by product disposal

[powerstrokin it]

I am starting up my home brewing Bio-Diesel. I was wondering what do you do with your by-product, your method of disposal.

I gravity drain into a 275 gallon tote just outside my shed. The tote is buried about half the depth of the tote so it is lower than the drain pipe. Once the tote is full, I pull an empty tote onto my little trailer, pull the trailer beside the buried tote, and use a boat bilge pump to pump the contents of the buried tote into the trailer tote. I then haul that to the city wastewater treatment plant where they let me dump.

I put it in the compost pile or if I have a good amount ,20 gals or more, I'll fire up the biodiesel burning backhoe and bury it.

as long as the methonal is removed, the gly is biodegradable and fairly safe. I use some of it to spray on my driveway and parkinglot to keep down dust and I have a burner rigged up with a furnace nozzle and a air comp to burn some of it to help heat my WVO supply tank. however burning glyceren is very dangerous, you must burn it at at least 1200-1300 degrees or it produces a highly poisoness gas not that much differant than mustard gas. I have a link to a artical on this let me find it.

here is the link on the poison gas from burning glyceren
Acrolein - Wikipedia, the free encyclopedia

also another trick that I found with glyceren is to use some of it to kind of "jumpstart" your reaction before you add your methoxide to the batch. I add about 10 gallons to 50 gallons of realy bad or wet oil and let it turn in the processor for about 30 minutes then let it settle out and drain it off. this will get rid of a lot of the water in the oil and will drop the titration a couple of points. use fresh glycerol that still has the leftover methonal in it, try it it realy works.
