Rate and Quantities of Household Solid Waste Generated in Kampala City, Uganda

Abstract

The study concentrated on solid waste (SW) generation at households to establish rate of generation, quantities and overall composition. Kampala divisions were purposively stratified according to existing parishes. Areas of data collection were further stratified into three income-groups of low, middle and high using the quality of housing. Descriptive statistics of Statistical Package for Social Scientists (SPSS) was then used to analyze the data. Findings revealed that 846,155 kg/day of household SW was being generated in Kampala at the rate of 0.56 kg/person/day. However, rates of SW generation for the three income groups were respectively 0.29, 0.75 and 1.34 kg/person/day. Post-hoc tests of multiple comparisons revealed significant differences in the mean values of household SW generated between divisions. The average composition of household SW were 83.6% vegetable / organic matter; 10.9% waste paper; 1.2% waste plastics; 0.3% waste metals ; 0.1% glass / cullet materials and 3.9% other materials
