PPC Riebeeck West: Storm water Management Plan Page 27
1.6.7 Plant upgrade project:
With the changes in environmental legislation concerning emissions, PPC will be required to
upgrade / replace equipment at PPC Riebeeck to remain compliant when the new regulations
(and the associated minimum emission standards) come into effect.
The existing plant infrastructure lends itself to a combination of upgrading and replacement of
equipment cost effectively, while maximising the use of the current plant infrastructure and
equipment. Accordingly old equipment would be replaced to ensure process efficiency and
associated compliance with legislated air quality standards. The upgrade would also allow for
optimising energy and raw material use efficiency. PPC subsequently appointed an
environmental consulting company to undertake the requisite authorisation processes required
for the proposed PPC Riebeeck upgrade project. What PPC is proposing:
Upgrade certain sections of the existing PPC Riebeeck cement manufacturing plant with the
view to increase the clinker production capacity from the current 570 Kiloton/annum to 800
Kilotton/annum via:
Replacing the existing two kilns with one new kiln line;
Decommissioning and removing the two existing kilns;
Upgrading the existing raw milling facility to accommodate the increased production rate;
Installing a new coal mill for indirect firing and inert operations;
Upgrading the existing cement milling facility to increase the current capacity to
accommodate the increased production rate;
Converting each mill to a closed circuit operation via the installation of a high efficiency
separator;
Upgrading existing conveying equipment to meet the increased production rates; and the
Installation of emission abatement technology to improve air quality.
No changes are proposed for other on-site operations, however additional on-site storage would
be required for fly ash and slag which will be used in the process as raw materials.
