Landfills represent significant sources of biogas in the USA, with over 2,500 sites in the country, and only about 20% of these landfills currently have operational waste-to-energy facilities. Most of the existing landfill gas-to-energy facilities consist of electricity generation, while the few Renewable Natural Gas (RNG) facilities are typically constructed on larger landfills with substantial gas flow capacity. However, recent trends over the past three years have shown an undeniable shift in preference towards RNG projects in landfills. Small and midsize landfills have often been overlooked for RNG projects due to their limited gas flow and the significant investment required. The WAGABOX ® technology unlocks the full RNG potential of landfill gas, especially for small-to-medium sized landfills. The WAGABOX® technology upgrades landfill gas into renewable natural gas in a revolutionary way: by pairing cryogenic distillation and membrane filtration. What sets the WAGABOX® technology apart is its ability to unlock the full RNG potential of landfill gas. The deployment of a WAGABOX® unit minimally impacts landfill operations, contributes to improved air quality, and boasts a modular, scalable design. This presentation outlines the advantages of WAGABOX® technology and the role of renewable natural gas in transforming landfills into sustainable energy sources.
