Municipal solid waste (MSW) landfills are one of the largest human-generated sources of methane emissions in the United States and other countries globally. Methane is believed to be a very potent greenhouse gas that is a key contributor to global climate change, over 21 times stronger than CO2. Methane also has a short (10-year) atmospheric life. Because methane is both potent and short-lived, reducing methane emissions from MSW landfills is one of the best ways to achieve a near-term beneficial impact in mitigating global climate change. The United States Environmental Protection Agency estimates that a landfill gas (LFG) project will capture roughly 60-90% of the methane emitted from the landfill, depending on system design and effectiveness. The captured methane can be then purified and used for industrial applications, as in this case the production of SCP. Utilizing methane in this way decreases its demand from fossil fuels which is its traditional source.
