Previous to 2008, Brazil’s petroleum industry had a voluntary system where diesel was to include at least two percent bio fuel. This year, in 2008, it is now enforceable law and in 2013, the amount will increase to five percent. And since Brazil is known for its coffee beans, the defective or 
inferior beans have been seen as excellent raw materials for bio fuels. Not only does removing the beans from the international and local bean supply produce better coffee supply, but it also provides another useful purpose for the beans.
In conjunction with Sindicafé (Sao Paulo Coffee Industry Union), the Federal University of Minas Gerais conducted tests to ensure the product’s viability. Not only is the reliability of the product important but also, the economics of using the beans for bio fuel versus selling the inferior beans to other coffee related industries. And even if proven that the bio fuel can work, there will be many steps to ensure the ideal comes to fruition. But in the meantime, individual companies within the coffee bean sector may choose to fuel their equipment with the diesel, as it will be much cheaper than gas stations. Further, the process is less expensive than using other food products because the supply of coffee bean oil already exists.
Other oils that Brazil is testing are castor oil, palm oil and soybean oil with the intent of diversifying the raw materials used to produce clean burning bio fuels.
