Waste Management in Some Medium Sized Metallurgical Industries

Panda, S C and Ray, H S (1996) Waste Management in Some Medium Sized Metallurgical Industries. In: UNSPECIFIED.



In thispaper, an attempt has been made to discuss some aspects of the nature of wastes generated and their management in some medium sized metallurgical industries, viz. mini steel plants of (1) MIs Special Steels Limtited, Bombay; (2)MIs Sun Flag Iron and Steel Company Ltd., Bhandara Road; (3) MIs IPISTEEL,Dhenkanal; (4) MlsIncast Metal Private Limited, Bhubaneswar (Steel Casting); (5) MIs Indo Flo gates Limited, Kalunga (Refractory Castings); (6) MIs Konark Malleables Private Limited, Jagatpur (Processing of Malleables) and (7) Mr's Foundry Forge Plant, Ranchi (Forging). The wastes considered are solid, liquid and gaseous entities. The solid wastes are in the form of slag, mill scale, used refractory, used moulding sand, coal ash, saw dust, metal turnings and borings, various dusts from flue gases and dry grinding units, lime slurry and sludges. The liquid wastes are in the form of industrial effluents at ambient and higher temperatures. The characteristics such as pfl, total suspended solids, total dissolved solids,dissolved oxygen, chemical oxygen and biological oxygen demands, oil and greases etc. are given quantitatively. The gaseous wastes consists of flue gases and fumes from furnaces and tar pots. These wastes may contain oxides of carbon, sulphur and nitrogen, cyanides, fluorides, etc. Values of these characteristics are given. Mention has been made of the requirements of the Central Pollution Control Board (CPCB)for the Iron and Steel Industry together with pollution control measures for better environmental management.
