Energy pot&ial of the rural area of “La Libertad” departm& (Peru) produced by biogas obtained from human waste. Tecnología en Marcha [online]. 2017, vol.30, n.4, pp.108-117.

From year 2000, the energy potential of human waste has been given more attention due to its biogas production capacity. This is an alternative with a high impact in rural areas where resources and precarious conditions do not allow access to basic services such as electricity and slow the development of the community, and where in turn it can reduce the emission of CO2 to the environment compared to the traditional form of energy generation (coal and wood).

In Latin America, there are extreme poverty areas which require attention and help to begin their development process. Human waste are highlighted as an unexploited resource, which with a biotechnological process and treatment to eliminate pathogenic organisms can become an energy source for the population.

This study determined the energy potential of human waste in rural areas of the Department of “La Libertad”, where 7 of the 20 poorest districts in Peru are located. It was estimated that the total rural population by 2017 in the area will be 468,979 people, from which 3427.49 Nm3 / day of biogas can be obtained which represents 1’251.033 Nm3 of annual biogas if the total waste is use. The biogas that would be generated in 2017 represents an energy potential of 7’506,198 kWh, which can be transformed into 2’251,859 kWh of electricity, valued at US $ 245,685 per year.
