    Blockchain Integration for Circular Economy Adoption in Steel Construction
    (Emerald Group Publishing Ltd, 2026) Bilgin, Gozde; Birgonul, M. Talat; Akcay, Emre Caner; Dikmen, Irem; Demir, Berkan
    PurposeThe circular economy (CE) is an economic model aimed at minimizing waste and optimizing resource use by extending lifecycles through recycling, reuse, and other strategies. This shift from the traditional linear model (take-make-dispose) is crucial for a more sustainable and resilient built environment. Given its environmental impact, the steel construction industry holds significant importance in driving sustainability and CE efforts. This study aims to explore the potential of a blockchain(BC)-based framework to overcome barriers hindering the adoption of CE principles within the industrial steel construction sector, thereby promoting sustainability and circularity in the built environment.Design/methodology/approachA conceptual BC framework is proposed to enable effective recording, storing, and sharing of process-related data among stakeholders throughout the lifecycle of construction materials. The framework's validity is assessed through a focus group study conducted at a steel construction company, involving expert evaluations.FindingsExpert evaluations indicate that the BC-based framework can significantly enhance CE adoption by improving information flow, raising awareness, and fostering collaboration among ecosystem participants.Originality/valueThe study introduces an innovative application of BC technology tailored for the steel construction sector to address specific CE barriers, offering a novel approach that facilitates digital and sustainability transitions.

    Ensuring Circularity Through Outsourcing Decisions in Solar Photovoltaic Supply Chains
    (Springer, 2025) Erol, Ismail; Peker, Iskender; Benli, Tolga; Ar, Ilker Murat
    Because solar photovoltaic (SPv) panels have seen such significant cost reductions in recent years, it has proven to be by far the most dynamic forms of renewable power generation. However, the transition from linear to circular is also crucial for building sustainability in SPv supply chains. The circular economy (CE) is appealing in part because of its ability to bring economic and environmental development objectives together to ensure sustainable production and consumption. To aid in the shift to a more circular economy, several circular-based strategies for various functions such as procurement can be developed. In this study, critical success factors (CSFs) to ensure circular outsourcing structure in SPv supply chains are identified and scrutinized. To achieve this, a multi-criteria-based methodology is proposed. The findings of this study argue that understanding the actual implications of not converting to circular outsourcing (C12) is the most significant cause CSF. This study also provides several implications. © 2025 Elsevier B.V., All rights reserved.
