Fossil Fuels are made from plants that were living millions of years ago, the carbon was locked away from the atmosphere. The Carbon in Biodiesel is derived from plants that were living recently. That Carbon was absorbed from the atmosphere & so is not adding any extra.

? So the fossilised fuels created a deficit of carbon until we started burning them again. if so, we are restoring the greenhouse effect and temperatures to what they were many years ago. :?

Oh dear, i should of said nothing at all, as far as i know from the boi diesel forums and info you get on the web it's better for the environment, because it's a natural resoarse and not a fossil fuel or alcohol base fuel, so we are better off, if not then what would be the point of it then, and why all the hipe :?

Me wonders if Nuclear testing and use of atom bombs have more or less effect then driving the family car down the shop. If not stuff it I'm trading in the Rangie. :twisted:

Keep your friends close and your enimies closer :twisted:

None of it will really make any difference until they can stop cows from farting!

Did you know that CFC's were first used in aerosols commercially in 1959, but the hole in the Ozone layer was discovered in 1956! It's got something to do with a couple of volcanoes in Antarctica pumping out CFC's like there's no tomorrow! Hang on a minute... maybe there isn't!!

CFCs do not occur in nature, but some volcanoes do emit large quantities of sulphur compounds that have a similar, but much shorter lived effect. The hole in the ozone layer is probably natural as you say, but its size is not.
As others above have pointed out, all the carbon in fossil fuels is originally from living plants/animals, whereas biodiesel/ethanol is from RECENTLY living plants. This means that biodiesel does not add to the average amount of CO2 in the atmosphere. Diesel produced from plastics is still part of the process of converting fossil carbon to atmospheric carbon, but is environmentally beneficial (to the atmosphere) to the extent that it reduces demand for new oil, and to the environment in general the extent that it reduces the amount of plastic going into landfill, although that plastic probably represents effective long term sequestration of the carbon from the atmosphere, just as effectively (if not more so) as if it were turned into trees.

looking forward to hearing what you think of it Baz. I did some research on Bio a little while back, and the only things that I could find that were negative where potentially a minor increase in consumption and the need to change the filter initially as it clears the muck out of the fuel system. Apart from that it was all good. Better for the environment, its about the only diesel now that passes the lubricity tests which is brilliant for injector longevity, less smoke, works as a solvent to keep the system clean and cheaper than dinodiesel. But its hard to get.

I keen to see the final verdect on bio diesel might even concider giving the rangie a transplant 8O

well apparently,

last time it was checked, the whole in the ozone layer had closed up quite considerably. but the scientists don't know whether it was because of what we are now doing to reduce CO2 emmissions or if it is just a natural cycle!

cheers,
