I have a dairy farmer just up the road from me and I am going to ask him if he wants my NaOH demethed glycerin that I am currently, mostly, just putting in the landfill which I feel is a waste.
With my new setup I will be producing around 55 gallons plus of the stuff per batch, I figure I could just mix it with water into a tote as I drain it so he can pump or pour it if he decides he wants it...
I am just not sure what I should suggest for the best use of it, manure lagoon or feed for the milkers? What would you farmers on here suggest? If you think its better as a feed I will print off that report on feeding it to livestock, if you think its better to just dump it in the lagoon to feed the bugs I wont bother...
And off topic;
I have read that NaOH glycerin is no good to use in the garden composter, I have not been able to find out why, does anybody know what the problem is with NaOH glycerin and gardens?
Biodiesel glycerin for ruminants :
Composting the glycerin is best when the catalyst is KOH as potassium is a nutrient whereas sodium could actually kill the plant. If you water wash you can use the first wash water as a good weed killer if you process using NaOH.

more links on feeding glycerin to ruminants.
The Composting bacteria require a slightly acidic environment.
...and the excess sodium is usually a problem. Plants and composting bacteria can use potassium or calcium, but sodium... not so much.
I am going to go talk to the guy this week...
Nice compilation of links!
When you say
Can you recall which study you have listed there that has that stated?
Why I ask is the German study linked to by LE above fed the cattle glycerin with up to 27% methanol with no ill affects (at a maximum of 10% glycerin/feed) Also I recall reading somewhere that the methanol is not toxic to ruminants due to a missing protein in their blood or something like that...
Never mind, its in the first paragraph of the first study in the links. The 150PPM limit is only in USA it appears. If anybody knows of any Canadian regulations I would be interested, obviously.
