A Technique Called N-Viro Soil Remineralization Using Sewage Sludge Mixed with Cement Kiln Dust
Roughly 140 billion pounds of sewage sludge are produced annually in the U.S. in an attempt to separate our human wastes from the waters we mix them with. This number has steadily increased over the last two decades as more stringent waste water treatment regulations have been put into effect. Standard methods for dealing with sludge have included incineration, ocean dumping, landfilling, land application on farms and composting.
