Facilitating a transition to a circular economy in construction projects: intermediate theoretical models based on the theory of planned behaviour

A transition to a circular economy (CE) is a sociotechnical phenomenon that relies on adopting innovative methods and technologies, as well as changes in behaviour across the construction supply chain. Although a lot of ground has been covered on developing methods and technologies, there is little research on stakeholders’ change of behaviour. Informed by an underlying framework, the theory of planned behaviour, a comprehensive literature review discusses several conceptual models to establish the interrelationships between barriers and drivers to managing a transition to CE – and their underlying causes. The findings offer a comprehensive point of reference for identifying factors that affect CE adoption, and lay a solid foundation for future research into CE adoption and managing a CE transition where the intermediate theories presented can be validated through empirical research.
