Abstract:
In sustainability assessment of waste treatment scenario the most used economic indicators are: investment costs, operating costs, fuel costs, energy costs and revenues. Cost estimation is relatively crude in solid waste management, without enough available data. Cost planning for waste management has been discussed in various forms: optimization techniques, statistical methods and cost-benefit analyses. In this paper focus is made on the developing of mathematical model with the aim to calculate the economic sustainable indicators (investment costs, operating and maintenance costs, and revenues) of waste treatment scenarios depending on the composition and quantity of waste. The model is based on the analysis of the structure of costs and revenues, and supported by the data available on the field and in the literature. The model is applied to calculate the indicator for the composting and anaerobic digestion, and verified in the case study the city of Niš.
