municipal solid wastes (msws) vary in terms of quality and quantity, especially their toxic content. the efficient and sound disposal of msws not only needs implementing an integrated management procedure, but also performing a conservative way to reduce the impacts on resources. in the present research, after characterization of msw streams and consideration of disposal methods practiced in si...

Accounting of greenhouse gas (GHG) emissions from waste landfilling is summarized with the focus on processes and technical data for a number of different landfilling technologies: open dump (which was included as the worst-case-scenario), conventional landfills with flares and with energy recovery, and landfills receiving low-organic-carbon waste. The results showed that direct emissions of GH...

Current waste management policies favor biogases (digester gases (DGs) and landfill gases (LFGs)) valorization as it becomes a way for energy politics. However, volatile organic silicon compounds (VOSiCs) contained into DGs/LFGs severely damage combustion engines and endanger the conversion into electricity by power plants, resulting in a high purification level requirement. Assessing treatment...

This paper describes the application of life cycle assessment for evaluating various waste management options in Singapore, a small-island city state. The impact assessment method by SimaPro is carried out for comparing the potential environmental impacts of waste treatment options including landfilling, incineration, recycling, and composting. The inventory data include gases and leachate from...

Sanitary landfill is the common strategy for municipal solid waste management in developing countries. Anaerobic decomposition of disposed wastes in landfill under favorable conditions will lead to the landfill gas (LFG) emissions, considering as emerging air pollutants. The emission of greenhouse gases, including methane, resulting from municipal solid waste disposal and treatment processes ar...

results the modeling results showed that for the gas recovery starting in 2000 and 2015, the power generation would be 2,354 and 830 mw, respectively. in fact, the 15-year difference in gas extraction made a 200% difference. based on the results, from 2000 to 2100, 558 m3/hour of methane would be extracted, which would be equivalent to 2,354 mw energy. subsequently, the emission of 93,721,837 t...

Introduction: Current energy sources are coming to end and one of the main priorities of the country’s management is the energy recovery from renewable energy. Considerable quantity of municipal solid waste (MSW) is one of the most serious urban pollution sources. Impact assessment matrix is a new and fast tool for Environmental Impact Assessment (EIA). Materials and Methods: In this regard, r...

One of the major factors, contributing to the emission of greenhouse gases in the environment is generation of pollutant gases in municipal landfills. As for the design and building of a gas collecting system, it is necessary to properly estimate the amount and type of the landfill emissions. By means of LandGEM model, this study predicts the amount and type of the landfill gases, produced for ...

Background: Large amount of solid waste is annually produced in Kuhdasht city. These waste materials are decomposed by anaerobic microorganisms after burying in disposal site and produce large amounts of gases (mainly methane and carbon dioxide). This study aimed to estimate the gas emission from solid waste disposal of Kuhdasht city using a tool known as LandGEM software. Materials and Method...
