We need a 4wd pickup truck or similar vehicle for our organic farm, but we would like to mitigate its environmental impact as much as possible.
One possibility is converting an older diesel pickup truck to run on pure veg oil. I've seen some articles that say some biofuels pollute as much as diesel and also there is an issue with displacement of food crops. Haven't seen anything definitive, and some of it is related to biodiesel and not pure veg oil, so if anyone has heard other views/scientific results, I'd appreciate it.
Looking into the pure veg oil thing, I can't find anyone in Ireland currently still trading that does the engine conversions, and more importantly, don't see any veg oil suppliers still in business here. Anyone have a link that has eluded my google searches?
