European Union is committed to cutting GHG emissions by 20% from 1990 levels by 2020. It has introduced an Emissions Trading Scheme, which started on 1 January 2005, and covers the steel industry. Most of the steel plants in member countries have been allocated a certain amount of CO 2 emissions rights, which will be decreased in the future.
Emissions for manganese and mercury in method 3 are relatively close to the results in method 1, and times the values in method 1, respectively. Beryllium emissions in method 3 are only 4% of estimates in method 1 because a generic emission factor was used. For the four VOC compounds with sourcespecific emission factors, benzene ...
Hard ores, including some copper, gold, iron, and molybdenum ores, may require as much as a moisture ore use lowmoisture ore emission factor for bauxite unless material exhibits obvious If material is stored at multiple points in the plant, the emission factor should be applied to each operation and should apply to the material.
