Newtrient Comments/Opinions:

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

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 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 structural and civil engineering requirements.
