Orange peel waste (OPW) (peels, pulp and seeds) is an underutilised residue coming from the orange juice industry. Its classical applications are cattle feeding and composting, while they cannot ensure a total use of OPW, so landfilling is also common practice. On the other side, OPW is very rich in sugars, polysaccharides, essential oils and polyphenols, so there is a vast literature focused on the development and optimization of technologies and processes to several products from OPW. In this review, papers on OPW-based bioprocesses are visited, discovering a wide landscape that goes from the composting and biogas processes on detoxified OPW (deoiled) to bioprocesses to bioethanol, chemicals, flavours and polymers. All these processes are prone to integration within the 2nd-generation biorefinery framework.
