| Popis: | With the rise of urbanization, change in lifestyles, and food habits, the amount of Municipal Solid Waste (MSW) has been rapidly increasing with the composition constantly changing. Landfilling is the common approach for waste management in Kuwait, and around 90% of municipal wastes are disposed in landfill sites. Therefore, this study focused on the integration of different methods for the process of allocating optimum sites for MSW landfills, in four main stages. The first stage focused on utilizing the gap analysis method for the identification of effective criteria for landfill site selection, by comparing the criteria in Kuwait with the World Bank guidelines, US EPA, and Australia EPA, to suggest the best criteria for landfill site selection. These criteria were applied in the second and third stages to determine suitable locations for landfill sites using the Geographical Information System (GIS). In the last stage, the suitable areas were evaluated by studying the socioeconomic aspects such as distance to waste generation center, the proximity of existing roads, and lifespan to select optimum locations for landfilling. The results indicated that only one site with a total area of 12 km2 was considered optimum for MSW landfill sites in Kuwait. Therefore, moderate suitability areas were indicated to support and provide decision makers with more options. The moderately suitable sites are also suitable for landfilling, but they need to be designed carefully in order to avoid negative impacts on the environment and human health. Therefore, we conclude that there is an urgent need to apply the integrated waste management system in Kuwait, as well as to develop a long-term strategic plan. |
