Thanks Gerry,
Now I know. Believe a lot of palm oil is turned into
soap and is also the basis for a lot of glycerine. I believe quite an amount
could be used for biodiesel locally if the byproduct of glycerine could be
refined and purified properly, thus having the glycerine subsidise the
biodiesel cost. When you are just dumping the glycerine it certainly does
not make sense. The trouble with glycerine is that it is so energy intensive
because the boiling point is 290 C (more than 3.5 times that of ethanol)
B.r., David
