Posted By: Nick ParsonsAnd you say ''it sends up just as much CO2 ''
Posted By: Nick ParsonsFT, you say: ''.... instant-add of CO2 from biofuel'' . Surely ''instant-add of CO2 from 'anyfuel' ''
Posted By: SeretAnything which replaces geologically sequestered carbon with carbon that's already cycling is a net win.
Posted By: SteamyTeaDoes anyone know how much energy it takes to convert old chip fat to bio-diesel?
Posted By: jamesingramdoes anyone know if there are other uses for 'recycled veg oil' that dont involve burning it
Posted By: Peter_in_HungaryDo you mean 'chip fat' or old cooking oil?
Posted By: SeretST: don't know about the embodied energy exactly, but normal refining is pretty intensive, and I know a company up in London who run their operation from a railway arch, so it can't be too hardcore.

Posted By: rangichangisamHi- Don't anyone kid themselves that running on used veg oil is more sustainable than diesel.I run on used veg oil- the reason? - its cheaper.Why is is it not more sustainable than diesel you may ask, answer... because pretty much ALL used veg oil ends up in the diesel supply anyway. Say you fill up with 50 litres of diesel, guaranteed that at least half a litre of that is veg oil, more in other countries. By running on pure used veg oil or biodiesel all you are doing is burning veg oil that otherwise would have been burnt in any case. The veg oil that doesn't enter the diesel supply generally ends up being sprayed on to coal to add to its calorific value before it gets burnt in power stations.I guess there is some merit in bypassing the likes of Shell etc and cutting down the amount of 'fuel miles' by buying locally but that is about it.
