Just to mention two figures, in 2009 the sugarcane-ethanol chain produced 604 billion liters of vinasse and 201 million tons of bagasse and filter cake.

The process of organic waste biodigestion is quite old, as the first unit was installed in Bombay, India, in 1819; in Australia, a company has produced and industrialized methane from sewage since 1911. China has 4.5 million biodigesters that produce gas and organic fertilizer, the main role of which is sanitation in rural areas. However, different aspects related to biodigesters are still lacking. This work aimed at studying and improving a biodigester system, and its general goal was the devel
