Impact Of The Municipal Solid Waste Incineration Plant In Warsaw On Air Quality, Robert Oleniacz

Robert Oleniacz

The only Polish municipal solid waste (MSW) incinerator has been operating within the Municipal Solid Waste Disposal Plant in Warsaw since 2000. In the paper selected results of the air quality impact assessment for this incinerator during an operating period of one year (2008) are presented. With respect to the incinerated waste amounts and emission levels, the analysed period can be considered typical for this facility. Assessment of the air quality impact was carried out by assessing air pollutant emissions in reference to the applicable emission limit values and by modeling atmospheric dispersion of these pollutants. It has been found …

Assessment Of The Impact Of Municipal Waste Incineration Plants On Air Quality And The Possibilities Of Its Reduction, Robert Oleniacz

Robert Oleniacz

The planned construction of new municipal waste incineration plants over the next few years in Poland results in protests of local communities, which arise mainly from fear of an increase in the air pollution in its vicinity. These protests extend the investment process and hinder the selection of incineration plant location, but on the other hand they necessitate the use of more efficient solutions to reduce their impact on the air quality.This paper characterizes the world's most widely used technology for municipal solid waste incineration (MSWI) and assesses the possible maximum impact on the air quality of an exemplary MSWI …

Wpływ Dużej Spalarni Odpadów Przemysłowych I Niebezpiecznych Na Jakość Powietrza, Robert Oleniacz, Lidia Rusztowicz

Robert Oleniacz

Waste incineration causes unavoidable pollutant emissions to atmosphere and thus negative impact on air quality, but scale of the influence is often exaggerated. In the paper computation results of the atmospheric dispersion of pollutants were presented for one of the largest industrial and hazardous waste incineration plant existing in Poland (processing capacity: 3 ton per hour). These results confirm the fact that the incinerator meets the requirements of best available techniques (BAT) for the waste incineration and its impact on air quality is relatively small. This effect is caused mainly by proper operation of the rotary kiln incinerator, high efficiency …
