Treść
Biofuel producers are obligated to achieve certain level of greenhouse gas emission (GHG) reduction in the lifecycle of biofuels in reference to fossil fuels. The current emission reduction level is at least 35% and will increase up to 50% since January 2017 for the existing plants and at least to 60% for a new installations. At the farming stage it is possible to achieve some emission savings in the lifecycle of biofuels with reference to the agricultural feedstock production. In this study GHG emission optimization was investigated with regard to winter wheat yield and N fertilization rate while considering bioethanol production. Using desirability of optimization, risk analysis and uncertainty assessment, it was proved that the GHG emission attributed to winter wheat cultivation can be reduced by 1.7 g CO2 eq. MJ-1 of ethanol produced. This can be achieved primarily with yield increase by 7.9% compared to the median, while changes in N fertilization is of less importance. By selecting winter wheat from farms producing higher yields (5,200-6,929 t ha-1) it is possible to decrease the uncertainty regarding the GHG emissions from 2% to 1%.
