Solid Waste Management
The collection, transportation and disposal of garbage in Kampala is the responsibility of Kampala City Council Authority (KCCA) according to the Solid Waste Management (SWM) Ordinance 2000. The city generates about 1,200–1,500 tonnes of garbage on a daily basis and KCCA collects about 400-500 tonnes of garbage on a daily basis leaving about 60% of the garbage uncollected. The uncollected garbage to some extent results into indiscriminate disposal of garbage by the public as they have nowhere to put it.
In Kampala city alone domestic waste generation is estimated to range between 0.5kg and 1.1kg per capita per day. The population of Kampala City and its suburbs is estimated at 1.7 million. The estimate of waste per capita generation per day is 0.5kg on the lower end. This translates into 850 tons of waste generated per day. Domestic waste generation is estimated to be on the higher level among high income residents of the city.
The most un-collected garbage is found where low income earners in the city live. The challenge is some of the residential areas occupied by low income earners are not properly planned in terms of access roads and water and sewerage systems. Therefore, the garbage and sewerage trucks cannot reach these places.
The dumping site of waste is located at Kitezi, Mpererwe Nangabo sub county Wakiso District. The estimated composition of waste is as follow:
Plastics under which polythene falls
tree cuttings, glass, metals, and paper
Energy Generation and Production of Manure from Waste
Municipal waste in Uganda is generally composed of wet carbon and nitrogen rich
materials that include: organic waste from households, agro industrial waste slaughter houses, food industry and agro waste: manure and straw. Over 70% of the municipal solid waste is vegetable matter which can be utilized for energy production.
The residents of Kampala City produce more than 500 tons of garbage on a daily basis of which more than 73% is vegetative matter.
The waste can be used to produce biogas which can be used for domestic fuel and for power generation.
The combustible waste matter and the biogas can be used for electricity generation.
Production of manure
The end product from biogas generation is rich in nitrogen, phosphorous, potassium and humus and can be used to replace imported fertilizers and increase agricultural productivity on farms.
