Life cycle costing for decision making in construction and demolition waste management: A critical review

Construction and demolition (C&D) waste poses many environmental issues. There are many issues due to C&D waste landfills and construction industry has to face many costs when managing C&D waste. Currently there are many research studies carried out focusing on the C&D waste management. Even the environmental impacts of C&D waste is significantly researched, there is a minimum focus on the economic impacts of C&D waste management. Therefore, this research study aims to review the research carried out in C&D waste management focusing on its life-cycle costs. VOSviewer was used to develop the bibliographic networks and analyse the literature. Researchers conducted searches separately and both in conjunction of these two research domains. Most of the C&D waste management research focused on recycling and recycled aggregates. There is a clear lack of research on costs and economic point of view on C&D waste management. Few studies on costs for C&D waste management merely presented cost comparisons for specific waste management plans. Research on economic evaluation and specifically on life-cycle costing perspective for in C&D waste management paradigm is highly desired. Recycling is highly regarded in C&D waste management research. However, the life- cycle perspective of the extended life of recycled material is rarely discussed. There is minimum research carried out on monetising social benefits of C&D waste management.
