Development of DPSIRO framework indicators for municipal solid waste management: a case of Bahir Dar city, Ethiopia

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.
