City of Kamloops

The City of Kamloops (CoK) sought opportunities to develop and implement management options for biosolids and other organic materials in support of their Liquid Waste Management Plan and the Sustainable Kamloops Plan. For several years, the CoK managed leaf and yard waste and wood waste through composting at its Cinnamon Ridge facility. In the early 2000s, the CoK identified composting as an opportunity to also beneficially manage biosolids. The Sustainable Kamloops Plan, adopted in 2010, was revisited in 2013 to provide a status update on the key components of the plan, one of which is solid waste. One of the measures of success in the Plan was the reduction in solid waste to landfill to 0.3 tonnes per capita by 2020; in 2013 the CoK was at 0.574 tonnes per capita. As organic waste typically comprises approximately 30-40% of the waste stream, it was recognized that additional practices would be required to help the CoK achieve its goal. The CoK engaged SYLVIS to prepare an assessment of collection options for organics including leaf and yard waste and source-separated organics, as well as an assessment of composting options to accommodate increasing volumes of organics and biosolids requiring management.

SYLVIS conducted site visits and extensive client engagement to develop and refine a framework for assessing the feasibility of various collection and composting options and the adherence of those options with the CoK’s overall values and objectives. Options were assessed based on environmental, social, economic, technical, and market potential evaluation categories and criteria. Evaluation criteria were developed in consultation with CoK staff.

Based on a review of organics and biosolids volumes, available composting technologies, and existing and potential CoK resources, SYLVIS provided the CoK with a comprehensive and detailed assessment of various collection and composting options at two potential sites. The recommended strategies for collection and composting will be carried forward by the CoK for further assessment and potential implementation.
