Grand Forks, BC - Grand Forks Compost Facility

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, which has not previously included septage or biosolids, but they are an emerging feedstock for this facility.

Meeting Requirements While Producing High-Quality Compost

RDKB chose a 5 SG BUNKER® System with 5 GORE® Covers as its solution for their upgrade. The Regional District 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 would be dedicated to biosolids composting and three bunkers would be 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:

  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. Moderate composting processing time

  6. Low maintenance cost
