Eficiência na produção das principais matérias-primas vegetais exploradas para o biodiesel no Brasil.

The Brazil, to accomplish your appointments about climate changes (Paris Agreement/2015 and COP26/2021), established annual goals of descarbonization to the fuels department. This study analyze the efficiency of the oilseeds production classified as fixed oils or triglycerides, demanded by the biodiesel industry. The efficiencies' analyze of the technique was a Data Envelopment Analysis. The output was the production volume, the inputs were the fixed variables and costs, collected from July to September/2021 on official digital platforms. Were selected the soy, the corn and the cotton that have been part of the biodiesel production base since 2011 (from 49 producing counties). Of 23 soy productors, 13 have maximum efficiency and 10 needs adjustments to become efficiencies. Among the efficiencies the produced soy kg/ha medium cost is R$ 1,09, among the inefficiencies is R$ 1,25 (14,67% increased). Among the 19 corn producers, 6 has the maximum efficiency and 13 needs adjustments to become efficiencies. Among the efficiencies the corn kg/ha medium cost is R$ 0,54, among the inefficiencies is R$ 0,66 (22,25% increased). Of the 7 cotton producers, 6 has the maximum efficiency and 1 is inefficient, between the efficiencies the cotton kg/ha medium cost is R$ 6,54, and in the inefficient is R$ 7,90 (20% over). With the adjustments mostly in SSFP input the seeds/seedlings, fertilizers and pesticides 24 or 49% of 49 producers counties can reach the maximum efficiency. [ABSTRACT FROM AUTHOR]
