should we be using it?
It's not a sustainable fuel source at scale. There's just not enough waste food oil, and supplementing it mean crops as a fuel source. Crops as a fuel source means deforestation and a consequential environmental impact significantly worse than burning fossil fuels.

But this means warmer winters, what's not to like?
It still amazes me people get excited by electric cars that get their electricity indirectly from fossil fuels.

Currently there is fuel available from three sources
From foodstock.
From reconstituted oils from the far east.
From reconstituted oils from Europe.
I guess my question relates to the comparison with our commonly available fossil fuels is it better or worse?
I am aware of the problems of scale but does this mean we should not use it in highly populated polluted cities because of the damage it does whilst being produced or is the benefit worth it?
Waste can and does come from other sources not just old chip fat.

I have been looking at second generation bio diesel referred to HVO (Hydrotreated Vegetable Oil).
Apparently it has been approved for use in Southern California where all municipal vehicles will be required to use it and has been in common usage in Finland and other Scandinavian countries for some years.
According to studies in Helsinki, Leeds and other universities its use results in significant lowering of exhaust emissions'; Particulates -33 to-85%, NoX -9 to-35%, CO -24 to-40%.
Does any one know anything about it ? and should we be using it?
