The conditions, issues and problems of urban waste management in the industrialized and developing worlds are different. Though the developed countries generate larger amounts of wastes, they have developed adequate facilities, competent government institutions and bureaucracies to manage their wastes. Developing countries are still in the transition towards better waste management but they currently have insufficient collection and improper disposal of wastes. Clear government policies and competent bureaucracies for management of solid wastes are needed urgently especially in countries where there is rapid population growth through urbanization into peri-urban areas. Services and programmes that include proper waste disposal for management of hazardous biological and chemical wastes, minimisation and recycling will be needed. Disposal of wastes is commonly done by dumping (on land or into water bodies), incineration or long term storage in a secured facility. All these methods have varying degrees of negative environmental impacts with adverse environmental and health risks if wastes are improperly disposed or stored.
