A city based engineering major has inked an agreement with a Denmark-based firm and the Defence Research Development Establishment (DRDE) to develop ‘green toilets’ for railways to keep trains, platforms and tracks clean and free from filth and corrosion.

“Under the railways ambitious green toilet scheme, two types of toilets based on vacuum and bacteria technology would be installed in trains in order to keep them green and clean,” Daulat Ram Industries Chairman and Managing Director, Mr Satish Sharma, said here today.

The toilets, which will function on vacuum technology, would be installed in Rajdhani and Shatabdi express trains as per the plan of the railways, while biological (bacteria)-based toilets would be installed in other trains.

Vacuum toilets are like those at present operational in aeroplanes in which one needs to collect the waste at terminal points and make arrangements for their disposal, Mr Sharma said.

“It is good for aeroplanes and AC trains but not for the other types of trains for which the railways has decided to install biological toilets.”

“The railways has made a provision of nearly Rs 800 crore for installing vacuum and biological toilets in trains in a phased manner,” Mr Sharma said.

For producing vacuum toilets the company has inked an agreement with the Denmark-based Glova company, while for making biological toilets it has borrowed the technology from DRDE at a cost of Rs 25 lakh.

The company will also pay royalty to DRDE for using this technology to produce bacteria, which will convert the waste material into liquid form and dispose of safely when the train reaches isolated places.
