Northstar Clean Technologies recently announced a new product line.
The Calgary-based company is focused on waste-to-value technology, specifically the sustainable recovery and reprocessing of asphalt shingles as part of a circular economy.
The new product from Northstar involves separating and recovering limestone from shingles.
“By extracting limestone directly from asphalt shingles, we’ve been able to establish both a fourth product line for the Company and … deliver a final asphalt product with high-quality characteristics,” stated Aidan Mills, chief executive officer of Northstar.
Limestone, added to improve durability and longevity of shingles, is removed via Northstar’s proprietary process. This process, which has been patented in the U.S. until 2045, arrives in addition to the existing product lines of liquid or pelletized asphalt, aggregate, and fibreglass.
“This patent adds further protection to Northstar’s intellectual property portfolio while strengthening our first-mover advantage,” the CEO stated, adding that “We believe the high quality of our asphalt will continue to provide significant differentiation for Northstar in the global marketplace.”
Focused on the circular economy, Northstar plans to reprocess used or defective asphalt shingle waste back into primary components for resale through its first commercial scale-up facility in Calgary.
Northstar unveiled the Empower Calgary Facility, whose launch was supported by the Business Development Bank of Canada, and followed a pilot run in Delta in 2021, earlier this year.
The Alberta innovator trades on the TSX Venture Exchange under the ticker ROOF.
