<br/><br/> Anaerobic digestion is a well-known 'technique for wa.'ite management<br/>which could have constituted health' ha=ard as well as environmental<br/>pollution. To enhance the biogas production, Starter Digestate (SD) by<br/>5% of digester l'olume (F2J and Agricultural Wastewater (A W) with SD<br/>(F3) were pel/ormed on raw materials of Cattle Dung (CD), Poultry<br/>Droppings (PD). Sugar beet Leaves (SL) and Water Hyacinth (WH)<br/>compared with blank test (FI) (Fap water) under different fermentation<br/>mixtures in order to study their effects on biogas and methane production,<br/>total nitrogen and pH.<br/>Results indicated that using agricultural wastewater and starter digestate<br/>5% (F3) acheived the highest biogas production, methane percentage and<br/>total nitrogen comparing with the other treatments. With respect to<br/>fermentation mixtures, mixture of 50% SL + 50% WH (B) gave the<br/>highest methane percentage (77%), while mixture of50% PD + 25 % SL<br/>+ 25% WH (D) produced high concentration of N (5.3%) as a rich<br/>fertili=er with an average biogas production (778 mUday) through<br/>fermentation period of24 days.
