Ometto, worth $2.5 billion today, catapulted the sugar mill his grandparents had bought back in 1936 into a sugar and ethanol giant called Cosan S.A. Once upon a time, the sugar mill's focus was sugar. These days, sugar only accounts for 22% of Cosan's sales. With oil prices going off the roof, clean energy getting hotter and 90% of the new car sales in Brazil being flex-fuel, Ometto expects renewable energy and the logistics around it to become an increasingly important part of Cosan's business plan. Two of Ometto's PR reps accompanied me to Da Barra, where we were greeted by a trio charged with showing us the inner workings of a sugar mill that produces five different kinds of sugar, ethanol and electric energy from bagasse (the leftover sugarcane pulp). A van took us around the 70,000 hectares of sugar cane plantations.
