Saint-Gobain, a global leader in sustainable construction, has unveiled RenuCore by CertainTeed, a cutting-edge manufacturing technology designed to recycle asphalt shingles and divert them from landfills. This innovative process allows construction and demolition recyclers, as well as hot mix asphalt producers, to pelletize shingle waste for reuse in asphalt paving applications, promoting circular economy principles.
Originally developed by Asphaltica and acquired by CertainTeed in 2023, the RenuCore technology enhances the recycled content in hot mix asphalt while maintaining the performance of traditional paving materials. The launch aligns with Saint-Gobain’s ambitious Grow and Impact strategy, which includes a commitment to achieve zero waste-to-landfill across all its operations.
Improved Durability and Performance
The new recycling process addresses challenges related to repurposing asphalt shingles by pre-treating and pelletizing the materials. This innovative approach results in enhanced performance characteristics, such as increased resistance to rutting, shoving, and cracking. By improving the performance grade of recycled asphalt, RenuCore aims to match the durability and longevity of roads constructed with virgin materials.
Carmen Bodden, President of CertainTeed Roofing Products Group, highlighted the importance of the launch: “RenuCore reflects our commitment to innovation and cross-industry collaboration. Whether our products are used in roofing or asphalt paving, CertainTeed remains focused on delivering quality and sustainability.”
Official Launch at Industry Event
RenuCore debuted at the Construction and Demolition Recycling Association’s 10th Shingle Recycling Forum, October 29-30, 2024, in Louisville, Kentucky. The forum is a premier event for shingle recycling and featured presentations from members of the CertainTeed Roofing team.
