Purpose The purpose of this paper is to explore the synergies among reverse logistics supply chain (RLSC), quality management (QM) and information management (IM) concepts to enhance the effectiveness of demolition waste management (DWM) practices. Design/methodology/approach A systematic literature review was conducted using 70 articles published between the years of 2006 and 2017, which were subjected to descriptive and thematic analysis. Findings The descriptive analysis established that the RLSC concept was dealt within the majority of the publications (61 per cent), followed by concepts related to quality in RLSC (24 per cent). Only 14 per cent of the articles were based on IM concepts related to RLSC. Quality and information are interrelated in the effective implementation of RLSC. The thematic analysis demonstrated that there is a need for using quality parameters in a regulatory environment in an information-based environment. Based on the findings, future research directions were developed. Research limitations/implications The study encourages researchers to identify novel directions by combining these three concepts. The study developed a future research agenda regarding use of building information modelling (BIM) for existing buildings under novel technologies; analysis of secondary market demand and supply; and assessment of cost and safety management with quality in a BIM-enabled environment. Practical implications The practical implications include the application of sustainable management principles based on stakeholders and the regulatory environment. Originality/value Integration of the three concepts is an emerging area. This integration developed a robust approach to achieve QM in RLSC operations under a sound information flow enabling the optimisation of DWM.
Purpose The purpose of this paper is to explore the synergies between post-end-of-life of building (PEoLB) concepts and operations to achieve sustainability. Design/methodology/approach A systematic literature review (SLR) was conducted using 65 articles published between 2006 and 2017, and it has been subjected to descriptive and thematic analysis. Findings The descriptive analysis revealed that the majority of the articles were about (60 per cent) PEoLB operations, followed by (23 per cent) PEoLB concepts. Only 17 per cent of the articles have dealt with PEoLB-related strategic approaches. The thematic analysis elaborated on the literature development; interrelationships between PEoLB concepts and operations; impediments of introducing sustainability on these operations, remedial measures and information-based strategic approaches to achieve sustainability. Based on the findings, a conceptual framework for sustainable PEoLB operations is proposed. Furthermore, four areas of potential future research are discussed. Research limitations/implications This study presents a future research agenda including best practices to plan PEoLB operations and the development of optimisation models, risk management and information-based strategic approaches. Practical implications The proposed conceptual research framework triggers and nurtures potential pathways to introduce sustainable PEoLB operations under sound information flow. This could create a basis for future empirical studies in filling the identified gaps in literature. The framework could also assist practitioners in mitigating risks associated with transportation, storing and contamination of salvaged materials through enhanced information flow. In addition, the framework provides some managerial guidance to organisations seeking ways of establishing sustainability during reverse logistics (RL) operations. Originality/value This paper presents an SLR of an emerging area of research that encapsulates closed-loop supply chain through sustainable RL operations. The study highlights the interrelationships between PEoLB concepts and operations. It develops a robust approach to effectively manage the PEoLB operations underpinned by a sound information flow to facilitate sustainability.
The circular-economy-related research has exponentially increased in recent years. The literature shows that circularity indicators represent a timely topic that requires an in-depth analysis. However, the trends and gaps in the literature in the area of the circular economy have not need analysed in depth. This study uses a scientometric analysis as the research methodology to examine the current literature on circularity and circular economic indicators. The publications were extracted from the Web of Science and were published until the end of the third quarter of 2022. The scientometric analysis was conducted using VOSviewer software to map the relationships between the 1117 articles selected on the topic. The findings revealed that the most productive author and university were Jorge de Brito and Delft University of Technology in the Netherlands. The overlay visualisation of the keywords identified a notable shift in research themes from dynamics, frameworks, models, and design in previous years to economy, barriers, and strategies in the current research context. The overlay visualisation of the keywords identified trending research hotspots within the current research context. This study is the first holistic and global overview of circularity and circular economic indicators in the construction context and identifies a critical need for further research to understand circularity and circular economic indicators under co-occurrence analysis conditions. This study offers academics, policymakers, and other circularity activists a guide for future research and valuable insight into circularity and circularity indicator themes.
PurposeThe reverse logistics supply chain (RLSC) for demolition waste management (DWM) is a complex process that inherits significant interdependent risks. However, studies on the RLSC have not explicitly identified the risks of its inter-relationships by disentangling their effects on operational performance. Accordingly, this paper aims to identify and assess the inter-dependencies of the risks in the RLSC to improve quality-related operational performance.Design/methodology/approachA sequential exploratory mixed-method research approach, consisting of qualitative and quantitative methods, was employed. The qualitative approach involved 25 semi-structured interviews, whereas the 18 subsequent structured interviews were conducted with stakeholders in the entire RLSC as part of the quantitative method. These were used to identify the cause and effect relationships of the identified risks. The data were analysed using thematic analysis, and the Bayesian belief network (BBN) technique was used to develop a conceptual risk model.FindingsIn total 20 risks in four RLSC sub-processes, namely, dismantling and on-site process, off-site resource recovery process, marketing of secondary products and residue disposal, emerged. Among cause and effect relationships of identified risk factors, inferior quality of secondary products was found to have the strongest relationship with customer satisfaction. Under-pricing of dismantling job, improper landfill operations and inadequacy of landfill levy are independent risks that initiate other risks down the supply chain. The aggregate effects of these risks affect customer dissatisfaction of the end-product, as well as health and safety risks in on-site, off-site and residue disposal.Research limitations/implicationsThis study only identify the cause and effect relationships of the identified risks within the RLSC for DWM operations. It has not targeted a specific construction material or any secondary production, which could be practiced through a case study in future research.Practical implicationsThe results encourage the investigation of RLSC process quality by maintaining the relationship between recycler and customer to enable a safe workplace environment. Hence, the role of relevant practitioners and government is inseparable in supporting decision-making. Future research could discuss the impact of those inter-related risks in relation to time- or cost-related operational performance criteria.Originality/valueThis study contributes to the field through presenting the first major study on the identification and assessment of the inter-dependencies of the risks in the RLSC in South Australia. The RLSC process mapping had been identified as a tactical and operational management approach. However, the risk management process is a strategic management approach. Therefore, the integration of both process mapping and the risk management approaches in one platform is germane to construction management research.
