2021 Owens Corning Sustainability Report | Expanding Our Product Handprint | Product Innovation & Stewardship | 99 SPEAKING OF SUSTAINABILITY With more than 30 years’ experience in the asphalt industry — over 10 of them at Owens Corning — Laurand Lewandowski has insights into the innovations that have shaped where we are today and the trends that will be guiding us in the future. Laurand has been focused on sustainability for years, and his expertise has helped move Owens Corning toward our goals in many areas. Here, he discusses some of the key elements of his work in sustainability, as well as the collaborations required to achieve our aspirations.

And so we have to be holistic about what steps that takes, not only from the innovation side, from the science and technology area, but also from the business perspective, building out that ecosystem so that you have a sustainable process for achieving our goals. On new developments in specialty paving We entered the specialty paving business in 2015 and targeted some of the more niche areas that we could bring our technology strengths to. We had a couple of contractors that were very progressive and wanted to look more at recycling, so we partnered with them to make an asphalt mix design, which incorporated not only RAP (reclaimed asphalt pavement), but also recycled asphalt shingles. Working with our roofing plants' manufactured shingle waste, third parties who process those shingles, and then the hot mix asphalt contractor and our asphalt plant, we were able to successfully divert over 15,000 tons of shingle waste from landfill. By finding a key contractor that recycled the material and made a good performing pavement, we have a stepping stone to getting that approved by departments of transportation in the future. On working with the Asphalt Roofing Manufacturers Association (ARMA) I chair ARMA’s Asphalt Roofing Recycling Committee, and it’s an exciting time because ARMA is putting out a recycling statement that will be defining the vision of the industry going forward, so I have an opportunity to help craft that message for Owens Corning. This aspiration goal will then help focus the industry on the long-term diversion of shingle waste from landfill and back into circular economies. We have to be holistic, from the innovation side and from the business perspective. ” “ Laurand Lewandowski Director, Asphalt Innovation
