Human and other animal waste can result in water and air pollution. Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas (LFG) over time. About 50% of LFG is methane, a greenhouse gas with a global warming potential 25 times higher than that of carbon dioxide over a 100-year time period. LFG can be collected and burned to generate electricity. a) The Puente Hills Landfill in California contains about 137 million tons of landfill waste and burns LFG to generate electricity. In a typical landfill, one million tons of landfill waste emits approximately 413,000 cubic feet of LFG per day. Calculate how much LFG (in cubic feet) is emitted at the Puente Hills Landfill per year. b) Burning LFG for electricity produces the additional benefit of preventing methane from entering the atmosphere. So, the methane is collected and burned to generate electricity. Calculate how much methane in cubic feet is prevented from entering the atmosphere by burning LFG to produce electricity at the Puente Hills Landfill over a 10-year period.
