Sustainable financing for municipal solid waste management in Nepal.

ABSTRACT: Financing municipal solid waste (MSW) services is one of the key challenges faced by cities in developing countries. This study used plastic waste, a constituent of MSW, to explore the possibility of generating revenue for financing MSW management in the municipalities of Nepal. The results of this study suggest that plastic material recovery could generate revenue, which is equivalent to 1.38 times of the plastic-waste-related management cost when collection efficiency reaches 66.7%. An increase in 1% of recovery rate and collection efficiency could cover an additional 4.64% and 2.06% of the costs of managing plastic waste, respectively. In addition, an increase in tax on imported plastic materials could also motivate recovery of plastic waste for recycle and reuse. An additional 1% tax on plastic imports would be sufficient to cover plastic-related waste management when plastic waste recovery and collection efficiency rates are low. This plastic recovery- revenue exercise could be expanded to other materials such as paper and metal to fully understand the possibility of sustainable financing of MSW management and reducing environmental harm in developing countries like Nepal.

Project description:Municipal Solid Waste (MSW) management has been a long-standing problem for many cities in developing countries. Urbanization, population growth, and excessive demand for resources caused significant waste related environmental and socio-economic problems in cities. Integration of policy decisions with actionable targets and management of economic and environmental extremes were common challenges to achieving sustainable waste management strategy. Circular economy is a concept that has been evolved with sustainable resource management perspective adopted in this study to support scientific decision-making process for urban planners and policymakers. Life Cycle Assessment (LCA) is a framework to assess the environmental impacts of waste life cycle ranging from waste generation, transportation, treatment, and end disposal. This study used the LCA framework to evaluate the impact of MSW management of a selected local authority in Colombo, Sri Lanka, to identify the environmental impact of four (04) proposed scenarios in comparison with the Business-As-Usual (BAU) scenario. Environmental impacts were calculated using global warming potential in terms of greenhouse gas emissions and short-lived climate pollutants. The results revealed that management of MSW within the local authority boundary by integrating recycling, incineration, and sanitary landfill (3:8:1 ratio) offered the highest positive impacts (- 121.84 kg of CO2 eq./ton) while BAU scenario caused the highest negative impacts (250.97 kg of CO2 eq./ton) in comparison with selected scenarios. Moreover, incineration, sanitary landfill, recycling, and anaerobic digestion contributed to emission savings and energy generation. LCA framework was used to identify the composition of MSW for suitable technologies as well as to evaluate the efficiency of existing management mechanisms within a local authority. Evaluation was used to understand the holistic picture of multiple management options to support policymakers in the decision-making process. This framework can be used as a benchmarking tool and bridging concept between the waste management policy and local action plans, which is an important step towards achieving a circular economy for developing countries.Supplementary informationThe online version contains supplementary material available at 10.1007/s43615-022-00200-x.
