The challenges of the SWM sector are continuing to grow with the growing urbanisation. Urbanisation has become a worldwide trend, and is particularly rapid in the developing world. The urban population of the world is expected to double to more than five billion people in the next 35 years, with 90% of this growth taking place in developing countries (World Resources Institute, 1997). In tandem with the growing urban population, the production of solid waste is also increasing. A report by the World Bank estimates that solid wastes in urban areas of East Asia alone will increase from 760,000tonnes/day to 1.8 million tonnes/day within 25 years, while waste management costs will almost double from US$ 25 billion to US$ 47 billion by 2025 (Urban Age, 1999). It is clear that SWM in future will expand in scope and complexity. It will also consume a considerable proportion of city budgets. The SWM sector, therefore, deserves careful attention for striking a balance between quality of service and cost effectiveness. This challenge is particularly significant for developing countries, where resources are limited but urbanisation is occurring rapidly. This article discusses the possibilities and challenges of partnership between public sector and private sector for better SWM service delivery from theoretical as well as practical points of view.
