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
