Agência FAPESP – Biorefineries, as are called the industrial complexes that produce fuel, electricity and chemicals from biomass, are becoming enterprise capable of converting a wide variety of materials, including agricultural waste, into several products. This process with more energy efficient, economic and environmental benefits compared to conventional technological processes that give rise to only one or two products.
According to Jonas Contiero, a professor at Universidade Estadual Paulista (UNESP), Campus of Rio Claro, the first biorefineries plants were characterized by production of ethyl alcohol by grinding dry grains such as raw materials and have a line of fixed production , which consists of ethyl alcohol in co-products and carbon dioxide.
Later, began to emerge in second generation Biorefineries that use technology for grinding “wet”, which enables the production of various final products, depending on demand, using mainly grains as raw materials. There are currently undergoing research…
