was 54340 kWh per year electricity was saved.In controlling Air pollution (Double
stage Electrostatic precipitator) is used return on investment was −1.0303% for Rs.
1 investment and energy savings is 11,000 kWh per year with Rs. 0.5225 lakh per
year and cost-benefit ratio value is 0.01837 still in air pollution control conventional
technology is used. Caustic soda processing return on investment was (-65.31%) for
Rs. 1 investment and cost-benefit ratio value is 0.358 gave a benefit of Rs. 3.0875 lakh
per year. Sugar industry has been recycling Lime grits is 810 tons per year, Boiler
Ash and coal ash 3900.6 Tons per year were reused in cement manufacturing and the
benefit-cost is Rs. 123 lakh per annum. Coal ash was produced 5400 Tons per year
and the benefit-cost is Rs. 140 lakh per annum wherein coal ash would be sold out to
brick manufacture industry to be used as raw material. Belt conveyor, Control adsorption Cost savings was Rs. 0.07 lakh per annum. Dust collector collects the dust in
the Hooper, Pan Hooper controls adsorption in process itself, Sprinklers Controls air
adsorption. Green Belt was created where about 8522 trees were planted and cost for
the plantation was Rs. 5 lakhs. The trees planted were Coconut Plantain, Teak, Palm,
Ashoka, Neem, Sobibul, Casurina and Pungan which act as natural bio-remediation
to control air pollution. Rain water harvesting was adopted for recharging ground
water. Recycling of molasses around 18,000 tonnes sent to cattle fodder, field, Oil
mills and distillery industry with a profit of Rs. 446 lakh per year. Press mud was
added with ETP sludge to make bio-compost about 42 tons per year, Sludge thickener used in Bio-compost earned a profit of Rs. 31,000 per year. Cane cutting (ROI)
return of investment was 2.0876% and cost-benefit ratio value is 0.3433 leading to
a profit of Rs. 6000 per month.
