OK, so my education continues. Magnesol, according to the manufacturer is synthetic magnesium silicate. So it is a magnesium compound. Essentially magnesium chemically combined with sand.

I also now understand that amost all of the methanol is cooked out of the glycerine as well as out of the bio. The glycerine is the base material for making soap.

HOWEVER, methanol is so poisonous that even trace amounts of it are harmful if injested or absorbed through the skin. So I don't understand how soap and magnesium sand can be safely fed to livestock - especially if they contain even the slightest traces of methanol and/or lye. I'm hoping Fabman can answer that one for me 'cause right now it doesn't seem to make sense to me.

Right now, the concerns over the wastes are really the only thing standing in the way of my moving forward with setting up my own bio processor.

One other question. Is there any alternative to using methanol? Any other less-hazardous, kind of alcohol that can be substituted for the methanol?
