Two years later, Professor Expedito Parente, of the Ceará Federal University, discovered biodiesel made from cotton oil and, in 1980, he registered the first world wide biodiesel patent, now in the public domain. Throughout the world, with the passing of the years and the intermittent energy crises, associated to a greater demand for fossil fuels, new and strong stimuli emerged for the development of production technologies both for ethanol and biodiesel. These two products are starting to have a leading role in the world’s energy matrix and in the international fuel market. Thanks...
