[USCC] Using alkaline stabilized N-Viro in compost

[Craig Coker]

Maureen:

I believe it would.  Previous attempts to compost alkaline-stabilized
biosolids have been complicated by the high pH (if it kills pathogens, it
kills beneficial microorganisms) and by the high levels of volatilized
ammonia.

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?
