The purpose of this data-file is to model the typical costs of producing raw landfill gas (a mixture of CH4, CO2 and other impurities) at a solid waste landfilling facility.
Our capex and opex cost build-ups are derived from EPA guidance and our gas evolution equations are derived from a line-by-line breakdown of landfill products (below). Note this is prior to gas cleaning and upgrading.
We estimate that a typical landfill facility may be able to capture and abate 70% of its methane leaks for a CO2-equivalent cost of $5/ton. Other landfill gas pathways get more complex and expensive.
