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 did nt under stand what is the use of guide pipe.and how the external small pipe release slurry.plz......explain.
antoniraj (author)  naresh-12313 days ago

you can make without the guide pipe also, but this will make the gas holder to tilt to one side when it raises up. Guide pipe helps the gas holder to stay straight.

When you add more waste mixed with water, the slurry level tend to raise inside digester. As there is a opening and an outlet pipe, the slurry will fall through the outlet pipe. The slurry will be almost like water

what is the use of the guide pipe fitted with the gas holder tank? as the diameters of the guide pipes fitted with gas holder tank and digester tank are the same, how can the pipes be interlocked?

my email id is sourajitm8@gmail.com

antoniraj (author)  SourajitM26 days ago
the diameters of the guide pipes fitted with gas holder and digester tank are not same. please see step 3 for diameters of each pipe
