[Digestion] slurry from Potassium hydroxide catalyzed glycerin

[Wayne Zschech]

G'day All,

We are looking to use our glycerin byproduct from biodiesel production in
our digester.  The question arises as to the sodium influence on the liquid
slurry.  Does anyone have any experience in this area?  We are thinking
that although potassium hydroxide is more expensive as a catalyst, it will
produce a better quality fertilizer. Does anyone know how this would affect
the end NPK reading of the fertilizer?

Blessings,
Wayne
