solidwastekampala: Quantity and Composition of Domestic Solid Waste in Kampala City

Description

Household-level results of a seven-day domestic solid waste characterisation in three parishes of Kampala City, Uganda (Bwaise I = low income, Bukoto I = middle income, Ggaba = high income). For each of the 103 analyzed households the data record socio-economic characteristics, the measured mass of ten waste categories, and the derived per-household metrics (total, per-day, per-capita, volume, and density).
