Aidan Mills, President and CEO of Northstar, stated that the patent bolsters the company’s ability to extract high-quality materials from discarded shingles. By isolating liquid asphalt, aggregate, limestone, and fiber, the firm aims to provide sustainable alternatives for construction and manufacturing sectors. This latest development follows an initial U.S. patent granted in November 2022 and underscores a broader strategy to secure intellectual property across North America and international markets. The company currently operates with a focus on a circular economy model, targeting the conversion of shingle waste into raw materials for new roofing and industrial applications.
