Green Mountain Technologies Horse Manure Composting System

Green Mountain Technologies, Inc (GMT)– $388,310 – Although composting is not new, the in-vessel system is a closed system reducing variability of environmental factors impacting composting success. The vendor offers this as a turnkey operation and provides ongoing management support which reduces farm operator time, labor requirements and potential error. GMT proposed two individual projects for in-vessel composting:  The first is a small composter at a horse rescue facility in Howard County where nutrients and by-products will be reduced by 50 percent. GMT is in discussion to market this compost to vendors who sell planting medium for nursery production. The second project is larger and will be implemented on a dairy farm in Frederick County that also will process the offal from its turkey production and processing facility. The agricultural operation is owned and managed by Eugene Iager, who is exploring the use of the compost for dairy bedding and opportunities for marketing it. GMT operates out of Seattle, Wash., and they will use web-enabled controllers and probes to monitor temperatures and manage the composter remotely when not on site.

“Green Mountain Technologies is honored to have two projects selected by MDA. We realize that the agricultural industry must be given waste management options that are not only environmentally sustainable but also financially sustainable,” said GMT Agricultural Sales Specialist Mollie Bogardus. “We believe in furthering the market channels for the value added products created through quality composting of the waste from dairies, equine facilities and poultry sites. These grants will provide Maryland farms examples of successful composting operations.”

In January 2014, MDA issued a Request for Proposals for demonstration projects with proven and innovative technologies that manage agricultural manure and on-farm generated waste in a manner that improves its utility as a fertilizer, changes its form or function for alternative uses, or produces energy or other marketable products. The overall outcome of the technology will result in reduction of nitrogen and/or phosphorus movement to surface waters associated with animal manure produced on farms in Maryland.

Maryland’s nutrient management regulations govern the amount, timing, and placement of crop nutrients—including manure and other organic nutrient sources—on agricultural land to prevent excess nutrients from impacting waterways. To help poultry and livestock producers comply with the regulations, Maryland is supporting and investing in alternative uses for manure such as fertilizer manufacturing, composting and manure-to-energy projects, and the development of new products that add value to improve farm viability.

MDA received eight bids, which were reviewed by a six-member technical review subcommittee. The subcommittee represented diverse skill sets and backgrounds and its members were chosen from the 20-member Advisory Committee for the Animal Waste Technology Fund. Three of the recommended projects were approved by the Board of Public Works on Wednesday, August 13. An award for one additional project is expected to be made this fall, following Board of Public Works approval.
