2021 Owens Corning Sustainability Report | Overview | Summary & Highlights | 18 Photos: PINK Next Gen™ Fiberglas™ (left) WindStrand ® (center) Trumbull ® Asphalt (right) Product Innovation & Stewardship By 2030, we intend to offer the most recognized and preferred products for sustainability. ■ To meet this ambitious goal, we are striving to implement strategies that deliver the lowest impact with respect to embodied carbon among all available options. ■ We will design our products for recycling or reuse at their end of life while using Life Cycle Assessments as our guide. We will ensure our products contain a high percentage of recycled and renewable materials. In addition, we will collaborate with our suppliers to increase transparency regarding the raw materials we use in our products. This helps us understand and control the full impact of our products — and enables us to share that information with our customers so they can do the same. ■ Product innovation is essential to all three of our core businesses — Composites, Insulation, and Roofing — as we develop new products and applications across a growing range of key market segments. This innovation is inspired by the needs of our customers and addresses growing global trends. By collaborating closely with stakeholders, we can deliver sustainable solutions that meet the demands of the marketplace. ■ Product stewardship is a driving force behind our approach to innovation. As we develop new products or improve existing products, everyone involved understands that they share the responsibility for reducing those products’ environmental footprint and increasing its product handprint. At every point in a product’s life cycle, we must consider its potential environmental impact — and demonstrate transparency regarding the sustainability of our products. To mitigate that impact, we work to ensure our products are sustainably made, using our stringent stewardship process to evaluate 100% of our new and significantly modified products for EHS impacts and our gated innovation process to evaluate potential life cycle impacts. Recent innovations in our portfolio include the following: ■ PINK Next Gen™ Fiberglas™ insulation , launched in 2021, offers the highest recycled content in the industry, and it is certified made with 100% renewable electricity through the use of power purchase agreements. In addition, it has earned Underwriter Laboratories GREENGUARD ® Gold certification for low volatile organic compounds. ■ PAROC ® Natura insulation is a carbon-neutral line of stone wool insulation that uses low-carbon melting technology, green electricity, recycled waste materials, new technologies, and purchased carbon offsets to minimize the amount of CO 2 e emitted during the manufacturing process. ■ FOAMULAR ® NGX™ insulation, introduced in 2020, features a proprietary blowing agent that is optimized to demonstrate greater than 80% reduction in embodied carbon, compared to legacy FOAMULAR ® insulation products. The product meets and exceeds stringent regulations going into effect in 2021. ■ WindStrand ® allows wind blade manufacturers to use 30% fewer layers of material in the blade molds, while delivering the same quality and performance as standard fabrics. This in turn represents a 50% savings in labor and production time for the blades. In March 2021, we introduced WindStrand ® 4000, as well as Ultrablade ® 2 and Ultraspar™ 2, three high-performance materials that help wind blade manufacturers develop longer, stiffer, stronger blades, which helps make wind energy more cost-effective. ■ Trumbull ® Asphalt has made significant strides over the last five years to reduce the number of oxidized products we produce for external asphalt markets. In 2015, 8% of our products were non-oxidized. Today, approximately 50% of the products we produce for the external asphalt business are non-oxidized, requiring less energy, lower temperatures, and fewer emissions. This has resulted in a 3% improvement in material efficiency across the 12 asphalt plants in the network.
