Abstract

This paper reports on work done by Dravo Lime Co. in the Dravo Corporation Research Facilities with the cooperation of the U.S. Environmental Protection Agency, Project R803999-01-0. The primary purpose of this study has been to combine flue gas desulfurization (FGD) sludges with municipal waste to produce fertile soils. A second objective has been to stabilize and combine coal fine refuse with municipal waste to identify potential stabilization and revegetation techniques. Testing on the FGD municipal waste mixtures has included seedings both under greenhouse conditions and in outdoor test plots. Coal fine refuse-municipal waste sludge mixtures have also been successfully stabilized and have been successfully seeded and tested under greenhouse conditions. Plant varieties that have been growth in these combined waste products include corn, soybeans, oats, ryegrass, and crown vetch.
