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

hello sir,

am working project on biogas generation from food and market waste please send me how to increase rate of reaction and also which type of vegetable waste and fruit waste should not be added to digester

my email id is bhuimbar@gmail.com

antoniraj (author)  bhuimbar9 days ago
you can use all type of food and vegetable waste. Avoid using onion skin, garlic skin, egg shells, seeds of fruits, wastes containing lots of fiber and bones. You can not just increase the rate of reaction but can achieve constant rate of gas production by proper feeding with respect to the capacity of the plant

i hav a bio gas plant in my hom for the last 2 , 3 years but now gas is not coming or filling in it can i pls know wat is the prblm and how i can solve it

antoniraj (author)  arjun6211 days ago
Please mention the capacity of Biogas plant and the type & quantity of feed material used per day

Hi Antoni,

1.) How much dung needs to be added to start with?

2.) How much dilution is needed?

3.) Should we add dung at regular interval or only to start with?

Rahul

antoniraj (author)  pednekarr115 days ago
To start with you need to fill the digester with diluted cow dung to about one third of its depth. If you can get hold of more cow dung it is good.
Dilute per kilogram (Approximately) with 4 to 5 liters of water. More water no harm.
It is not necessary to add cow dung at regular intervals, but if it is available you can add it.

Thank you, Antoni.

you can also go through my other instructable on a medium sized biogas plant for home use here:

http://www.instructables.com/id/Constructing-a-Medium-Sized-Biogas-Plant-Using-Kit/

antoniraj (author)  anjali.yadav.5209015 days ago
good construction for a prototype. you should have fixed the outlet pipe somewhat higher than present position. this would have increased the digester capacity. did the feed pipe (larger one on top) go all the way down ? otherwise gas will escape through that. Also check all the joints with soap water to find any leakage. Methane is lighter than air and it will escape from the container even if there is a small leakage. I hope you have not used chlorinated water for diluting cow dung.

Secondly, this type of small models are for demonstration purpose only. You will not get much gas from this and the pressure from this is insufficient to be used in a biogas stove. This is suitable for a bunsen burner for a few minutes burning only

I hv made it as instructed....but after 15 days...no output....
antoniraj (author)  anjali.yadav.5209020 days ago
If the climate is cold then it may take few more days to produce gas. Check that there is no leakage and also you have not used any chlorinated water. Post a picture if possible
