The disposal rate of HW in China in 2002 was only
13.5%, which reflects the low technical level of disposal
facilities in China. Currently, high-level disposal facilities
are not adequate to satisfy the disposal requirements.A lot
of HW was disposed of by being mixed with ISW, or even
with MSW. For example, coal ash, boiler slag, and MSW are
often mixed with waste chemicals, reagents, and paint.
