Economic analysis of solid waste (SW) management options in Morogoro municipality
was conducted to assess efficiency of solid waste management options in Morogoro
Municipality. The study set out three specific objectives: to analyze the types and
sources of MSW produced in Morogoro municipality, to assess possible SW
management options in Morogoro municipality and to conduct Cost benefit analysis of
solid waste management options in Morogoro Municipality. Using structured
questionnaires, data were collected from households as waste producers, key informants
interviews and focus group discussion were used to gather information from waste
collectors and processors. Analysis was done by descriptive statistic, Microsoft excel
and Cost benefit analysis. The study revealed that a major type of SW generated is
organic/food waste constituting about 60.2%, their main sources being residential and
commercial. Available management options in the municipality are recycling,
composting, dumping and locally dug pits. The study applied CBA to determine an
option which is economically efficient, and the results suggested that both recycling and
composting are profitable since they had positive NPV’s but recycling outlined to be
most economically efficient since it had a higher positive NPV compared to composting.
Sensitivity analysis revealed that, for risk management, it is profitable to undertake both
management options at lower discount rates than higher discount rates. Based on the
findings, the study recommended that waste sorting at source and management options
should be extended to the household level. Likewise, government should encourage
investments in composting and recycling, since they are viable and efficient SWM
options.
