True, China is a big market. There is also like you mention India, USA, Europe, etc. Total accumulated fly ash worldwide is most probably even bigger than Red Mud. 2.5 B ton in China alone...
"At present in India, about 120 coal based thermal power
plants are producing about 112 million tons of flyash every
year. With the increase in demand of power energy and coal
being the major source of energy, more and more thermal
power plants are expected to be commissioned in near future.
As per the estimates, flyash generation is expected to
increase to about 170 million tons by 2012 and 225 million
tons by 2017 ."
ACH GENERATION & UTILIZATION DURING 1st HALF OF THE YEAR 2011-12
Nos. of Coal/ Lignite based : 90 nos.
Installed capacity : 83797 MW
Total Ash generated : 66.49 Million-tonne
Total Ash utilized : 36.26 Million-tonne
Percentage Utilization : 54.53%
"Present production rate of fly ash
In the United States about 131 million tons of fly ash are produced annually by 460 coal-fired power plants. A 2008 industry survey estimated that 43% of this ash is re-used."
China (2006 data)
"Coal burning electrical power is a major power supplier in China. The produxtion of coal is 2400 million tons in 2006, and more than half was used for the fuel of power stations.
The production of flyash (including bottom ash) is 300 million tons and the accumulative amount of flyash exceeded 2500 million tons."
Europe (2001 data, quite old data but gives some idea):
Coal Combustion Products (CCPs) are produced by coal combustion processes in power plants which burn either coal or lignite. The CCPs include combustion products such as boiler s lag, botom ash and fly ash from different types of boilers as well as desulphurisation products such as semi dry absorption product (SDA-product) and flue gas desulphurisation gypsum (FGD gypsum).
In the European Union (EU 15) approximately 60 million tonnes of CCPs were produced in 2001. Around 88 % of the CCPs were utilised in the building industry, for construction work in underground coal mining as well as for recultivation and restoration purposes in open cast mining. Applications for CCPs include their use as an addition to concrete and as constituent of and raw material for cement. Furthermore they are used as aggregates or binder in road construction, as mineral fillers and as fertilisers. Where necessary, CCPs meet relevant national and European building materials standards and regulations.

Excelllent work, Alumina1!
Yes, I agree with you that Flyach could be a HUGE business! IF the Chinese don't "copy" this (and I don't think they can), they might be FORCED to use it in view of the l levels in their major cities. We are talking beijing ... I mean this city alone has huge problems as the coal plants spew the particles up in the air. Sure, there are other sources of pollution (cars/trucks/bikes, sand storms,...), but ORT. tech. could significantly reduce the pollution levels. Do the Chinese know about this technology? How would Ort let them know? Would they lobby the government? India is another great market for this. If they help with the mud, then it would be an easy ... other service that they could provide and market that they could acquire! But, I agree with you, it is hard to know how significant that would be $-wise!
