Abstract
World Bank research on appropriate technology for water supply and waste disposal has revealed a need for further research and development in integrated systems for recovery and utilization of household and community wastes. Technology options including resource recovery are reviewed with special emphasis on constraints arising particularly in developing countries. Cost control and recovery is complex, and it has rarely if ever been demonstrated that a potential exists for making a solid waste management project profitable in its entirity. Solid waste management represents a net cost which may be minimized by better operations and appropriate recycling. Financial and economic backgrounds including tax structures have an overriding influence on apparent costs, and sound financial management is essential. Hazards of relying on the commercial sector alone to manage waste collection and disposal are emphasized as well as the long term problems with highly sophisticated equipment in countries that lack Foreign exchange and local skills for their maintenance and repair.
