GHD supported the City in developing their Source Separated Organics Program to divert organics out of landfill waste and turn them into compost. The Organics are also turned into RNG to heat City buildings and fuel their waste collection vehicles.
GHD prepared a detailed Feasibility Study for the Dufferin RNG project, providing key findings and requirements for the construction of the first biogas upgrading facility. GHD also provided contract and procurement support, conceptual and detailed design and engineering services, permitting and approvals support along with construction and commissioning support and troubleshooting. This ongoing work has ensured continued integration of the biomethane system with the City’s Anaerobic Digesters and Enbridge's injection station during the construction, commissioning and operations phases.
In 2021, GHD, on behalf on Enbridge, prepared a detailed Feasibility Study, led the environmental approvals and provided contract and procurement support, detailed design and engineering services for the Disco Road Organics Processing Facility RNG project, developing the City’s second Organics to RNG project. This led to Enbridge retaining GHD to take on full engineering, procurement and construction (EPC) services and permitting on the Disco Road Organics Processing Facility RNG project. Once completed, this facility is expected to produce a constant source of carbon-neutral RNG from organic waste to support the City’s decarbonisation efforts.
Based on the RNG project successes in Toronto, the City continues to investigate technology to beneficially utilize landfill gas. The Green Lane Landfill facility is considering an upgrade to the landfill gas and utilization system on-site in the coming years.
