ANSWER: Indian Railways
- The first prototype of a 'hybrid vacuum toilet' has been installed in the Delhi-Dibrugarh Rajdhani.
- The prototype consists of a custom designed vacuum toilet adapted from a commercially available vacuum toilet that is used in aircraft.
- The toilet evacuates its discharge into a biodigester tank which is now successfully proven in the bio-toilets that are already in use in many other trains run by Indian Railways.
- The biodigester tank is fitted underneath the coach and contains anaerobic bacteria that convert human waste into water and small amount of gases before discharging the same on the track.
- The design has been devised by the Development Cell of the Railway Board and combines the advantages of vacuum toilets and those of bio-toilets to create a new design of 'Hybrid Vacuum Toilet'.
