VANCOUVER, BC, April 20, 2023 - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce that it has filed its audited annual financial statements and management's discussion and analysis ("MD&A") on SEDAR for the year ended December 31, 2022. These documents are also available on the Company's website at www.northstarcleantech.com. The Company would like to remind its stakeholders that it has scheduled a virtual investor webcast to discuss these results and to provide a business update to the investment community today Thursday, April 20, 2023 at 2:00 pm PDT / 5:00 pm EDT. Details are provided below. Financial references are in Canadian dollars unless otherwise specified.

Mr. Aidan Mills, President & CEO and Director of Northstar, commented, "2022 was a strong year for Northstar, as we made significant steps to de-risk our proprietary front-end patented technology. The Company initiated production at its existing pilot facility in Delta, BC (the "Empower Pilot Facility"), which delivered significant results in several key areas:

• The production fully proved the Company's proprietary Bitumen Extraction & Separation Technology ("BEST") with shingle feedstock processed into aggregate, fiber and asphalt (the "Products").
• The process enabled the supply of Products to potential customers for detailed testing, research & development. This testing helped to secure the long-term off-take agreement for the Calgary facility (the "Empower Calgary Facility") with McAsphalt Industries ("McAsphalt"),and allowed subsequent successful testing with a number of shingle and flat roof manufacturers. Importantly, the testing results supported the Company's view that the asphalt produced by the BEST technology is suitable for all three target markets: (i) paving, (ii) shingle manufacturing and (iii) flat roof manufacturing.
• The production of Products generated valuable feedback for the design of the Empower Calgary Facility from customers, vendors and from the production process itself. The feedback has been incorporated into the detailed design process for the Empower Calgary Facility by the Company's vendors and as part of the integrated facility design led by BBA Engineering Ltd. In the Company's view, the feedback, derived from steady state operations at the Empower Pilot Facility, significantly de-risks the Empower Calgary Facility design."

"We built on this progress by achieving major milestones in Q4 2022 and Q1 2023, including the definitive off-take agreement with McAsphalt, the $7.1 million government grant award from Emissions Reduction Alberta, the issuance of our first patent from the United States Patent and Trademark Office ("USPTO"), letter of intent for our first US facility and Calgary site selection and permitting," continued Mr. Mills.

"We are continuing to focus our time, efforts and financial resources on our Empower Calgary Facility. We believe that our updated project economics and internal capital estimate demonstrate the compelling payback and return from this first-of-its-kind project. 2023 will be the most critical year in the Company's history, as we focus on building, constructing and financing the Empower Calgary Facility. We are currently in advanced negotiations on a non-dilutive funding structure to supplement the ERA government grant award and expect to provide an update to the market in Q2 2023," concluded Mr. Mills.

About Northstar

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.
