Management of municipal solid wastes is one of the important environmental problems because of increasing population and developing industrialization in our country. Besides, there is a need to seek alternative energy sources due to rapid consumption of conventional energy sources. Landfilling is still the most common solid waste disposal method in the world and generated landfill gas consists of significant amount of methane that could be used for energy generation. In this study, it is aimed to model the landfill gas generation at different waste composition scenarios at Afyonkarahisar Sanitary Landfill Site. LandGEM and IPCC 2006 models were used for estimating the landfill gas amounts and determining energy content of the gas in the site. According to model results, methane generation rate (k) and methane generation potential (L0) were 1.56 1/year and 44.12 m3/Mg, respectively. When organic wastes are stored in the site separately, 40% higher methane gas generation could be obtained. With separation of ash, 24% increase could be obtained. In addition, service life of the lots increased. On the other hand, if recyclable wastes were separated from the waste for storage, methane gas generation was approximately the same as the base case due to small percentage of recyclables in the waste. Greenhouse gas (GHG) emission evaluations showed that only organic waste storage scenario provides 0.6% reduction in GHG emissions in Turkey.

Municipal solid waste management with cost minimization and emission control objectives
Mohsenızadeh, Melıka; Kentel Erdoğan, Elçin; Tural, Mustafa Kemal (null; 2017-10-14)
Proper management of municipal solid waste (MSW) has been a crucial aspect of every society due to its social, environmental, and economic impacts. Operations research techniques have frequently focused on cost minimization objectives in locational planning of municipal solid waste management (MSWM) systems. However, transportation constitutes an integral part of this system producing a considerable amount of greenhouse gas (GHG) emissions. Therefore, sustainable management of this system with GHG emissions...
Investigation of fuel values and combustion characteristics of RDF samples
Sever Akdağ, Ayşe; Sanin, Faika Dilek; Department of Environmental Engineering (2014)
Municipal solid waste (MSW) is an unavoidable by-product of human activities. The generation of MSW tends to increase with the growing population and the economic development of the society. Landfilling is one of the most common disposal methods for MSW in the world. However, there are numerous disadvantages of landfills including the potential to create air, soil and water pollution. Also, many valuable resources are wasted when waste is landfilled. Furthermore, many countries have established rules to lim...
Assessment of PCB contamination, the potential for in situ microbial dechlorination and natural attenuation in an urban watershed at the East Coast of the United States
Kaya, Devrim; Sowers, Kevin R.; Demirtepe, Hale; Stiell, Brian; Baker, Joel E.; İmamoğlu, İpek; Kjellerup, Birthe (Elsevier BV, 2019-09-15)
Sediment contamination is a major environmental issue in many urban watersheds and coastal areas due to the potential toxic effects of contaminants on biota and human health. Characterizing and delineating areas of sediment contamination and toxicity are important goals of coastal resource management in terms of ecological and economical perspectives. Core and surficial sediment samples were collected from an industrialized urban watershed at the East Coast of the United Stated and analyzed to evaluate the ...

Water resources globally are affected by a complex mixture of stressors resulting from a range of drivers, including urban and agricultural land use, hydropower generation and climate change. Understanding how stressors interfere and impact upon ecological status and ecosystem services is essential for developing effective River Basin Management Plans and shaping future environmental policy. This paper details the nature of these problems for Europe's water resources and the need to find solutions at a rang...
Management of disalination brine in Qatar and the GCC countries
Sezer, Nurettin; Evis, Zafer; Koç, Muammer (null; 2017-06-30)
Reliance on desalinated water has been ever-increasing due to increase in population and over-exploitation of natural fresh water resources. Desalination process produces fresh water at the expense of natural environment. Desalination waste, known as brine, is the major pollutant of seawater. However, there has not been a unique brine management technology that could work effectively everywhere. Therefore, effective processes are required to treat and manage the brine specific to the desalination plants. In...
