The natural glue holds the cellulosic fibers together in the plant body, thereby providing rigidity and strength. Despite this, lignin shows promising relevance for biomaterial production due to its abundance, nontoxic nature and biodegradability. Considerably, adhesive components were derived from petroleum, which is increasingly more expensive. Hence, lignin, the natural glue in plant materials, gained much popularity because of its phenolic nature, making it an attractive substitute for adhesives. Lignin-based binders are produced through phenols substitution in phenol-formaldehyde resins with lignin due to their similar structural framework. Many researchers have confirmed the multifunctional applications of lignin, such as wood adhesive in fiber board, plywood and particleboard, a binder in printed wiring boards, abrasive tools, epoxy asphalts, epoxy wood composites, 3D printing, adhesive hydrogels, soil suppressants, lignocellulosic paper and coatings. This review presents a comprehensive description of the utilization of lignin-based binders for different applications. The present work highlights the discussion on the various methods by which lignin can be used to replace synthetic binders. This review focuses on global research work introducing lignin in different chemical adhesives for a more cost-effective and less harmful alternative.10abinder10abiodegradable10alignin10amultifunctional1 aMili, Medha1 aHashmi, Sayed, Azhar Rash1 aAther, Madeeha1 aHada, Vaishnavi1 aMarkandeya, Nishant1 aKamble, Sanjay1 aMohapatra, Mamata1 aRathore, Sanjai, Kumar Sing1 aSrivastava, Avanish, Kumar1 aVerma, Sarika  uhttps://library.ncl.res.in/content/novel-lignin-natural-biodegradable-binder-various-sectors-review
