Progressive depletion of conventional fossil fuels with increasing energy consumption and greenhouse gas (GHG) emissions have led to a move towards renewable and sustainable energy sources. In this work, carob pod (Ceratonia Siliqua) is proposed as an economical source for ethanol production, especially, in arid regions. The carob tree is an evergreen shrub native to the Mediterranean region, cultivated for its edible seed pods and it is currently being reemphasised as an alternative in dryland areas, because no carbon-enriched lands are necessary. The global process of bioethanol production from carob pod by Saccharomyces Cerevisiae yeast cells were analyzed in a previous work. To take into account environmental impacts of the process, a Life Cycle Assessment (LCA) technique was applied, which allowed detailed analysis of material and energy fluxes. On the life-cycle basis, the net energy yield of carob pod (2.36 MJ/MJ) was found to be similar than to those values for traditional crops (i.e. Wheat, 2.25 MJ/MJ).
