ABSTRACT
Waste incineration has been widely adapted as an effective means
to sanitize and to reduce the volume of waste before landfilling
in several countries such as Japan, Switzerland, and Sweden. Air
pollution, including dioxin emission, and some issues on the waste
incineration had been already cleared by the effort of technology
improvement under the strict regulations in these countries.1
On the other hand, the recent movement for sustainable waste
management has also promoted the effective utilization of waste
incineration ash. The secondary usage of waste incineration ash
from municipal solid waste incineration (MSWI) plants has been
suggested as an “artificial ore”2 or for use as a construction material
by cementation or vitrification,3 but a large portion of the ash is still
disposed of in waste landfill sites.
