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.

As a major transport infrastructure project with ambitious sustainability targets, METRONET’s Morley–Ellenbrook Line required a coordinated approach to carbon management, materials assessment and ratings performance across multiple project phases and disciplines.
