• many sources of biogas
  • natural occurring process - requires less land
  • using biogas - reduces greenhouse gas emissions


  • since natural occurring process - can't control/manipulate
  • gas production slowed down in cool weather
  • using manure/other waste - can't be used for fertilizer and compost
  • produces limited quantity of energy

What qualifies it as a biofuel? How does it work?

  • qualified as biofuel - creates energy
  • produces when microorganisms digest waste from plants/animals in the absence of oxygen

Interesting Info

  • methane is 21 times stronger as greenhouse gas than carbon dioxide

Good idea to move into production?

  • should probably use during warm seasons due to slow gas production in cool seasons
  • should probably use to help out with something else
