JIMENEZ BORGES, Reinier; LOPEZ BASTIDA, Eduardo J.; GONZALEZ PEREZ, Félix  e  CURBELO GARCIA, Javier Alejandro. Preliminary evaluation of the energy potential of different biomasses in the Cienfuegos province. cen. az. [online]. 2018, vol.45, n.2, pp. 25-32. ISSN 2223-4861.

This paper presents the used methodology to calculate the present and future potentials of total biomass wastes, from the economic, social, environmental and technological point of view in accordance with the principles of sustainable development. From the values of sugarcane, coffee, rice, and sawmill wastes, through information provided by the main producing companies in Cienfuegos province, it was possible to determine the total energy delivered, as well as the amount of CO₂ emitted into the atmosphere. In the case of the bagasse, the total energy was 4.409E+08 MJ, leaving 137 652.9 t CO₂ to emit in the atmosphere. For the filter cake it was 7.093E+08 MJ and 221 423.9 tCO₂. In the case of coffee and rice residues these values were 4.808E+05 MJ with 184 tCO₂ for coffee and 6.34E+07MJ with 19 868.87 tCO₂ for rice, respectively. Finally, the total energy for sawmill waste was 4.108E+07 MJ and 2 346.72 tCO₂.
