In bio-toilets also called green toilets, a colony of anaerobic bacteria convert human waste mainly into water and small amount of gases (methane and CO2) in the bio-toilets has been fitted underneath the lavatories in coaches. The gases emit into the atmosphere and waste is discharged after chlorination onto the track.
Human waste thus does not fall on the railway track.
This procedure is environment-friendly and improves the working condition for the railway track staff. According to railway officials, defacement and corrosion of railway tracks by night soil cost the exchequer in crores. The bio-toilets has the advantage of preventing corrosion of railway tracks, as it prevents discharge of human waste from the coaches. So all new coaches inducted into Railways will now come fitted with bio-toilets.
RCF in association with DRDE (Defence Research and Development Establishment), developed this highly cost effective indigenous technology for treatment of faecal waste in coaches. The technology provides an almost maintenance free and a low cost solution to the problem of open defecation on the railway tracks.
On being asked the production of coaches in current fiscal year, he added," We are targeting to produce 1523 coaches this year against the installed capacity of 1,500 coaches per annum. Till date we have produced 1300 coaches of different variants like Rajdhani, Shatabdi, and other mail/express trains.
