Aim. Main aim of this research was the evaluation of theoretical bioethanol yield (per ha) from hexaploid giant miscanthus (Miscanthus х giganteus) and further comparison with conventional triploid form as well as with other bioethanol crops. Methods. Several mathematic functions were determined that describe yearly yield dynamics and equations, which were used in calculations of theoretical bioethanol yield. Results. The theoretical bioethanol yield was evaluated for different hexaploid miscanthus lines. The most productive in terms of ethanol yield were lines 108 and 202, from which potential bioethanol yield was found to be higher than in control line (6451 L/ha) by 10.7 % and 14.2% respectively and can reach 7144 L/ha and 7684 L/ha. Conclusions. It was determined that the most productive lines of polyploid miscanthus (lines 108 and 202) are able to compete with other plant cellulosic feedstocks for second-generation bioethanol production in Ukraine. However, these lines show bioethanol productivity than sweet sorghum, in the case when sweet sorghum is processed for obtainment of both first- and second-generation bioethanol. Keywords: bioenergy crops, biofuels, giant miscanthus, Miscanthus, polyploidy, second-generation bioethanol.

The sustainable development agenda of the United Nations aims to ensure affordable energy for all and to diminish greenhouse gas emissions in order to mitigate the effects of climate change. A way to achieve these goals is by the substitution of fossil fuels with biofuels. This study compares three Andean countries: Colombia, Ecuador and Peru, in terms of bioethanol blending mandates current scenario and its sustainability. For this analysis, a review of the state of the art of first and second generation bioethanol in the three countries were developed, including a social network analysis to understand the interactions that have enhanced or delayed the achievement of their blending objectives as countries. So far, Colombia is near to reach its blending target; Ecuador has recorded a bioethanol deficit, estimated at 75%; and regarding Peru, in the last years they have achieved their national target. In addition to blending mandates, the countries appear not to rely on a sustainability policy for the development of first or second generation bioethanol. Furthermore, these Andean countries are planning to increase their blending targets. In order to achieve this, political efforts must be focused on feedstock availability as well as on the development of guidelines related to sustainability and technologies to be applied in their own context.
