The use of waste tallow as a feedstock can reduce costs and improve environmental performance of biodiesel production in comparison to vegetable oils. The objective of this work is to formulate an optimization problem to support decision making of feedstock blend for biodiesel production considering specificities of Brazilian regulations. Cold filter plugging poin, cloud point, pour point, viscosity, cetane number, flash point and density were evaluated by prediction methods as a function of the blend composition, and the appropriate limits were imposed on each property. A numerical example of a multi-period problem is provided, with regulations that depend on the season and the country region where the fuel is to be used.
