Sustainability of private sector in solid waste collection: a case of Dar es Salaam, Tanzania
This research examines the sustainability of private sector participation in urban service delivery in developing countries. The solid waste collection service in Dar es Salaam – Tanzania was used as a case study. Municipalities in Tanzania have not been able to cope with the rapid generation rate of solid waste coupled by the rapid urbanization. This resulted in a relatively large quantity of solid waste remaining poorly managed and uncollected, which left an obvious gap for other stakeholders to participate in service provision. The private sector took the opportunity, in the early 1960s, to fill the gap left by the public sector in service provision.
The research found that there are factors affecting the sustainability of the private sector, which include: support from the public sector; capacity from the private sector in terms of collection vehicles and equipment; households’ attitudes and behaviour regarding the privatization of the service; the awareness and participation of households in the service; and involvement of households in decision-making. The research also identified that there is a missing-link between the households, public sector administration and the private sector. The research concludes that, taking into consideration the above factors, the proposed guidelines formulated in this study illustrate ways in which private sector involvement in solid waste collection in urban developing countries will be sustainable.
