In El Salvador, qualified solid waste management, which involves control of generation, collection, transportation, recovery/reuse, treatment processing, and disposal of wastes is eager to be developed. The final disposal in this country has gradually improved in recent years by switching from open-air dumping to the constructions of landfills, even though it still is not constructed in a manner according to the best principles of public health. For reducing the loading of landfill that can sustain the life-time of the operating landfills in El Salvador, this study focuses on finding a viable and feasible alternative for the recovery and utilization of solid wastes applied in San Salvador, the metropolis of El Salvador. To collect the public’s opinions of establishing a recovery plant in San Salvador for assessing the social situation, a questionnaire survey was carried out. Furthermore, a brief financial analysis was also prepared to evaluate the economic feasibility of establishing the plant.
The population of San Salvador in 2012 will be 2,021,171 people, and with 1.61% annual increase rate, in 2026 the population will increase to 2,527,629 people, and MSW amount will be 894,907 tons per year that is 2,452 tons per day. For having a MRF plant to effectively recover the resources of MSW in San Salvador, the design capacity of the recovery plant is 1200 ton per day constructed on the land area of 3.3 hectares. The municipal solid waste plant is designed to majorly separate paper and cardboard, aluminum, glasses, plastics, and other valuable materials. The material recovery facility (MRF) includes size reduction units, screen separator, manual sorting system and packing unit. The MRF will be operating during its life-time of 15 years.
Base on the construction unit price (US$19,366 /tpd) of MRF plant in Viña del Mar, Republic of Chile, the proposed MRF in this study is estimated a unit price at US$21,300 per tpd (tons per day in design capacity). The initial construction capital for MRF of 1,200 tpd is US$25,560,000.The construction cost has included the costs of wastewater treatment system and air-pollutant filter. The major revenue is the sale of recovered materials produced from the MRF. According the market price of these recovered materials in San Salvador, and in the condition of that construction cost is come from government’s budget without interest payment, the results of financial analysis are that the IRR (internal rate of return) is 57%, and payoff period is two years. A sensitivity analysis is used to assess the impact of the actual outcome of a particular variable. In sensitivity analysis, we assume the sale prices of recovered materials are lower 20% in the present market. In addition, we assume the operation cost is increased to 2% of the construction capital. The result shows that the IRR will decrease to 37%, and the payoff still needs two years.
