2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Waste Management | 181 Our 2030 waste management goals are quite ambitious, but we are confident they can be achieved through our WTL efforts and the designated resources throughout our businesses. Within this network of committed employees, we regularly share ideas, best practices, and recycling outlets across our plants, businesses, and R&D. Owens Corning has successfully diverted the majority of the waste we generate away from landfills and toward other uses. Offtake customers have found value in these materials and successful transaction agreements have been established, and we continue to find new outlets for specific types of waste streams by region. Although we have had a great deal of success diverting material from landfills, each business unit continues to have waste streams that are landfilled. In their current form, these streams are not usable in another application, and economical recycling processes typically do not exist. Our approach is to establish internal recycling for a more robust pathway to zero WTL. This approach can be seen in all three of our businesses. The waste that is sent to landfill in our Composites business consists mainly of glass fiber. This is also the case for our Insulation business, specifically in the glass and mineral wool fiber waste streams. For this reason, we are investing in technologies and processes to upgrade waste glass fibers into raw materials appropriate for remelting, and then fiberizing them into new fibers to be used within our operations. Once appropriate recycling capabilities are developed and scaled, we will have addressed two-thirds of our remaining WTL volume. Our Roofing business represents a relatively low percentage of our enterprise WTL, with shingle tear-off waste at end-of-life representing the larger landfill challenge. As advances are made in Owens Corning’s activities to build the circular economy model for our shingle products, those same technologies and systems can be leveraged to recycle the majority of the manufacturing waste from our Roofing plants. The following are among the notable waste management initiatives conducted at Owens Corning in 2021. Besana, Italy As part of their commitment to eliminating the use of single- use plastic products, the facility installed 11 water dispensers on the shop floors. Employees were also given personalized, branded water bottles, helping reduce the amount of single- use plastic throughout the plant. Granville, Ohio, U.S. The Granville Material Characterization Lab (MCL) recently underwent a team exercise to identify all lab waste streams, and they have begun to take small but impactful actions to reduce them. The MCL has been actively committed and working toward zero WTL since 2020, and they expanded their aspiration in 2021 to include a shared sustainability goal that holds individuals personally responsible for reducing lab waste. This includes committing to using reusable or biodegradable coffee cups, utensils, and plates, adding more recycling and composting bins, and working with lab customers to reduce the amount of composite materials shipped on-site for testing. The MCL is also dedicated to sharing best practices to facilitate a larger reduction in waste sitewide. In 2021, Granville also received recognition for their commitment to Kimberly-Clark’s RightCycle program, which diverts single-use gloves from the landfill. This past year, the Granville Science & Technology Center recycled over 321 pounds of gloves, compared to 185 pounds in 2020. Liversedge, U.K. As part of their commitment to reducing waste, employees at the plant in Liversedge discovered that cutter housings from one machine are compatible with another and can help cut the composite sheet effectively. Blades that had previously been scrapped can now be used beyond their previous end of life, which places Liversedge closer to their goal of zero WTL. Hässleholm, Sweden As part of their goal of achieving zero WTL, the plant in Hässleholm drew up a four-point action list in which they would: 1. Reduce waste by improving production processes. 2. Recycle all cured waste to blowing wool, using both new ad-mix equipment and the old recycling system. 3. Recycle all spinning waste via briquette. 4. Recycle all cupola dust via briquette. As a result, their WTL has gone from almost 19% in 2013 to just over 4% in 2020, and their goal of zero WTL is well within reach. Our waste management goals benefit our business as well as the environment — by reducing costs associated with transportation, disposal, raw materials, energy, time, and labor. OUR INITIATIVES
