See, I told you that politicians and other useless debris could be rendered
into fuel!

Its like _Fight Club_, except that instead of harvesting and nitrating the glycerin
(obtained via esterification or saponification of human fat) you are using the fatty fragments as fuel; you could also turn them into soap, as in FC. In the biodiesel case, the glycerin is also waste, and could still be nitrated. See, fats are glycerin linked to fatty chains; you can add an alcohol group to the chains for biodiesel, or add an alkali metal and get soap; in either case you free up a glycerin.
