Picture of Biogas at home- Cheap and Easy
Hi there, I am Sahas chitlange, aging 14, from India. here is my homemade cheap and easy to build mini Biogas plant. It burns for approx. 20-30 mins on a bunsen burner. you can add anything from your kitchen waste ( Exept Onion peels and eggshells). In 12 hours the Gas is ready for use. It is very easy and cost effective to build (only 2-3 dollars) and gives many useful products.

the end products of this system are:
1) Methane : (Can be used as a fuel)
2) Slurry     : (the spent slurry is exellent manure)

The main components oof this system are:

1)  Inlet pipe
2) digester tank
3) gas holder tank
4) slurry outlet pipe
5) gas outlet pipe

Step 3: Fix the inlet and outlet pipes

Glue the Inlet pipe and the Outlet pipe with any water proof adhesive. 

Step 5: Time to mix the cow dung !

mix the cow dung (5kg for 50 liters) and add water to  make a fine slurry. Now put the slurry in the digester tank.

Step 6: Almost finished!

Picture of Almost finished!
Put the gas holder tank overturned in the digester tank after adding the slurry . REMEMBER: open the valve while putting the gas holder tank. the mini plant takes 10-15 days for the first time to get output. For the first time, the gas in the tank wont burn as it contains Carbon Dioxide gas, if fortunately it burns then good or wait for the second time. You can detect how much gas is there in this system, the gas holder tank will rises up as the gas is produced.

hi sahas actually i wnt to know which material except cow doung we should add to the digester tank for getting more amount of gas

can anyone tell me that how much gas can produced by following this procedure or is it enough to fulfill 3-4 hour cooking need??????? Chitlange Sahas

guys i am interested in making of methane gas from cow dung . plz share ideas

should we grind the all the kitchen waste (leftover food, veg cutting waste) into a paste before adding to the bio gas digester ?

Hi Sahas,

Great Job.

One Doubt should we grind into paste form all the kitchen waste like veg cutting wastes, leftover food etc before adding to the digester tank ?

My gtalk id is cbeiyer@gmail.com do add me on google talk so that i can discuss this with you further before i try to make one

Wish you a Bright Future

thanks for d info sahas.

its ur experience that heloed me to do my assi.....

You are welcome.

bro i have made a digester but the gas is not being produced in it.HELP me bro its my school project and only 20 days left for it.

also follow each step carefully you will suceed. Best of luck..............

Pls post pic of the digester and slurry ( the liuid in tank) also try checking the acidity with litmus the liquid should be neuteal orther wise add some base like baking soda to nutralize the mixture. Ask for further help if needed. Bye.

Post the pics immidiatelly......

hi sir. can we use other waste products instead of dung, like rotten fruits or vegetables to this biogas digester??

if you put on the slurry then how will the tank in the top, which is gas holder tank in top will remain at same it will float. how it will be in air tight position, the biogas will be loosened and let in the air...

Give me some suggestions, because i am doing this project for my diploma clge, and also send the details to my id arjunpsarathy@gmail.com.

Chitlange Sahas (author)  arjunps23 days ago

That wont happen sir.......... try with a glass and bowl of water

I have to plant Bio Gas Plant for domestic use,as such kindly intimate the procedure and expenditure/cost to be incurred for the same

Seems that you are from india

The total cost for me was around 1500 Rupees indian

thank u very much sahas. ur replies are very useful for me. my mail id is :- kalepa2203@rediffmail.com

prasadkale . the collector tank floating in the water slurry . and did you see the photo in step 3 . the pipes dont come in between the collector tank . The collector tank is freely floating in the slurry. and now see the photo in step 6 . the collector tank is without air . now after the process begins , the bacteria releases methane and the tank gets full of methane. the tank rises . for using the gas place some bricks on the bucket and connect a bunsen burner with help of pipe and use the gas.
Chitlange Sahas (author) 4 months ago
hello prasadkale . thanks for kind comment. The process that helps to produce the gas is Anaerobic digestion . the food feeded undergoes anaerobic digestion by the bacteria inside. when anaerobic digestion process is going on . the bacteria releases methane as byproduct. And as the gas is released the tank rises up. this way the system works. if you are having any problems feel free to ask . BYE.

And another thing is that in the step 3 u showing the inlet pipe and outlet pipe. i want to askthat how can we put the gas holder tank on this pipes in digester tank.

hello sahas,

i m student of commerce in third year of graduation. ur idea is amazing plz i want to try it at my home. can u help me. i cant understnd:-

1) how can we put the gas holder tank in digester tank , i mean when we put it overturned how can it produce the gas, then what is the distance between gas holder tank and digester tank.

i m very excited about this idea of biogas.
