Rwanda is a fastest developing country where the urbanization is extensive and accelerates the increase of waste generated from households. Biodegradable organic matter constitutes a great portion of Municipal solid waste from Kigali City. The research was focused on the composition and quantification of Solid Waste destined in Kigali City dumpsite. The survey was carried out in Nyarugenge Sector of Nyarugenge District, city of Kigali with three selected cells and in each cell, two villages were selected in each village. The survey was conducted every week for four weeks corresponding to a month, to estimate the quantity of municipal waste discharge over a day and 60 households sample were involved in the research. Moreover, this survey was conducted between 24/June and 21/July. The sorting-and-weighing methodology was used for assessing the waste composition from each of the sample households for each week. The sorting-and-weighing methodology was used in assessing the waste composition from each of the sample households for each week. In the survey, the amount of solid waste generated and disposed of in each of survey areas (villages) as quantified, was found to be 686.000 kg. The result showed variation of weight percentage of waste: plastics (4%), paper (3%), cartons (3%), glasses (2%), metal (1%), biodegradable organic wastes (75%), others (clothes, shoes, bones, hair, pampers) (14%).
