What's New

On April 13, 2022, the CRD Board approved next steps for a pilot program that will evaluate potential thermal resource recovery options for the Class A biosolids produced through wastewater treatment.

Given the complex nature of thermal technology, the Board directed staff to explore the possibility of a long-term beneficial use option for the region’s biosolids through pilot studies at existing processing facilities in February 2021.

After a detailed procurement process, CRD staff have now engaged three North American vendors for this research program and expect to have data that will inform planning for the long-term management of this material in early 2023.

The CRD’s long-term biosolids management planning process will explore a broad range of beneficial use options and markets, including gasification and land application, as directed by the Province. Public consultation will also be a key component of this planning process ahead of the CRD’s submission of a final plan to the Province in 2024.


The biosolids produced at the CRD's Residuals Treatment Facility must be beneficially used to meet the regulatory requirements outlined by the Province.

The CRD has procured services for the beneficial use of this waste stream with British Columbia’s lower mainland-based cement industry as an alternative fuel, helping reduce their reliance on non-renewable fuels to power their facilities. Using biosolids to power the manufacturing of cement reduces greenhouse gas emissions in alignment with the Province’s CleanBC plan to use clean energy to power BC’s industrial economy.

The CRD Biosolids Beneficial Use Strategy (Definitive Plan), complete with the First Nations and public engagement reports, was received by the CRD Board at their meeting on June 12, 2019. The final report was provided to the Ministry of Environment & Climate Change Strategy in June 2019.

The CRD’s short-term management plan, including this contingency plan, has been approved by the Ministry of Environment and Climate Change.

With Provincial approval and these beneficial use contracts now in place, the CRD has started developing a long-term management plan for biosolids that will include public consultation on the full spectrum of options permitted by Provincial regulations.

Public Feedback

Public engagement is a key part of developing the CRD's overall biosolids management strategy. The CRD collected feedback on the proposed short-term solution ahead of submitting its definitive plan to the Province. A summary of the feedback received can be viewed in Appendix M of the Definitive Plan.
