Although some materials such as wood, glass and metals, which
are components of MSW, are building materials, it is unclear if
these materials wastes were generated from construction activity
as they could also originate from activities unrelated to construction.
It is interesting to note that although detailed studies of
MSW exists in Thailand (Pollution Control Department of Thailand,
2006; World Bank Group, 1999), there is a dearth of information on
the management and recycling of construction waste as no system
to record the amount of collected construction waste exists. Thus,
there is an obvious need for a waste management system which
tracks wastes from their origin as well as details their composition
and other relevant parameters (e.g., volume).
