution for capturing heat, carbon dioxide, and ammonia from aerated, turned, or static compost piles, suitable for integration with existing greenhouse or composting operations. This technology is already operational on several dairy farms in Vermont, New Hampshire, and Massachusetts.

Newtrient conducted a review of this technology in late 2021, supported by USDA NRCS Conservation Innovation Grant funding. Data from a commercial installation at Vermont Natural Ag Products, Inc. (VNAP), a subsidiary of Foster Brothers Farm, Inc. in Middlebury, Vermont, is available as an Expert Evaluation report on this page. Sampling and analysis were conducted by the University of Vermont as part of the grant.

Additionally, Agrilab Technologies Inc. has received USDA REAP funding for projects in three states. They specialize in offering aeration-only units to farmers and other clients, with their compost aeration and heat recovery (CAHR) systems featuring a renewable energy component. These systems have proven effective in improving manure management, saving labor and space, and producing end-products with reduced pathogens and weed seeds. Agrilab Technologies Inc.'s aeration-only systems are eligible for NRCS 317 Practice - Compost System cost-sharing. They collaborate closely with clients and USDA staff during the conceptual design stage, addressing process, structural, and civil engineering requirements.
