Greenlane Reveals Cascade LF, Its Next-Generation Landfill Gas Upgrading System

Executive Summary

• Greenlane Renewables Inc. unveiled "Cascade LF," a next-generation landfill gas upgrading system designed to maximize methane recovery while minimizing capital investment.
• The new system integrates patent-pending advancements with proven technology to address industry challenges regarding the high cost and performance limitations of current landfill gas upgrading solutions.
• Cascade LF aims to make Renewable Natural Gas (RNG) projects more accessible and scalable by reducing upfront costs and enhancing revenue-generating output for project owners.

Key Details

• Product Name: Cascade LF (Next-generation landfill gas upgrading system).
• Key Value Proposition: Delivers maximum methane recovery at minimized capital investment; addresses the industry challenge of achieving low cost and high performance simultaneously.
• Technology Components:
  • Membrane Separation: Features permeate sweep technology for near-complete carbon dioxide removal at very high methane recovery. The separated CO2 stream can be sequestered for ultra-low carbon intensity or used for value-add purposes.
  • Catalytic Deoxygenation: A proprietary, patent-pending integrated process that eliminates oxygen using a simple design and avoids the need for a dedicated dryer. Cost is further reduced at lower oxygen levels where catalytic deoxygenation is not required.
  • Equilibrium Pressure Swing Adsorption (PSA) Nitrogen Rejection Unit: Utilizes a proprietary module to remove only the necessary amount of nitrogen to meet final biomethane/RNG product gas specifications, ensuring high methane recovery after CO2 and oxygen removal.
• Company Background: Greenlane has over 35 years of industry experience, having supplied more than 355 systems into 28 countries.
• Support: Operational reliability is backed by 24/7/365 expert technical support.
• Launch Context: Announced at the RNG WORKS 2025 Technical Workshop and Trade Expo in Nashville, Tennessee.

Notable Quotes

• "Today's industry state-of-the-art landfill gas upgrading technology is too costly for the performance it delivers," said Brad Douville, CEO of Greenlane. "The challenge is achieving both low cost and high performance when oxygen and nitrogen need to be removed."
• "Our goal is to make RNG projects more accessible and scalable by enabling project owners to enhance revenue generating RNG output from their assets while minimizing upfront investment."
