This study aims to assess the status of solid waste management (SWM) practice and to characterize and quantify the municipal solid waste as a measure toward effective management in Dilla town Southern Ethiopia. Formal surveys of household residents and SWM operators using a structured questionnaire were conducted to gather data on the current waste management practices of the inhabitants. Repeated field investigations, on-site waste segregation, characterizations, and quantification were conducted. The average per-capita waste generation rate of residential households was found to be 0.475 kg/capita.day. The majority of the waste was organic (68.40% by weight). The recyclable waste accounts 1.90% plastics and 1.50% paper by weight. Whereas, other wastes account 0.30% metals, 0.30% glass, 0.50% leather and rubber, 19.60% inert, 0.96% textiles, and 6.90% miscellaneous by weight. The awareness of inhabitants on solid waste management, poor household waste segregation practice, and disposing of an unsanitary landfill are revealing the main solid waste management problems faced. Other SWM barriers include ineffective solid waste fee system, lack of trained manpower, inappropriate collection routes; unavailability of collection vehicles, illegal solid waste disposal, and inappropriate setting of community containers. From the results of this study, it can be concluded that organic waste constituted a lion share of the solid wastes generated in the town. Hence, the municipality can recover this waste by introducing integrated urban agriculture that might convert this waste to organic fertilizer through composting. To boost SWM, creating public awareness, providing equipment, provision of incentives and other financial policies, and other supplies currently lacking and inappropriate must be provided. The municipal authorities of the town may use this work as a benchmark and might push environmental protection authorities to reexamine the implementation of their policies and strategies with relation to the human and environmental health of the town.: Nowadays, urban population is increasing in developing countries; led to generate an enormous amount of municipal waste in the areas which make more complicate its management pose environmental pollution and threat public health. Thus, to curve these problems this study finding will be important for various policymakers and town municipality. This study may also serve as a benchmark for the municipal authorities of Dilla town for whom the problem is still unseen and negligible, and can push environmental protection authorities to re-examine the implementation of their policies and strategies with regard to the wider issues of human and environmental health conditions of town inhabitants.
本研究旨在评估埃塞俄比亚南部迪拉镇的固体废物管理(SWM)实践状况,对城市固体废物进行特征分析和量化,以采取有效管理措施。通过使用结构化问卷对居民和SWM运营商进行正式调查,收集有关居民当前废物管理实践的数据。进行了多次实地调查、现场垃圾分类、特征分析和量化。发现居民家庭的人均垃圾产生率为0.475千克/人·天。大部分垃圾为有机垃圾(重量占68.40%)。可回收垃圾中塑料占重量的1.90%,纸张占1.50%。而其他垃圾中金属占重量的0.30%,玻璃占0.30%,皮革和橡胶占0.50%,惰性物质占19.60%,纺织品占0.96%,杂物占6.90%。居民对固体废物管理的认识、不良的家庭垃圾分类实践以及在不卫生的垃圾填埋场处置垃圾,揭示了面临的主要固体废物管理问题。其他SWM障碍包括固体废物收费系统无效、缺乏训练有素的人力、收集路线不当、收集车辆不足、非法固体废物处置以及社区容器设置不当。从本研究结果可以得出结论,有机垃圾在该镇产生的固体废物中占很大比例。因此,市政当局可以通过引入城市综合农业来回收这些垃圾,城市综合农业可能通过堆肥将这些垃圾转化为有机肥料。为了促进SWM,必须提高公众意识、提供设备、提供激励措施和其他财政政策,以及提供目前缺乏和不合适的其他物资。该镇的市政当局可以将这项工作作为一个基准,并可能推动环境保护当局重新审视其与该镇人类和环境健康相关的政策和战略的实施情况。如今,发展中国家的城市人口在增加;导致在这些地区产生大量城市垃圾,这使得其管理更加复杂,造成环境污染并威胁公众健康。因此,为了解决这些问题,本研究结果对各政策制定者和镇政府来说将很重要。本研究也可能作为迪拉镇市政当局的一个基准,对他们来说这个问题仍然未被重视且微不足道,并且可以推动环境保护当局重新审视其关于该镇居民更广泛的人类和环境健康状况问题的政策和战略的实施情况。
