Arthur, Ontario - Walker All Treat Farms

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 Heap GORE® Cover System. In 2021, as the 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.

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’s advanced compost control system and 32 GORE® Covers, the facility will process the expanded feedstock quantity while continuing to meet environmental regulations.

Unique to the Sustainable Generation Compost Control System are features to make the operation of the facility run smoother while optimizing the process control for the highest quality output material.

Of significant importance to the All Treat Farms project was the SG BUNKER® System with GORE® Cover 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 finish 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
