Rojas Remis, RebecaMendoza Espinosa, Leopoldo G.2013-04-162013-04-1620121909-0455http://hdl.handle.net/10567/891The population increase in Mexico has demanded an increase of the drinking water and sewer nets. This has brought the construction of waste water treatment plants (WWTP), a fact that has generated more waste water treatment and, at the same time, an increase of the waste sludge produced. Waste sludge is an environmental problem given the quantities, volumes and contamination it generates. Sludge can be used to produce electric energy, though, by the use of anaerobic digestion systems. For instance Mexico alone generates about 640.000 tons of waste sludge a year. The scope of this article is to analyze from an interdisciplinary viewpoint, at a world scale, the use of biosolids to produce energy and be the basis to develop such type of projects in Mexico.esCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráTratamiento de aguas residualesBiometanoLodos residualesDigestión anaerobiaEnergía eléctrica - GeneraciónMéxicoArticle
