VANCOUVER, BC, Feb. 14, 2023 /CNW/ - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce that it has received a Notice of Advanced Examination (the "Notice") from the Canadian Patent Office ("CPO") dated February 1, 2023. The Notice confirms approval by CPO of Northstar's request for advance examination of its patent application for the Company's innovative technology for reprocessing asphalt shingles 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.

Mr. Aidan Mills, President & CEO and Director of Northstar, stated, "We are progressing quickly with the development of our intellectual property portfolio. Following the issuance of our first patent by the US Patent & Trademark Office in November 2022, we are excited to receive this news from the Canadian Patent Office. It is incredibly gratifying for our team to know that the Canadian Patent Office agrees that our patent application relates to green technology and we can therefore take advantage of the CPO fast-track process. We anticipate receiving an expedited ruling on our patent application and look forward to the next steps in the application process."

Northstar Clean Technologies Inc. is a Canadian-based clean technology company focused on the sustainable recovery and reprocessing of asphalt shingles. Northstar has developed a proprietary design process for taking discarded asphalt shingles, otherwise destined for already over-crowded landfills, and extracting the liquid asphalt for use in new hot mix asphalt, shingle manufacturing and asphalt flat roof systems, and aggregate and fiber for use in construction products and other industrial applications. Focused on the circular economy, Northstar plans to reprocess used or defective asphalt shingle waste back into its three primary components for reuse/resale at both its Empower Pilot Facility in Delta, British Columbia and its first commercial scale up facility in Calgary, Alberta. As an emerging innovator in sustainable processing, Northstar's mission is to be the leader in the recovery and reprocessing of asphalt shingles in North America, extracting the recovered components from asphalt shingles that would otherwise be sent to landfill.
