VANCOUVER, BC and CALGARY AB, July 15, 2024 - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce that it has been issued a patent (the "Patent") for the Company's front-end technology for reprocessing asphalt shingles from the Canadian Intellectual Property Office (the "CIPO"). The Patent is expected to remain in force until 2042. Further, Northstar has a pending Patent Cooperation Treaty ("PCT") application which preserves the right to file a patent application in any of the 157 PCT contracting states.

Mr. Aidan Mills, President & CEO and Director of Northstar, stated "We are pleased to have received our fast-tracked Canadian Patent for our proprietary asphalt shingle reprocessing technology. The Patent follows two patents issued by the United States Patent and Trademark Office ("USPTO") for both the front-end technology for reprocessing asphalt shingles and the follow-on patent for the second stage of our four-stage proprietary technology for reprocessing asphalt roofing shingles. We continue to advance further patents with the CIPO, USPTO and international patent offices, as we seek to protect the strength of our proprietary technology in Canada, the United States and abroad."

The Patent application was previously granted fast track status, as announced by the Company on February 14, 2023, on the grounds that the application relates to green technology that either helps resolve or mitigate environmental impacts or conserves the natural environment or natural resources.
