Abstract-This study investigates the adoption and impact of circular economy practices in Thailand’s construction industry, focusing on perceived benefits, sources of construction and demolition waste, and the outcomes of various circular economy strategies. A survey of 400 industry professionals revealed that cost savings from material reuse (36%) and enhanced corporate image (22%) were the top perceived benefits. The demolition of old buildings (35%) was identified as the primary source of construction waste. Among the circular economy strategies, the use of recycled aggregates led to a 28% reduction in raw material costs, while on-site waste sorting and recycling resulted in a 20% increase in material reuse. Although less frequently implemented, modular construction and closed-loop water recycling also contributed positively. The findings underscore the need to expand and strengthen circular economy practices to promote sustainable development within Thailand’s construction industry.
