Abstract

The actual attention to the necessity to improve innovative systems of energy recovery, together with the global increase of wastes, both from the qualitative (as concerns content of parts that can be reutilized) and from the quantitative point of view, leads to the actual need of systems of waste disposal/treatment that allow a volume reduction and, at the same time, an energy and materials recovery. The incineration is a system that offers both the mentioned opportunities: volume reduction and energy recovery. In fact the incineration is a rather developed system for the wastes elimination based on their energetic characteristics; in these years we have assisted to a considerable improvement both as concerns the efficiency of the plant, and also the environmental impact containment. The aim of this work was to analyze the MSW (municipal solid waste) incineration plant currently under construction in the province of Turin (Piedmont, North Italy), especially its potential for energy recovery, and the consequent environmental effects. We analyzed two kinds of energy recovery: electric energy (electrical configuration) only, and both electric and thermal energy (cogenerative configuration), in this case with a different connection hypothesis to the district heating network. After we had evaluated the potential of the incinerator and considered local demographic, energy and urban planning effects, we assumed different possible connections to the district heating network. We computed the local and global environmental balances based on the characteristics of the flue gas emitted from the stack, taking into consideration the emissions avoided by the substituted sources. The global-scale results provided relevant information on the carbon dioxide emissions parameter. The results on the local scale were used as reference values for the implementation of a Gaussian model (Aermod) that allows evaluation of the actual concentration of the pollutants released into the atmosphere. From the economic point of view we performed a comparison between the net actual value of the economic financial plan of the incineration plant and the net actual value of the externalities (calculated on local and global scale).
