Encon 8.10% The acrylic sheets have been provided around thecement packers to eliminate the dust emission andincrease the suction intensity of the fan. Henceforthreducing the power consumption by 8-10%. Thisphilosophy was replicated by the supplier andimplemented in new packers supplying theircustomer as an energy efficient system

Encon 10% Earlier our suppliers were using old trucks capacityof 15 ton to supply the raw material (i.e. Cement,coal, slag & lime stone etc.) which were not fuel andcost efficient and were requiring moremaintenance. Now as per our suggestion they havereplaced the old trucks with 25 tons capacity truckswhich are more efficient and cost effective.Therefore leading to reduction in dieselconsumption by 0.1 Ltr/Ton of material, henceforthconserving the natural resources.
