A newly developed and tested survey instrument assessed the impact of individual beliefs, norms, and attitudes on the adoption of circular practices in the building industry, with a focus on reuse behaviors in renovation and construction. The findings indicate that while attitudes indirectly influence organizational intentions, norms, and perceived behavioral control directly relate to reuse intentions. These results highlight the critical role of psychological factors in promoting sustainable practices within the industry, emphasizing the need for further exploration of how these elements interact to advance environmental responsibility.
