In Fig. 3, the value of minimal required calorific value is also presented. It is evident that the calorific value of MSW collected in Kaunas city is lower than the minimum value. The calorific value is decreasing with increasing sorting efficiency. Even in case of Scenario 3, it may not be recommended to incinerate waste without additional fuel. In this perspective, the incineration of HCF obtained in neighbouring regions mixed with MSW collected in Kaunas may be considered.
