Evaluating Drivers and Barriers of Integrated Waste Management System Implementation in Indonesian Construction Industry: A DEMATEL-Based Analytical Network Process

The growth of construction industries in Indonesia creates an increasing level of generated construction waste. The limited implementation of ISO 14001 in the Indonesian construction industry might indicate the limited implementation of waste management based on sustainability principles. Therefore, this study aims to explore the drivers and barriers to implementing integrated waste management in construction industries. The Content Validity Index (CVI) and Modified Kappa methods were utilized to validate the indicators from the literature review. A total of 18 driver factors and 21 barrier factors in six dimensions were assessed by seven experts. This study then employs the decision-making evaluation and laboratory-based analytical network process (DEMATEL-based ANP) to find the weight and relation between each indicator and dimension. The results show that environmental awareness is the most important factor that drives construction industries to implement waste management in their company. In contrast, a lack of education about waste management is the most significant factor that inhibits construction industries from implementing sound waste management systems.
