Northstar Announces Completion of Milestones Required to Commence Detailed Engineering

VANCOUVER, BC, May 30, 2023 /PRNewswire/ - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce the completion of certain milestones required to commence detailed engineering for its planned asphalt shingle reprocessing scale-up facility in Calgary, Alberta (the "Empower Calgary Facility").

Mr. Aidan Mills, President & CEO and Director of Northstar, stated, "We are now set to move into detailed engineering for the Empower Calgary Facility. The production de-risking completed at our pilot facility in Delta, British Columbia (the "Empower Pilot Facility") has allowed us to identify opportunities for increased efficiencies, implement them and test in parallel; to complete vendor testing and verify production specification for asphalt; and to support McAsphalt in its blending and mixing studies to ensure our products can effectively enter McAsphalt's product portfolio."

McAsphalt Industries Inc. ("McAsphalt"), the Company's liquid asphalt off-take partner for the Empower Calgary Facility, continues to work with the Company to fully incorporate their expertise in storage, blending and load out facilities into the overall Facility detailed engineering.

The Company also identified opportunities for increased efficiencies during the operation of the Empower Pilot Facility in 2022. Using the leading R&D company Coanda, a subsidiary of Tectra Tech, a high-end global consulting and engineering firm, the Company has now completed the redesign to address the inefficiencies identified. The Company will now incorporate this redesign into the detailed engineering for the Empower Calgary Facility. In parallel, the Company will construct process equipment at the Empower Pilot Facility to determine the optimal operating parameters for the redesigned facilities. In line with the production de-risking already carried out at Delta, this will enable full operating conditions to be determined ahead of the commencement of operation at the Empower Calgary Facility.

Major equipment vendor design tests have also been successfully completed, with equipment now ready to complete the detailed design phase. This included final design testing of a major piece of equipment, with the test results verified by a number of major domestic and international asphalt shingle and flat roofing manufacturers previously mentioned in the Company's press release dated March 8, 2023.

About Northstar

Northstar Clean Technologies Inc. is a Canadian-based clean technology company focused on the sustainable recovery and reprocessing of asphalt shingles.
