Brotar Program In 2007, COSAN created the Brotar Program, designed to ensure that all Group employees are fully equipped to carry out the Group’s agricultural activities. The partnership with HR – People and Agricultural Development resulted not only in the technical training of our professionals, but also in the preparation of team leaders, offering them the tools with which they can pass on what they have learned to others. The advantage is that teams are trained in technical matters (theory and practice) by their immediate superiors and, with the help of HR, in behavioral aspects. Program results are carefully monitored in order to ensure quality, safety and respect for the environment.
