CHECHETTO, Rodolfo Glauber; SIQUEIRA, Rubens  and  GAMERO, Carlos Antonio. Energy balance for biodiesel production by the castor bean crop (Ricinus communis L.). Rev. Ciênc. Agron. [online]. 2010, vol.41, n.4, pp.546-553. ISSN 1806-6690.

The castor bean crop (Ricinus communis L.) has acquired prestige due to industries interest in the oil quality and recently for new sources of energy demand. The experiment that served as basis for the data used in this study was conducted at the Lageado Experimental Farm, in Botucatu - SP, 2008. This study aimed to avaluate the crop viability through energy balance and energy efficiency since the implantation until biodiesel production using parameters of consumption in operational management for installation and maintenance of culture harvest and oil production. The soil management operations, sow and harvest consumed the total of 266.20 MJ ha-1, gathering with the fertilizers, pesticides, fuels, lubricants, labor, seed and industrial processing totaled 56,808 MJ ha-1 of energy inputs. The energy production was 72,814.00 MJ ha-1. The industry still lacks studies thal would contribution data collection and more specific energy coefficients. The castor beans cultivation was considered efficient allowing again of 15983.44 MJ ha-1 equivalent to about 415 liters of diesel oil.

Keywords : Energy efficiency; Energy consumption; Energy production.
