    Typically, gas extraction rates from a municipal solid waste (MSW) landfill range from 25 to 10000 m 3 /h where Landfill sites typically range from 100,000 m 3 to 10 million m 3 of waste in place. [5] MSW landfill gas typically has roughly 45 to 60% methane and 40 to 60% carbon dioxide, depending on the amount of air introduced to the site ...
