I make about 15-20 gallons of glycerin a week (KOH) and need an efficient way to dispose of it. I use the glycerin to pre-treat with, so the methanol should be gone. Initially I had a guy who was taking it and using it to heat his raw oil to run a large processor he was trying to get into commercial production. He has folded and I have been burning it off in a barrel and composting some in a horse manure pile, but this is too slow.
So, I have two questions:
1. How do you guys dispose of your glycerin?
2. Is it possible a small septic tank system would work?
I have heard some sewage plants say it enhances their processing, but I don't have the contacts to make that work. The only thought I had was to process it into liquid soap and sell/give it away to mechanics as a degreaser.
