I have been searching for some method of using the food waste, decomposable organic material and kitchen waste efficiently, and came across information on producing bio-gas from organic waste.

The bio-gas produced from food waste, decomposable organic material and kitchen waste, consisting of methane and a little amount of carbon di oxide is an alternative fuel for cooking gas (LPG). Also, the waste materials can be disposed off efficiently without any odor or flies and the digested slurry from the bio-gas unit can be used as an organic manure in the garden.

Components of the Bio-gas Plant

The major components of the bio-gas plant are a digester tank, an inlet for feeding the kitchen waste, gas holder tank, an outlet for the digested slurry and the gas delivery system for taking out and utilizing the produced gas.

This project is also useful for students to have a hands-on learning experience in constructing a Mini Bio-Gas Plant, using locally available material.

Material Required:

1. Empty PVC can 50 ltrs capacity: 1 No. (to be used as Digester Tank)
2. Empty PVC can 40 ltrs capacity: 1 no. (to be used as Gas Holder Tank) (Make sure the smaller can fits inside larger one and moves freely)
3. 64 mm dia pvc pipe: about 40 cm long (to be used for feeding waste material)
4. 32 mm dia pvc pipe: about 50 cm long (fixed inside gas holder tank as a guide pipe)
5. 25 mm dia pvc pipe: about 75 cm long (fixed inside the digester tank as a guide pipe)
6. 32 mm dia pvc pipe: about 25 cm long (fixed on digester tank to act as outlet for digested slurry)
7. M-seal or any water-proof adeshive
8. Gas outlet system: Please see Step 4 below for required materials and construction

Tools required

Do not require many tools here. A hack saw blade for cutting the cans & pipes and a sharp knife for cutting holes on the cans are all the tools we need.

Additional accessories

A single burner bio-gas stove or a Bunsen Burner used in school laboratories

I have constructed the mini biogas unit and loaded it with the stuff. I am not interested in the gas but I am excited about it as waste disposer

good construction. Where are the feed pipe and outlet pipe...?

feed pipe is on the top and the outlet on the side. covered the sides with paper.

I have covered the feed pipe with a plastic bottle and the sides with paper to prevent foul smell if any. BTW, will there be any foul smell?
antoniraj (author)  pednekarryesterday

it is better to keep it in the open. there will be mild smell in the slurry but not much. how do you propose to use the gas ? Methane is odorless and highly explosive. so take care

I have kept it in open. I intend to release the gas when it builds up.

ok... nice

good.! :)

Hello sir, thank you for uploading such a specific plan! I wish to use this plan for a school project so could you please send me the details to jany1235@naver.com ?Thank you!

i am so happy with your project,i am a social worker & I am planning for setting up a bio gas plant for our village but plant will be bigger i think so i am confused about layout. Can you please help and share me an idea to proceed further and plz help me with the details about layout and other things of the project?

I have mailed you construction plan of a Fixed Dome Biogas plant. Please go through the document.

I want to make it for my house .
Can you tell me how efficient this small plant is.
or can you please send me the layout of the more efficient plant of this size only

antoniraj (author)  AbheyM4 days ago
this is a prototype working model to show how Floating type Biogas plant functions. This will produce very little amount of gas which will burn in a Bunsen burner for few minutes. if you want to construct for your home, please go through my other instructable on constructing a medium sized Biogas plant at this link...

Dear sir,

We are trying to build a commercial biogas plant for food material.I wanted to know what are the waste that are generated. Is it a solid waste or a liquid waste which can be drained out

antoniraj (author)  RwijuP6 days ago
The out put generated is liquid slurry. It is not waste. It is a well composted material which can be diluted and used directly for plants.

hello sir am happy to know how to make the biogass my question to you is,if i have enough gass ,will i be able to refill the ordinaly gass cillinder,please email me how if there is any way my mail adress, john.iguanya@gmail.com

thnkx

antoniraj (author)  jiguanya6 days ago

you also require costly equipment for bottling Biogas in cylinders

antoniraj (author)  jiguanya7 days ago
No, you can not just refill ordinary gas cylinders (LPG) with biogas. Firstly you need to purify the gas, that is removing unwanted gases like carbon dioxide and Hydrogen Sulphide

do we need any permission from any govt department to install domestic boigas plant to replace lpg completely at homes

antoniraj (author)  amitsingharya7 days ago
I think no permission is required from any government department

hi sir ,

i am so happy with your project ,but i have some doubts on it,is it possible to get your contact no :u can catch me on 9052945121

kindly post your doubts here so that others can also get clarification from those comments and replies

please go through construction plan sent to your mail

sir can u upload a video clip showing the working of the above explained plant

or mail me @ akshayrlz92@gmail.com

antoniraj (author)  akshay.sanaki8 days ago

it is a prototype... I did not have any video of its working. However you can find more information in my other instructable here...

Hii sir,

I want to know about your idea.is any need of chemical to mix in that waste?.and it is possible to produce only by kitchen waste .how much gas produced from how much waste?.pls reply at sourabhpatil206@gmail.com
antoniraj (author)  sourabhp13 days ago
No chemicals are to be mixed with the feed material... you can use all types of organic waste other than onion peels, egg shells, garlic peels and more fibrous substances (like coconut waste etc.)

Dear sir this prototype biogas plant is very good but i confuse for what quantity produce of biogas and whats qty of dung used in per day basis.pls send the details of composition required and produce gas Qty. me this mail id "pavanjadon.jadon@gmail.com "

antoniraj (author)  PavanJ14 days ago
You can feed about 350 to 400 grams of cow dung in this plant. This is a prototype and the gas produced is very less. this model can be used for science fair projects, not for home use.

Please also go through my other instructables on biogas at the following links to get a clear idea about a medium sized biogas plant
