Biogas technology is one solution that offers the conversion of waste streams to a renewable source of higher value. Anaerobic digestion of organic waste from industrial processes produces energy in the form of biogas, which has an advantage of preventing odor release, and has minimal pathogens. In this study, two different sources of bio-waste were investigated for their biogas potential, namely palm date waste and olive pomace. All of the samples produced biogas; however, the amount produced was only 20% to 40% of what conventional substrates typically produced. Producing biogas that uses only olive biomass offers a solution to the waste disposal problem, but it is not efficient for biogas production. For optimal heat utilization and maximizing biogas production, mixing of different feedstock was identified as a valid solution. Hence, a model of mixing other sources of bio-waste, such as chicken manure, can activate sludge and is proposed to boost the biogas production.en1930-21262017493839395NC State Univ.Biogas potentialGB21 TestOlive pomaceRenewable energyLandwirtschaft, VeterinärmedizinJournal Article10.15376/biores.12.4.9383-9395Other
