Regional District of Kootenay Boundary expands feedstock capabilities with Sustainable Generation®
The Regional District of Kootenay Boundary (RDKB) has composted yard and garden waste at the Grand Forks Landfill Facility for more than 25 years using turned windrows. In 2013, as a result of an expanded organics diversion program in the region, residential food waste was added to the windrows. In 2022, RDKB expanded its feedstock capabilities to include biosolids.

THE SG SOLUTION
Meeting Requirements While Producing High-Quality Compost
RDKB intends to produce two distinct Class A end products, including a compost with food scraps and yard waste, and a separate compost product with septage and biosolids. Two bunkers are dedicated to biosolids composting, and three bunkers are devoted to food and yard, and garden waste.
Of significant importance to the RDKB project was the SG BUNKER® System with GORE® Cover capability to comply with the state and local regulatory requirements and resource efficiency:
- Meeting air quality standards for Odor control
- Meeting Vector Attraction Reduction (VAR) requirements;
- Meet Time and Temperature requirements (PFRP) for pathogen reduction
- Produce high-quality finished compost
- Moderate composting processing time
- Low maintenance cost

During heavy storms, composting facilities face increased runoff and leachate.
What our customers are saying…
“The Sustainable Generation® team provided us with outstanding hands-on assistance as we learned to use their system. We retrofit our existing positive air ASP system, which used a compost cap, by upgrading to the SG Mobile® System with GORE® Cover so we could address environmental and community concerns about odors and vector control, and also so we could scale up and expand our composting operation."
Justin Green, Executive Director & Founder Big Reuse
"With disposal and transportation costs increasing with no end in sight, plus an abundance of yard debris from our community, we decided to try biosolids composting at our Wastewater Treatment Plant to reduce our costs and create a Class A product. We went with the SG Mobile® System with GORE® Covers. The ease of operation and the cost savings made this a natural fit. The final product has been a huge hit with the locals who can't get enough Class A compost. We recently doubled the size of our composting operation to keep up with our increasing volumes and demand. This system is easily scalable to meet future demands."
Mike Miller, Public Works Director, City of Florence, Oregon
"We had no composting experience, so conducting a demonstration project with Sustainable Generation® greatly enhanced our understanding of food waste composting and helped us immensely with our subsequent expansion design process. During the selection process, it made a difference that SG's technology was already a proven solution for meeting VOC emission reductions for our San Joaquin Valley Air Pollution Control District."
