Abstract
Basic measures taken in recent years to control waste management in Japan include: (1) Pollution prevention, (2) reuse and recycling, and (3) waste incineration with air pollution control. It is generally agreed that it is appropriate to follow the assigned priority of these options. Municipal solid waste (MSW) is the responsibility of the citizen, the local government and the business sector. The principal strategy to manage MSW is to prevent the discharge of waste and, where waste must be discharged, to recycle as much as possible to reduce the quantity. However, even if effort is made to minimize the amount of waste, a large proportion still requires treatment in view of the activities of modern society. Once waste is generated, it must be incinerated and/or buried in landfills if it cannot be recycled. Incineration plays an important role in Japan where landfill sites are difficult to secure. With these circumstances in mind, the author outlines the origin of MSW in Japan and the recycling process and the present status of thermal recycling with pollution control. Ash regulation and its treatment methods are also discussed.
