| Abstract |
Recent policies on environmentally friendly construction waste management emphasize legal compliance over proactive waste reduction and
recycling. To address this issue, this study gathered insights from stakeholders involved in construction waste disposal, including contractors
and intermediate processors, using the Analytic Hierarchy Process (AHP) to identify and prioritize improvement strategies. A combination of
literature review and expert interviews led to the identification of 15 evaluation criteria grouped into three key factors: environmental,
economic, and technological. Among these, economic factors emerged as the most significant, with reducing waste disposal costs at
construction sites ranked as the top priority. Alternatives such as waste reduction, reuse, recycling, landfill, and incineration were assessed,
with recycling identified as the most critical strategy. The findings emphasize the need to balance stakeholders' economic interests with
long-term investments in environmentally friendly technologies. Practical recommendations include optimizing disposal processes, incentivizing
recycling efforts, and developing supportive policies to bridge the gap between legal compliance and effective environmental action.
Advancing technologies for waste sorting and processing is also essential for improving management efficiency. This study provides a
comprehensive framework for sustainable construction waste management policies and practical applications. The results aim to reduce
economic burdens, enhance environmental responsibility, and build social trust within the construction industry. By aligning economic
incentives with environmental objectives, the research contributes to establishing a sustainable resource cycle and addressing the critical need
for better construction waste management practices. |
