<strong>ArcelorMittal</strong> <strong>South</strong> <strong>Africa</strong><br />

Annual Report 2010<br />

Environmental performance continued<br />

SO 2<br />

emissions have dropped significantly when compared<br />

with 2009 figures, from 3.26kg/tonne of crude steel to<br />

2.66kg/tonne of crude steel – an 18% improvement.<br />

but rather to the fact that monitoring<br />

systems were expanded and<br />

improved. The Vereeniging Works EAF<br />

dust extraction system is working<br />

well. There are no visible emissions<br />

escaping through the roof and the<br />

dust capture rate from the meltshop<br />

activities has improved by 45% to the<br />

current 16.84kg/tonne of liquid steel,<br />

which can be regarded as an optimum<br />

of what can be achieved. Improved<br />

maintenance of coke batteries and<br />

dust extraction systems and greater<br />

vigilance have also helped to lower<br />

visible particulate emissions. Monthly<br />

reporting highlights any potential<br />

problems and we have focused on<br />

improving our response time for<br />

rectifying such issues. The coke<br />

batteries ceramic welding project,<br />

completed last year, has also helped to<br />

reduce particulate emissions.<br />

at this operation by 46% during the<br />

year under review in specific terms<br />

– a significant achievement. There<br />

was a fairly significant increase in the<br />

emissions from our Newcastle Works<br />

facility, which can be attributed to<br />

improved monitoring and problems<br />

experienced with the sulphur<br />

The increase in specific SO 2<br />

emissions from our Saldanha Works<br />

facility can also be attributed to<br />

improved monitoring and the higher<br />

utilisation of the coal-based Corex<br />

furnace to produce liquid iron.<br />

group as a whole. The Vanderbijlpark<br />

Works coke clean-gas project,<br />

R327 million, was commissioned<br />

during the year and has played a<br />

pivotal role in reducing SO 2<br />

emissions<br />
