Waste Management Analysis In Trains Using Anaerobic Bio Digester
Railways are the major means of transportation. One of the commitments of the railways is to provide safe and
dependable train services to passengers and ensure adequate passenger amenities in trains and at railway stations, which
includes provision of clean and hygienic surroundings both at trains and in stations. Stagnation of waste on tracks is
common, near stations and railway tracks. Apart from the poor hygiene, this causes discomfort to the passenger’s onboard
trains, when they stop near the stations. It is a matter still requiring attention and education in developing countries. The
issue of dealing with fecal matter is a significant problem and needs multi-dimensional efforts.
The problem of environmental degradation and corrosion of tracks due to night soil has caught the attention of railways for a
long time. The traditional method of disposing human waste from trains is merely to deposit the waste onto the tracks is
known as a ‘Hopper Toilet.’ The principal drawback is the method is crude or unhygienic. The current study focuses on
waste management in trains using Anaerobic Bio digester. Four variants were designed and developed to address the
problem faced. It was observed that no fecal matter noticed in discharge from the toilets so far in any of the coaches, no foul
smell noticed in general in these toilets. The tests parameters for TDS, TS, pH, volatile solids and COD were generally to
defined levels and neat & clean under-gears encouraged maintenance staff to work more efficiently.
