Client Needs

Pope Douglas began collecting source separated organics in 2017.  As they expanded collections and ramped up capacity, they needed a composting solution that would work well in their climate.  The system needed to capture and control leachate, work in very cold weather, and minimize odor.  In addition, they required a system that could expand over time to meet the forecasted organics growth.  They developed the Glacial Ridge  Compost Facility, which will process up to 15,000 Tons/yr from Douglas, Pope, Grant, Stevens and Otter Tail counties.

ECS Solution

ECS developed a phased solution centered around high aeration rates and automated temperature control.  Phase 1A include four positively aerated static pile (ASP) zones to process ~2,500TPY using trench style aeration floors to uniformly distribute air and capture leachate.  Phase 1B delivers an additional 4 zones (8 total).  Phase 2 adds an additional 8 zones and adds ductwork to enable reversing + recirculating aeration.  This will help maintain low odor and quick throughput even as the volume of material on site increases.

We worked with ECS to develop a system that is responsive to changing weather conditions and can reduce some of the operational guess work, labor, and equipment requirements compared to a traditional windrow composting process. Nathan Reinbold Environmental Coordinator
