Bhabha Atomic Research Centre Biogas Plant

Can you tell me in detail about the Akruti Technology Package for Rural Deployment offered by Tech Pack Technology: Bio-gas plant based on biodegradable waste (Nisargruna) of Bhabha Atomic Research Centre?

[Shaleen]

Three Akrutis have built up the Bio-gas plant (Nisargruna). At Akruti-Parivartan electricity generation was demonstrated by connecting 10kW, biogas generator to Nisargaruna Biogas plant. The composition of biogas is:

Methane (CH4) : 70-75%
Carbon Dioxide (CO2) : 10-15%
Water vapours : 5-10%

Advantages
Bio Gas Plant would serve purposes like:

• Environment friendly disposal of waste, which is need of hour considering mass pollution everywhere.

• Generation of fairly good amount of fuel gas, which will definitely support the dwindling energy resources.

• Generation of high quality manure, which would be weedless and an excellent soil conditioner. This is very important for restock fast decreasing resources of productive soils. For reload the soil with high quality organic manure has been identified in tenth five-year plan.

• It would reduce the threat of street dogs and other nuisance animals.

• Biogas is a colourless, odourless and inflammable gas. The gas generated in this plant can also be used as a source of natural gas.

There is a definite need for developing means to handle enormous amounts of biodegradable waste that is generated daily.

The waste organic matter that is generated in the kitchens can be processed using modified biogas plant.

Applications
The wastes are processed by Bio gas plant are biodegradable kitchen waste, paper waste, green grass, leaf litter, animal remains in abattoirs, hospital waste, green plant waste, gobar, crop residues, sugarcane, baggase, and water hyacinth.

The plants are useful for Municipal Corporations, Hospitals, Hotels, Housing Societies, Govt. Establishments, Abattoirs, Nagar Palika, Grampanchayat, Farmers.

Operation

The material to be processed is brought to the plant site every day. Two workers are needed for the operation of the plant. The important tasks to be done are:

• Sorting of waste materials
• Processing the waste in mixer
• Routine operations for predigester and digester tanks
• Manure pits

Infrastructure Required
The following infrastructures required for set-up a 1 tonne/day capacity Bio gas plant:
• Space : ~ 300 m2
• Manpower : Two unskilled persons for operation
• Power supply : 3 phase AC
• Water Supply : 1.2 kL for one tonne plant

Current Status

Presently 40 plants are operating based on the technology with a capacity 1 Ton/day to 5 Ton/day and around 40 plants are in construction.
