Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas (LFG) over time. Abou

t 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 period. LFG can be collected and burned to produce electricity.
a. Explain a process during which LFG is burned to produce electricity.
b. The Puente Hills Landfill in California contains about 123 million tons of landfill waste and burns LFG to produce electricity. In a typical landfill, one million tons of landfill waste emits approximately 432,000 cubic feet of LFG per day. Calculate how much LFG is emitted at the Puente Hills Landfill per year.

The amount of LFG produced in a year from the calculations is 1.5768 * 10^8 cubic feet.

<h3>What is LFG? </h3>

The acronym LFG stands for land fill gas. It is a gas that is produced by the decomposition of biomass in a land fill. This gas can be burnt to generate steam. This steam is used to turn a turbine and generate electricity.

If 1 million tons of LFG is burnt in  a day, then 365 million tons of LFG is burnt in one year.

1 million tons of waste produces  432,000 cubic feet of LFG

365 million tons of waste produces 365 million tons * 432,000 cubic feet /1 million tons

= 1.5768 * 10^8 cubic feet of LFG

1. In a hot-spot volcanic island chain, such as the Hawaiian Islands, all islands possess active volcanoes simultaneously and th
AleksandrR [38]

Answer:

<u>True</u>.

Explanation:

  • As the volcanic islands of Hawaii are still considered to be in an active zone, as the Hawaiian islands are believed to be formed on the hotspot of eruptions ie. the active plate boundaries from below the surface these tend to move westwards direction from the main island of Hawaii.
  • As we go from east to west the chain of rocks gets older and then forms a ring-shaped pattern hence called the ring of fire. Thus there is a great risk of volcanic hazard as these are fault lines being associated with high magnitude tectonic earthquakes.
  • They can have a seriously damaging impact upon other islands as well and this considered to be highly hazardous. As various vents and mounds of volcanic nature lie within the oceans of the Pacific plate.
