Through its building products subsidiary CertainTeed Roofing, Malvern-based Saint-Gobain North America has acquired the rights to technology from Asphaltica, its recycling partner, that will allow it to recycle asphalt shingle waste, writes Emily Atkins for the Waste & Recycling. 

The proprietary technology will make it possible for Saint-Gobain to pelletize post-industrial as well as post-consumer shingle waste. The process makes pellets out of ground shingles which blend well in hot mix asphalt. The pellets are also highly water resistant, which makes them usable in variable climate conditions. 

This technology will help Saint-Gobain contribute to the goals set by the Asphalt Roofing Manufacturing Association to bring landfill disposal of asphalt-based roofing materials down to 50 percent by 2035. 

Meanwhile, Saint-Gobain has also set a goal to have a net zero carbon footprint by 2050 through the reduction of waste and an increase in the circularity of raw materials in its production processes. 

“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 Malvern-based CertainTeed Roofing.
