Recent decades have seen a significant rise in coffee and tea production, consumption; consequently increase in their waste generation. Alternative routes are necessary for the waste management, to develop a new treatment that would be viable both technically and economically. The purpose of this study is to extract oil from the Spent Coffee Waste (SCW) and Spent Tea Waste (STW), individually with further extraction of bioactive compounds from coffee oil, as well as the production of bioethanol from the left-over solid waste after oil extraction. The extraction of oil was done using Soxhlet apparatus using hexane as solvent while bioactive compounds were extracted using hot saponification. After oil extraction, the residual waste was optimized for glucose level using acid hydrolysis and steam distillation for bioethanol production by fermentation using Saccharomyces cereviciae. Acid Hydrolysis provided the best bioethanol production from the SCW (5.78 g/L, 79.8 % efficiency) and Steam Distillation provided the best bioethanol production from STW (8.47 g/L, 79.4 % Efficiency). Coffee oil has High (86.92 %) antioxidant capacity comparing to Tea oil (52.57 %). The results showed the spent wastes of coffee and tea as potential feed stocks for the extraction of oil, bioactive compounds and bioethanol production.
