New Delhi: Railways is finalising a proposal to manufacture new design eco-friendly toilets in Nagpur in a step towards its commitment for cleaner environment and to prevent damage to rail tracks.

"Efforts are on for installation of green toilets in trains and field trials are on for the purpose. These newly designed eco-friendly lavatories are likely to be manufactured in Nagpur," a senior Railway Ministry official said.

The proposal for manufacturing green toilets in Nagpur is likely to find a mention in the Rail Budget on February 25.

Railways is carrying out field trials for various types of green toilets, including controlled discharge toilet system, zero discharge toilet system and bio-toilet based on bio-digester technology, in about 90 passenger trains.

"Trials for bio-toilets based on bio-degradable technology are being carried out in Bundelkhand Express between Gwalior and Varanasi...These bio-toilets are in use in Siachen," he said.

The Railways had signed a MoU with DRDO for development for bio-toilets for rail coaches.

Rail tracks get corroded because of the discharge from toilets and the new design green toilets would prevent the damage to the tracks, the official said.

The feasibility trial for the zero-discharge toilet developed by RDSO and IIT where the solid waste is separated and the treated liquid is recycled for flushing is complete, he said.

The Railways is also considering to introduce vacuum retention toilet, like the one in aircraft, in all Shatabdi trains and preparations are afoot to go for global tendering for manufacturing of vacuum retention toilets, the official said.

However, the official said, "Rail users involvement and support is critical for the success of new system as objects like bottles, napkins, poly bags, gutka pouches and cigarettes would choke the new design bio-toilets."
