Northstar produces asphalt from tear-off shingles

Mr. Aidan Mills reports NORTHSTAR ENABLES GLOBAL MARKET ACCESS FOR REPROCESSED LIQUID ASPHALT THROUGH SUCCESSFUL PELLETIZATION OF END-OF-LIFE, TEAR-OFF SHINGLES Northstar Clean Technologies Inc.'s asphalt shingle reprocessing facility in Calgary, Alta., successfully produced its first liquid asphalt from end-of-life, tear-off shingles and subsequently converted the recovered liquid asphalt into solid pellets. The facility has now produced high-quality solid asphalt pellets, providing the potential for significant market access through optimized logistic options. Tear-off asphalt shingles are the discarded shingles collected when existing roofs are removed or replaced. These end-of-life shingles are typically directed to landfills for final disposal. This follows the company's previously announced milestone of producing liquid asphalt from manufacturing waste shingles on July 10, 2025. Manufactured waste shingles comprise those that for various design specifications or quality are not sold for commercial use and similar to tear-off shingles, are typically discarded into landfills. With both manufacturing waste and tear-off shingles now successfully processed, Northstar has confirmed that its proprietary technology can recover high-quality liquid asphalt from both types of feedstock. "Tear-off shingles represent the largest portion of the shingle waste stream, and successfully producing liquid asphalt from this material is an important step for not only the Calgary facility but more importantly, validates the robustness of the technical process," said Aidan Mills, Northstar's president and chief executive officer. "This confirms the ability to produce high-specification asphalt from both manufacturing waste and tear-off shingles and, critically, confirms the process successfully pelletizes the liquid asphalt from tear-offs. Northstar's pelletized product creates substantial market access opportunities through the transport of a solid form product, effectively establishing it as a global commodity. "In addition, we received the results from independent third party labs confirming high-quality specifications for the asphalt produced from both manufacturing waste and tear-off shingles. These results, combined with the facility's ability to process both types of feedstock delivers on the primary objective of the business -- to reprocess waste shingles into high-quality products to provide a compelling value proposition for customers and shareholders alike." Investor conference call reminder Northstar will host a virtual investor webcast on Wednesday, Sept. 10, 2025, at 2:30 p.m. MT/4:30 p.m. ET to review Q2 2025 financial results and provide an operational update. About Northstar Clean Technologies Inc. Northstar is a Canadian waste to value technology company focused on the sustainable recovery and reprocessing of asphalt shingles. Northstar developed and owns a proprietary design process for taking discarded asphalt shingles, otherwise destined for already overcrowded landfills and extracts the liquid asphalt for use in new hot mix asphalt shingle manufacturing and asphalt flat roof systems while also extracting aggregate and fibre 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 with its first commercial scale-up facility in Calgary, Alta. As an emerging innovator in sustainable processing, Northstar's mission aims at leading the recovery and reprocessing of asphalt shingles in North America that would otherwise be sent to landfill addressing numerous stakeholder objectives.
