VANCOUVER, BC, Feb. 24, 2023 /PRNewswire/ - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce that its wholly owned subsidiary Empower Environmental Solutions Calgary Ltd. has signed a long-term 15-year lease agreement (the "Lease") with the Mook Group of Companies (the "Landlord") for an industrial-zoned property of 3.98 acres located in Rocky View County, a municipal district adjacent to the City of Calgary, Alberta, as the site for the Company's planned scale-up facility in Calgary (the "Empower Calgary Facility").

The Lease is for an initial term of 15 years, with two extension options of five years each. The 125m x 125m site is strategically located just outside of metropolitan Calgary, easily accessed 4.4km southeast of the City of Calgary East Landfill. The Company can access the site starting July 1, 2023. The Lease also allows for certain improvements to be made and financed under the lease at Northstar's discretion.

Mr. Aidan Mills, President & CEO and Director of Northstar, stated, "We are excited to have secured a suitable long-term site location for our Empower Calgary Facility, conveniently located near the existing City of Calgary East Landfill. This location gives us not only the space we need for the Empower Calgary Facility, but also makes disposal of single use asphalt shingles and pick up of our end products convenient for our customers and partners. This site provides us with a great location to construct the Company's first scale up facility and enables us to deliver the shingle diversion, reprocessing and circular economy solution we have promised. This flagship facility will provide the foundation for Northstar's expansion across Canada and the US as we roll out our innovative technology."

Mr. Jon C. Mook, Founder and President of the Mook Group of Companies, stated, "After much hard work, we are happy to announce that Northstar Clean Technologies is a tenant in our portfolio and we will be a partner in Northstar's new facility in Rocky View County. Northstar's requirements are familiar to us as we have similar tenants in our portfolio today and we believe we can add value working with them to create a start-of-art processing facility in Alberta that is focused on clean technology."

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.
