“…Government has a key role to play in this regard. According to Aleksanin (2019), attention of government authorities should be focused toward appointing separate bodies to coordinate material and information flows across all RLSC actors. The negative impact of not having such bodies is evident in countries, such as Vietnam and China, where the lack of collection of C&DW information at a centralized level has resulted in poor waste recovery efforts (Kim et al, 2020;Wu et al, 2016).…”

“…It is also the responsibility of the government to ensure enforcement of regulations by establishing systems of supervision to oversee all operations of the RLSC, clarify responsibilities of individual actors, and avoid conflicts (Liu et al, 2020b). Separate bodies can be appointed by the government to oversee the DW management process (Aleksanin, 2019). According to the author, these specialized bodies should be tasked with coordinating material and information resources by integrating the functions of all RLSC actors in terms of quantity, location, and timing.…”

Diverting demolition waste toward secondary markets through integrated reverse logistics supply chains: A systematic literature review

Construction industry has adopted reverse logistics (RL) concept to manage high volumes of demolition waste (DW). However, DW RL supply chains (RLSCs) were found to be suffering from uncertainties, information deficiencies, and uncoordinated material flows. Improving supply chain integration (SCI), specifically external integration, across DW RLSCs was identified as a possible solution to overcome such problems. Despite this, studies that focus on external integration in DW RLSCs are limited. Using a systematic literature review (SLR), this study explores external integration in DW RLSCs. Sixty-six articles from three databases published between 2006 and 2020 were subjected to descriptive and content analysis. Arrangement of material, information, and financial flows across DW RLSCs, inhibitors of external integration, and potential measures for improving external integration were analyzed. Accordingly, material, information, and financial flows across DW RLSCs were mapped, and inhibitors of external integration, along with potential measures for improving external integration were identified. As the key outcome of this SLR, these findings were developed into a conceptual framework, which shows the main factors that inhibit and improve external integration in DW RLSCs. The framework will be useful in guiding further empirical research and informing industry practice. Several future research directions are also proposed to expand knowledge around the research domain.

“…These activities generate massive amounts of CDW, causing environmental degradation, resource depletion and land deterioration (Islam et al , 2019). Therefore, there is a pressing need to implement an efficient and effective CDW management strategy that will lead to economic gains and protect the environment (Aleksanin, 2019).…”

PurposeThere have been numerous efforts to tackle the problem of accumulated construction and demolition wastes worldwide. In this regard, this study develops a model for identifying the optimum fleet required for waste transportation. The proposed model is validated through a case study from the construction sector in New Cairo, Egypt.Design/methodology/approachVarious fleet combinations are assessed against the time, cost, energy and emissions generated from waste transportation. Genetic algorithm optimization is performed to select the near-optimum solutions. Complex proportional assessment and operational competitiveness rating analysis decision-making techniques are applied to rank Pareto frontier solutions. These rankings are aggregated using an ensemble approach based on the half-quadratic theory. Finally, a sensitivity analysis is implemented to determine the most sensitive attribute.FindingsThe results reveal that the optimum fleet required for construction and demolition wastes (CDW) transportation consists of one wheel loader of bucket capacity 2.5 cubic meters and nine trucks of capacity 22 cubic meters. Furthermore, consensus index and trust level of 0.999 are obtained for the final ranking. This indicates that there is a high level of agreement between the rankings. Moreover, the most sensitive criterion (i.e. energy) is identified using a sensitivity analysis.Originality/valueThis study proposes an efficient and effective construction and demolition waste transportation strategy that will lead to economic gains and protect the environment. It aims to select the optimum fleet required for waste transportation based on economic, social and environmental aspects. The usefulness of this study is establishing a consensual decision through the aggregation of conflicting decision makers' preferences in waste transportation and management.

“…However, Adewuyi, et al [9] revealed that the levels of material wastes generated on-site are in excess of estimator's allowance for some materials studied. Therefore, this study surveyed the factors influencing waste generation in building projects across southwestern states of Nigeria [12][13][14][15][16][17][18][19].…”

The study was aimed to assess the factors influencing waste generation in buildings project in southwestern, Nigeria. The study randomly sampled 261 professionals through a questionnaire survey. Tables and figures were used to present the collected data and ranking and percentage were used to analyze the data collected. It was revealed that Design (Frequent design changes and poor design) lack of early contractor involvement, last-minute client requirement, engagement of inexperience designer, undefined project brief, poor design quality are the most important factors that influence l waste generation during buildings project. It was recommended that site operatives and craft men should be equipped with waste minimization knowledge, they should carry along in every management decision regarding waste management plan development as a major player on sites.
