Explain the relationship between monoculture and chemical<br>fertilizers. ​
faltersainse [42]

Answer:

(You can see the connection)

Explanation:

Monoculture is reusing the exact same soil, instead of rotating three or four different crops and chemical fertilizers make the soil so that the soil does not need to be replaced by adding the chemicals.

Organic materials (such as food scraps and yard waste) in landfills can decompose and produce landfill gas ( LFG ) over time. Ab
liubo4ka [24]

Based on the data provided:

  • LFG is used to produce electricity by using it as fuel in combustion turbines
  • the Puente Hills Landfill will emit 1.94 * 10¹⁰ cubic feet of LFG per year
  • 9.7 * 10¹⁰ cubic feet of methane is prevented from entering the atmosphere.
  • the number of households that can have their total electricity needs provided by these landfills is 1,368,925 households.

<h3>What is the process of electricity generation from LFG?</h3>

Landfill gas, LFG can be used to generate electricity.

It contains 50% methane which is used as fuel for energy generation.

The process of generating electricity from LFG is as follows:

  • It is processed to produce methane.
  • The methane produced is combined with natural gas
  • The mixture is used as fuel for combustion turbines which then drives energy generation.

<h3>How much LFG is emitted at the Puente Hills Landfill per year?</h3>

From the data given:

ii) 1 million tons of landfill emits  432,000 cubic feet of LFG per day

123 million tons of landfill waste will emit 123000000 * 432000/1000000 cubic feet of LFG per day

The Puente Hills Landfill will emit 53136000 cubic feet of LFG per day

1 year = 365.25 days

Amount of LFG emitted in 1 year = 53136000 * 365.25 cubic feet of LFG per day

Amount of LFG emitted in 1 year = 1.94 * 10¹⁰ cubic feet of LFG per year

Therefore, the Puente Hills Landfill will emit 1.94 * 10¹⁰ cubic feet of LFG per year

<h3>What is the amount of methane prevented from entering the atmosphere by burning LFG to produce electricity at the Puente Hills Landfill over a 10-year period?</h3>

Volume of LFG produced in Puente Hills Landfill in 10 years is calculated below:

1.94 * 10¹⁰ cubic feet of LFG per year * 10 years = 1.94 * 10¹¹ cubic feet of LFG

Volume of methane in 1.94 * 10¹¹ cubic feet of LFG = 1.94 * 10¹¹ * 50% Volume of methane in 1.94 * 10¹¹ cubic feet of LFG = 9.7 * 10¹⁰ cubic feet of LFG

Therefore, 9.7 * 10¹⁰ cubic feet of methane is prevented from entering the atmosphere.

<h3>How many households can have their total electricity needs provided by these landfills in the United States?</h3>

Average yearly household electricity need = 30 kWh * 365.25 days

Average yearly household electricity need = 10957.5 kWh per year

Number of households = total electricity from LFG / average household electricity use per year

Number of households = 15000000000/10957.5

Number of households = 1,368,925 households

Therefore, the number of households that can have their total electricity needs provided by these landfills is 1,368,925 households.
