Life cycle cost (LCC) for waste to compost process: Evaluation of life cycle cost for the comparison of decentralized waste to compost and landfill facility in Dhaka North City Corporation (DNCC)

Abstract

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.
