What to do with your glycerin layer
What is the glycerin layer (aka “glycerin“)?
Glycerin is the byproduct left over after the biodiesel reaction process is complete.At the end of the two-step reaction process, there will be 50 gallons of biodiesel in the main tank resting above 10-12 gallons of glycerin. (This will be 100 gallons of biodiesel atop 20-24 gallons of glycerin).
This glycerin is usually dark brown and has a thicker viscosity than reacted biodiesel which is usually a honey brown color. Before moving to the wash cycle, your glycerin must be drained out of the tank at the ball valve and captured in a separate container.
WHAT DO I DO WITH MY GLYCERIN?
There are many options.
1. Put it in demethylating equipment. This will remove the methanol from the glycerin and leave you with a quickly cooling block of glycerin soap. The soap can be further refined or thrown away. The methanol is approximately 90% pure and, with a little further refining.
2. Put your glycerin and your wash water into the equipment
3. Make soap.
4. Feed your glycerol to cattle.
5. Take it to a sewage treatment plant where they have an “anaroebic digester”. THough they probably won’t pay you for it, they do welcome the stuff.
6. Use it as a composting agent.
7. Use it as a dust suppressant.
8. Burn it.
NOTE: There are things you should NOT do with your Glycerin. Remember, you should never dump it into a stream or down the drain. Glycerin will kill fish and other aqautic creatures due to its high BOD (Biological Oxygen Demand) rate.Related
