Landfills are the third-largest source of human-related methane emissions in the United States, according to the U.S. Environmental Protection Agency (EPA). Globally, waste sectors account for nearly 20% of anthropogenic methane emissions. metf ch4

When organic waste — food scraps, yard trimmings, paper, and wood — decomposes anaerobically (without oxygen) in a landfill, it produces biogas, which is typically composed of: Date: October 2023 Subject: Scientific Consensus on Methane

Without intervention, this methane escapes into the atmosphere, accelerating climate change. Controlling METF CH4 is thus a non-negotiable part of national and corporate climate action plans. Landfill gas contains oxygen and nitrogen, which are

Landfill gas contains oxygen and nitrogen, which are challenging for membranes. However, specialized METF CH4 modules have been developed with high CH₄/CO₂ selectivity (e.g., 15:1) that can handle up to 3% O₂. This allows landfill operators to convert flared gas into pipeline-grade RNG, generating Renewable Identification Numbers (RINs) or carbon credits.
