Abstract:

A field-scale demonstration of composting propellants-contaminated sediment was conducted at the Badger Army Ammunition Plant BAAP. Composting, as used at BAAP, is a treatment process in which organic-chemical contaminated soils or sediments are mixed with organic materials such as manure to enhance the role of microbial metabolism in degrading and stabilizing soilsediment contaminants. Sediments contaminated with the propellant nitrocellulose NC were mixed with manure, alfalfa, livestock feed, and wood chips and composted in four static piles. Negative pressure aeration was used to maintain aerobiosis and remove excess heat. Experimental variables investigated during the study were temperature mesophilic, 35 C vs. thermophilic, 55 C, sediment loading 19 to 32 weight percent, and NC loading. Small aliquots of compost approximately 400 cu cm were spiked with pure NC, placed in porous nylon bags and buried in compost piles. These bagged compost samples were used to determine if high levels of NC could be successfully composted. Thermophilic temperatures resulted in the highest percent reduction in NC concentration.
