Construction of the Municipal Solid Waste Incineration (MSWI) plant is considered optimal in the Programme of Management of Solid Waste in Krakow as well as in proposed scenarios of Municipal Waste Management. Evaluation of impact of the incineration plant with a capacity of 255000 tons per year on air quality in Krakow is presented in this work. The evaluation is based on assumption that air pollutant emissions from the incinerator will be at the highest allowed level resulting from emission limit values for waste incineration plants with operation time each of two planned lines 7500 hours per year. Calculation results support the thesis that building the incineration plant of this size will not cause significant worsening of air quality in Krakow independently of final localization. It is recommended, however, not to place the MSWI plant near densely populated areas. English title: Assessment of influence of the planned municipal waste incineration plant on air quality in Krakow.
