%X Biomethane potential production from cashew nut
hulls, an agricultural waste, was carried out using old and fresh hulls as
substrates. Samples were taken from old hulls (around 8 years old) and fresh
hulls produced in cashew scale transformation units at Bobo Dioulasso/Burkina
Faso. Physicochemical parameters showed that cashew hulls can be a good candidate for anaerobic
digestion. But high acidity, total phenols and lignin tenor could be a
constraint for anaerobic bacteria. Theoretical biochemical methane potential
showed high value of 666.937 CH4 L. (Kg VS)-1 and 526.206 CH4 L. (Kg VS)-1 for crushed fresh and powdered old hulls, respectively.
Experimental biochemical methane potential showed significantly low potential
of 1.982 CH4 L. (Kg
VM)-1 and 46.840 CH4 L. (Kg VM)-1 for fresh and hold hulls, respectively. Pretreatment for
optimization, chemical composition and co-digestion system must be expected for
a better anaerobic digestion performance.
