08:28 AM EDT, 04/07/2025 (MT Newswires) -- Northstar Clean Technologies ( ROOOF ) on Monday said it has been issued a Canadian follow-on patent for its asphalt shingle reprocessing technology. The patent relates to Stage 3 of the reprocessing technology, the asphalt recovery stage, and is expected to remain in force until 2042.

"As a clear first mover in this emerging industry, securing further patents for Northstar's reprocessing technology is a critical step in securing, reinforcing and sustaining our technological advantage," said Aidan Mills, chief executive officer. "The latest patent protects a key part of our recovery process at the heart of our business, just as we prepare to commence commercial production in mid-2025 at our Calgary facility, a significant milestone for the company."

Northstar received its initial Canadian patent last July.
