The paper presents some problems related to the environmental impact of waste incineration plants with particular emphasis on the impact on air quality and the assessment of this impact carried out for newly built incinerators. Methodology for the calculation of emissions for new plants based on emission standards was proposed. It has been shown that waste incineration plants complying with emission limit values to a negligible extent affect the air quality, especially in the case of units with small capacity.

In the case of polychlorinated dibenzo-p-dioxins and dibenzofurans, due to lack of permissible levels in the air, it was found that air concentrations resulting from their emissions occurring at the level of the emission limit value (0,1 ngTEQ/Nm3) are much lower than the background of these substances in urban and industrial agglomerations, especially during the heating season.
