NORTHSTAR AWARDED NEW PATENT FOR PROPRIETARY ASPHALT SHINGLE REPROCESSING TECHNOLOGY

Northstar Clean Technologies Inc. has been issued a new patent by the U.S. Patent and Trademark Office for the company's proprietary asphalt shingle reprocessing technology. The patent is the fourth related to Northstar's proprietary process to deliver its superior-quality asphalt with focus on recovering aggregate.

"This patent reflects Northstar's continued commitment to advancing asphalt shingle reprocessing and strengthening the intellectual property underlying our proprietary process," said Aidan Mills, Northstar president and chief executive officer. "With a particular focus on aggregate recovery, this patent represents our fourth issued patent and the third associated with our core reprocessing process in the United States. It further strengthens the protection around our technology as we work to divert valuable materials from landfill and recover them as high-quality products that can provide alternative sources of materials for our customers and support their own sustainability objectives."

Northstar received its initial U.S. patent in November, 2022, and has successfully obtained multiple patents in the United States and Canada since then. The company continues to pursue patent protection for its proprietary asphalt shingle reprocessing technology in the United States, Canada and other international jurisdictions.
