Q95. Nisarga-Runa technology developed at Bhabha Atomic Research Centre is:
(a) A solid waste management technology.
NISARG-RUNA plant for solid waste management is an indegenous biogas plant developed by the Bhabha Atomic Research Centre under the Department of Atomic Energy. The Nisarga Runa technology offers a Zero garbage, Zero effluent method for waste management. A conventional plant can handle only gobar & / or human waste.
NISARG-RUNA plant can process almost any biodegradable waste including kitchen waste, paper, grass, gobar, dry leaves etc.
There is a good potential for energy generation in this biphasic biomethanation plant.
A substantial portion of our biodegradable waste is food waste (38-40%) which is used to generate methane. This methane gas can be used as fuel for domestic purposes or in vehicles.
The vegetable waste and paper waste yield manure. Manure obtained from such waste has high nitrogen contents.
This manure acts as an excellent soil conditioner.
The plant returns as organic manure that is 10% of the total waste processed.
The carbon to nitrogen ratio of this manure is 12:1 (similar to fertile land).
It has phosphorous, potassium, iron and magnesium in small quantities. It is weed free and does not have any offensive smell
