Treatment of Flue Gas from MSW Incineration

Despite the fact that incineration is a very interesting MSW management technique, there are a number of issues concerning the environmental impact of this process that need to be carefully considered when evaluating the possibility of 

On the other hand, gaseous pollutant control can be carried out by contacting the gaseous stream with a component (either solid, liquid, or gaseous) that is capable of selectively removing one or more pollutants. One of the most common techniques used for the removal of gaseous pollutants is absorption, mainly for removal of 

In addition co chese, some recenc publications claim that a third class of pollutants, indicated as nanopollutants (essentially made of nm-sized solid particles) should be taken into account. However, scientific evidence available at the moment seems not co be enough to clarify on nanopollutants, their impact on health, and the techniques for their removal from flue gas. 

As indicated earlier, incineration plants usually rely on a combination of the above mentioned devices. Enea and Federambiente (2006) found that different combinations are used in Italy, even though dry and semi-dry techniques are preferred for acid gas control and SNCR is favored over SCR for NOx control, with a large use of activated carbon adsorption for removal of micropollutants.
