Résumé : [en] We highlight in this poster, the results of biogas production and biochemical analysis based on the anaerobic digestion of each type of the lignocellulosic waste from a banana cultivar (Williams Cavendish: triploid Musa AAA group). These wastes are usually abandoned in the plantation after the fruits have been harvested. There is great interest in obtaining energy from this generally neglected biomaterial, particularly in the contexts of global warming and sustainable development.
