Saint-Gobain has launched RenuCore by CertainTeed, an innovative manufacturing technology that allows construction and demolition recyclers and hot mix asphalt producers to pelletize asphalt shingle waste at the end of their original life to be reused in asphalt paving applications.

Originally developed by Asphaltica and acquired by CertainTeed in 2023, the RenuCore pelletizing technology allows CertainTeed to divert shingle materials from landfills and increases the recycled content in hot mix asphalt paving, all while maintaining equivalent performance. The launch comes as Saint-Gobain continues to execute its global "Grow and Impact" strategy, which includes sustainability goals, such as a commitment to achieve zero waste-to-landfill across all Saint-Gobain locations.

The innovative recycling process improves the performance grade of recycled asphalt and aims to achieve equivalent durability and longevity of roads compared to hot mix asphalt made with virgin materials. This new technology addresses early challenges in recycling asphalt shingles into hot mix asphalt by pre-treating and pelletizing the shingles, resulting in greater resistance to rutting, shoving, and cracking.

"RenuCore's launch underscores Saint-Gobain's commitment to the cross-industry collaboration that will be needed to Make the World a Better Home," said Carmen Bodden, president of CertainTeed Roofing Products Group. "Whether our products are on a roof or in asphalt paving, we remain committed to CertainTeed's motto ‘Quality made Certain, Satisfaction Guaranteed,' as we have done for the past 120 years."

RenuCore will officially launch at the Construction and Demolition Recycling Association's 10th Shingle Recycling Forum, the premier event for shingle recycling. The forum will take place in Louisville, Kentucky on Oct. 29-30, 2024 and feature remarks from members of the CertainTeed Roofing team.

This launch follows several other recent actions taken by the company to solidify its commitment to sustainability:

• In August, Saint-Gobain enhanced operational practices at its glass mat plant in Charleston, S.C., saving over 4,500 megawatt-hours of energy.
• In July, Saint-Gobain announced that it will save over 10 million gallons of water per year through the installation of smart water submetering systems and other equipment upgrades at its CertainTeed Siding facility in Jackson, Mich.
• In April, Saint-Gobain achieved Core Living Building Ready designation from the International Living Future Institute for its CertainTeed Innovation Center in Malvern, Pa.
• In March, Saint-Gobain announced that its CertainTeed Siding business had reduced manufacturing-related emissions by 96% at three facilities in the United States.
• In February, Saint-Gobain completed the installation of a heat recovery system at its gypsum facility in Vancouver, British Columbia, which will lead to a 15% reduction in Scope 1 carbon emissions.
• In September 2023, Saint-Gobain signed a 15-year, 100-megawatt power purchase agreement with TotalEnergies for the purchase of solar power, expected to offset Saint-Gobain North America's CO₂ emissions from electricity by 90,000 metric tons per year.
