Field Measurements of Stack Emissions in Progress

 

 

 

 

·             Global warming – NCB studied measures for reduction of green house gases  (GHG). Measures adopted by International cement industry has been documented and quantum of energy saved in terms of thermal and electrical power has been taken into consideration. Various measures adopted by the Indian cement industry reduction in thermal energy achieved resulting lower emissions of green house gases have been studied in details. The concept of Clean Development Mechanism (CDM) ultimately provides the economic benefits to the industry.


 

·             Utilization of Hazardous Wastes – NCB studied physico-chemico-mechanical characteristics of various derived fuels (WDF) like Shredded tyres, ETP Sludge, Plastic waste etc. for use as secondary fuel and recommended technological measures. Trial runs of some WDF in cement plants have been carried out.
