Cement Energy and Environment

t Around the Plants ~ SHREE CEl\IIENT~:~i\CHIEVES INTE'RNATI()NAL BENCHl\IIARK OF PERFORl\IIANCE I n a recent worldwide review of 90 cement factories and more than 140 kilns, conducted by the International Cement Review and Whitehopleman, UK, Unit No. ll of Shree Cement's Bangur Nagar plant has been adjudged the most energy efficient cement plant in the world as well as the most productive kiln. The data collected for analysing the performance of cement plants in question and generating the performance indexes straddled the following seven aspects : )> Safety )> Manpower producti vity )> Specific output )> Energy efficiency };> Equipment reliability };> Envi ronmental impact };> Product quality The main findings of the analysis are : K esoram Cement, known for its environmental and ecology consciousness, rededicated itself to developing ofgreenery around the plant's limestone mines by celebrating 'Vanamahotsav Saprah' from 17 to 23 August 1999. The celebration was inaugurated by the District Collector Shri Debabratha Kanta who planted the first sapling. Earlier, the plant organised a Tree plantation programme at Sedam on 4th Jul y 1999 which was inaugurated by the President Shri P.K. Goenka, Saplings were presented on the occasion to the villagers for planting.

Line J also ranks highly in terms of electrical energy efficiency. Both kilns operate under high specific loading and kiln 2 is the most productive kiln ; in the survey with reference to tonftes-per-day per-cubic meter of internal volume. Burning zone loading are also high as a result of this high specific loading on the kiln., yet refrac tory consumption is not adversely affected. C0 2 emissions from the kilns are low as a consequence of the low thermal energy consumption; however dust emissions are only in the middle of the performance rankings. The major area for potential improvement of the ki lns is in the reliability of operation. Both suffer a high number of stops and consequently the mean time between stops is well below the median of performance. The safety record of the factory is good. The factory has a large number of people employed, resulting in low overall productivity. Shri Debabratha Kania planting a sapling. Senior President Shri K. C. Jain is at left. 9
