Alternative fuel for farming
This isn’t new technology; biodiesel was an alternative fuel for farming that powered tractors in the 1930’s and 40’s. Even now, this alternate is finding it’s way into the cars of hard core enthusiasts who run their vehicles off of old cooking grease. Unfortunetaly, this isn’t viable for large scale operations, but, it does serve as a good example in recycling. Also, makes for an interesting hobby!
