Enhancing construction and demolition waste management using swot and quantification systems

Abstract

Construction waste management and inventory are lacking in the Jordanian construction sector. With the dramatic population growth, the construction sector plays a significant role in developing the Jordanian economy. This article aims to develop a model to quantify construction and demolition (C&D) waste based on either project hyper-categorization or waste type, and to measure the degree of awareness and readiness of local contractors to benefit from C&D waste. Therefore, it classified projects further into construction and infrastructure projects. The construction project is also classified as new construction, renovation, or rehabilitation. These classifications help improve the management of construction waste. Moreover, a survey was conducted among construction stakeholders to increase awareness and assess their perceptions and readiness to adopt C&D waste management activities in their current or future projects. Finally, a strengths, weaknesses, opportunities, and threats (SWOT) analysis was conducted to heighten major stakeholders' awareness about the challenges of C&D and to develop an effective C&D waste management plan. The results of this research can help both decisionmakers and stakeholders in the construction sector properly classify their waste, reduce and manage generated C&D waste, and lower overall costs. Finally, the SWOT analysis identifies hidden opportunities to promote and develop a future C&D waste management at all levels. Meanwhile, revenue from recycling C&D waste is expected to be about US$4.2/m2 of construction.
