Development Cell of the Railway Board has come up with a design that combines the advantages of Vacuum toilets and those of Biotoilets to create a new design of Hybrid Vacuum Toilet
A prototype has been made by modifying the standard flushing protocol of a vacuum toilet so as to create water seal and additional post flush cycles and this concept has been converted into a working prototype by Indian Railways.
This newly developed toilet has been fitted in Dibrugarh Rajdhani for trail.

Features of the Hybrid Vacuum Toilet:
The prototype consists of a custom designed Vacuum toilet adapted from a commercially available vacuum toilet that is used in aircrafts which evacuates its discharge into a biodigester tank.
The biodigester tank is fitted underneath the coach and contains anaerobic bacteria that converts human fecal matter into water and small amount of gases before discharging the same on the ground/track.
Typically, a conventional toilet or Biotoilet uses 10 – 15 liters of water per flush whereas the vacuum toilet consumes only appx. 500 ml of water for flushing.

NOTE: There is no retention tank at the bottom of the coach. The waste is discharged on the ground only.
Bio Toilets:
Bio-Digester Toilet is a decomposition mechanized toilet system by means of which the sludge(Human Waste), the fecal matter is decomposed to bits in the digester tank using a specific high graded bacteria further converting them into methane and water, discharged further to the desired surface.
The Bio-digester toilet is total maintenance-free system & does not require any sewage system. The specific high graded bacteria involved in these bio-digester toilets carries on to further auto generation on their own because of their supreme quality.bio toilet train india
Bio-toilet technology is based on anaerobic biodegradation of organic waste by unique microbial consortium and works at a wide temperature range. The bacterial consortium degrades night soil at temp as low as -20 degree C and produces colorless, odorless and inflammable gas containing 50 – 70% methane.

Salient features of bio-toilet:
Suitable for sub zero temperature of Himalayan Region, Glaciers, Railway coaches, Buses, Highways, Remote areas, sea ports, Mining area, metro cities etc.
Suitable for Mobile Toilet applications
0% maintenance free, continuous biological process.
Complete elimination of pathogens.
Economically viable.
No dependence on the limited and costly conventional energy sources.
Can be installed and made operational in 12 hours only.
Inoculums charging is only once during the entire life of Bio Toilet.
No need of connectivity to the sewage line, septic tank. No disposal of sludge is required
