As a user of biodiesel, I am alarmed at the misconceptions that are still flying about.
Firstly biodiesel is normally, in this country, produced from waste vegetable oil that cannot be used for any other purpose, only animal feed and that is only in the case of oil that has not come into contact with meat.
Secondly, palm oil , which is related to rain forest deforestation, is not used for bio diesel in this country, or any country with a similar or lower climate as it gels in moderate to lower temperatures causing problems in engines. No chemical cures this 'plugging' point. It is therefore a very unreliable source for bio diesel.
If you were to try to buy virgin palm oil, you would find it almost impossible in this country. The cost itself makes it totally uneconomical as a fuel, as any other virgin oil, especially with the Government's tax on top on bio fuels.
There seems to to be a notion that the Government is encouraging bio fuel use! The last Government were actually taxing bio diesel manufacturers so heavily most are now out of business!
