I am inserting a biodiesel plant into my model, but I am having a hard time to considere the right efficiency for this process. Since biodiesel is considered a bi-product of the soy complex, I don't know how to tackle this problem. If I use the efficiency of the soy processing (soy is divided into meal, oil and glicerol), I think LEAP will overestimate the amount of biomass (soy) required, since nobody will produce soy exclusively for biodiesel production. Should I create a new primary fuel, lets say, vegetable oil?
