BIOGAS PRODUCTION POTENTIAL USING ANIMAL WASTES AS A SOURCE OF ENERGY FOR SELF RELIANCE AND SUSTAINABLE DEVELOPMENT - A CASE STUDY OF KATSINA STATE ABATTOIR, NIGERIA.

Abstract

Abattoir wastes can be converted to biogas production. This paper presents the potentials of biogas plant In Katsina abattoir because the visceral wastes are polluting the abattoir with its surroundings. The effect of four different rumen dung’s slurry concentration (1:1, 1:3.1:4 and 1:5) at 30 days retention time was studied at Ibrahim Shehu Shema center for renewable energy (ISSCRE) of Umaru Musa Yar’adua University Katsina. The result shows that biogas yield in 1:3 and 1:4 were significantly higher than those at 1:1 and 1:5 concentrations for a given retention time. The outcome of the research suggest that biogas production is in order of 1:3>1:4>1:5>1:1, which means that further increase In substrate concentration result in the decrease of the specific growth rote which result in lower gas production. The rumen Dung was examined for PH and specific gravity. The mean rumen PH values were 6.98± 0.03 and 7.14 ± 0.04 for camel and cattle respectively. While mean specific gravity values were 1.016 ± 0.005 and 1.005 0.001 for camel and cattle respectively. The study reveals that for optimum biogas production, the slurry could not be too much concentrated or too much diluted to substrate ratio
