• Non-dilutive funding will cover $200,000 of the estimated $675,000 engineering cost related to Northstar's planned expanded-capacity asphalt shingle reprocessing scale up facility in Calgary, Alberta
• The application to Alberta Innovates was Northstar's first of a broad range of government funding applications Northstar is progressing related to the Calgary scale up facility

Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce that it has executed an investment agreement (the "Investment Agreement") dated March 3, 2022, with Alberta Innovates, a provincial Crown corporation and Alberta's largest research and innovation corporation. Alberta Innovates reviewed Northstar's application and approved a total of $200,000 in funding towards the estimated $675,000 of direct engineering costs. Northstar is required to use this funding to pay for a portion of the engineering costs for its planned expanded-capacity asphalt shingle reprocessing scale up facility in Calgary ("Calgary Empower Facility"), which was previously announced on March 17, 2022.

Dr. John Zhou, Vice President, Clean Resources of Alberta Innovates, stated, "Diverting waste from landfill reduces land disturbance and GHG emissions, while also providing products consumers need. Technologies enabling a circular economy, advanced materials, and energy innovation are creating jobs and enhancing sustainability in Alberta."

Mr. Aidan Mills, President & CEO and Director of Northstar stated, "As part of our engagement strategy at the federal, provincial, state, and municipal levels of government, we are progressing a wide range of non-dilutive funding applications. For Calgary, those applications cover engineering, procurement, construction, commissioning, and operational ramp up. We are therefore thrilled to receive the first award from this broad range of grant applications, providing support for our first activity: engineering design. This successful application reinforces our belief that our services and technology strongly appeal to governments. The award from Alberta Innovates recognizes the value of our proprietary clean technology that can not only divert between 30,000 to 50,000 tonnes of discarded asphalt shingle waste from Calgary landfills, but can place the end products of liquid asphalt, aggregate, and fiber back into the market. As governments increase their focus on zero waste, Northstar is positioned to lead the transition of asphalt shingles from depositing in landfills to repurposing in the circular economy. We expect this level of government support to continue covering costs with both the Calgary Empower Facility and future planned facilities. We will inform the market on subsequent awards in due course."

The $200,000 in funding was awarded under Alberta Innovates' Bioenergy Program. The transaction was approved by Alberta Innovates management. The investment will be paid in accordance with agreed milestones for the project.

Northstar and Alberta Innovates have both approved the Milestone Reporting and Payment Schedule ("MRP"). The completed MRP is used to define the project term and project costs in the Investment Agreement.

Northstar's Empower Pilot Facility in Delta, British Columbia, recently initiated steady-state production. The Company is now producing sustainable low carbon liquid asphalt through its proprietary Bitumen Extraction & Separation Technology ("BEST"). The Empower Pilot Facility reprocesses discarded single-use asphalt shingles into liquid asphalt, fiber, and aggregate, allowing these products to enter the circular economy while diverting waste from landfills. Our Calgary Empower Facility is expected to build on the Empower Pilot Facility through the engineering design study that Alberta Innovates has generously supported through its Bioenergy Program.

About Northstar

Northstar Clean Technologies Inc. is a Vancouver-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, aggregate and fiber for usage in new hot mix asphalt, 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 in the circular economy. 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.
