Production of biogas from Co-Digestion of Goat Manure and Watermelon (Citrullus lanatus) Fruit Peels under Anaerobic condition

Abstract:

Biogas production is one of the technologies that can overcome the problems related to energy Crisis. Therefore, this research was conducted to investigate the biogas production potential of Xanthium strumarium leaves in combination with goat manure in anaerobic condition. Completely randomized experimental design was used under mesophilic condition (38ºC). Five batch fermentation treatments (T1=100% goat manure, T2=75% goat manure:25% Xanthium strumarium, T3=50% goat manure:50% Xanthium strumarium, T4=25% goat manure:75% Xanthium strumarium and T5=100% Xanthium strumarium) was used with triplicate in total solid content adjusted to 8% in 0.5 plastic bottle digester for 30 days of fermentation period. In all treatments, Physico-chemical parameters such as total solids (TS), volatile solids (VS), organic carbon, total nitrogen, carbon to nitrogen ratio and pH were measured and were significantly varied before and after anaerobic digestion (P
