Abstract

Purpose

This paper aims to explore UAE's transition towards circular economy (CE) through construction and demolition waste (CDW) management in the pre-construction stage. The extent of circularity is assessed by five key aspects of CE, such as policies and strategic frameworks, design for waste prevention, design for disassembly or deconstruction, use of prefabricated elements and CDW management plans.

Design/methodology/approach

Multiple case studies were conducted in the context of the Dubai construction industry (UAE). Three significant and unique construction projects were selected as the cases. Semi-structured interviews were carried out to collect data, and the thematic analysis technique and NVIVO 12 software were used for data analysis.

Findings

Findings reveal several positive initiatives towards CE in the UAE context; yet it is identified that the transition is still at the initial stage. Selected case studies, the best-case scenarios of UAE (i.e. influential cases), demonstrated adequate measures in relation to four key CE aspects out of five. For instance, (a) policies and strategic frameworks such as lean standards, green building standards and standards developed by the local authorities, (b) design for waste prevention (e.g. adherence to the 3R principle, and construction planning with BIM), (c) use of prefabricated elements and application of innovative construction technologies (e.g. 3DPC, DfMA) and (d) CDW management planning such as 3R principle were evident. However, the selected cases hardly showcase designing for disassembly or deconstruction.

Research limitations/implications

The existing CDW practices are mostly conventional, as most constructions in UAE are procured through conventional building materials and methods. Therefore, there is a necessity of encouraging CE principles in CDW management. Even though the transition towards CE was evident in four key CE aspects out of five, the UAE construction industry has yet to adopt more effective CE-based CDW management practices to accelerate the circularity. Hence, it is necessary to enforce standard waste management guidelines, including the 3R principle, to standardise CDW management in UAE and encourage construction practitioners to adhere to CE principles.

Originality/value

The findings of this study provide valuable insights for decision-making processes around CDW management towards a CE. This paper contributes to the literature by bridging the CE concept with CDW management in the pre-construction stage. The study provides insights for industry practitioners for planning CE in terms of policies and strategic frameworks, CDW management planning, construction planning and application of innovative construction technologies.

Abstract

Purpose

This study aims to identify in literature the role of construction stakeholders in the implementation of circular economy (CE) in the construction industry (CI). This study also sought to identify the status quo and research trend, “hot themes”, areas requiring more research and future research direction of stakeholders’ role in CE implementation in the CI.

Design/methodology/approach

A literature search was conducted using the Scopus search engine, augmented by Google Scholar to produce 50 relevant articles for the identification of stakeholders’ roles using content analysis. The scientometric study was undertaken using VOSviewer on 42 articles obtained from Scopus search to identify the status quo, “hot themes”, knowledge gaps and future research direction of the role of stakeholders in CE implementation.

Findings

Through content analysis, the identified roles of government as a stakeholder are to develop efficient policy instruments, legislation support and financial investment in research and development activities that will promote the smooth implementation of CE. The role of academia/research is to engage in research aimed at investigating both the short-term behaviour and the durability of recycled materials and products. In addition, the roles of professionals in the consultant/design/procurement team are to design with life cycle assessment and reused materials, design for deconstruction and disassembly, etc. The role of the user/consumer is to ensure knowledge diffusion and awareness exchange that recognize the available opportunities for long-term material usage (including repair, reuse, refurbishment and recycling). The research status quo identified from the scientometric analysis include how stakeholders can come up with innovative ways in demolition that will ensure that more of the materials can be reused. Stakeholders should focus on enacting policies and laws that can promote the use of recycled materials in buildings, etc. Research that focuses on how to engage the various construction stakeholders to come up with specific public policy that will promote CE implementation, identifying the specific roles to be played by stakeholders during policy enactment as well as managing the environment, laws and legislations towards CE implementation. The role of stakeholders in the extension of the life span of projects, the use of strategies to minimize waste generation and standardization of building materials, components and connectors with the purpose of simplifying disassembly are the research gaps and areas for future research studies. Some of the research “hot themes” include “circular business models in the CI”, “environmental sustainability policy implementation”, “environmental, economic and social sustainability”, “policy, laws and legislations on waste management” and “environmental and industrial economics” towards CE implementation.

Practical implications

The findings from this study serve as a valuable reference for construction stakeholders to assess their specific roles as stakeholders and to identify the status quo and research trend, “hot themes”, areas requiring more research and future research directions on stakeholders’ roles in CE implementation in the CI.

Originality/value

Identifying the role of stakeholders for CE implementation is one bold step towards the achievement of CE implementation in the CI.

Abstract

Purpose

The paper aims to provide managerial recommendations for implementing circular economy (CE) principles in both organizational and interorganizational contexts, including when using digital tools, such as building information modeling (BIM) and blockchain. Drawn from the construction sector in the Netherlands, the findings can be generalized to similar sectors where a company may receive multiple inputs as part of its supply chain augmented by digital technologies.

Design/methodology/approach

Design addresses the research question: what are the strategic and tactical approaches of organizations on the CE pathway? Sub-questions target initiatives pursued by participants, and look toward information, roles and functions for supporting the CE process. Applying a multiple-case study approach (21 semi-structured interviews with 29 participants) the paper explores strategic initiatives of construction companies implementing CE pathways. The strength of the research design comes from facilitation of rich and deep qualitative insights from Netherlands-based managers embedded within global supply chains contributing to conceptual mapping. A limitation is data from one country (though representing both national and multinational companies).

Findings

Interviewed managers share guidance for production-related construction companies anchored in materials and product design. Recommendations include to (1) develop both internally and externally the awareness of CE amongst leaders, (2) communicate with internal and external stakeholders for shared vision across the supply chain, (3) start with pilot projects, and (4) ensure product data-integration for CE business models through computer modeling and blockchain for decision-making processes, choices of materials, business model coordination and product (re)design. Continuous learning about CE roles and responsibilities amidst organizational process restructuring is required throughout linear to CE transitions. Extending the time for the CE principles evaluation process would allow for reconsideration of decisions made for CE implemented projects.

Originality/value

A novel CE gameplan with a hurdles and recommendations checklist provides an operational interface with decision making points between internal factors for the host organization and external supply chain partners.
