Environmental Aspects of Sanitary Landfill Site Selection and Design for Municipal Solid Waste of Kandahar City, Afghanistan
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 7
Abstract
Concerns about global, regional and local emission of pollutants are at the alarm level especially in term of MSW. Increasing standard of living along with rapid urbanization and the limited capacity of the existing MSWMS make Afghanistan’s major cities, for example, Kandahar City to tackle with the problem of MSW management and hence it is needed to make attempts to shift from primitive MSWMSs toward IWMSs. The first objective of this study was to find out the composition of MSW at disposal site and at houses and shops to know the composition at early disposal and at landfills and amount of recyclable materials during these two stages. It was shown that composition of MSW is affected mostly by construction materials and it has no yard waste and less food waste at disposal site but at the houses and shops the food waste almost made 70% of the composition that is because of Kandahar hot and dry climate and that MSW takes 3-7 days to be disposed at landfill from houses. Moreover, it doesn’t produce much leachate and is simply evaporated in the open space. The second objective which was to select a site for sanitary landfill was obtained by studying and analyzing several potential areas around Kandahar City. Among the areas many factors of the (area near to Kandahar Air Field) were comparable with the standards for a sanitary landfill and hence the research suggested this area first. The third objective of the study was to design a sanitary landfill based on the composition of MSW obtained in the first objective and site selected for the sanitary landfill. The design was done for a 20 year period for the population of Kandahar City. As the soil and water table of the selected site was preferable, the design had not any special case and therefore components of a simple and basic sanitary landfill were calculated for its design.
