Residues of the transformation of halieutics products: An alternative substrate for energy valorization of wastes by methanisation for a local sustainable development (preliminary results)

The purpose of this study is to evaluate the biogas productivity potential of residues of the transformation of halieutics products. Experiments were conducted in two digesters of PUXIN model of 20 m3, where the temperature is 35°C. Multirae analyser was used to know the composition of biogas produced. A gas counter was also used for counting the amount of biogas produced during the experiment. There was also a...
