Hi
My suspicions were raised whenI tried to filter chip shop oil treated to produce bio-diesel. The stuff coming out of my test reededs was full of fats and oils, which could not be chemically or biologically broken down. It struck me that it was a tad irrisponsible of those guys stuffing this effluent down their drains, which would eventually block up.
It struck me that home made bio-fuels seemed to be more about tax avoidance, than green and friendly. As the resulting effluent is certainly not green and friendly, then what other reason could there be to do this. And as you clearly point out, the area of land required is huge, reducing our ability to feed ourselves.
So thank you for your reply. It is worth considering
