Meher Pudumjee, 

Pudumjee's focus has always been on keeping her company green. So, acquiring 33% in Pune-based First Energy made perfect sense, as the company makes biomass stoves for homes and commercial use. Thermax continued its efforts to find greener alternatives for its core business of boilers and captive power plants. Financially, FY15 was not a bad year for the company, with revenues registering a 10% increase to Rs 4,808 crore.
