“…Ibáñez-Forés et al [70] identified circular services provided for the organisation, for instance, reverse logistics and promoting/offering shared facilities or equipment, as organisational indicators used to assess the CE. End-of-life strategies, after-sale services strategies in the design stage, after-handing, and product as a service are key performance indicators used to assess the CE in a construction project [71].…”

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

“…Life Cycle Assessment (LCA) is a crucial scientific methodological tool used to assess the environmental impacts of materials. However, its effectiveness in evaluating material circularity is hindered by several challenges, such as the lack of practical application in the design and development phase, challenges with system boundaries and impact allocation, the inability to assess the social implications of materials, and biases and inconsistencies in the results (Antwi-Afari et al, 2023). The literature review on the LCA method was carried out using the keywords ''measure* AND Circularity AND Life Cycle Assessment'' in the academic search engine Scopus.…”

Circularity has emerged as a pivotal concept in the realm of sustainable resource management and business operations. Resource exhaustion and environmental degradation propelled by globalization and the culture of consumerism have intensified the focus on the concept of the circular economy around the world. Nevertheless, the evaluation and quantification of circularity achievements remain uncommon in corporate practices. This article employs a systematic literature review to delve into circularity measurements in the managerial life cycle. Key approaches emerging from the academic literature are examined, including life cycle costing, life cycle assessment, life cycle cost–benefit, life cycle benefit analysis, and life cycle sustainability assessment. The review seeks to offer a comprehensive overview of the methodologies employed to assess circularity in corporate processes, highlighting current challenges and opportunities for effective implementation. We adopt a conceptual model of sustainable and circular life cycle management based on specific performance indicators that allow the environmental, social, and economic impact of processes to be assessed throughout the life cycle of products or services. The implementation of Sustainable and Circular Life Cycle Management from a managerial perspective could support firms to eradicate and quantify waste, preserve the inherent value of products and materials, encourage the adoption of renewable energies, and eliminate harmful chemicals.

The circular economy (CE) has recently emerged as a key strategy for promoting sustainability and reducing waste in various industrial sectors. This paper provides an overview of the definition, assessment and enhancement of circularity in general and in five key industries, including aerospace, wind energy, transportation, automotive and sports goods, by using data and information from the literature and for the section of the definitions of the CE also using information from the EC funded project “RECREATE”. The survey reviews in detail the different definitions, assessment methods and metrics used to explore and evaluate circularity, including assessment frameworks such as Life Cycle Assessment (LCA) and assessment indicators. Furthermore, it explores the challenges, possibilities and available tools for enhancing circularity, focusing on digital tools. The survey highlights the importance of a holistic and systemic approach to circularity concerning all stakeholders along the value chain. Overall, this study aims to contribute to a better understanding of the circular economy's definition, assessment, and enhancement and provides insights for future research.
