ESTIMATION OF MUNICIPAL SOLID WASTE AVAILABLE FOR POWER GENERATION IN COCA-COLA, ILESA, OSUN STATE

Abstract

Municipal solid waste generation is a day-by-day activity by individuals, groups of people, and
industries. The rate at which waste is generated varies due to some factors such as population growth
and urbanization to mention a few. In knowing the amount of waste available for power generation in
a day, waste collection and analysis were organized at the Coca-Cola community, Ilesa, Osun State,
for eight consecutive weeks, in which the characteristics of the waste gathered in terms of contents
were obtained by manual sorting through the use of hand picking with gloves, shovel, and garden
hand fork. 15% of the initial total waste collected was partially good and considered for reuse and
recycling. The remaining contents of the waste collected were sorted into twelve waste fractions, in
which only eight under biomass and non-biomass combustible wastes were capable of generating
energy by Biochemical and Thermochemical methods of waste conversion. It was recorded that
87.3% of the remaining waste streams after recycling, which is equivalent to 2.06 tons/day were
available for energy (electricity and heat) generation in this area. This total waste in a ratio of 3.5:1 of
biomass to non-biomass combustible wastes, was presumed to take care of 10% of power demanded
in the community.
