Mr Santos was a founding investor and director of Solmino Renewable Energy, a Brazilian sugarcane ethanol company. He worked closely with Solmino management to raise more than $150 million. His involvement in the sugarcane industry dates back to the early 1990s when he advised a Brazilian sugarcane co-operative.

Ken Milken, CEO of Southridge, said: We are extremely fortunate to have Mr Santos join the board, during this critical period of our company’s development in Brazil. With over 20 years of experience, Mr Santos will facilitate and expedite the completion of our production facilities and our ethanol export operation in Brazil.
