QUETZALLI AGUILAR, Virgen; TABOADA-GONZALEZ, Paul  e  OJEDA-BENITEZ, Sara. Potential production of electricity from biogas generated in a sanitary landfill. Ing. Investig. [online]. 2011, vol.31, n.3, pp.56-65. ISSN 0120-5609.

Energy forms the cornerstone of almost every economic, social and cultural sector in modern societies. Energy is regarded as an irreplaceable ingredient in such societies' industrial development. The aim of this research was to estimate the generation of biogas in the city of Ensenada's sanitary landfill to ascertain the amount of energy which could be generated from the solid waste being disposed of. Biogas estimates were conducted in two stages: a waste characterisation study followed by implementing the regulations proposed by SCS Engineers (SCS Engineers, 2009) regarding the Mexican biogas model (version 2.0). The results showed that a large quantity of organic matter (around 70%) is a key element in anaerobic degradation of waste. As to energy generation, it is believed that a full 1.90 MW capacity will be reached in 2019. Such energy could increase Ensenada's current electricity generation capacity by 3.46% and provide 60% of the energy needed for street lighting, thereby leading to USD $1.423 million in savings.
