When it comes to energy use, the company
has introduced an intelligent system that not
only protects its operations against the power
interruptions that are common in areas of
operation, but also ensures a higher level of energy
efficiency. It was the first cement company in the
world to be certified EN 16001, which is designed
to continuously monitor and document energy use,
identify action targets, and provide the necessary
resources and employee training.
The company uses biomass in captive power
plants. It also reuses bed ash waste, which
contains unburned particles of carbon, as a fuel in
the production of the clinker material for Portland
cement.
All cement makers are challenged to lessen the
impact of clinker, which must be heated to an
extraordinarily high temperature. Shree Cement
therefore minimizes the use of clinker, having
developed processes allowing for an increase of
the fly ash content in its cement as an alternative.
It became the first company in the cement industry
worldwide to register “Optimal Utilization of Clinker”
by the United Nations Framework Convention on
Climate Change (UNFCCC), resulting in 0.45 million
certified emission reduction units.
Shree has developed several innovative processes
to use what is normally considered waste. The
company was the first to develop in-house
processes for converting low-quality limestone into
gypsum, which can be used in the production of
cement. In addition to this, Shree makes use of
lead zinc slag waste, and has thus far consumed
0.8 million tons. The company has also been able
to fuel its heat power plants with petcoke.
Operating in a water-scarce region of India, Shree
Cement has also made a point of reducing its
water consumption. It has constructed a small
artificial lake for the harvesting of water to minimize
emissions as well as reduce waste. The company
is currently installing a 300 megawatt power plant
