Northstar produces asphalt from tear-off shingles

Executive Summary

• Northstar Clean Technologies successfully produced its first liquid asphalt from end-of-life, tear-off shingles and converted it into solid pellets at its Calgary facility.
• This achievement validates the company's proprietary technology, confirming it can recover high-quality liquid asphalt from both manufacturing waste shingles (previously achieved) and tear-off shingles.
• The production of solid pellets addresses logistical challenges, potentially enabling global market access by transforming the product into a transportable global commodity.

Key Details

• Process Milestone: Successfully produced liquid asphalt from end-of-life, tear-off shingles and converted the recovered liquid asphalt into solid pellets.
• Feedstock Validation: Confirmed that proprietary technology can recover high-quality liquid asphalt from two distinct feedstock types:
  1. Manufacturing waste shingles (previously announced milestone on July 10, 2025).
  2. Tear-off shingles (discarded shingles from roof removal/replacement).
• Product Specifications: Independent third-party lab results confirmed high-quality specifications for the asphalt produced from both manufacturing waste and tear-off shingles.
• Market Implication: The ability to pelletize liquid asphalt from tear-offs creates substantial market access opportunities through optimized logistics, effectively establishing the product as a global commodity.
• Facility Location: Calgary, Alberta.

Notable Quotes

• "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."
