Not all landfill gas (LFG) upgrading projects are created equal. The best biogas upgrading technology for one landfill may not be the best choice for another. As the only provider of all three landfill gas upgrading technologies (water wash, Pressure Swing Adsorption [PSA] and membranes), Greenlane Biogas has a unique perspective and an unbiased approach to technology selection. In this presentation, we will look at two different sites where LFG is being upgrading to pipeline quality using two different technologies, and compare and contrast the applications and the treatment systems used.
