Development of anaerobic biodigesters for agricultural waste treatment, energy generation and use of effluents in agriculture

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 development of biodigesters with improved performance, aiming at the correct treatment of residue derived from agricultural activities, and generating clean renewable energy as well as low-cost, duly disinfected fertilizer.
