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.

How can I clean the gas for safety sake since you didnt mantion anything about that. The gas produce from this will surely produce hydrgen sulfide which is bad and poisionous apart from the Methane gas produce?

Thanks

I still don't understand why this outlet is for? I see there is also a bucket with waste coming out of the outlet. How does this happen? Can you explain it Sahas? Thanks in advance.

I was in a hurry. I got my doubt cleared while reading rest of the comments and your answers. I think, if at all I have to observe my method, then I have to put another valve to the outlet. What do you say?

Hi! Chitlange Sahas, felt glad on seeing your project. I have a doubt. Doesn't gas leak from the outer edges of the gas holder tank? Do we need a gas holder tank really? Can't we install the valve (plumbing purpose) directly to the lid of the digester tank.

This is a good explanation of a working biogas generator.

I can
suggest you put a plastic ring, or several plastic knobs around the
middle of your collector pail, it will help guide it up straight.

Thank you for posting.

sir ,you told that after putting cow dung in tank first time wont get gas , daily can put cow dung to get gas ? or how long days wait for to get the gas. how can i take the gas from tank

Chitlange Sahas (author)  p.s.joe.arul3 months ago
it takes about 15 days for first time to earn out gas from the system.. never do the mistake of adding dung daily !! it will damage sysytem forever.. you will have to repeat everything from start!!. you wait for few days and yes do test the acidity level..

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

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

coimbatorean4 months ago

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

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.

Chitlange Sahas (author)  sameer.baisoya.94 months ago

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

Chitlange Sahas (author)  sameer.baisoya.94 months ago

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??

arjunps8 months ago

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)  arjunps5 months 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
