Mega-Projects in Construction: Barriers in the Implementation of Circular Economy Concepts in the Kingdom of Saudi Arabia

Buildings, Journal Year: 2024, Volume and Issue: 14(5), P. 1298 - 1298

Published: May 4, 2024

The construction sector has been subjected to scrutiny due its propensity for waste generation and the extensive utilisation of finite natural resources. In response these concerns, a transition towards novel conceptual framework known as circular economy (CE) advocated. Nevertheless, integration CE principles within domain encounters numerous impediments advancement. Despite scholarly recognition challenges, scant research devoted elucidating intricacies associated with planning execution large-scale projects, particularly developing nations such Kingdom Saudi Arabia (KSA). This paper intends fill this gap through identification ranking those barriers encountered when trying implement during in KSA. To end, comprehensive literature review was completed, alongside survey conducted amongst 239 participants involved three mega-projects. A statistical analysis data collected carried out based on one-way variance (ANOVA). Following this, relative importance index (RII) established rank 24 categorised major sample. findings revealed lack regulation sector, education training, little awareness guidance subject, absence an incentives policy primary adopting present study endeavours enhance comprehension regarding attendant challenges implementation. overarching objective is provide insights that can inform decision-making processes, thereby facilitating development robust mitigation strategies adoption best practices.

Green servitization, circular economy, and sustainability a winning combination analysis through hybrid SEM‐ANN approach

Business Strategy and the Environment, Journal Year: 2024, Volume and Issue: unknown

Published: Sept. 12, 2024

Abstract To accomplish the 2030 Sustainable Development Goals (SDGs), manufacturing industry faces significant hurdles, particularly in embracing green servitization and circular economy ideas confronting dearth of research on for sustainability. fill this lacuna, study examines role promoting practices (CEPs) sustainability Malaysian firms. A robust framework has been forged based natural resource‐based view (NRBV) theory. Data from a survey 251 firms (Malaysian Japanese) were collected analyzed using hybrid methodology that included structural equation modeling artificial neural network (SEM‐ANN). The findings SEM highlight positively promotes CEP sustainable performance. Furthermore, mediating between ANN results indicate is dominant predictor dimensions. Unlike prior theoretically assumes all relationships are linear, nascent successfully validated there exists nonlinear relationship NRBV framework. Based outcomes, contributions, practical implications, future avenues have discussed.

Purpose The resource-intensive nature of the Construction Industry (CI) and resultant Environmental Impacts (EIs) calls for adoption a Circular Economy (CE) in construction demolition waste (CDW) management. In recent times, CDW management CE have attracted attention from researchers practitioners. However, there is lack comprehensive Scientometric analysis, specifically on CI. study aims to provide an in-depth analysis investigate overview studies global context. Further, work present various approaches strategies emerging trends. Design/methodology/approach To fill literature gap, provided intersection CE. utilized Scopus database bibliographic data retrieval.

Circular Economy Business Model in the Construction Industry: A Systematic Review

Published: Jan. 3, 2024

The construction business environment is becoming competitive and intense, Business Models (BMs) are receiving considerable attention as potential sources of sustainable survival growth. Converse to the linear economy model that industry follows, Circular Economy (CE) has create a industry, while creating in organisations. Nevertheless, traditional BMs, value often concentrated on financial for stakeholders; (CEBMs), seen more broadly by considering comprehensive range chain partners, environment, society. Hence, implementing CE requires reforms each chain. Thus, aim this paper develop conceptual organisations' adoption CEBMs their To accomplish aim, objectives twofold: (i) define concept CEBMs, (ii) map Conceptual CEBMC (Circular Model Canvas) applicable organisational context. This research adopted systematic document review, including content analysis selected papers. study contributes significantly proposing CEBMC, which organisations could successfully transform businesses from circular environments.

Industry 4.0 deployment for circular economy performance—Understanding the role of green procurement and remanufacturing activities

Business Strategy and the Environment, Journal Year: 2023, Volume and Issue: 33(2), P. 1144 - 1160

Published: Aug. 21, 2023

Abstract As regulatory authorities emphasize sustainable practices, manufacturing organizations rely on Industry 4.0 technologies to shift their business model from a linear circular economy. While intuitively this transformation seems straightforward, in reality, it is rather nuanced, thereby necessitating scholarly investigation into process‐based antecedents of economy performance organizations. This study used structural equation modeling analyze empirical data 278 Indian manufacturers. Largely, the results demonstrate that adoption does have significant effect within these organizations, owing strong influence green procurement and remanufacturing activities. Additionally, show process activities (e.g., remanufacturing) do mediate interaction between deployment performance.
