    • 12 Executive summary To achieve the objective of integrated resource and waste management, new ways of policy-making will be needed that include a structured dialogue between numerous stakeholders. Waste management institutions will be challenged to contribute to that dialogue, the topics of which will include the whole picture and range from the supply of primary resources, production and trade, to transport and consumption. As a result of this comprehensive approach, the goals of waste minimisation and decoupling of economic growth and waste generation may finally be achieved.

Since the development of legislation and establishment of long-term treatment and disposal facilities will take ten to 15 years, it is important to develop interim or transitional facilities in the short-term to allow the rapid phasing out of uncontrolled dumping. Industrialising countries cannot wait until they have detailed waste data and an infrastructure in place before taking action. It is better for them to do something now than to investigate for too long.Transitional technologies offer that short-term solution. There are three main objectives, which need to be addressed if environmentally developing countries are to improve their control and management systems for hazardous wastes.
