2021 Owens Corning Sustainability Report | Reducing Our Environmental Footprint | Air Quality Management | 161 Our Air Quality Roadmap Owens Corning’s plan to reduce intensity of VOC and PM2.5 emissions includes the following strategies: Short-term Strategies ■ Maximize controls efficiency through equipment and maintenance optimization. ■ Leverage LCAs and use principles of product stewardship when developing new products or improving existing products. Medium-term Strategies ■ Explore and implement process changes to lower emissions from our manufacturing process. ■ Drive product innovations that reduce emissions from our products. ■ Explore and test innovative air emissions control technologies. Long-term Strategies ■ Design products to lower emissions from both the manufacturing process and product use phase. Air Quality Management Strategies Regardless of whether we have specific targets for various types of air emissions, we understand what will be required to reduce them. Here are some of the air quality management strategies we have in place: ■ Product and process innovation Designing products with an eye toward lowering emissions can have a significant impact. One example of this is the conversion of our residential EcoTouch ® insulation, which helped drive our success toward our 2020 targets. By shifting to a starch-based, formaldehyde-free binder, we significantly reduced the emission of VOCs and PM2.5. In addition, we will continue to use the principles of product stewardship to evaluate use-phase impact during product development. One example of this is our PINK Next Gen™ Fiberglas™ insulation, launched in August 2021. This product offers a wide range of sustainability benefits, including Underwriter Laboratories GREENGUARD ® Gold certification for low volatile organic compounds. ■ Optimization of equipment We are working to ensure that the equipment we use to control emissions — incinerators, dust collectors, scrubbers, etc. — are operating as reliably and efficiently as possible. As Total Productive Maintenance is deployed across our sites, employees are using these principles to ensure equipment is run optimally. ■ Consistent Testing To ensure consistency of testing for air and PM2.5 emissions, we have experts who oversee testing at our facilities, and then review and verify the results and findings. In addition, our experts partner with our business units and plants to ensure that we understand the impact of potential changes to our processes and plan accordingly for future events.
