The goal of this project is to test the feasibility of stabilizing coal slurry solids (CSS) wastes by directly seeding plants into the waste. This is not done conventionally because the waste can generate toxic amounts of sulfuric acid. The approach is to neutralize the potential acidity by mixing fluidized bed combustion (FBC) waste into the slurry. If successful, this approach would both help dispose of FBC wastes while providing a more economical slurry stabilization technique. The project involves growing forage plants in CSS-FBC mixtures in the greenhouse. In the first two quarters the authors designed the experiment, secured greenhouse space, purchased the seeds, collected, dried, analyzed the FBC and CSS samples. The samples represent a typical range of properties. They retrieved two FBC and two CSS samples. One CSS sample had a relatively high CaCO{sub 3} content relative to the pyrite content and required no FBC to neutralize the potential acidity. The other CSS sample required from 4.2 to 2.7% FBC material to neutralize its potential acidity. This report covers the third quarter of the project. The authors produced the CSS-FBC mixtures, analyzed the soil fertility parameters of the mixtures,, planted the crops, and monitored their growth. All mixtures support at least some plant growth, although some plants did better than others. It is too early to analyze the results statistically. Next quarter the plants will be harvested, yields calculated, mineral uptake evaluated, and a final report will be written on plant response to CSS-FBC mixtures.
