Greenlane Advances Its Next-Generation Landfill Gas Upgrading Platform with New Patent Filing for Innovative Linear Nitrogen Rejection Technology

Executive Summary

• Greenlane Renewables filed a new patent application for a Linear Nitrogen Rejection Unit (NRU) that will be incorporated into its Cascade LF landfill‑gas upgrading platform.
• The Linear NRU is designed to boost methane recovery performance while lowering capital and operating costs, enhancing the competitiveness of RNG projects.
• The company is now quoting Cascade LF systems with the Linear NRU and targets delivery of the first such system before the end of 2026.

Key Details

• Patent filing: New application covering a Linear Nitrogen Rejection Unit (NRU) for the Cascade LF product line.
• Technology description: Uses equilibrium pressure‑swing adsorption (PSA) with a step‑wise gas enrichment process, eliminating internal gas recycling and requiring fewer/smaller adsorption beds.
• Performance impact: Expected higher methane recovery rates and reduced capital & operating expenditures versus conventional PSA NRUs.
• Commercial rollout: Cascade LF products incorporating the Linear NRU are now being quoted to customers; first system delivery anticipated before Dec 2026.
• Strategic benefit: Improves RNG project economics, making projects more accessible and scalable; potential applicability beyond biogas upgrading.
• CEO comment (Brad Douville): Emphasized customer‑driven innovation, the goal of maximizing waste‑resource value, and the broader decarbonization impact of the technology.
