A Biorefinery for Orange Waste Valorization

Short Introductive summary

In this work, rhe compositional analysis of orange residues is presented. The production of biogas and bioethanol from these residues was evaluated in comparison to conditions where pectin and essential oils are removed. The compositional analysis showed that orange waste contains considerable amounts of hemicellulose (28.0 ± 0.77%), pectin (26.4 ± 0.35%), and extractives (18.7 ± 0.58%). The maximum methane production was obtained using the untreated residue (291 ± 2.7 mL CH4/gVS), which produced 4.5 times more methane than the inoculum alone. The production of ethanol and glycerol is enhanced due to the presence of essential oils and pectin in comparison to the other conditions. A maximum concentration of 43.9 ± 5.5 mg/L of ethanol and 1.8 ± 0.08 mg/L of glycerol were obtained using the untreated residue. Main phytochemical substances were identified in the extracts showing the possibility to produce biogas and bioethanol in conjunction with the retrieval of oils, terpenes and polyphenols.
