Abstract: Anaerobic digestion is an industrial process applied to organic wastes treatment with several environmental and energetic advantages over other forms of treatment and specially when is integrated in the agriculture sector (Möller, 2009; Prochnow, 2009; Chynoweth, 1987). In addition to the organic wastes treatment there is an emerging interest in the production of biomethane as a biocombustible through anaerobic digestion of biomass and / or energy crops (IEA, 2010; Chanakya, 2009; CONCAWE, 2008; Tilche, 2008; Yadvika, 2004; Gunaseelan, 1997; Chynoweth, 1987). Cynara cardunculus L. or commonly known as cardoon is a perennial herb or herbaceous crop native to Mediterranean region, grown since ancient times as a wild plant or as vegetable using intensive management techniques (Ortega, 2007; Fernández, 2006). The average biomass annual production varies from 15 to 20 tons of biomass/ha depending on soil and rainfall with 11% of moisture content and the following biomass partitioning: 40 % stalks, 25% leaves and 35 % capitula (Gominho, 2001 and 2008). Different studies have been shown the high potential of this plant as energy crop: the aerial biomass used as a solid biofuel and the oil from seeds used for the production of biodiesel (Fernández, 2006). However, the interest in their use in the production of biomethane has never been investigated. Different studies show that the addition of biomass or energy crops to the anaerobic digestion of cattle dung or the anaerobic digestion of energy crops residues with the addition of partially digested cattle dung or sewage digested sludge enhanced biogas production and methane yield (Chanakya, 2009; Yadvika, 2004). The goal of the research performed on Cynara cardunculus L. was to increase the knowledge about the use of this promising industrial crop for biogas production in Mediterranean countries or countries with similar edaphoclimate conditions
