Abstract
Less than 10% of the population have access to electrical and thermal energy in Uganda and there is a
heavy dependence on wood fuel as a source of energy. In this study, the energy potential of Municipal
Solid Waste at Kiteezi landfill, Kampala was qualitatively determined by carrying out Municipal solid
waste (MSW) characterization, proximate analysis, and calorific value measurements. The samples
were picked on different days and for each day, waste was randomly selected from five garbage trucks
coming from residential areas (private trucks) and commercial areas (Kampala City Council Authority
trucks). It was then sorted, weighed and packed in polythene bags and take to the laboratoty for
analysis. Waste from the commercial areas consisted of 87.3 % food and yard waste, 2.0% papers, 0.4%
plastics, 3.6% polyethylene, 2.2% water bottles, 0.9% textiles, 1.9% Glass, 0.2% metals, and 1.6% others.
Whereas the waste from residential areas comprised of 94.4% food and yard waste, 1.2% papers, 0.3%
plastics, 2.3% polyethylene, 0.6% water bottles, 0.4% textiles, 0.3% Glass, 0.1% metals, and 0.4% others.
The organic waste on average had moisture content (8.69 wt. %), volatile matter (73.3 wt. %), fixed carbon
(3.22 wt. %), and ash content (13.65 wt. %) on a dry basis. The organic waste also had a gross energy content
of 19.26 MJ/Kg of dry matter. It was concluded that the organic waste generated in Kampala city can
contribute positively to the energy sector.
