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 a Waste Food Crusher installed which makes slurry of the left over food. I never counted how many Kg of slurry goes away. I would like to know how does the conversion work? How many Kg of Bio-gas will be produced if there is 10 Kg of slurry? Also, is there a time period when the used slurry has to be removed? Last question: Do we have to mix cow dung in the slurry?

antoniraj (author)  ranjan.konhalikar15 days ago
The output from the waste food crusher is mostly water. A normal household may produce about 1 to 2 kilograms of kitchen waste. The biogas production is counted based on the solid wastes and not on the slurry. one kilogram of organic waste may produce between 150 to 200 grams of biogas, depending on the type of waste. In a biogas digester, you need not to remove the slurry manually. when you feed fresh waste, the digested slurry will be automatically drained out through the outlet pipe. It takes about 30 to 40 days for a solid waste to get fully digested. Cow dung is required only to start the anaerobic digestion process. Afterwards it is not required

Hi! This is a very helpful instructable you have uploaded to share to others. Our schools in the Philippines would surely benefit from this. Please, can you also send me the details of how to construct this project? I know our students will appreciate this very much. Again, thank you for sharing this with us.

please see the attached file sent to your mail. methane is highly explosive, take care when experimenting with students

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

antoniraj (author)  pednekarr1 month ago

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.
temp_1535758607.jpg
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)  pednekarr1 month ago

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.! :)
