Too often limited to use in firewood, for construction, or furniture, wood has other potentialities with significant prospects. In fact, wood is an important material for the circular economy and the actual desire of our society to get out of our dependence on oil for ecological and economic reasons pushes scientists and industrialists to become interested in valorizing the wood industry byproducts and especially wood polymers and extractives. Among them, lignins and tannins are abundant and represent a main source of phenolic compounds. This chapter refers to the valuation of lignins and tannins. It gives an overview of lignins and tannins, their structures and extraction methods, and summarizes the progress in using these compounds in composites manufacturing, adhesives, foams, adsorbent, and as carbon fibers precursor. |
