It seems they’re in a unique position because sugar cane grows there, is used in industry, and the leftovers that aren’t usable for anything else can be turned into fuel.
I had no idea Brazil has a unique bio ethanol industry, thanks for sharing.
I'm not very well versed in the subject but this should point you in the right direction!
