Bio-Toilets in Indian Railway

Uzhavan Express that was flagged off from here on September 1, qualifies to be called a ‘green express’ as bio-toilets have been fitted into 34 of its 36 coaches. “Except first AC and AC two-tier coaches, all the other 34 coaches have been fitted with bio-toilets,” said Southern Railway officials. 

The first bio-toilet-fitted train, Gwalior-Varanasi Bundelkhand Express, has been running since January 2011

Indian Railways, at present, is running 1,400 coaches with 3,800 bio-toilets in various trains, according to a Southern Railway press release issued here on Thursday Sep 5,2013

The tank has seven chambers. By the time the excreta traverses through these chambers and reaches the exit, it is fully decomposed
