USE OF COST-EFFECTIVENESS ANALYSIS FOR CHOICE OF MERCURY EMISSION REDUCTION TECHNIQUES IN POLAND


Poland is one of major mercury emitter in Europe to air (11.7 Mg in 2015). Electricity and heat generation from hard coal and lignite is responsible for almost half of this emission. Remaining industrial sectors are source of one third of mercury emission. Stronger expansion of renewable energy could significantly reduce this emission but there are administrative restrictions in the development of wind power. Without change of combusted fuel, further emission reduction from energy sector would be very expensive because fabric filters and activated carbon injection are among the most expensive methods. Measures aimed at preventing emission would be cheaper per kg of mercury e.g. thermo-modernisation of buildings and fuel switching to gas in residential and commercial sectors. Significant mercury flows getting to the environment are also connected with dental practice (amalgam) and use of mercury-containing products (batteries, light sources, other electrical and electronic equipment). Reducing of mercury consumption and more accurate selective waste collection are cheaper than incineration of mercury-contaminated waste and sludge.
