The results obtained indicated that Thailand’s construction
industry generated an average of 1.1 million tons of construction
waste per year (see Table 3). On the basis of Thailand’s population
from 2002–2005 (ASEAN, 2005), and using the construction activity
time-series data for the same period (National Statistics
Organization of Thailand, 2007), it was observed that the amount
of construction waste generated in Thailand has grown over time.
Approximately 12 kg of construction waste was generated per person
in 2002; this amount had risen to approximately 18 kg in 2003
and 22 kg in 2004, with a slight decrease to about 20 kg/cap in
2005 (Table 3). This implies an average rate of construction waste
generation of about 18 kg/cap/year for Thailand within this period.
The slight decrease in the amount of waste produced in 2005 could
