To use the biogas system, a fanner must move animal waste into a pipe with water. These pipes bring the waste to a tank (7)……..in the ground. This tank is called a bio-digester. Air cannot enter this tank. In this contained environment, natural bacteria decays the waste material. (8)……..the waste decays in the bio-digester, it (9)…….two things - biogas and slurry. The biogas rises to the top of the tank. The pressure from the gas pushes the liquid slurry into (10)……. Now people can use both the biogas and the slurry.
