Infrastructure development carries a significant environmental footprint, driven largely by materials that are resource-intensive, carbon-intensive and usually locked in early on a project. Sustainable procurement builds environmental, social and governance considerations into every procurement decision, what to procure and who to procure it from, and its benefits go beyond emissions reduction, improving project efficiency and reducing ownership and operation costs over time.

Through collaboration with industry partners, universities and major infrastructure clients, we've developed an interactive tool built with a series of assumptions allowing users to calculate a Material Circularity Indicator (MCI) with readily available infrastructure design and delivery inputs.

Material circularity has become a key focus for infrastructure, driven by growing policy, procurement and sustainability expectations. The direction is clear: circularity is becoming an expectation across major projects. Yet despite this momentum, many organisations still struggle to measure and demonstrate circularity in a consistent, defensible way.
