The anaerobic co-digestion of pineapple wastes with vinasse presents a promising approach for addressing waste disposal issues while generating sustainable energy sources. The reactors R1, R2, R3, R4, R5, and R6 were subjected to H2O2 pretreatment and thermal pretreatment, while is pure vinasse. Addition of various amounts of granular activated carbon to the mixture in a 700 mL working volume was used to enhance biomethane production. Each reactor contains identical amounts of nutrients and inoculum. The present study showed that the highest biomethane yield of 78.7 mL/g VS was obtained in compared to the other batch reactors. After 30 days of anaerobic co-digestion, the content of the reactor producing the highest biomethane yield (R5) was tested for BOD and COD. Physico-chemical parameters such as TS and VS values decreased substantially with removal efficiencies of 0.55% to 42.33% and 71% to 77.7%, respectively.

摘要

The anaerobic co-digestion of pineapple wastes with vinasse presents a promising approach for addressing waste disposal issues while generating sustainable energy sources. The reactors R1, R2, R3, R4, R5, and R6 were subjected to H2O2 pretreatment and thermal pretreatment, while is pure vinasse. Addition of various amounts of granular activated carbon to the mixture in a 700 mL working volume was used to enhance biomethane production. Each reactor contains identical amounts of nutrients and inoculum. The present study showed that the highest biomethane yield of 78.7 mL/g VS was obtained in compared to the other batch reactors. After 30 days of anaerobic co-digestion, the content of the reactor producing the highest biomethane yield (R5) was tested for BOD and COD. Physico-chemical parameters such as TS and VS values decreased substantially with removal efficiencies of 0.55% to 42.33% and 71% to 77.7%, respectively.
