Northstar Clean Technologies has been issued a patent by the United States Patent and Trademark Office (USPTO) for its front-end technology for reprocessing asphalt shingles.

Northstar’s proprietary technology reprocesses discarded asphalt shingles, otherwise destined for landfills, and extracts the liquid asphalt, fiber, and aggregate materials for use in paving asphalt, shingle manufacturing, asphalt flat roof systems, and other industrial applications.

“We are delighted to be issued our first patent from the USPTO for the front-end of our proprietary technology for reprocessing asphalt roofing shingles,” said Aidan Mills, President & CEO and Director of Northstar.

“The approval of this patent,” he added, “is a testament to the strength of our proprietary technology and helps protect the company’s intellectual property.”

While this patent is for the front-end process for Northstar’s proprietary technology, the company has also filed follow-on continuation patent applications with the USPTO, as well as an application for patent approval in Canada, and plans to file a Patent Cooperation Treaty international application.

The company expects this current patent to remain in force until at least 2042.

Northstar Clean Technologies Inc. is a Vancouver-based clean technology company focused on the sustainable recovery and reprocessing of asphalt shingles.
