This review is aimed at presenting only the most recent concepts and advances of a great majority bio-sourced, sustainable, green, and high-performance wood adhesives derived from carbohydrates, lignin, and tannins that are actively researched as substitutes for synthetic oil-derived adhesives for wood panels. For all these bio-sourced adhesives the review exposes the considerable progresses which have occurred relatively recently, with a host of new approaches and ideas having been proposed and tested, some even implemented, but even with many more already appearing on the horizon.
