| Abstract | The article aims to assess the environmental effects of integrated strate- gies in a municipal waste management system. In particular, the analysis is fo- cused on a waste stream in Palermo, where landfill involves the prompt disposal of the most waste after collection. The current local management system is compared with two integrated waste management alternatives. Both the options predict adopting the available technologies in different ways. In opposition to the current management, which involves energy balance at a loss, the mass and energy balances in hypothetical systems show the capability to obtain energy and material recovery to a substantial extent. Comparison of results of examined strategies allows to draw following conclusions: thermal processing enables 70% increase of recovered energy relating to strategy which includes biological processing of non segregated wastes. Moreover higher efficiency of recycling and segregation al- lows to save energy in connection with avoidance of raw materials usage, but at the same time increases usage of energy for segregation and biological processing. Mentioned relations should mean, that main part in energy saving takes incineration of wastes. introducing of facilities connected with segregation and recovery or recycling of raw material caused following improvements: total level of materials recovery and assignment for composting was 22.3% in strategy B, 27.4% in strategy C, and merely 1.2% in strat- egy A. decrease of need for landfilling area, in relation to current strategy, for neutral wastes of 60% for strategy B and 25% for strategy C. Environmental pressure factors of the management system are assessed depending on the relevant consumption of raw materials and energy, and on the emission of pollutants. The resulting figures reflect the two different integrated management options as being sustainable solutions for achieving an improve- ment in environmental performance, which is based on increasing the value of waste, as an alternative to resources, and the reduction of environmental re- leases. Life Cycle Assessment of municipal waste management systems can be usefully applied to define synthetic indices of environmental impact. These indices could single out possible alternatives in multi-criteria analysis, together with economic and technical parameters. |
