The generation, use and disposal of waste crankcase oil in developing countries: a case for Kampala district, Uganda.
Waste crankcase oil (WCO), the oil that is removed from motor engines during an oil change, is frequently discarded into the environment, resulting in pollution of both aquatic and terrestrial ecosystems. In some developing countries, this common hazardous material is not properly managed. In Uganda little is known about its generation, utilization, and disposal. These factors were investigated using in-depth interviews of a sample of mechanics from 379 motor repair garages and 109 fuel stations in the Kampala district. Most garages (94%) and fuel stations (96%) in the study area offered oil-changing services. On average, each garage produced 62 l, and each fuel station produced 134 l of WCO per week. In garages 35% was sold, 16% poured on the ground, 18% taken by vehicle owners and 31% given away for free. At fuel stations, 49% was picked by private collectors, 27% sold, 4% poured on the ground, 2% burnt, 13% taken by vehicle owners, and 6% given away for free. Uses of WCO included coating roofing timber and fencing posts, use in timber cutting, marking play grounds, and pest control in animals. Its disposal involved burning, and pouring in the environment. Lack of policy and information for proper handling of WCO contributed to the poor management of WCO exhibited.
