[USCC] Using alkaline stabilized N-Viro in compost

[dmhill@aol.com]

 Maureen:
Composting high pH? organics, including lime stabilized biosolids comes with its own unique set of challenges. The biosolids composted at WSSC's Site II were lime stabilized prior to composting. The composting process worked well however, an inordinate amount of money was spent on odor control management practices and technology.

I am wondering why someone would duplicate a Class A process by composting finished N-Viro product? Is it possible that the the N-Viro product will be blended with the finished compost, thereby enhancing the overall nutrient value, adding lime and mitigating odor associated with the N-Viro product?

I just heard of a plan to use sewage sludge (dried Class A sewage sludge 
that has been mixed 50-50 with cement kiln dust) in a composting operation.

Would the high alkaline material (pH 11 or 12) be a problem in the active 
compost?
