Scaling to Meet Expanded Organics Diversion Programs in Ontario
All Treat Farms, operated by Walker Environmental Group Inc., has processed yard waste, SSO, and AD Digestate at its Arthur Compost site for more than 15 years using a 32 SG BUNKER@ System with GORE® Cover. In 2021, as a result of an expanded organics diversion program in the region, Walker All Treat Farms needed to increase capacity without increasing the footprint of the facility.

THE SG SOLUTION
Meeting Requirements While Producing High-Quality Compost
To maximize the All Treat Farms’ capacity within the existing footprint, an upgrade to a 32 SG BUNKER® System was decidedly the best choice. Featuring SG COMPOST CONTROL™ System, the facility will process the expanded feedstock quantity while continuing to meet environmental regulations.
Of significant importance to the All Treat Farms project was the SG BUNKER® System’s capability to comply with the state and local regulatory requirements and resource efficiency:
1. Meeting air quality standards for Odor control
2. Meeting Vector Attraction Reduction (VAR) requirements;
3. Meet Time and Temperature requirements (PFRP) for pathogen reduction
4. Produce high-quality finished compost
5. Clear Separation of Leachate from Stormwater
6. Low Power Consumption
7. Moisture Management
8. Lowest Total Cost of Ownership over the life of the facility

Why Smart Composting Facility Operators Keep Stormwater and Leachate Separate
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."
