Coal Combustion Products (CCPs)
The generic term used to describe all residues emanating from the combustion of coal
THE VARIETY OF CCPs DEPEND UPON:
- Combustion technology (pulverised coal, fluidised bed, etc)
- Collection technology (bagfilters, electrostatic precipitators)
- Treatment of flue gases prior to release (desulphurisation, ammoniation, etc)
ENVIRONMENTAL BENEFITS:
Significant environmental benefits accrue when CCPs are used:
Given South Africa’s abundant coal resources, large quantities of CCPs are produced both in the generation of electricity (ESKOM) and the production of liquid fuel (SASOL).
- For every ton used to replace cement, the release to the atmosphere of one ton of carbon dioxide, a greenhouse gas, is avoided
- Incorporation in soil to improve fertility pasteurisation of sewage sludge
- Immobilisation of toxic elements Counteracting acid mine drainage
- Rehabilitation of minespoil and slimes dams
- Backfilling of mines to prevent subsidence
