In the case of mass burning of MSW, incineration of additional fuel may be necessary, since the calculated calorific value of unprocessed waste may be less than 6.5
MJ/kg. Due to relatively high amounts of produced MSW, the heat energy amount from such incineration could satisfy up to ¼ of total heat energy demands of the Kaunas Heat and Power Plant.
The calculated amount of exhaust gas volume per 1 ton of incinerated waste is 57% higher in the case of HCF incineration, compared to mass burning, at the same time emitting 63% more of HCl and 50% more of SO2. The improved efficiency of household sorting would reduce the volumes and concentration of pollutants in exhaust gases. Calculation of indicators per energy unit showed that mass incineration would release 5.5-6% more exhaust gas, 1-2% more HCl and 40-47% less SO2 in comparison with HCF incineration.
