This project demonstrated that staged combustion in a conventional fluidized bed boiler can be used to recover fractions of phosphorous and potassium in forms that can be used in the existing feed and fertilizer industries. Swine manure was dewatered and blended with turkey litter prior to burning in a bubbling fluidized bed. Combustion conditions were optimized for blends of swine solids and turkey litter in a commercial pilot facility. Recommendations are made for combustion of the blended fuels. Ash was granulated for tests in the fertilizer industry.

This paper reports on a project that compares the economics of major technologies and practices under development for CO2 sequestration, including captured CO2 storage options, such as active oil reservoirs, depleted oil and gas reservoirs, deep aquifers, coal beds, and oceans, as well as the enhancement of biological sinks such as forests and croplands. An international group of experts has been assembled to compare on a consistent basis the economics of this diverse array of CO2 sequestration options. A summary of the results is being prepared along with a spreadsheet model to facilitate economic comparisons. The primary funding source for the project is the Department of Energy (DOE); and the Tennessee Valley Authority (TVA) and the Electric Power R...

This study was conducted to evaluate the influence of various waste products on the growth of trees. Two sites, one in northeast Alabama growing sycamore (Platanus occidentalis L.) and the other in west Tennessee growing cottonwood (Populus deltoides Bartr. ex Marsh.), were studied. At the Alabama site, 3 yr of replicated field plots were evaluated to assess the influence of scrubber gypsum, wood ash, and containerboard sludge on the growth of sycamore on a Decatur soil. Compared to the control treatment, a mulch application of scrubber gypsum at a rate of 672 Mg/ha improved the volume response of sycamore after 3 yr. There was no volume response to liming, whether agricultural lime or wood ash was used, and sycamore did not respond to nitrogen (N) in the containerboard sludge treatment. Further investigations into the use of scrubber gypsum applied at high rates as a mulch in combination with weed control appear warranted...
