Abstract

Purpose This paper investigates the impact of green construction procurement practices (GCPPs) on circular economy (CE) success by identifying environmentally sustainable procurement practices that can promote a CE in the construction industry. The goal was to promote circularity in construction through GCPPs. Design/methodology/approach A quantitative research approach was adopted and purposively selected 100 respondents for a cross-sectional questionnaire survey. Data from the questionnaire survey were analysed using mean score ranking, One-sample t-test and regression analysis. Findings The study found that using on-site systematic waste management, project stakeholder commitment and support for green practices and environmental requirements in technical specifications, significantly impact CE success in construction, with a 12.8% variance in CE when green procurement is practised. This implies that GCPPs have positive repercussions on CE success, where the CE success is expected to change as GCPPs levels increase. Practical implications The study provides insights into green procurement, promoting its use in infrastructure development and aiding clients, particularly in the government sector with insights into the challenges and practices involved in green procurement. Practitioners can also benefit from better implementing CE strategies to draft and manage contracts for infrastructure projects that prioritize circularity. Originality/value The limited impact of GCPPs on advancing CE principles in construction suggests policy and practice must strengthen procurement requirements to fully leverage spending and drive the sector’s transition towards a circular model. Also, novel insight is provided into the most effective types of GCPPs for promoting CE success, aiding policymakers in optimizing construction procurement strategies.
