Northstar Clean adds limestone as fourth product line

Mr. Aidan Mills reports NORTHSTAR ANNOUNCES LIMESTONE AS FOURTH PRODUCT LINE, SUPPORTED BY NEW PATENT ON RECOVERY PROCESS Northstar Clean Technologies Inc. has successfully separated and recovered limestone from asphalt shingles, adding a fourth product line for the company. Northstar has also been issued a new patent by the U.S. Patent and Trademark Office (USPTO) for this limestone recovery portion of the company's proprietary asphalt shingle reprocessing technology. The patent is expected to remain in force until 2045. Limestone is added to improve durability and longevity of shingles. The limestone, which is removed in Northstar's proprietary process to deliver its superior quality asphalt, now establishes a fourth product line for the company, adding to the existing product lines of liquid or pelletized asphalt, aggregate and fibre/fibreglass. "By extracting limestone directly from asphalt shingles, we've been able to establish both a fourth product line for the company and, most importantly, to deliver a final asphalt product with high-quality characteristics," commented Aidan Mills, president and chief executive officer of Northstar. "Additionally, this patent adds further protection to Northstar's intellectual property portfolio while strengthening our first-mover advantage. We believe the high quality of our asphalt will continue to provide significant differentiation for Northstar in the global marketplace." Northstar received its initial U.S. patent in November, 2022, and has successfully obtained patents in the United States and Canada. The company continues to pursue further patent protection for its proprietary asphalt shingle reprocessing technology in the United States, Canada and other international jurisdictions.
