The generation of municipal solid waste (MSW) in urban areas is rising globally and is having a negative impact on social, economic, and environmental situations. As a result, the environmental implications and resource recovery potential of MSW management systems are gaining traction. The major goal of this research is to evaluate Bahir Dar's solid waste management procedures by developing the Driver, Pressure, State, Impact, Response and Outcome (DPSIRO) framework indicators. Edraw Max and Cmap tools software were used to create DPSIRO framework indicators. Population increase, fast urbanization, and economic growth are all thought to be driving influences. The environmental state resulting from pressure was computed using the IPCC model and statistical analysis was done using SPSS software. The response indicators and respected outcomes are taken into account when the framework is conceptualized. In the years between 2007 and 2020, the population grew from 221,991 to 414,763. Driving force generates 73 tons of solid trash per day in 2007 and 148 tons per day in 2020. In 2020, the city's greenhouse gas emissions totaled 46 Gg/year. When the replies are implemented, the city may create around 47,772 tons of organic fertilizer, saving approximately 1,313,724 Ethiopian birr per year. According to the findings, Bahir Dar should begin implementing 3R solid waste management strategies to minimize potential environmental and human health risks while also maximizing economic benefits.

DPSIRO 城市固体废物管理框架指标的制定:以埃塞俄比亚巴赫达尔市为例

城市地区城市固体废物 (MSW) 的产生在全球范围内不断增加,并对社会、经济和环境状况产生负面影响。因此,MSW 管理系统的环境影响和资源回收潜力越来越受到关注。本研究的主要目标是通过制定驱动因素、压力、状态、影响、响应和结果 (DPSIRO) 框架指标来评估 Bahir Dar 的固体废物管理程序。使用亿图 Max 和 Cmap 工具软件创建 DPSIRO 框架指标。人口增长、快速城市化和经济增长都被认为是驱动因素。使用IPCC模型计算压力导致的环境状态,使用SPSS软件进行统计分析。在构想框架时,会考虑响应指标和受尊重的结果。2007 年至 2020 年间,人口从 221,991 人增加到 414,763 人。驱动力2007年每天产生73吨固体垃圾,2020年每天产生148吨。2020年全市温室气体排放总量为46Gg/年。答复实施后,全市可生产约47,772吨有机肥,每年可节约约1,313,724埃塞俄比亚比尔。根据调查结果,Bahir Dar 应开始实施 3R 固体废物管理策略,以最大限度地减少潜在的环境和人类健康风险,同时最大限度地提高经济效益。驱动力2007年每天产生73吨固体垃圾,2020年每天产生148吨。2020年全市温室气体排放总量为46Gg/年。答复实施后,全市可生产约47,772吨有机肥,每年可节约约1,313,724埃塞俄比亚比尔。根据调查结果,Bahir Dar 应开始实施 3R 固体废物管理策略,以最大限度地减少潜在的环境和人类健康风险,同时最大限度地提高经济效益。驱动力2007年每天产生73吨固体垃圾,2020年每天产生148吨。2020年全市温室气体排放总量为46Gg/年。答复实施后,全市可生产约47,772吨有机肥,每年可节约约1,313,724埃塞俄比亚比尔。根据调查结果,Bahir Dar 应开始实施 3R 固体废物管理策略,以最大限度地减少潜在的环境和人类健康风险,同时最大限度地提高经济效益。
