Georg Dirk: " on my recent journey to South- and East Africa I visited the Soweto Power Station in Johannesburg, South Africa and saw a good example that coal fired power stations can connect in a very positive way with their local community. Citizens can even be proud of their coal fired power station whilst accepting the environmental impact of energy generation."
Increased coal mining and use, pose fly ash waste management and environmental
challenges of fly ash reduction, re-use, recycling and disposal at.Mining offers
a number of fly ash management solutions to coal ash, the solid fossil fuel
combustion residue from coal burning boilers and plants, mainly power stations
and petrochemicals fuel-from-coal plants.
Coal waste includes fly ash, bottom ash, flue gas desulfurisation sludge (FGDS),
fluidised bed combustion waste (FBC), and some by-products like cenospheres
,which are used as a lightweight filler in many products.
South Africa’s energy industry, driven by abundant coal resources, has resulted in generation
of large quantities of coal ash in various forms, mainly from Eskom and Sasol. SA fourth largest
fly ash generator.
About 550 mega ton per year of fly ash is produced by coal power plants around the world
and South Africa is the fourth largest producer of fly ash at 30 Mt per year, after China, USA
and, India.
Fly Ash classification to produce high quality cement replacement materials has a long tradition in
South Africa.
