Abstract

Citrus fruits are among the world's most important crops, with annual production exceeding 160 tons. However, their industrial processing generates substantial amounts of waste (mainly peels, seeds, and pulp), which can represent up to 50% of their total weight. This review examines innovative strategies to valorize these byproducts. Research shows that citrus residues (CR) have great potential for extracting high-value bio composites or converting them into biomaterials, going beyond traditional uses such as animal feed and biogas production. Special attention is paid to emerging applications in nanotechnology, nutraceuticals, biodegradable materials, and functional coatings. In line with the principles of the circular economy and green chemistry, this study highlights the potential of citrus residues to address major sustainability challenges while fostering the development of new market opportunities. The review also critically assesses current limitations related to scalability, regulatory frameworks, and consumer acceptance, with global and regional implications.
