Is a further reduction of the emission limit value for SOx in waste incinerators meaningful from an LCA perspective?

From a life-cycle perspective, a system reducing the SOx concentration from 1500 to the current emission limit value (ELV) of 50 mg/Nm³ in the flue gas of a hazardous waste incinerator, significantly reduces the overall environmental impact of the incinerator in the impact categories acidification and photochemical oxidation, at the expense of relatively limited impacts in other impact categories. In case the ELV for SOx would be lowered from 50 to 25 mg SOx/Nm³, the existing installation has to be optimised or additional equipment has to be added. It is shown that in this case, the environmental impact of the incinerator is further reduced in the impact categories acidification and photochemical oxidation, but at the expense of considerable impacts in other impact categories, mainly global warming and abiotic resource depletion.
