>The (not so) sustainable biofuels I remember reading some time ago about palm oil converted to biodiesel and immediately became suspicious of the final product as anything but a chance to push the sale of palm oil. soft oils like canola/linseed, and corn are suited best for biodiesel as their final product is at a much lower gel point than coconut or palm. To run a diesel safely at anything but sub-tropic temperatures with a minimum of waxing or smoking, you'd need gallons of stabilizers and modifiers in the mix. the place I remember hearing this being used was Indonesia, and only at around 50% for a passenger rail line. This makes sense as its partially using petrochemical diesel as a cheap additive for gel and flow stability. the UK and EU could improve their biodiesel uptake with better recycling practices. most of east europe is awash in high quality sunflower oil for frying and cooking, and could easily see this waste oil converted.
