POWER PLANT FLY ASH TO N-FERTILIZER
UEE has developed an innovative manufacturing technology for high
efficiency, low cost nitrogen fertilizer from fly ash, which is a recycled
material from coal power plants that may contain high concentrations
of carbon.
Traditional N-fertilizer production uses natural gas as the primary
feedstock. The high natural gas price forced nearly 40 percent of the
industry N-fertilizer capacity to permanently close between 1999 and
2005. Consequently, the US relies on imports for nearly 45 percent of
its N-fertilizer supplies. The traditional N-fertilizers are water-soluble
compounds, resulting in significant loss of fertilizer and pollution of
streams and ground water. At the same time, America coal power
plants produce more than 76.5 million tons of fly ash per year, and
most of it is disposed of in landfills. UEE has developed a patent
pending process for converting the fly ash to high efficiency water
insoluble nitrogen fertilizer. This technology has been licensed to a
major energy company in October of 2007.
Stage of Development
- Stage III: further development and customer testing
- Patent application filed
- Funded by NSF and NYSERDA
