Fly Ash has a great capacity for agricultural usage. Its mineral characteristics can improve soil health and harvest properties. By mixing soil with up to 50 fly ash, the texture density and water capacity can be enhanced as well as acidity or alkalinity, due to the hydroxide and carbonate salts found in fly ash. This will also provide crops with sufficient nutrition.

The harvesting and subsequent beneficiation of disposed ash has the potential to be a consistent supply of quality ash more than 500 U.S. coal-fired plants have closed since 2010. The delivered cost of this quality fly ash will likely exceed 50ton.
Total project cost of such plant including cost of coal washery and AFBC for using washery rejects at ash content at 42, 34, 24 is likely to be cheaper by 5, 8 and 10 respectively. Generation of 15 to 18 MWe by AFBC is an extra benefit. Larger gains may be expected if life-time cost in lieu of lower RampM is taken in to account.
