Smart Indian Railways: An Environment Friendly Model

In recent years development of Indian railways took place rapidly, but still there are many issues related in the way of growth. The biggest issue is the creation of world’s biggest open toilet. In every coach there is an open toilet system through which feces and urine of human is discharged directly on the tracks, which results corrosion of track components. Another issue of food waste on platforms and through the train canteens, which is another big headache for Indian railways. Several models of green toilets have been proposed for the purpose of improvement in the environment and hygiene like development of Controlled discharge toilet system (CDTS) built by DRDO based on train speed, development of Zero discharge toilets (ZDTS) by Research Designs and standards organization Lucknow and IIT Kanpur. These systems are tried by railway but rejected. These systems are not suitable for trains because of its infrastructure complexity, expensiveness and large number of people will use them. Therefore there is a requirement of proper sanitation in the Indian railways. In this paper a model is proposed which produces energy and fertilizers from toilet waste and food waste which can be used for thermal generation, electric generation, cooking, agriculture and some other purposes.
