Abstract

The problem of choosing a sustainable waste management system is very complex. The complexity is reflected in the large number of waste treatments which vary by technology, efficiency in terms of obtaining energy and utilization of natural resources, possibilities of waste volume reduction, more or less negative impact on the environment, different costs, unequal social acceptability, etc. The selection of a sustainable waste management system is further complicated by the existence of a large number of sustainable development indicators that have been developed in the world and in Serbia, and are used as criteria in sustainability assessment. In addition, there is no one universal model that would assist decision makers in the selection of a sustainable waste management system. Therefore, this doctoral thesis develops a model for the sustainability assessment of waste management scenarios as a decision support system, in order to enable decision makers to choose the sustainable waste management scenarios, with regard to the selected criteria, namely indicators of sustainable development and defined priorities. For the sustainability assessment of defined waste manegement scenarios, this model, uses a multi-criteria analysis method – the Analytical Hierarchy Process. It proposes a set of sustainable development indicators (economic, social and environmental indicators) that can be used for assessing the viability of waste treatment in the Republic of Serbia. This set represents a combination of energy indicators and indicators related to waste. Within the framework of the model for the sustainability assessment, mathematical models are also developed so as to calculate the value of certain economic and social indicators that take into account local economic and social conditions. The verification of the developed model was performed using the case study of sustainability assessment of the developed waste management scenarios in the City of Niš, while the validation of the model was performed using the case study of sustainability assessment of waste management scenarios in the City of Sofia.
