Bozeman, Montana – Gallatin County Montana is moving forward with the design and planning of a new composting facility at the Gallatin County Landfill, with annual capacity to process up to 25,000 tons of biosolids, food waste, yard waste and other organic waste streams.
The Gallatin County composting project is being led by Great West Engineering and recently went through a competitive tendering process to identify the best composting technology for Montana’s unique climate challenges.
The county sought a 6 zone reversing aerated static pile (ASP) system with advanced aeration & recirculation technology to maintain reliable composting operations during Montana’s harsh winters.
After reviewing multiple proposals, Green Mountain Technologies (GMT), with a regional engineering team in Bozeman, was selected as the designer and aeration equipment supplier for the new facility.
Seattle-based GMT brings decades of experience designing and equipping aerated static pile systems across North America, with a proven track record of delivering robust aeration and control systems for municipalities and large-scale composting operations in a wide variety of climate conditions.
The project aligns with statewide momentum of investments in Montana composting infrastructure to alleviate landfill cost pressures and meet environmental goals. Billings, Montana recently began operating a new ASP composting facility (pictured to the left), also designed & equipped by GMT in collaboration with Great West Engineering.
“Our team is honored to support Gallatin County in building a state-of-the-art composting facility in Montana,” said Peter Haun, Bozeman-based Engineer for GMT. “We’re committed to ensuring this project is successful for the community and serves as a model for sustainable organics recycling across the state.”
The new facility will process a mix of food waste, green waste, and biosolids, turning materials that would otherwise be landfilled into compost. Once operational, the facility will reduce landfill dependency, lower greenhouse gas emissions, and create valuable compost products for various uses.
Construction is expected to begin in the spring of 2026, with operations commencing in late 2026.
