The reason for this is of course that ethanol is a great cosolvent that keeps glycerine droplets from settling, and soap along with them. I had no way to test the glycerine content but I'm pretty sure it'll be abnormally high.

Has anybody tried centrifuging out the suspended glycerin proir to a drywash?

I'm looking into going with ethanol instead of methanol because I was doing a little research and the VOC's released into the air with the methanol are huge compared to ethanol and could get expensive on commercial scale with the new 'Cap and Trades' coming down the pipeline. Besides, whats the point of making biodiesel with methanol if your going to become a gross polluter in the manufacturing process and harm the environment anyway?
