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?
Due to high cetane rating of biodiesel, it produces lower CO2 up to 60% lesser than petroleum diesel. Therefore it produces CO2 when it burns too but to lower extent compared to petrol-diesel
Interesting... Thanks for the clarification. Perhaps the word "more" could have made my question unnecessary.
Best wishes!
