Bio-Toilets
- Indian Railways has developed environment friendly ‘Bio-toilets in association with Defence Research and Development Organisation (DRDO).
- Bio-toilets evacuate discharge into a biodigester tank, containing anaerobic bacteria, fitted underneath train coach in small space.
- The bacteria convert human faecal matter into water and small amount of gases (including methane) by process of hydrolysis, acetogenesis, acidogenesis and methanogenesis.
