Multinational manufacturer Saint-Gobain North America has obtained the rights to proprietary asphalt recycling technology from Asphaltica.

The move advances Saint-Gobain's Grow and Impact sustainability strategy. The French-owned company, through its subsidiary CertainTeed Roofing, will now have the ability to pelletize both post-industrial and post-consumer shingle waste.

“By taking an innovative approach and embracing new technologies, Saint-Gobain and CertainTeed Roofing are making strides to maximize our positive impact while minimizing our environmental footprint,” said Carmen Bodden, vice president of CertainTeed Roofing. “CertainTeed takes our sustainability commitments seriously. The Asphaltica technology is proven and will help us achieve our goal of keeping shingle manufacturing waste across our network out of landfills.”

The recycling method produces pellets from ground shingles, which are then integrated into hot-mix asphalt. The company added that the pellets are "highly water resistant and can be used in variable climate conditions."

Saint-Gobain noted the tech as part of its larger goals to reduce waste and to increase the circularity of raw materials in its production processes for construction and industrial markets. The company recently launched a circular program for automotive windshield glass in California. Glass at Saint-Gobain's Garden Grove facility is transferred to CertainTeed to be processed into fiberglass insulation.

“Replacing virgin asphalt in asphalt paving with properly treated recycled asphalt products is both economical and sustainable,” said Bill Dempsey, Asphaltica president. “By using the pelletizing process of asphalt shingles at the end of life, our companies will provide recycled, environmentally friendly, paving grade materials for paving projects large and small.”

Both Dempsey and Asphaltica CEO Bill Bailey will continue to assist with landfill diversion efforts in roles with CertainTeed.

“It was important to me personally to partner with an organization that has the global vision and resources to do big things, and that is why I am so proud to partner with Saint-Gobain and CertainTeed,” said Bill Bailey, Asphaltica CEO. “Their commitment to sustainability is unmatched and I look forward to working with their roofing team as they continue their work to be leaders in light and sustainable construction.”
