Comment Why grow raw materials? (Score 1) 242
I don't understand the need to grow food to be converted to ethanol. It seems stupid and a waste.
ST1 is a Finnish energy producer that converts bio waste to ethanol. IMHO they get the bulk of their material from factories like bread makers. They also gather bio waste from city residents. I'm not completely sure what they do with the waste from ethanol production.
