Municipal solid waste treatment by incineration or intergration with electricity generation is being applied in Vietnam. The technological selection for flue gas treatment depends on several factors such as: Vietnam's emission standards, the specification of the solid waste and the incinerator’s configuration. Currently, waste incinerator for electric generation with capacity of 400 tons/day, the flue gas treatment combine of selective non catalytic reduction (SNCR), semi-dry, bag filter and it is totally imported from abroad. For domesticdesigned incinerator with capacity of 100 ton/day, the combination of SNCR and wet process are applied. In the future, it is necessary to improve the solutions for flue gas treatment of domestic-designed incinerator.
