2021 Owens Corning Sustainability Report | Expanding Our Product Handprint | Circular Economy | 94 In many ways, our commitment to the circular economy model is at the center of our sustainability journey. It’s connected to our waste management strategies, our approach to product innovation and stewardship, and ultimately our plans for sustainable growth. Our circular economy team has brought a streamlining of our various circular economy initiatives, helping us focus our actions at our sites around the world, and they will be integral as we continue to develop our circular economy model. This will require the establishment of effective processes and the cooperation of our entire value chain as we develop innovative products and cultivate the markets in which they will be used throughout their life cycles. With this team in place, Owens Corning is now in an even better position to invest in the capabilities needed to achieve our circular economy ambitions, from people to resources to emerging technologies. We have begun a pilot program to build capability for recycling within our Composites business with the aim of enabling circularity. We are also investigating the potential in processes such as chemical recycling, which could prove valuable as we try to perform tasks such as separating fibers from resins and chemicals. This level of investment demonstrates our dedication to this bold — and very necessary — rethinking of the way we do business.
