WASTE & RECYCLING
COAL ASH
reuse
T
here are myriad uses for coal ash – a key by-product from thermal power generation – which range from cement blending, cement-less concrete production, brickmaking and road stabilisation, to plastic additives, agricultural uses and neutralising acid mine drainage. “Our country is running out of space to dump the millions of tonnes of coal ash produced annually and it is imperative that we support all attempts to take useable ash out of the waste stream at its source,” says Belinda Heichler, director, South African Coal Ash Association (SACAA). “It is also worth noting that the requirement for fly ash has grown over the past 30 years, but that the number of off-takers has not,” she continues.
Facilitating role Heichler says SACAA has an important role to play, particularly in promoting the use of coal ash more widely and to a more diverse audience than before. “In a depressed economy, it is safe to say that SACAA will do everything within its abilities to help individuals, companies and government departments unpack the characteristics of different types and grades of coal ash, and to assist in the use and commercialisation of products derived from this valuable material,” Heichler concludes.
Coal ash has a wide range of applications as a low-cost raw material
