Dar es Salaam in Tanzania has been regarded as a leading successful example of privatised solid waste management by UN Habitat, yet in fact, the privatised system failed to keep the city clean. Residents are not satisfied, as it is considered too expensive, unreliable and does not cover the entire area. The privatised waste management service is mainly financed through household payments.
Seeking to solve these problems, communities across the continent have developed waste management solutions specifically tailored to meet local and regional needs. In the Egyptian cities of Cairo, Alexandra, and Giza, local authorities, community members and workers have brought waste services back under public control and with it, ended years of inefficient waste management.
After years of protests, the Egyptian government eventually accepted that privatisation was a failure, and Cairo, Giza, and Alexandria had public waste collection systems reinstated. In 2011, the latter became the first city to end its private contract with Veolia and establish its own, state-owned enterprise, Nahdet Misr, to operate waste services. The Zabaleen in Egypt demonstrate that there is a huge potential for zero-waste programmes in Africa.
