Abstract

The generation of solid waste has become an increasing environmental problem, especially in developing countries like Sierra Leone. The management of solid waste in Freetown is characterized by lack of waste treatment systems, low public participation, and weak legislation. This research aimed to analyze the waste management issues by employing Material Balance Analysis to determine the quantity of wastes that can be recovered at source through the application of 3R. An online google-docs questionnaire was used to collect waste management information from respondents from households in Freetown. Regarding waste reduction activities in Surabaya, a questionnaire was administered to members of Jambangan and Lebak Rejo waste banks that have implemented waste reduction activities. The survey data was analyzed using Statistical Package for Social Sciences (SPSS), Microsoft Office Excel, and Google Docs. In addition, this research employed SWOT Analysis to develop solid waste management strategies in Freetown, and Sierra Leone as whole. The research results showed that 29% of waste generated in Freetown is organic, inorganic materials 65%, while other wastes 6%. For waste reduction, the Freetown municipality has the potential to reduce 296 tons/day or 26% of recyclable waste, and 255 tons/day or 23.2% of compostable waste generated can be reduced. The research indicated that if 3R activities are implemented, 551 tons/day or 50.15% of the total waste generated can be reduced. Additionally, 55% and 36% of respondents stated that the regulation and policies on waste management are weak and have been poorly implemented. The SWOT Matrix results x=-2.11 and y= -0.76 indicate that MASADA Waste Management Company is weak and faces challenges in developing waste management systems. For community participation, the survey results showed that 96% of residents do not pay for collection service, while 4% of respondents pay waste collection. The main reasons for low participation are public awareness and education on waste management. Therefore, this research suggests the formulation of comprehensive regulations on 3R, incorporate community participation on waste management, and ensure the implementation of waste reduction activities at source and waste treatment facilities.
