“…These approaches are listed in ascending order according to their adverse impact to the environment from low to high. Among these methods, reuse and recycle is regarded as the best alternative for managing the generated waste because of its minimal influence on the environment in while reducing the cost of waste disposal (Tam, 2009). When reuse and recycle becomes difficult, waste should be disposed at landfills and/or public fills to avoid polluting the environment (Seadon, 2010).…”

Prefabrication has been widely regarded as a sustainable construction method in terms of its impact on environmental protection. One important aspect of this perspective is the influence of prefabrication on construction waste reduction and the subsequent waste handling activities, including waste sorting, reuse, recycle, and disposal. Nevertheless, it would appear that existing research with regard to this topic has failed to take into account its innate dynamic character of the process of construction waste minimization; integrating all essential waste handling activities has never been achieved thus far. This paper proposes a dynamic model for quantitatively evaluating the possible impacts arising from the application of prefabrication technology on construction waste reduction and the subsequent waste handling activities. The resulting model was validated based on an actual building project in Shenzhen, China.The simulation results of the design scenarios indicate that the policy on providing subsidy for each square meter of the prefabrication adopted in the construction would have more significant effect on promoting the use of prefabrication and improving the performance of construction waste reduction compared to the increase of income tax benefits. The results also show that (1) interaction exists among different management measures, and (2) the combined effect of multiple policies is larger than the simple sum of their individual impacts, indicating the need for comprehensive consideration on the combined effect of these potential polices. This paper demonstrates the potential benefits of using a system dynamics approach in understanding the behavior of real-world processes. The developed model not only serves as a practical tool for assessing the impact of off-site prefabrication on construction waste reduction and the corresponding waste handling activities, but also help provide a valuable reference to policy makers through the comparison of simulation results generated under various scenarios such that the best policy mix can be identified prior to production.

“…The main reasons for the increase of the volume of C&D waste are old structures that have overcome their use expectancy and need to be demolished, new requirements and necessities leading to the demolition of otherwise still viable structures and destructive natural phenomena like earthquakes and storms [4].…”

“…Recycled aggregates are produced by natural aggregates producers (50%), contractors (36%) and debris recycling centers (14%) [7]. In Japan, the concrete recycling ratio reached 98% in 2003, from 65% in 1995, the most common application being as sub-base material in road construction [4]. Tam [4] analyzed the situation of C&D waste recycling in Australia.…”

“…For some materials, such as steel or aluminium, recycling can confer savings of more than half the embodied energy as well as GHG emissions (Yan et al, 2010). Tam (2009) has commented that recycling concrete waste should be one of the best methods to improve its environmental impact but, in studies of the Australian and Japanese construction industries, major difficulties were found to be involved. In the UK, the majority of recycled and secondary aggregates have been used as alternatives to primary aggregates in local fill and related aggregates markets.…”

The construction industry is known to be a major contributor to environmental pressures due to its high energy consumption and carbon dioxide generation. The growing amount of carbon dioxide emissions over buildings' life cycles has prompted academics and professionals to initiate various studies relating to this problem. Researchers have been exploring carbon dioxide reduction methods for each phase of the building life cycle – from planning and design, materials production, materials distribution and construction process, maintenance and renovation, deconstruction and disposal, to the material reuse and recycle phase. This paper aims to present the state of the art in carbon dioxide reduction studies relating to the construction industry. Studies of carbon dioxide reduction throughout the building life cycle are reviewed and discussed, including those relating to green building design, innovative low carbon dioxide materials, green construction methods, energy efficiency schemes, life cycle energy analysis, construction waste management, reuse and recycling of materials and the cradle-to-cradle concept. The review provides building practitioners and researchers with a better understanding of carbon dioxide reduction potential and approaches worldwide. Opportunities for carbon dioxide reduction can thereby be maximised over the building life cycle by creating environmentally benign designs and using low carbon dioxide materials.
