The North Western Railway has declared the Barmer-Munawab and Pipad Road-Bilara rail routes in Rajasthan as Green Corridors.
With this total number of green corridors has increased to three.
The 114-km-long Manamadurai– Rameswaram stretch of Southern Railway was India’s first ‘Green corridor’.
What is Green Corridor: Know More- The Green Corridor ensures zero toilet discharge on rail tracks as part of its commitment to clean environment under the ‘Swachh Rail-Swachh Bharat’ initiative.
- Trains in the section have been equipped with bio-toilets to ensure zero discharge of human waste on the rail tracks and preventing corrosion of the tracks.
- Indian Railway had developed the environment friendly ‘Bio-toilets’, in association with Defence Research and Development Organisation (DRDO).
- Bio-toilets evacuate discharge into a biodigester tank, containing anaerobic bacteria, fitted underneath the train coach in a small space.
- The bacteria convert human faecal matter into water and small amount of gases (including CH4) by process of hydrolysis, acetogenesis, acidogenesis and methanogenesis.
- Indian railways aims to install human waste discharge free bio-toilets in all its coaches as part of the Swachh Bharat Mission by September 2019.
