AIR POLLUTION IMPACT ASSESSMENT OF ALTERNATIVE FUEL COMBUSTION PLANT IN COMPARISON TO THE CONVENTIONAL HEATING PLANT
According to the Voivodship Waste Management Plans adopted in 2017, practically the total stream of mixed municipal solid waste (approx. 10 million Mg) is directed to more than 150 installations of mechanical-biological processing (MBT). In these installations approximately 3.5 million Mg of alternative fuels (often named as RDF - Refuse Derived Fuel) are produced. Only about 1 million Mg is combusted in cement plants and the rest is currently stored. RDF has a status of waste and must be incinerated in special incinerators. It is planned to build dozens of such installations, but this causes many social protests.
In a lecture the emissions from the alternative fuel incineration plant with a similarly rated 30 MW grate boiler fired by hard coal WR-25 were compared. It has been shown that actual emissions from RDF incineration are considerably lower than during coal combustion, and the impact of the installation is considerably lower than that of conventional heating plants.
