A comparison of municipal solid waste management in selected local authorities in Sri Lanka

Abstract

Solid waste has become a critical issue with rising population, urbanization, economic activities and consumerism, especially in urban centers creating a negative impact on environment due to inappropriate handling of municipal solid waste. Further, social, economical and health issues such as unpleasant odor, ground water contamination, epidemics and social effects also are being created due to land filling. Lack of physical, human and financial resources, poor participation and less enthusiasm among community groups and government representatives overloaded with additional work none related to solid waste activities are significant challenges. Equally, literature revealed that existing SWM systems established within most local authorities are not properly operated and maintained in Sri Lanka. Hence, significant gaps are visible in solid waste management activities at local authorities. Thus, this research intends to explore municipal solid waste management systems in Sri Lanka to identify best practices. Case study research approach was used and multiple cases were selected representing both best and worst practices in municipal solid waste management. Data were gathered through semi structured interviews. An outcome of the study is a framework developed for best practices of solid waste management which can be used at local authorities for effective and efficient municipal solid waste management.
