This study investigated the possibility of producing biogas from tannery waste water (liming and deliming liquors) in Al-Amatounj Tannery in Khartoum. The study is based on laboratory analysis and experimental works which have been took place through a pilot scale anaerobic sequencing batch reactor (ASBR), which’s designed for the digestion process for biogas production. Experiments verified that the biogas production rates were mainly affected by operating temperature, pH, and substrate concentration. Two experiments were carried out in the range of temperature 35–40°C. The gas produced was measured by the liquid displacement system. Meanwhile, the highest biogas yields were 72% of CH4 and 28% of CO2. The production of biogas from 20 L tannery waste water with 100 g yeast , 0.0215m3, and the biogas was generated after three days. The results from this research work are considered as providing useful information and operational parameters and that promotion is more successful with efficient anaerobic codigestion.
