WORLD population continues to rise with projections
nearing 7.2 billion by 2015 [1]. “The increasing
volumes of waste being generated would not be a problem if
waste was viewed as a resource and managed properly” [2].
Municipal Solid Waste (MSW) is the most complex solid
waste stream, as opposed to more homogeneous waste streams
resulting from industrial or agricultural activities [3]. MSW is
defined to include refuse from community activities, such as
residential households, commercial and business
establishments, fresh markets, institutional facilities and
construction and demolition activities, and to exclude
hazardous and infectious wastes.
The increase of MSW generation rate and the diversity of
MSW types cause by the increases of population, changing
consumption patterns, economic developments, changing
incomes, and urbanization. Increased MSW generation creates
more environmental problems. Solid waste has been one of
the environmental problems in urban areas of Thailand. The
main effect is the environmental degradation, caused by
insufficient MSW disposal. The disposed MSW impact is
composed of: (i) the odor from landfills, (ii) the groundwater,
surface water and soil contamination from leachate,
