Introduction
Per capita generation of municipal solid waste (MSW1
hereafter) in the developed countries has increased
threefold over the last two decades. It is predicted that waste generation in the developing countries will be doubling in
the coming decade and global waste will be increased fivefold by 2025 (Brandsma, Dec. 1997: 6-7). Indeed, how to
resolve waste problem has become of enormous pressure for government policymakers. Even until a decade ago,
however, major concern about waste problem had been such issues as reduction of waste generation itself and new
facility siting.
