"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, 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, he said.
Vacuum toilets are like those at present operational in aeroplanes in which you need to collect the waste at terminal points and make arrangements for their disposal, Sharma said.
"It is good for aeroplanes and AC trains but not for the other types of trains for which the railways have decided to install biological toilets."
"The railways have made a provision of nearly Rs 800 crore for installing vacuum and biological toilets in trains in a phased manner," Sharma, whose units have been producing several crucial parts for locomotives and air-conditioners among others for railways since 1973, said.
For producing vacuum toilets the company has inked an agreement with Denmark-based Glova company while for making biological toilets it has borrowed the technology from Defence Research and Development Establishment (DRDE) at a cost of Rs 25 lakh.
