Select the correct code.
The correct option is C (c) Both 1 and 2
The bio-toilets are fitted underneath the lavatories and the human excreta discharged into them; these toilets incorporate microbes with an anaerobic digestion process to digest human waste. A colony of anaerobic bacteria acts upon the collected waste and converts the waste into water and biogases (mainly methane and carbon dioxide). While the gases escape into the atmosphere, the wastewater is discharged after disinfection onto the track, thus putting an end to the crisis of railway tracks strewn with excreta.
Each bio-toilet requires 60 litres — or three large bucketfuls — of inoculum, a mix of cow dung and water. This inoculum begins the process of breaking down 3,980 tons of human excreta. Anaerobic bacteria are abundantly available in cow dung.
