<p><strong>Background</strong>: Anaerobic degradation entails the conversion of substrate organic matter to biogas. A wide variety of substrate has been employed. The biochemical methane potential of twenty market wastes was investigated using rumen fluid inoculum. <br> <strong>Experimental: </strong>The<strong> </strong>proximate properties like carbohydrates, crude proteins, crude lipids, fibre, and moisture levels were determined using standard procedures. The physio-chemical analysis was

The substrates biogas production capacity based on elemental composition, COD, organic fraction composition was investigated.<strong> </strong>However, the BMP experiments were carried out at mesophillic conditions. <br> <strong>Results: </strong>The total biogas production was in the range of 1000 to 3500ml, with a methane composition of 56 – 60%. The biodegradability of the substrates ranges from 71 to 94%, subject to the lignin levels. <br> <strong>Conclusion: </strong>The BMP studies are vital in assessing the methane potential of the substrate without carrying out the experiments. </p>
