摘　　要：<div style="text-align:justify;"> <span style="font-family:Verdana;">The aim of this work was to use fish processing waste (FW) as main substrate for anaerobic digestion. To enhance the biogas production of FW, co-digestion was done with two other substrates: cow dung (CD) and waste of market (MW). Batch test was carried out in an 1</span><span "=""><span style="font-family:Verdana;"> L glass digester in a temperature controlled chamber at 38</span><span style="color:#4F4F4F;font-family:Verdana;">°</span><span style="font-family:Verdana;">C. The following mixtures were carried out: FW with CD respectively at different ratios 100:0% (A), 80:20%</span></span><span "=""> </span><span "="" style="font-family:Verdana;">(B) and 60:40% (C);FW with MW at the following ratio 80:20% (D);FW with CD and MW respectively at these ratios 80:10:10% (F) and 60:20:20% (G). The biogas produced was measured using a milligas counter</span>^{<span style="color:#4F4F4F;"><span style="color:#4F4F4F;font-family:Verdana;">&#174;</span><span style="font-family:Verdana;"></span></span>}<span "="" style="font-family:Verdana;"> and the volume of gas was recorded. The gas composition was determined using gas chromatography. With a pH stable for raw substrates and mixtures, TS and VS (%TS) contents for FW were respectively 31.01% and 91.55%. Between 3 to 13 days of experimentation, the highest flow rate was observed. The percentage of methane was more important for mixtures B and D, 61% and 59% respectively. pH and VOA/T</span><span "="" style="font-family:Verdana;">IC were stable at the end of the batch test for all mixtures, meaning that the organic matter was already well digested. The highest values of Volatile Solid Removal (VSR) were found for mixtures C, D, F and G. Therefore, the promising mixtures for next experimentations in large scale are B and D.</span> </div><div style="text-align:justify;"> <span style="font-family:Verdana;">The aim of this work was to use fish processing waste (FW) as main substrate for anaerobic digestion.
