Which option gives the best control strategies for Dioxins and Furans in the flue gas emitted from waste incineration facilities?
- Avoid burning polystyrene (PS) and polyethylene (PE); ensure the furnace temperature above $1000^{\circ} \mathrm{C}$; and use a bag filter for cleaning the flue gas.
- Avoid burning polyvinyl chloride (PVC); quickly cool down the flue gas through the temperature range $400-250^{\circ} \mathrm{C}$; and use an activated carbon treatment for the flue gas.
- Avoid burning food wastes; ensure the furnace temperature above $900 \pm 50^{\circ} \mathrm{C}$; and use an electrostatic precipitator (ESP) for cleaning the flue gas.
- Avoid burning metal bearing waste; ensure the flue gas temperature above $1000^{\circ} \mathrm{C}$; and use a venturi scrubber for cleaning the flue gas.
