Citrus peel waste is rich in biopolymers and the biomass energy in it can be recovered by anaerobic digestion bioprocess. Nevertheless, the process instability is a common operational issue during anaerobic digestion of citrus wastes. Bioprocess monitoring, control, and microbial management are key points to control instability and increase the energy conversion efficiency of anaerobic digesters. Factors affecting anaerobic digestion process, particularly due to physicochemical properties of the substrate and the formation of undesirable compounds during the process, and their effect on microbial bioconversion efficiency during anaerobic digestion are discussed. Further, advances on anaerobic digestion of citrus wastes are analyzed and discussed in this paper along with perspectives and opportunities for future are presented in this paper.
