Abstract

Egypt can become a “zero waste country” in the immediate future by using biogas technology which can solve both energy and waste problems.  specially kitchen waste can efficiently be used to produce biogas due to its high calorific value, and biodegradability by microbes. This will reduce dependency on fossil fuels. The current work was carried out to determine kitchen waste composition and characteristics from different standards of living in Egypt and evaluate the effect of living standard on biogas production in Egypt. Kitchen waste collected from three different living standards. There were significant differences among the three living standards H.L., M.L. and L.L. in their total solids (TS%), moisture content % and organic content % and there were not significant differences in their Volatile solids (VS %) and ash content%. By using 9-liter laboratory-scale set-ups, three samples of kitchen waste were digested to indicate the effect of the three standards of living on biogas yield. The results showed that the cumulative gas quantities for the high, medium, and low standards of living were 16.56, 17.59, and 16.44 liters, respectively. The statistical analysis showed a no significant differences between the different standards of living on cumulative gas quantities.
