![]() An impeller spins inside each of these Italian-made machines. Source separated organics from the tipping floor, typically containing 12 to 14 percent contaminants, are processed, 16.5 tons at a time, through one of three BTA Waste Pulpers. Similar to the original Dufferin facility, SSO is preprocessed through the BTA™ Hydromechanical Pretreatment System patented by Germany’s BTA International and licensed in Canada and the United States by CCI. Centrifugal force opens the bags contaminants separate into light and heavy fractions. The organics, arriving in plastic bags and typically containing 12 to 14 percentĬontaminants, are processed through one of three BTA Waste Pulpers. While the fundamental process steps are similar, AECOM and operators Veolia North America and CCI BioEnergy Inc., “had the ability to build in all the good knowledge gained” at the pilot plant, says Carlyle Khan, the City of Toronto’s Solid Waste Management Services’ Director of Infrastructure Development and Asset Management. The Disco Road project took advantage of lessons learned at the Dufferin site. With a municipal election last October, and the onset of winter, the City decided to schedule the official opening this spring, when the weather has improved and the new City Council is sitting. Following that step, the City of Toronto’s chief contractor, AECOM Inc., began implementation of operations, including establishment of biological equilibrium in the anaerobic digestion system, as well as optimizing and fine-tuning the wastewater treatment process, biofilter odor control system and biogas flare. The $74 million Disco Road AD plant completed commissioning of its design and construction activities last summer. ![]() When the expansion at Dufferin is completed, the two facilities combined will be able to process 143,300 tons of feedstock annually and Disco Road will produce enough electricity to be nearly independent of the provincial grid. The Dufferin plant opened as a pilot project 12 years ago, with capacity to process about 27,500 tons per year of SSO. Planning is underway to revamp and more than double the capacity of the city’s original SSO digester, the Dufferin Organics Processing Facility. Electricity generation and heat recovery will be added by spring of 2016. Known as the Disco Road Organics Processing Facility, it is capable of handling up to about 83,000 tons of source separated organics (SSO) annually. This spring, a ribbon cutting will mark the official opening of the City’s second organics processing facility, with pretreatment followed by anaerobic digestion (AD). Toronto, Ontario, Canada’s largest city, is taking major steps to expand its already successful collection and processing of residential source separated organic wastes. The City of Toronto’s new anaerobic digester, the Disco Road Organics Processing Facility, has capacity to process about 83,000 tons/year of residential source separated organics (SSO).
