For years there was no escape from the smell of cowdung and menace of mosquitos for the residents around a dairy in one village of Delhi. And then a biogas plant set up by one Delhi University professor changed the scenario.
The dung is now collected every day for the plant, which produces biogas and bio-manure.
Set up with technical support from IIT Delhi, the biogas plant stands on a plot of farmland about a furlong from the nearest households of the village. It spans 400 square yards.
The plant processes 500 kg of cow and buffalo dung daily, collected from the village and the diary. It produces 20-22 kg of methane a day.
