Walker services over 10,000 customers nation-wide with seven grease trap and liquid organic waste collection and processing facilities (Toronto, Woodstock, Ottawa, Montreal, Nisku, Calgary and Vancouver), which produce feedstock for renewable energy through anaerobic digestion and biofuel facilities. In Toronto, Ontario, where our largest facility is located, ~130,000 gl per month of FOG is dewatered through a decanting process. The resulting material contain a higher amount of total solids and more energy content on a volumetric basis in comparison to the FOG that arrives to the facility for processing. While opportunities exist to market the material to third parties such as biofuel feedstock traders, we learned that the material that exists our facilities would need to be transported over long distances to arrive to upgrading/treatment facilities.
