The 'Bio-Toilet project' of Indian Railways is an innovative and indigenous development of technology. This technology is first of its kind being used by any railroad in the world for On-board accelerated digestion of human waste. These bio-toilets are fitted underneath the lavatories and the human waste discharged into them is acted upon by a colony of anaerobic bacteria that convert human waste mainly into water and small amounts of bio-gases.

The gases escape into atmosphere and waste water is discharged after chlorination onto the track. Human waste, thus, does not fall on the railway tracks thus improving cleanliness and hygiene at platforms, and facilitate track and coaches maintenance staff to perform their work more efficiently. Indian Railways' 100-Day Plan: Reducing Delhi-Howrah, Delhi-Mumbai Travel Time by 5 Hours.

It has been developed jointly by Indian Railways' Engineers & DRDO's scientists. It is one example where the technology developed for defence applications has been utilised for civilian purpose.
