Olive Pit Oil: Drizzle It on Your Engine Block

Olives produce olive oil. Olive pits produce—bioethanol?

According to a new study published in the Journal of Chemical Technology & Biotechnology—required reading!—scientists in Spain have used olives to make oil for cars as well as salads: First, take a large pressure cooker. Add olive pits. (If using pits from all yearly olive pit waste, that’ll be 4 million tons’ worth. Invite friends over to help out.) Add enzymes to break down pits and produce sugars; ferment sugars into fuel. Do not drink.

This has been the first of CHOW’s step-by-step bioethanol recipes. This will not be a regular series.
