Canadian Experience – Hazardous Waste Combustion Prepared for the CEC North American Strategy for Catalyzing Cooperation on Dioxins, Furans and HCB Source Control Workshop April 17-18, 2008 Leon, Guanajuato, Mexico
DRAFT – Page 2 – December 7, 2015 Overview of the Canadian Sector In 2000, 8 hazardous waste incineration facilities identified. In 2006, 12 incinerators identified at 10 facilities, approximately 8 operating. Located in Alberta, Ontario and Quebec Throughput ranges from 416 Mg/yr to 83,000 MG/yr Processes used include rotary kilns with after burners, liquid injection, fixed hearth, 2 chamber, and 2 stage starved. Air pollution control systems range: –None; –Rapid quench, absorber with reagent addition, and scrubber –Spray dryer, powdered activated carbon addition, fabric filter or wet scrubber or electrostatic precipitator –Wet scrubber + re-heat, powdered activated carbon addition, fabric filter In Canada, the responsibility for waste management is shared between the federal government and provincial/ territorial governments. –Jurisdictions often work together through the Canadian Council of Ministers of the Environment (CCME) on waste management issues.

DRAFT – Page 4 – December 7, 2015 Canadian Approach CCME Canada-wide Standards (CWS) for Dioxins and Furans from Waste Incineration (April 2001) –For new or expanding facilities of any size, application of best available pollution prevention and control techniques, such as a waste diversion program, to achieve a maximum concentration 1 in the exhaust gases from the facility as follows: ▪Hazardous Waste Incineration 80 pg ITEQ/m 3 –For existing facilities application of best available pollution prevention and control techniques, to achieve a maximum concentration 1 in the exhaust gases from the facility as follows: ▪Hazardous waste incineration: 80 pg ITEQ/m 3 1 Stack concentrations of dioxins and furans will be corrected to 11% oxygen content
DRAFT – Page 5 – December 7, 2015 Canadian Approach (continued) Jurisdictions are using a variety of tools to implement the CWS: –Ontario - negotiate compliance by amending facility Certificates of Approval (legal instruments) –Alberta – incorporate limits into facility approvals under the Alberta Environmental Protection and Enhancement Act –Quebec – not a signatory to the standards – but committed to act within its area of jurisdiction in a manner consistent with the standards
DRAFT – Page 6 – December 7, 2015 Effectiveness/ Lessons Learned Releases of PCDD/DF have decreased by 95% since Report on progress in achieving the CWS to be delivered To evaluate: –Whether targets have been met –Effectiveness
