I have 600 gallons of glycerin to dispose of and I need to dispose of it soon and quickly. Its too much to make into soap.

I live in the country, so I could mix it 50:50 with water and spray it on the gravel roads. I've heard that trying to burn it is a problem.

What is the easiest way to dispose of this quantity???

Thanks.

Two questions:

Where are you located?

Glycrin from KOH or NaOH based biodiesel? Or both?

Todd, two answers:

I live in southwest Iowa.

Mostly NaOH some KOH, but I don't know which is which now. I suppose I should be able to tell by the consistency. It is a year old. Most of it also has methanol in it.

I have been able to dump mine in a manure lagoon at a dairy farm. the lagoon holds 1,000,000 gal. of manure. The glycerin is biodegradable and is a spit in the ocean of manure.

If you have any paper plants nearby maybe they'd be interested in using it to fire their boilers in conjunction with the other junk they use.

Another avenue is paving companies; they use diesels fuel to coat the beds of the dump trucks and also to dip their instruments in so the asphalt won't stick. Some have tested glycerine as a substitute with good success. Methanol must still be in it on both counts. Cut 50/50 it does the job from what I've read.

No manure lagoons anywhere near that large.

No paper plants.

Now what?

If you can transport to Kansas I can dispose of it with my crude glycerin when I have a full tanker worth on hand.

Next on the list would be water treatment plants; the bugs love the methanol ladden glyc and apparently it helps them do a better job of breaking down the sewage.

If you get up to WI I will take it. We can burn it in our furnace.

Since this glycerin is over a year old, is it too old to make soap out of some of it?

How long will glycerin keep for soap making???

dmax,
It should still be good to make soap from. Unlink oil the glycerin and soaps should not go rancid. Especially if the methanol is still in the glycerin. If your biodiesel from the glycerin was fully reacted there should not be any oils left in the glycerin.

It should still make some fine soap! Use your KOH for liquid and your NaOH for bars.

Dmax--

How is the 600 gallons stored? Totes, cubies, barrells? Exactly where in Iowa, I am in Lincoln, NE. Reply by PM if you do not want to advertise your locale.

Norman,
Right now its stored in 55 gallon barrels that are nearly full. I have 275 gallon totes and could easily transfer to totes.
I live about 25 miles east of Hamburg.

The totes might work best, we could set them on the trailer and then pump the glyc over? I do not know WTF I will do with another 600 gallons of glycerin, but it would give me plenty of feedstock for my methanol recovery system testing. I do have room to styore it and a forklift to move it around with.

I had the same problem with the glycerin buildup, I read up on burning it and made a couple of small burners that worked. This stuff will burn hot as heck under the right conditions. I built a large burner out of an old hot water heater and jacketed it with a 55 gallon drum. I start the fire with a little biodiesel and then start the glycerin feed. The fire in the hotwater heater heats the water in the 55 gallon drum and the water from the 55 gallond drum feeds my hotwater tank in the barn. I heat 150 gallon of water to 170f in about 2 hrs then I use the hot water to de water one tank of oil and heat another tank for processing. The only problem I have is that I make 50 gallon batches and produce 10 gallons of glycerin each time, it only takes 5 gallons of glycerin to heat the water for processing. I think I will build another one this winter to heat the house.
