Project Description

 

 

Project Description:

This project investigates methods by which fly ash is stabilized into conglomerates that could be used as road construction or fill material and by which microbial processes can be applied to produce various carbonates by iron-reducing  bacteria.  Carbonates are produced in situ; at the surface by photosynthetic algae and at depth by anaerobic carbonate producing bacteria.  Microbial activities would convert CO2 into a stable mineral; waste ash would be converted to a useful product; leaching of heavy metals from fly ash ponds would be reduced/avoided; and other applications of this technology in agriculture or food processing are possible.

Description: This is an ongoing,  long-term project.  Results obtained so far indicate that siderite and calcite precipitation using metal-rich fly ash lime is generally associated with the bacterial metabolism of organic matter and hydrogen coupled with microbial Fe(III) reduction in the presence of reducing environments and high bicarbonate buffer or a H2/CO2 atmosphere. High alkalinity and Fe(II) ions, as prompted by bacterial activity, seem important to biologically facilitated precipitation of carbonate minerals such as calcite and siderite. The microbial production of Fe(II) and lowered redox potential (Eh) also stimulates siderite precipitation.

Eight scientific publications/presentations are in review or have been given.  One patent application has been submitted.
