This is actually a great effort you have put into this and it is really educative. But i have question here:

Another issue of concern about the usage of crude oil is that it causes environmental pollution and produces pollutant such as carbon dioxide, sulfur dioxide and other particulate matters.

I totally agree that the burning of fossils results in the production of harmful products. But are you saying methyl ester (biodiesel) will combust without producing CO₂?
