"We are the first one to launch bio-gas bus in the entire south east Asia. Now old buses which have run for 15 or 20 years, can also be given a fresh lease of life with this clean and cheap fuel, and we are in the process of seeking government approval for the same," Phoenix India Research chairman and managing director, Jyoti Prakash Das said.
Four more buses will be rolled out in the current month and another ten by the end of this year, Das said.
Presently, the lowest fare in a Kolkata bus is Rs 6.
The first bus will run a distance of 17 km between Ultadanga and Garia in the southern fringes of the city and Phoenix India will run the bio-gas service from its Corporate Social Responsibility fund.
