On September 25 and 26, the Ontario Waste Management Association (OWMA) and the Canadian Chapter of the Solid Waste Association of North America (SWANA) jointly hosted an exciting and informative tour of landfill, bioreactor and waste to energy (WTE) facilities in Eastern Ontario and Quebec. No fewer than 52 OWMA/SWANA members, guests and regional government representatives boarded a bus headed for the Ottawa area to learn about state-of-the-art technology at a number of waste management facilities.

The facilities visited included Plasco Energy Group’s demonstration facility in Ottawa, the City of Ottawa’s Trail Road Landfill site, LaFleche Environmental Group’s waste management facility in Moose Creek, Ontario, and Waste Management’s bioreactor landfill site in Ste Sophie, Quebec.

“The tour showcased some very progressive initiatives being undertaken to advance the management of waste as a resource in Ontario. I found our visit to each project site very informative,” says Waste Services Inc.’s Brian Forrestal.

Plasco Energy Group

The Plasco Energy Group recently unveiled its Plasco Conversion System, which is a thermal process that applies intense heat to waste in an anaerobic environment with no emissions stack. The system converts 100 tonnes of waste per day into synthetic gas that fuels a combustion engine which produces 1400 kWh per year. The byproducts produced include 150 kg of inert slag used in the aggregate industry; 5 kg of sulphur which is reused; and 1.3kg of heavy metals which are disposed of in a landfill. For more information see the August/September edition of this magazine or visitwww.plascoenergygroup.com

City of Ottawa’s Trail Road Landfill

The City of Ottawa’s Trail Road Landfill is home to Energy Ottawa and Integrated Gas Recovery Services’ WTE landfill gas facility which opened in 2007. This facility converts gas from the Trail Road Landfill site into 5 MW of energy to power 5,000 Ottawa homes. The facility will reduce greenhouse gas emissions by up to 180,000 tonnes as well as 40,000 tonnes of carbon dioxide as a result of displaced coal-fired electricity generation.

LaFleche Environmental Group’s Waste Management Facility

La Fleche Environmental Group’s Waste Management Facility includes a bioreactor landfill, a soil remediation facility, and a tire shredding plant. The soil remediation facility allows for the recycling of contaminated soils for reuse and the tire shredding plant recycles used tires for landfill cover and other purposes. The bioreactor is designed to contain and treat all waste and wastewater on site and in an environmentally-friendly manner.

The bioreactor cell is built on impenetrable clay lined with high-tech fabric and drainage stone. As the waste breaks down, the leachate is contained by the liner and clay and flows into a sump system where it is separated into two streams. One stream is re-circulated in the waste and the other stream is treated in a complex water-treatment system. Re-circulation of the leachate allows for anaerobic microbes to decompose the waste in 15 to 20 years, three times as quickly as a traditional landfill.

Waste Management’s Ste Sophie Bioreactor Landfill

The bioreactor landfill at Waste Management’s Ste Sophie site was the first large-scale bioreactor landfill project in Canada and is integral to full-scale research projects implemented to quantify and confirm the benefits of this landfill technology to regulatory agencies, universities, and industry professionals.

The bioreactor technology used at this site accelerates the decomposition of food, paper and organic wastes by managing the moisture content in the landfill. By utilizing these technologies, waste capacity in a landfill could be reduced by 15 to 30 percent, thus decreasing the need for new landfill sites and achieving environmental stability quicker. The Ste Sophie site also provides power from its landfill gas collection and utilization system to the nearby Cascades Mill, thus saving 315 jobs for the community. The conversion of landfill gas into a reliable power source for the Cascades Mill has reduced greenhouse gasses by the equivalent of taking 120,000 cars off the road per year.

The OWMA and SWANA wish to thank all who participated in this tour and a very special thanks to the four sites that opened their doors to their guests and provided very informative tours. The associations look forward to seeing everyone back for subsequent tours. For information on other events and tours please visit www.owma.organdwww.swanaon.org

WASTECON 2007

Solid Waste & Recycling magazine attended WASTECON 2007, a very stiumulating week of workshops, conference sessions and a well-attended trade show. (See photo spread, pages 30-31). This year’s event featured more than 24 hours of technical sessions and discussions. Scott Ginsberg, “The Authority on Approachability” (The Name Tag Guy) kicked off the Opening Breakfast. This year’s keynote speaker, Sandra Cointreau of the World Bank, who discussed the importance of planning for bird flu and other epidemics that could enter various waste streams. Lawrence Lecturer, David Steiner, CEO of Waste Management, Inc. shared his thoughts on industry leadership.

On the last day of the show, SWANA presented its Excellence Awards. Of 15 gold winners, four were from Ontario, including the City of Hamilton and also Halton Region. (See our website or the Up Front section of the last magazine edition for details.)

Mark your calendars! The 2008 WASTECON will be held October 21-23 in Tampa, Florida and we hope to connect with many of our industry friends there.
