“…The state change of the environment was quantified in terms of greenhouse gas emission, eutrophication potential and leachate using mathematical models. Using an intergovernmental panel on climate change (IPCC) model, the total amount of CO2 and CH4 emitted from Bahir Dar city waste was estimated (Misganaw & Teffera, 2021). According to IPCC guidelines, the equation for measuring methane emissions from waste disposal sites was calculated using equation1.…”

“…This indicates that 47,772 ton of compost can be made from 86 percent of biodegradable garbage per year. The average total amount of money produced per year, according to this product, is around 1,313,724 Birr (Misganaw & Teffera, 2021).…”

“…Three main driving forces: natural population growth rate, economic growth and rapid urbanization are led to generation of municipal solid waste in case of Bahir Dar city. With a waste generation rate of 0.223kg per capita per day, the municipal solid waste produced in Bahir Dar city increased from 73.05 tons per day in 2007 to 148.13 tons per day in 2020 (Misganaw & Teffera, 2021). The average annual population growth rate of 6.6 percent is one of the key factors that determines the shift in urban solid waste generation rate (Biruk, 2017;Tirusew et al, 2013).…”

“…The aim of the study was to apply the Driving force-Pressure-State-Impact-Response-Outcome (DPSIRO) framework to study the potential impact of municipal solid waste on air, soil and water quality and develop sustainable indicators to reduce the impact. The DPSIRO framework is an extension of the DPSIR framework and it is a cycle which relates to a particular human need and accompanying activities (Misganaw & Teffera, 2021). The DPSIRO framework analysis describes that economic and social development, which are common driving force (D), exert pressure (P) on the environment, and, as a result, the state (S) of the environment such as depletion of natural resources and degradation of environmental quality changes.…”

The generation of MSW in urban areas in Ethiopia and elsewhere continues to increase and poses a challenge to city governments and citizens if the wastes are not properly managed. Applying an integrated system for managing MSW and recovering the material for use in new products can reduce the negative impacts on the environment. The purpose of this study is to apply the DPSIRO framework to develop a system that reduces the negative impacts of MSW in Bahir Dar city in a sustainable way. The research started by identifying the main driving forces that lead to the generation of MSW. Then, states because of pressures and the consequent impacts were investigated. Finally, the appropriate responses and outcomes obtained from the responses were dealt with. Methods used to quantify GHG emissions, leachate, and eutrophication potential were applied. According to the findings, the waste disposal site emits an estimated 46Gg of greenhouse gases per year in 2020.The eutrophication capacity of organic waste generated in the city was 0.0594 Kg N-equivalent or 59.4g N-equivalent. The waste also contains an average of 1,112mm of leachate per day on an annual basis. The state of the environment has an impact on human health and the ecosystem. Applying the circular economic system, knowledge transfer, and waste management fees are the main responses suggested to decision and policy makers. The responses correspond with balanced economic, social and environmental situations. Outcomes were quantified in terms of organic fertilizer, income and renewable energy (briquette) when the actions were taken.
