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
