“…Forty to sixty percent of Dhaka, Bangladesh's most signi cant city's daily 6,000 metric tonnes of MSW, predominantly organic kitchen trash, is disposed of incorrectly due to waste management issues (Ahsan, Alamgir et al 2014, Yasmin andRahman 2017). Inadequate results and considerable greenhouse gas emissions result from Dhaka's current garbage management systems ( (Sadab, Noor et al 2023). This research investigates the potential of waste-to-compost as a long-term solution to Dhaka's municipal solid waste issue.…”

Background Rapid urbanization and economic development in developing countries, such as Dhaka and Bangladesh, have led to an increase in municipal refuse. Traditional waste management practises, such as landfilling and conventional composting, have been shown to be ineffective and expensive owing to the large amounts of land required. Objective The purpose of this research is to do a Life Cycle Cost Analysis (LCC) of a Dhaka-based waste-to-composting operation. The objective is to examine how much money it would save in comparison to current practices so that urban waste management problems may be solved in the long run. Methodology: In order to evaluate the potential of the planned decentralized compost plant, LCC methods are used in the study. This includes an analysis of both upfront and ongoing expenses, as well as a comparison to more traditional approaches. Result The research found that the overall cost of the decentralized compost facility was $5,226,616, much less than the expenditures associated with landfilling and conventional composting methods in Dhaka. Conclusion This study shows that a decentralized waste-to-compost plant may be a profitable option for dealing with city trash. Its potential to ease stress on municipal governments is highlighted by its much lower price tag. Insightful for policymakers and urban planners in emerging nations confronting comparable waste management difficulties, this research stresses the need to implement such creative, cost-effective approaches in quickly rising metropolitan centres.
