Essex-Windsor Regional Landfill (EWRL) is owned by the County of Essex and is operated by the Essex Windsor Solid Waste Authority (EWSWA). The site officially opened in July of 1997 and has a capacity of 12 million cubic metres of landfill volume. It is expected to close between 2027 and 2034, depending on future fill rates.
In 2001, Comcor was retained by the EWSWA to design and construct a temporary landfill gas collection and flaring system at the EWRL in order to control odours from the leachate collection system manholes. The system involved a blower system providing vacuum to a number of manholes with the landfill gas directed to a candlestick flare for destruction. During 2008, Comcor (through the IGRS partnership) was retained to design, supervise construction and commission a major expansion to the landfill gas collection system infrastructure with the addition of vertical extraction wells within the waste. This project included the installation and connection of twenty-three (23) landfill gas extraction wells and a portion of the landfill gas collection header and lateral piping.
During 2009, Comcor (through the IGRS partnership), upgraded the system to include a fully enclosed landfill gas flare (to replace the candlestick flare) in order to secure carbon credits. IGRS secured a 5-year verified emission reduction purchase and sale agreement for 50,000 tonnes of CO2e per year. Revenues from the sale of emission reductions paid for all costs associated with designing and building the facility as well as operating costs. Comcor continues to operate and maintain the facility on behalf of IGRS for the EWSWA.
