Sustainability assessment of municipal solid waste management requires a holistic approach in evaluating the impacts of current technology and processes. In this study, the sustainability analysis of the Municipal Solid Waste (MSW) incineration plant in Baltimore city was performed to determine its environmental, economic, and social impacts. The city’s major waste-to-energy generation plant has benefitted the city of Baltimore since inception till date in terms of waste processing, resulting in electricity and steam production for more than 40,000 homes and over 200 businesses. The life cycle impact of the incineration plant was analyzed using the Simapro life cycle assessment (LCA) software with the Building for Environmental and Economic Sustainability (BEES) database for correlation. The results obtained upon analysis show larger values of Global Warming Potential and eutrophication potential as 6.46 × 108 Gg of CO2 equivalence and 2.27 × 106 Gg N equivalence, respectively. These values resulted from the higher amount of fossil CO2 and NOx emitted from the plant. The acidification potential of 1.66 × 1017 H+ mmole eq resulted from the SO2 emitted by the incineration plant. The incineration plant exceeded the limitations set by the Environmental Protection Agency (EPA) on NOx (150 ppm), which is detrimental to the well-being of people as shown by this study. Installing an improved processing technology such as a Selected Catalytic Reactor (SCR) can drastically reduce the NOx emission to 45 ppm. Life Cycle Assessment was confirmed suitable in evaluating the environmental impacts of the MSW-to-energy treatment approach.

Health and safety have been the major concerns in waste management. Waste must be managed in a way that minimizes risk to human health. Environmental concerns over the management and disposal of waste can be divided into two major areas: conservation of resources and pollution of the environment. Integrated Waste Management (IWM) systems combine waste streams, waste collection, treatment and disposal methods, with the objective of achieving environmental benefits, economic optimization and societal acceptability. Integrated waste management using Life Cycle Assessment (LCA) attempts to offer the most benign options for waste management. LCA is a compilation and evaluation of the inputs, the outputs and the potential environmental impacts of a product system throughout its life cycle. It can be successfully applied to municipal solid waste management systems to identify the overall environmental burdens and to assess the potential environmental impacts. This paper deals with the LCA of the two waste management options for final disposal of municipal waste, landfilling (landfill without landfill gas collection or leachate collection) and sanitary landfilling (landfill with landfill gas collection and recovery and leachate collection and treatments) analyzed for town Sombor, Serbia. The research is conducted with the use of the Software Package IWM-2. The indicators which are used in the assessment are air and water emissions of toxic compounds. The results indicated that waste disposal practice has a significant effect on the emission of the toxic components and environmental burdens. Sanitary landfilling of municipal solid waste significantly reduces toxic emission and negative influence on the environment.

Abstract The research focuses on complex comparative evaluation of environmental efficiency of Municipal Solid Waste (MSW) treatment scenarios that can be implemented in St. Petersburg and Leningradskaya oblast’. Three scenarios were modelled that technically and economically meet the regional needs. The scenarios imply the following systems: 1) sorting, Mechanical-Biological Treatment (MBT), landfilling; 2) sorting, MBT, Waste-to-Energy (WTE), landfilling; 3) sorting, MBT, Refuse Derived Fuel (RDF) for cement industry, landfilling. In comparison, the “zero” scenario implying landfilling untreated waste was modelled. A Life Cycle Assessment based approach was proposed, which allows comparing scenarios through converting heterogeneous impact categories to a single monetary index. The highest damage reduction (by 60-70% in comparison with the “zero” scenario) was shown in the complex scenarios, including both MBT and energy recovery. 40, 42 and 47% of the total damage in scenarios 1, 2, 3 accordingly is associated with MBT product landfilling. The results show that the main benefit of complex treatment cannot be fully realized without separate collection of food waste. In this situation the most environmentally soundable scenario comprises recyclables separation and subsequent WTE treatment of all the rest with the exception of some non-combustibles.
