The India’s 1st Green Rail Corridor is a 114-km long Rameswaram-Manamadurai stretch in Tamil Nadu.
Trains in the segment have been equipped with bio-toilets to ensure zero discharge of human waste on the rail tracks.
In these toilets, anaerobic bacteria – developed by DRDO and hence called ‘DRDO Bacteria’ – converts human waste into water and gas which is released through outlets. Water is subjected to chlorination and then discharged outside.
In the long-term impact will be a clean and environmental- friendly track that also facilitates a healthy working condition for those working on railway tracks.
Before end of March next year, the line to (from Jammu) Katra will also be human waste free.
