RESUMO

Due to the need to know the economic and energetic viability of castor (Ricinus communis) for the State of CearÃ, one of the main producers of oil seed in Northeast of Brazil, the present work has been developed aiming to elaborate economic and energetic balance of castor production for obtaining the biodiesel in Cearà State. Simultaneously, it was analysed the castor producers profile in the social, personal and organizational. In addition the technological level of the same. The data were collected in Boa Viagem, Tauà and Pedra Branca municipalities. Secondary data were tomeasure obtained from research institutions.

It also observed that on the average, 12,91% the interviewed farmers are using more than 80% of the recommended techniques. The castor production in all the three selected municipalities is economically feafible (profitable), without considering the cost related to family labor. Energy production e consumption ratio of 1.52 indicates that the system for of energy spent on producing castor, biodiesel generates 1.52 unit of energy.
