08:59 AM EDT, 10/20/2025 (MT Newswires) -- Greenlane Renewables ( GRNWF ) said Monday it has filed a new patent application for a Linear Nitrogen Rejection Unit (NRU) as part of its Cascade LF product line, the company's newest landfill gas upgrading technology.

According to a statement, the Linear NRU allows the Cascade LF to achieve even higher methane recovery performance at a lower cost.

"This patent filing marks another important milestone in our commitment to customer-focused innovation and relentless pursuit of improving the state-of-the-art of technology in our industry," said chief executive Brad Douville. "We took direct input from our customers to make a great product even better -- pushing the boundaries of methane recovery while driving costs down further."

Douville said the company is now quoting its Cascade LF products incorporating the Linear NRU, with first system delivery targeted before the end of 2026. "Our Linear NRU may also have applications beyond biogas, broadening the potential reach of our technology, reinforcing Greenlane's leadership in advancing real-world technologies that accelerate decarbonization."
