Coconut residues have been widely recognized as a promising source of bioproducts and bioenergy, but full access to its potential polymeric matrix, in general, depends upon some pretreatment stage. Organosolv procedure gained recent attention for being eco-friendly combined with an efficient delignification of lignocellulosic biomass. In this regard, this study proposed a literature review on the Scopus database to track the studies focused on the application of organosolv for coconut residues. A total of 17 studies were identified on this subject, then scoping analysis showed that coconut residue, mainly fibers, treated by organosolv under different conditions, have been tested as an adsorbent, source of nanowhiskers, in ethanol production, and in the reinforcement of product properties. Bibliometric analyses, by means of VOSviewer, revealed that Brazil was the country with the highest number of published papers; along with the terms organosolv and coconut, lignin appeared within the most occurred keywords, which highlights the strong association of the organosolv as a route to extract coconut lignin. In addition, the present work also allowed us to enter into a comprehensive discussion of the future challenges and perspectives toward the development of research that aim to enhance coconut residue end uses.
