ArcelorMittal South Africa
Annual Report 2010
We continue to invest in the following
ongoing projects to reduce air emissions:
Vanderbijlpark Works
• Sinter plant off-gas treatment
project: this project, which is
expected to reduce SO 2
emissions
by 1 500 tonnes per annum and
particulate emissions by 1 000 tonnes
per annum, is on track for completion
in quarter one of 2011. (reduction
figures based on full production).
• EAF dust extraction system: after
the temporary halt reported in
2009, this project is now back on
line. Detailed design is underway
and we expect construction
to be completed by 2013/14.
Once commissioned, this system
is expected to reduce visible air
emissions to a similar extent as
the system currently running at
Vereeniging Works.
• Blast Furnace D stockhouse
baghouse project: this remains on
track for completion by 2012.
• Implementation of various
improvements at the coke batteries
[as per requirements of the National
Environmental Management:
Air Quality Management Act
(NEMEQA)] over the next
five years.
Newcastle Works
• Blast furnace cast house dust
extraction unit improvements: on
track for completion in 2014.
• Desulphurisation facility at steel
meltshop: on track for completion
during May 2011.
• Implementation of various
improvements at the coke batteries
(as per NEMAQA requirements)
over the next five years.
Coke and Chemicals
The coke battery at the old Pretoria
Works is scheduled for a complete
upgrade in order to comply with the
new NEMAQA requirements over the
next 5 years.
CO 2
emissions and their
impact on climate change
CO 2
emissions are a further important
air emissions indicator but, because
of the fact that they are inextricably
linked with issues of energy usage and
climate change, they are dealt with
separately in the chapter on energy
and climate change.
Water usage and pollution
While iron- and steel making requires
large quantities of water, we are
making good progress in reducing
water consumption, with a 37%
absolute reduction being achieved to
date from the baseline of 2005. We
stick firmly to our goal of reducing
water intake by 40% against this
baseline. However, delays on the
project to make Newcastle Works
a ZED facility has necessitated an
extension of the target date from
2011 to 2013 (for more detail view
the project list that follows).
Our total freshwater intake for 2010
was 3.64kl/tonne of liquid-steel
produced which was up on the 3.36kl
of the previous year, due mainly
to increased water usage at our
Vanderbijlpark Works where significant
water quantities had to be used for
rehabilitation projects.
Each production facility draws its
water from a particular source.
Vanderbijlpark Works draws its water
from the Vaal River and Vaal Dam,
Newcastle Works from the Ngagane
River, Saldanha Works from the
municipality and Vereeniging Works
from the Vaal and Klip rivers. The total
water withdrawal per plant is outlined
in the graph below.
