Abstract

Comparative study of anaerobic digestion of rumen, municipal waste and co-digested feedstock each investigated. 10kg each of rumen, municipal waste and co-digested feedstock each was used in 30 liters anaerobic digester. The digester was loaded batch wise for 30 retention day runs up to 80% volume of the digester nominal volume. The cumulative biogas production was recorded as 181900,217350 and 180250 ml/g VS-1 respectively. Methane composition of the various biogas was 56.42, 55.81 and 58.820% untreated biogas samples. The treated scrubbed water produced a burning gas with methane composition 84.08, 51.54 and 95.518% respectively for the feedstock. Co-digested substrate does not actually have any significant effect on production and composition of the gas produced. Since waste raise a major environmental concern, these simple steps could be exploited by small and medium scale entrepreneurs (SME), an alternative to convert waste into fuel that can be tremendously useful as renewable fuel source especially for domestic and industrial use.
