Thermax as an organisation is committed to sustainable
development. Sustainability for us is not only a criterion
applied to the energy and environment related solutions
that we provide, but in fact pervades day-to-day activities,
informs key decisions and guides new initiatives. In pursuit
of achieving the Thermax vision of sustainable
development for society, the Boiler & Heater Group has in
the recent past delivered several breakthrough innovations
through a combination of in-house R&D and global-
sourcing of the best available technologies. Among these
are for distilleries,
for urban waste disposal,
and
for power
generation. The B&H Group is also working on a range of
products for the emerging market for
spent wash-fired boiler municipal solid
waste-fired boiler waste heat
recovery boiler for cement plants internal-
recirculation circulating fluidized bed boiler
solar energy based
heat recovery systems.
Our Green BusinessPhilosophy and Activities
04
Ms Meher Pudumjee
Chairperson
“When business organisations consider moving to
decisions that are sustainable -- like saving electricity,
recycling water, using renewable energy or putting up
green buildings -- the big investments required upfront
would certainly impact the balance sheet here and now.
But, if we were to think of a longer time-frame, all these
decisions would make a lot of sense when we consider the
concept of life-cycle cost -- a higher capital cost, but with
far lower operating costs such that it pays for itself over the
life of the product. Long-term sustainability also goes hand
in hand with the kind of decisions we make, processes we
follow, policies we adopt and the values we propagate.
Companies passionate about the cause of Sustainable
Development will constantly come up with innovative
solutions which, over time, will definitely add to the bottom
line. If we were to redefine success of an organisation as
achieving the triple bottom line -- economic, environmental
and social -- it would be a sustainable model and we would
be a far happier and healthier species on earth! So what can
each one of us do? What can we do as an organisation to
achieve this triple bottom line? These are questions we
need to ask ourselves and act as quickly as possible since
time is running out."

A Case Study

R .R. Energy Pvt. Ltd. has set up a 14 MW biomass-based power plant at Garh
Umaria / Darramuda, Raigarh district, Chhattisgarh. The unit started commercial
production of power from January 13, 2007. The generated power is sold to the grid
for a remunerative tariff.
R. R. Energy was promoted by the Raipur-based Hira Group, whose other group
companies include Hira Ferro Alloys Ltd. and Godawari Power & Ispat Ltd.
Among the other notable features of the project is the use of air-cooled condenser
instead of a cooling tower to help conserve water. Also, ash from hoppers and ESP is
conveyed to an ash silo and later transported to cement plants.
Special design aspects of boiler help ensure maximum availability and efficiency of
boiler.

Cement manufacturing is a highly energy-intensive process. Given thefragile and dynamic nature of the fuel and power situation faced by cementplants today, it makes sense for them to adopt waste heat recovery basedsolution for the following reasons:
Greater energy security (helps meet upto 35% of power requirement)
Improved competitive positioning
Regulatory push (Policies mandating use of minimum 5-10%renewable/WHR energy are already in place in several states)
