Materials are getting harder to source and more closely scrutinised, and infrastructure clients are asking sharper questions about where they come from. This article looks at what resource efficiency means in practice, from smart early decisions to measurable evidence trails, and how project teams can turn good intentions into real outcomes.

Material circularity has become a key focus for infrastructure, driven by growing policy, procurement and sustainability expectations.
