Critical factors to influence the illegal dumping behavior of construction and demolition waste: An ISM-DEMATEL analysis

Illegal dumping behavior widely exists in the construction industry and is difficult to manage. What factors and how they influence the illegal dumping behavior of construction and demolition waste remains to be clarified. Specifically, this study employs an ISM-DEMATEL approach to investigate the critical factors that influence the illegal dumping behavior. It is found that the factors, ‘capital investment of enterprises’ and “stakeholders' willingness and attitude”, are vital to tackle the illegal dumping behavior of construction and demolition waste. Yet, compared with business-level factors, the macro-level factors such as ‘social norms and culture’ and ‘government incentive policies’ tend to be less influential. Moreover, enhancing the industry-wise administration system and practitioners' dedication to the issue can be an option to avoid illegal construction waste dumping. The results of this study serve to elucidate the influential factors and offer practical implications for addressing the issue of illegal dumping of construction and demolition waste.
