Aid No._ref_progr_: SA.41471(2015/X) Purpose_public_aid: Article 25 of Regulation (EC) No 651/2014 of 17 June 2014 declaring certain categories of aid compatible with the internal market in application of Articles 107 and 108 of the Treaty (OJ Urz. EU L 187/1 of 26.06.2014).The pollution of atmospheric air, i.e. smog, generates enormous health, social and economic costs. Studies indicate a link between exposure to air pollution and negative health effects (Clifford et al. 2016, Krzyżanowski 2016). Particularly vulnerable groups are children, people with existing cardiovascular and respiratory diseases, diabetes mellitus, obesity and elderly people. Exposure to air pollution is also associated with increased mortality and reduced life expectancy. Poland has the most polluted air among all Member States of the European Union (Jędrak et al. 2019). One of the reasons is the incineration of high-energy municipal waste in domestic furnaces and boilers, i.e. plastics, rubber products and lacquered furniture. The incineration of this type of waste is a source of emissions of high-toxic compounds: hydrogen cyanide, hydrochloride, nitrogen oxides, hydrogen sulphide, sulphur oxides and carcinogens: aromatic hydrocarbons, chlorinated biphenyls and polychlorinated dibenzodioxins and furans. In Poland, 18 % of all lung cancer cases have their origins in exposure to smog. Experts prove that breathing polluted air and smog increase the risk of leukemia, breast, brain and liver cancer, as well as damage to the nervous system. In our country, typical long-term exposure to PM2.5 is 20-30 µg/m³, and in the most polluted places of southern Poland even more than 40 µg/m³ (WHO 2016).
