摘要: This work aimed to analyze the energetic consumption of etanol production system, using cassava as carbohidrates source. The researches were carried out from field in mid region Paranapanema river, Sao Paulo state, during period January December, 2007. energy referring phases crop and industrial processing appraised. It was verified that total cost corresponded 9,528.33 MJ ha-1, most onerous item inputs (35.72%). In step, equivalent 2,208.28 t-1. operations hydrolysis/saccharification/ treatment juice represented 56.72% expenditure. presented an 1.54 L-1 relation produced main agronomic production, 11.76 processing. efficiency observed cultivation industrialization 1.76.
