Identification and analysis of barriers for construction and demolition waste reduction on commercial construction sites

Objective: This study identifies and assesses the barriers to reducing construction and demolition waste (CDW) in medium-sized commercial construction sites in Brazil. Methodology: A systematic literature review was conducted to identify and classify the main barriers to CDW reduction. Subsequently, the Fuzzy Dematel technique was applied to analyze the barriers based on managers' knowledge. Originality: Synthesizing insights from existing research on CDW reduction challenges, the study classifies these barriers into technical, economic, and legal dimensions within the Brazilian civil construction sector. Through the analysis of these barriers from professionals' viewpoints, the research makes a distinctive contribution by providing a novel, focused examination within this specific context. Results: The research revealed key economic, environmental, and technical factors. Results highlight the influence of legislation and government incentives on other barriers. The lack of financial resources emerged as a significant barrier to CDW reduction, according to managers' opinions. Contributions: This study contributes to advancing the circular economy by identifying key barriers to reducing CDW in medium-sized commercial works. It provides practical recommendations to overcome these barriers, offering valuable insights for both theoretical development and practical applications.
