2. What is biodiesel?
Biodiesel is diesel fuel made of used cooking oil or oil from seed.

3. How’s It Made? Oil and Methanol make Diesel and Glycerin.
Used Cooking Oil is Free. Methanol is fairly cheap.
Both Diesel and Glycerin have value as commodities.

4. Transesterification 1 molecule triglyceride 3 molecules methanol
3 molecules methyl ester
1 molecule glycerine
100 kg vegetable oil
11 kg Methanol
100 kg methyl ester
11 kg glycerine
