EnMS Rs. 5.4 lakh payback per year on EnMS implementation for 25 years.
Total energy saving over improvement period was (GJ) 38,303 GJ, Total CO 2
emission reduction over improvement period was 38,371 MT of CO 2.
Effluent treatment plant is used to treat the sewage from the cooling tower water
through the process of activated sludge process (ASP), secondary treatment process
also used and finally passed into the dairy farming, plantation and green belt.
4 Reuse of Treated Trade Effluent in Process
Investment of Rs. 3 Lakh as part of the initiative to conserve natural resources, Captive
Power Plant effluent (waste water) was used for internal water spray in cement mill
by which it was able to reduce the raw water consumption by approximately 80 KL
(kilo liter) water per day, leading to raw water conservation.
5 Discussion
The Cement plant falls under large scale industry and Red category (Annexure A,
in EIA). In Ariyalur in Tamil Nadu, calcium carbonate and gypsum was available in
higher quantity. Originally Installed capacity (Clinker), Installed capacity (Cement)

industry has adopted cleaner technology on process modification but Industry
ecology in air pollution control was still using conventional technology at the End
process. With Vertical roller mill inlet duct Modification the ROI was (−79.03%) but
still conventional technology has a loss but on CBR value of conventional technology
is 0.2341 higher that cleaner technology, on energy savings of 518,400 kWh per year,
Vertical roller mill Grit Cone Modification has the of ROI (−30.4%) and CBR value
(0.762) cleaner technology is higher than conventional technology. Energy saving
was 95,900 kWh per year. Vertical roller mill internal modification had a ROI of

Energy savings 120,000 kWh per year. Power Reduction in OPC Portland cement
grinding showed (−67.8%) loss in two technology for Rs. 1 investment and CBR
value is 0.337, energy savings 52,680 kWh per year. Variable frequency drive (VFD)
ROI was loss in two technologies for Rs. 1 investment and CBR value is higher in
cleaner technology 0.564, Energy saving 51,840 kWh per year. False Air Reduction
had the ROI which was loss but cost benefit ratio value is higher in cleaner technology
