Ha!
Checked it out. Methanol is consumed making biodiesel from oils, not produced from them.
I had a friend who made his own biodiesel from used cooking oil. I believe he added glycerin to the oil which is interesting because I believe waste fats give up glycerin, thus why they were recycled during the war, the glycerin being used in explosives manufacturing. It appears they add alcohol to get the chemistry, so a ready supply of "cheap" industrial alcohol supports a biodiesel manufacture?
