The aircraft-style bio-vacuum toilets are based on sustainable cleanliness as the vacuum evacuation system helps in the elimination of the foul smell and also saves a considerable amount of water in regular consumption. Scientifically, in the bio-vacuum toilet, human waste is discharged into a biodegradable tank system and converted into organic matter through composting, which reduces the bad odour as well as the consumption of water. This step enhances the passenger experience during long hours of travel. According to Indian Railways, vacuum toilets are generally fitted in aircrafts.
In all, bio-vacuum toilets, stainless steel dustbins have been provided for the safe disposal of napkins, bottles, garbage etc. Steam taps are also provided in these toilets which sense the difference in the steam and liquid draining out from the pipeline, and the automatic valves ensure that the bio tank does not overflow. Apart from this, a trolley mounted mobile sewage evacuation machine is being utilized for the disposal of the bio toilet waste from the train coaches.
