This video shows how to build a homemade anaerobic digester for making biogas. Made of of 55 gallon drum, valves, and PVC sewer pipe.Made for 75 dollars. Constructed of PVC and valves. Makes great fertilizer and methane gas can be captured for use in small engines, heaters, and lamps.

  • Hello, What kind of bacteria do you use to break down the waste? And how do you get hold of it in small quantities?

  • @EllenJWard

    The bacteria are anaerobic or found in the lack of oxygen. These types of bacteria are found in animal wastes. You can also get small quantities in a powdered form by buying septic tank treatment powder which contains the same bacteria.

  • is there any welding involved? i'm thinking of building one but i can't use a welding gun to save my life.....

  • @muzicalman

    No welding,only plumbing.

  • Very nice! Please put more videos so we can see how you use or store the gas and the amount of gas generated. Thanks dude!

  • @alonso336

    Any organic material including food, newspaper and leaves.

    You control the liquid level by draining the fertilizer valve periodically.

    You can add materials anytime that you want. Materials will dissolve over time at different rates.

    Keys to effective operation are temperature, the warmer the better, particle size of waste product, smaller the better. Good luck.

  • Shoulda' known, Vaaders dietary skills involve 'Capturing small Engines, People & Planets'.

  • I will make a biodigester, but I'd like to know for example with 5 kg of biomass for how long would you have continuous flame? thank you

  • @LordVaader

    IIIIIIIIIIIIIII SEEWATYADIDTHERE!

  • One tomato per 55 gallon set up. I might look at wood gas ideas instead.

  • @elBrechtel pig and fowl dunks are the best they are free and esy to get i would even be using fowl dunks cos we have poultry which would be of no waste for me
