Green Train Corridors-Prelims-2017

  • The Union Ministry of Railways has declared the Okha-Kanalus and the Porbandar-Wansjaliya railway sections of Gujarat as Green Train Corridors. All trains passing on these 175-km long lines (141-km-long Okha-Kanalus route and the 34-km-long Porbandar-Wansjaliya route) are now equipped with bio-toilets. On these routes, about 29 trains consisting of nearly 700 coaches have been equipped with bio-toilets to prevent open discharge free zone on tracks as part of the Swachh Bharat Mission.

About Green Train Corridors:

  • • Green Train Corridors are sections of the railways which will be free of human waste discharge on the tracks. Trains running on these corridors will be equipped with bio-toilets.
  • • Thus, it will completely stop discharge of human waste from trains onto the ground which in turn would help in improving cleanliness and hygiene.
  • • The 114-km long Rameswaram-Manamadurai section of Tamil Nadu was made the India’s first Green Rail Corridor in July 2016.

What are Biotoilets?

  • The environment-friendly bio-toilets for passenger coaches were developed jointly by Indian Railways and Defence Research and Development Organisation (DRDO). In the bio-toilet fitted coaches, human waste is collected in biodigester tanks below the toilets and is decomposed by a consortium of anaerobic bacteria. By the process of hydrolysis, acetogenesis, acidogenesis and methanogenesis, the anaerobic bacteria converts human faecal matter into water and small amount of gases (including methane).

Background:

  • The Union Ministry of Railways has taken up a mammoth task of equipping human discharge free bio-toilets in all its coaches by 2021-22 in order to contribute to mission ‘Swachh Bharat Abhiyan’. It aims at completely stopping discharge of human waste from trains onto the ground in order improving cleanliness and hygiene.
