Anaerobic Co-Digestion of Fish Processing Waste with Cow Manure and Waste of Market (Rests of Fruits and Vegetables): A Lab Scale Batch Test

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