Abstract
Wolkite is a town like many developing countries, faces problems associated with poor solid waste management. The town has only one major landfill site, which is found at Gasore kebele, near to the town. However, the waste dumping in this site has been affecting the surrounding community. The objectives of this study were to evaluate the current solid waste deposal site and socioeconomic impact of the current solid waste disposal site in the study area. The data were collected through field observation, key informant interview, focus group discussion, and household survey. Geospatial data were also used to evaluate the current solid disposal site. In this study, fifty-two household and two focus group discussion were participated. The quantitative data coded and analyzed using SPSS software. The data described using descriptive statistics and qualitative data were also expressed using narrative description whereas the geospatial data were analyzed by ArcGIS. The study result showed that the landfill site is proximate to stream and river, church, mosque, rural settlement, main road, and vegetation. The disposal site has affecting negatively to the local community; besides, the municipal waste is disposed arbitrarily on open field, roadside, dumped everywhere and solid waste disposed jointly with liquid at the landfill site, therefore, this study recommends to select suitable landfill site in the of the town.
Highlights
The current challenges in developing countries is selecting the most suitable area for disposing municipal solid waste (Kharlamova et al 2016)
The house hold, key informant and Focus Group Discussion (FGD) stated that Gasore kebele has one official landfill site, which is 12 km far from the center of Wolkite town
The solid waste collected from Wolkite town is disposed at the final landfill site found at Gasore kebele without further characterization i.e. the solid wastes that have been collected from different source in the Wolkite town were disposed together
Summary
The current challenges in developing countries is selecting the most suitable area for disposing municipal solid waste (Kharlamova et al 2016). World cities generate about 1.3 billion tons of solid waste per year (Orhorhoro and Oghoghorie 2019). This volume is expected to increase to 2.2 billion tones by 2025 (Kharlamova et al 2016) and by 2050 to raise 3.40 billion tons annually (World Bank 2018). An integrated system for waste disposal site selection is need to reduces the growing challenge of municipal solid waste management (Asefi and Lim 2017). Integrated solid waste disposal is a final functional element in the solid waste management system because disposal activities are associated with final dump of solid wastes directly to a landfill site
