Nanocellulose and microcrystalline cellulose from citrus processing waste: A review

Used since decades to produce pectin, citrus processing waste poor in lignin and rich in hemicellulose obtained from lemon and orange juice industrial manufacturing is ideally suited also as microcrystalline cellulose and nanocellulose raw material. The study merges the outcomes of chemistry and bioeconomy research between 2007 and early 2024 with technology and economic insight, to reach five conclusions that will hopefully inform practice-oriented work of researchers and bioeconomy company's managers interested in the sustainable manufacturing of these important biomaterials.
