It is primarily a mix of CH4 and CO2. Biogas is produced from the anaerobic fermentation of carbohydrates in plant material or waste (eg food peelings or manure) by bacteria and thus is renewable. While combustion of biogas, like natural gas, produces carbon dioxide (CO2), a greenhouse gas, the carbon in biogas comes from plant matter that fixed this carbon from atmospheric CO2. Thus, biogas production is carbon-neutral and does not add to greenhouse gas emissions. It has an energy content of 889 kJ mol-1. Biogas can be used for any heating purpose, such as cooking. It can also be used in a gas engine to convert the energy in the gas into electricity and heat.

Advantages:
renewable
Carbon-neutral 
Reduces landfill

Disadvantages:
unstable 
Not economically viable on a large scale
Contains impurities

What other uses are there for biofuel that haven't been discovered?
Is there a way to refine biofuel further so that there are no impurities?]]> 2017-02-01 23:11:16 UTC https://padlet.com/cinnamonlane1/bicsbwdr2zal/wish/151011789 https://padlet.com/cinnamonlane1/bicsbwdr2zal/wish/151066747 It is a biofuel and is produced by organic matter (such as plant matter) through the process of anaerobic respiration (fermentation). It is carbon neutral and is renewable

Advantages:
Carbon neutral
Renewable
Non polluting
The nitrogen released acts as a natural fertiliser in the soil.
It reduces landfill.
Decreased soil and water pollution .
Large number of jobs.
Not very expensive.
Reduces greenhouse effect.

Disadvantages:
Biofuel is unstable 
Inefficient when produced on a large scale
Lots of organic matter required.
Contains impurities that could affect car engines.
Large investment required.

Applications:
Could be used to generate thermal and electrical energy for the public grid or individual households.
