Systematic review on stakeholder collaboration for a circular built environment: Current research trends, gaps and future directions

Abstract

Construction is one of the most impactful sectors in the use of resources, while having a complex network of stakeholders. To drive towards sustainable development, implementing circular economy (CE) principles in construction projects by connecting stakeholders has become a priority. This research explores the current trends in CE-research in construction and identifies gaps for future directions in connecting stakeholders for CE. Hence, a systematic literature review (quantitative and qualitative) was undertaken. The quantitative analysis identified a gradual increase of CE research in construction. The qualitative content analysis revealed that there is a tendency to adapt various models/frameworks, actions for CE adaption, strategies for stakeholder collaboration, and, digital technologies to connect stakeholders for CE. Lack of promoting CE is a key challenge that needs to be addressed for efficient stakeholder collaboration. Blockchain, could be an enabler for effective stakeholder collaboration for CE in construction and will be the way forward.
