I don't buy it, so I'm answering 'in theory' only.SO what are the benefits of biodiesel? Apart from the obvious, is it cheaper?
Yep, 20p per litre reduction of duty.I don't buy it, so I'm answering 'in theory' only.
It's more expensive to make than ordinary diesel, but of course the pump price depends largely on the level of taxation. So it may be 'subsidised' (like LPG) to make it more attractive.
I'm confused by this comment. Nearly all Biodiesel is a result of using waste veg oil after it's primary use.The main perceived benefit is being more environmentally friendly in terms of total carbon emissions. But in fact it's often not significantly better than mineral diesel (depending on where the veg. oil stock came from). It's also touted as being "sustainable" ... which it is ... however land used to grow crops for biodiesel can't grow food, so there's a bit of an issue there. And in some countries they are clearing and BURNING rainforest to grow crops they can sell for biodiesel production, which is a disaster ecologically speaking!
There are meant to be "phase 2" biodiesels on the way which will be manufactured from waste products instead, and these will be significantly better for the environment.

There's obviously a lot of very emotive stuff on the web about deforestation (greenpeace etc.), but this is reasonably objective:
It begs a question though. If rainforest is cut down to plant fuel crops is the carbon balance actually upset?
What I mean is that the palms absorb carbon as they grow, they are then cut and burned but new ones are planted and grow.
