Wood products and green chemistry

Key message Green chemistry for and from wood has developed numerous industrial products , namely biosourced , green wood adhesives and preservatives , foams , composite matrices , laminates , hard and flexible plastics , flexible films , and abrasive grinding discs , and their number is still growing . Introduction This review addresses (1) the elimination of toxic aldehydes from the most common wood panel adhesive, the one based on urea, itself a natural product, (2) biosourced adhesives derived from wood or other vegetable matter and used for wood products, and (3) wood and bark tannin-based foams, natural fiber composites using tannin matrices, paper surface laminates and continuous high-pressure paper laminates using tannin-furanics, hard plastics based on tannin-furanic materials and some of their applications, flexible biosourced tannin-furanic films, and biosourced wood preservatives.
