SV COMPOSTER(tm)
Municipal Solid Waste Composting
CUSTOMER PROFILE
West Yellowstone/Hebgen Basin Solid Waste District
CLIENT NEEDS
The District issued an RFP seeking a single vendor to provide a turn-key MSW composting facility that would:
Process up to 40 tons/day of MSW waste per year in a snowy and cold winter climate;
Require few operational staff and a small and footprint; and,
Provide in-vessel composting of mechanically sorted MSW.
THE SOLUTION
ECS' teamed up with Montana based, DA Construction, to build an enclosed compost facility featuring an in-vessel "tunnel" composting system: the SV Composter.
Pre-Processing: A wet mill homogenizes the floor sorted MSW, mechanically reducing paper and other feedstocks without shredding or grinding. The wet mill includes a coarse trommel screen section that removes 3"+ physical contaminants. Fines passing through the screen are conveyed to a heavy-duty mixer that blends them with biosolids and bulking agents.
SV Composter: Primary composting takes place in seven low-headspace vessels that feature a sophisticated aeration design and the CompTroller™ automated process control system. These concrete and stainless steel vessels can hold up-to 175 yd3 each. The raw mixes is moved from the mixer and piled in the vessels with a specialized conveyor system. This vessel loading system reduces labor, uses vessel space more efficiently, and minimizes worker exposure to feedstocks.
 Product Curing and Refining: An ECS Aeration Control and Monitoring System provides for an ASP curing process following primary composting in-vessel. After product curing, front-end loaders move the compost to the product refining area. In-feed hoppers evenly metered the product over a vibrating screen and then to an air-classification de-stoner to remove physical contaminants in preparation for markets. The compost will be used for landscaping public and private projects within the West Yellowstone/Hebgen Basin Solid Waste District.
