Video Transcript (the English captions on the screen, revised)

Using a biogas digester. After fermenting for one month, biogas appears in the digester. We start using the biogas once the biogas bag is fully inflated. It is difficult to burn the biogas when the gas quantity is low. It is better to wait until the biogas bag is inflated once again. Biogas cooker use. For safety, please follw these instructions: open fan, open gas safety valve, light the burner, place pot on the burn, and turn up the biogas valve. Additional benefits. Contributes to cleaning the environment and provides gas for cooking. Biogas is also used as fuel for running other applications such as the generator, water heater...In addition, residues from biogas digesters can be used as fertilizer for agriculture.
