This document summarizes a panel discussion on moving from a linear to a circular economy in the cement sector. It introduces the panel members and moderator and provides context on the growth of global materials extraction. It then defines the concepts of a linear take-make-use-dispose model versus a circular economic model where resources are continually reused and recovered. The document outlines challenges to achieving a circular economy and strategies discussed by the panel, including design for material recovery and initiatives by the Cement Sustainability Initiative to advance core sustainability programs, develop metrics, collaborate across industries, and work with policymakers.

Conclusions
Raising awareness
the language of the Circular Economy can be alienating to some
Further advancing core programmes
reduce waste, resource efficiency, energy efficiency,
use of alternative fuels and raw materials, water conservation
Developing metrics
to drive further improvements and celebrate success
Collaborating across the value chain
to identify further opportunities where cement and concrete can make a difference
Working with policy makers
to remove barriers
