Different solid waste management system scenarios were developed and compared for the Municipal Solid Waste Management System of Ankara by using the life cycle assessment (LCA) methodology. The solid waste management methods considered in the scenarios were collection and transportation of wastes, source reduction, Material Recovery Facility (MRF)/Transfer Stations (TS), incineration, anaerobic digestion and landfilling. The goal of the study was to determine the most environmentally friendly option of MSWM system for Ankara. The functional unit of the study was the amount of solid waste generated in the system area of concern, which are the districts of Ankara. The life cycle inventory analysis was carried out by IWM Model-1. The inputs and outputs of each management stage were defined and the inventory emissions calculated by the model were classified in to impact categories; non-renewable energy sources exhausting potential, final solid waste as hazardous and nonhazardous, global warming, acidification, eutrophication and human toxicity. The impacts were quantified with the weighing factors of each category to develop the environmental profiles of each scenario. In most of the categories, Source Reduction Scenario was found to be the most feasible management method, except the global warming category. The lowest contribution to G-AT was calculated for the anaerobic digestion process. In the interpretation and improvement assessment stage, the results were further evaluated and recommendations were made to improve the current solid waste management system of Ankara.

In developing countries, good-quality water is contaminated due to the disposal of untreated municipal and industrial wastewater (WW) into natural water reservoirs. Most of the wastewater is not treated properly according to international standards, and usually is disposed of and/or utilized for irrigation without appropriate treatment. The main hurdles in providing wastewater treatment (WWT) in developing countries include high costs, and the poor design, installation, and operation of conventional WWT sys...
Composite landfill liner design with Ankara clay, Turkey
Met, İlker; Akgün, Haluk (Springer Science and Business Media LLC, 2005-04-01)
This study presents an overview of the geotechnical properties of the clayey soils, referred to as "Ankara clay", at two sites of the Ankara region in an attempt to design a landfill profile composed of a high density polyethylene (HDPE) geomembrane/clay composite liner through the Hydrologic Evaluation of Landfill Performance (HELP) model and the Water Balance Method. The geotechnical properties of the landfill layers along with the water balance factors (i.e., evapotranspiration, precipitation, temperatur...
Assessment of management policies for lake Ulubat basin using avswat
Bulut, Elif; Aksoy, Ayşegül; Department of Environmental Engineering (2005)
This thesis assesses phosphorus loads and management practices to control nutrient transport to Lake Uluabat. It analyzes nonpoint sources of pollution, especially agricultural pollution, throughout Uluabat Basin (watershed). AVSWAT (ArcviewTM Interface of Soil and Water Assessment Tool 2000) was used in determination of phosphorus and sediment loads to Lake Uluabat. Contribution of soluble phosphorus (SOLP) loads from agricultural sites was discussed. Seven scenarios were applied through watershed area to ...
Project appraisal and selection using the analytic network process
Dikmen Toker, İrem; Birgönül, Mustafa Talat (Canadian Science Publishing, 2007-07-01)
Where prioritization and selection process of large-scale construction projects is concerned, governments should consider various quantitative and qualitative criteria when choosing the best project alternative. The traditional benefit-cost (B/C) analysis has some drawbacks in terms of analyzing qualitative attributes that cannot be easily expressed in monetary terms. To eliminate this limitation, multicriteria decision-making techniques are proposed for the solution of project prioritization problems. In t...

Integrated solid waste management (ISWM) is used in order to sustain social and environmental quality within a city by using various treatment methods in parallel. On the other hand, in developing countries, solid waste management is one of the biggest challenges in the large cities. The increase in the population, thus the waste generation arises budget deficits for municipalities due to high management costs. The current waste disposal and management method applied in North Cyprus causes pollution to the ...
