evidence: These bio-toilets have specially developed bacteria to break down and digest the solid part. The only discharge is liquid that is recycled for further use like flushing. These toilets are easy to install with very minimalistic maintenance requirements. No additional energy is required as the toilet do not require electric-motor driven mechanism. These bio-toilets are easy to maintain and ensure maintenance of hygienic conditions at tracks and railway stations. [...] Despite the promising setup, engineers lament on the lack of awareness among the cleaning staff or ‘safaiwalas’. Once fitted, the bio-toilets can function for almost two years with little maintenance. But, the staffs are not adequately trained on the new technology and they resort to their traditional cleaning methodologies with the help of disinfectants and acids, causing more damage. In addition to this, train maintenance staff complain about apathy among the passengers, who despite the signs, dump items like diapers, plastic bags, bottles and sanitary napkins into the toilet, rendering the system ineffective.
