The age old problem for us larger-batch bio guys.

We pull ~12 gallons of gly out of every 50 gallon batch we make. Do that 2-3 times a week and you've got darn near a couple of large drums of glycerin sitting around.

We've been taking ours to a local larger bio retailer who takes it for a charge of 20cents/gal, or roughly $10 a barrel.

But it's not so much the cost as the hassle of getting it over there.

So, although I know this topic has been around the block in the past, I just wanted to get some thoughts from the folks who are producing large quantities of glycerin.

Thanks!

Living on a ranch has it's benefits! I use all the glycerol I make. After recovering the MeOH I mix the glycerol 50-50 with water and use it as a dust suppressant on our gravel roads. I also mix it with water and spread it on my fields as a supplemental fertilizer. Last year I made a ton of fuel pellets using 10 percent glycerol mixed with 90 percent waste straw. The fuel pellets worked great, but I found out they burn way to hot for a pellet stove! I'm looking for a "corn" stove to try, they have a heaver fire-box that should last longer..............

 

I just got about 2 galons of it out of a small batch and was wondering what I needed to use it as fertilizer for the rose bushes. Can I just add water to it and use it that way? I don't want to kill my plants but I've heard you can use it that way.

 

that just depends on the kind of lye you are using.

Since we switched to NaOH, we have been using it all as a weed killer. that is saving us $$$ not buying roundup and getting it out of our way. 2 birds w/ 1 stone- and cheap fuel.
