Abstract
Purpose
Offsite construction (OC) is an efficient method to reduce waste in the construction industry from a circular economy perspective. Yet, its uptake is subdued by the ambiguities around its supply chain. Hence, the purpose of this study is twofold: to identify the OC project delivery models, the limitations in their procurement approach to facilitate the resilience of the supply chain and interventions to promote supply chain resilience (SCR) and to identify the gaps in the existing procurement process and propose further research areas that implement strategies to improve SCR.
Design/methodology/approach
The study was conducted as a systematic literature review. In total, 41 peer-reviewed research papers published between 2013 and 2023 were shortlisted through the preferred reporting items for systematic reviews and meta-analysis guidelines. A descriptive analysis was conducted, followed by a thematic analysis.
Findings
The descriptive analysis reveals that the emphasis on digitising OC has shifted to transforming the business model, procurement and supply chain with a human-centric view. In thematic analysis, the predictability of the SC partners and the probabilities of evaluating the prospects are revealed as arbitrary characteristics in the current procurement strategies. Rewarding collaborative relationships among SC partners and incorporating provisions to postpone the module delivery are some interventions to promote flexibility. Drafting comprehensive and effective contracts that address transparency issues and facilitating the need for continuous development of capabilities through procurement are among the further research avenues proposed.
Originality/value
This study is a precursor demonstrating the potential of the procurement process to implement the decrees of SCR for better goal congruence of the OC supply chain.

Abstract
Purpose
This paper aims to synthesise the latest literature on supply chain operations of offsite manufacturing in the construction industry to identify and evaluate the uncertainties at each stage of the offsite construction supply chain (OSC-SC) to compile contributions to knowledge and thereby determine the future research directions to improve supply chain resilience (SCR).
Design/methodology/approach
The study was conducted as a systematic literature review. In total, 99 peer-reviewed journal papers published between 2015 and mid-2022 were shortlisted and analysed through the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.
Findings
The bibliometric analysis revealed that the research focusing on supply chain issues and developing best practices in offsite construction adopt case study approaches to investigate the research problems comprehensively. The content analysis revealed the lack of up-to-date knowledge in the construction workforce regarding OSC; low preparedness for the changes brought by the SC uncertainties; the lack of a proper procurement model for OSC; lack of end-to-end visibility of the supply chain to identify uncertainties and lack of national or government standards on OSC-SC, as some of the key problems instigating the identified the uncertainties.
Originality/value
This study clarifies the current knowledge by systematically presenting uncertainties at each stage of the OSC-SC. Moreover, it provides a framework and proposes that future research should focus specifically on individual/team, organisational, supply chain/network and sector/national/supranational levels to improve SCR.

Abstract
Purpose
The uptake of reprocessed construction materials (RCMs) derived from demolition waste (DW) is limited, which questions the long-term sustainability of DW reverse logistics (RL). To address this gap, the current study focused on identifying informational and structural interventions to promote the uptake of RCMs among Australian construction professionals (CPs).
Design/methodology/approach
Following a qualitative research approach with thirty-one semi-structured interviews, the study explored potential interventions that can drive broader RCM usage. The study's strength lies in the in-depth qualitative insights gathered through extensive interviews with CPs experienced in using RCMs.
Findings
Sixteen informational and structural interventions to promote the uptake of RCMs were identified and mapped against the industry levels at which they should be implemented. RCM suppliers should focus on improving material quality, supply and marketing while minimising material costs. Governments should encourage using RCMs through incentivisation, supportive legislation and approval processes. The significance of awareness building and research was also recognised, which requires the collective efforts of suppliers, governmental and non-governmental bodies and educational institutes.
Originality/value
Despite the talk around sustainable consumption, the actual walk towards this is limited from a construction perspective, as seen through the low uptake of RCMs. This study attempts to bridge this mismatch by outlining informational and structural interventions that would drive CPs to walk the talk and use RCMs for construction applications. While most studies on DW RL have focused on improving waste recovery processes, this study takes a less-trodden path and explores the potential for developing markets for RCMs.

The purpose of this paper is to investigate risk propagation and resilience in the agribusiness supply chain (ASC).
Abstract
Purpose
The purpose of this paper is to investigate risk propagation and resilience in the agribusiness supply chain (ASC).
Design/methodology/approach
The paper undertakes a systematic literature review (SLR). Overall, 94 articles from six databases published between 2000 and 2022 underwent descriptive and thematic analysis.
Findings
There is a lack of research on risk propagation and resilience in the ASC for more than two decades. Accordingly, this research fills the gap in the extant literature by advancing the construct of risk propagation and resilience in the ASC and developing a framework proposing directions in risk propagation and resilience in ASC research.
Research limitations/implications
Firstly, only the Web of Science and Scopus databases were mostly used as primary sources while other databases were used as secondary sources to validate search results. Secondly, SLR is based on the peer-reviewed articles, books and conference papers; other non-academic sources relevant to the topic were not included in this paper.
Originality/value
The paper offers a set of constructs for understanding risk propagation and resilience in the ASC, develops a framework proposing directions in risk propagation and resilience in the ASC research and recommends three key themes for future research directions, namely, keep updated with recent constructs of risk propagation and resilience in the ASC, conduct case studies based on empirical studies to determine the current risk dependency and propagation in the ASC and conduct case studies based on empirical studies to determine resilience and sustainability in the ASC.
