Description

Flue gas is one of the by - products of c oal fired power pla nts that is released into the atmosphere. Fly ash is also another by - product that usually ends up in landfills. Fly ash has been researched as a soil amendment and fertilizer substitute , but has had little success in the past. With a novel method to capture flue gas from the coal combustion process and its intergradation into the fly ash will make the fly ash more nutrient rich, allowing for more microbial growth in soil. Ash was collected from Jim Bridger Power Plant, Point of the Rocks, Wyoming. Preliminary chemical data suggests that flue gas contains various nutrients that are needed for soil microbial growth. Performing growth comparisons based on colony forming units, using a soil control to compare flue gas treated fly ash mixed in the soil against untreated fly ash mixed into the soil, has shown that treated fly ash has the prosperity for application as a fertilizer. Phospholipid fatty analysis is currently being performed to check the lipid content for the three soils to affirm current findings.
