Waste to wealth: Incinerated municipal solid waste ash / Salmaliza Salleh

In developing countries such as Malaysia, waste management is
becoming an acute problem as urbanisation and economic development
increased rapidly. Due to deficient of landfill spaces, incineration is
gaining increasing consideration from the government as an alternative
method of solid waste management. Although 95% reduction in solid
waste volume can be achieved by incineration, it produces large amount
of ashes. Using the concept of powder metallurgy, the ash is treated as
powder and its commercial potential is discussed.
