Composting coal ash with poultry litter for topsoil manufacture

This paper describes the progress of studies using coal ash mixed with organic byproducts in a compost process as a means of converting ash to a desirable commercial product. Mixtures of fly and bottom ash, broiler chicken litter manure, sawdust and pine bark were successfully composted during the winter of 1994. The recipes and compost procedures for production of the manufactured soils are described. The physical, biological and chemical properties of the manufactured soils are being studied and the initial results presented.
