El repte/The challenge
The depletion of fossil-based resources and the environmental concerns of their exploitation require the use of raw materials from renewable and abundant natural sources. Industrial biowaste containing lignocellulosics and proteins is considered as a low-cost biomass of minor commercial added value, usually incinerated for energy recovery. Therefore, its valorisation by conversion into value-added products, such as adhesives, will reduce both the fossil resources consumption and the waste generation.
La tecnologia/The technology
An adhesive composition, comprising a first compound including a lower alkyl vinyl ether-maleic anhydride copolymer and a second compound including at least one compound from natural origin containing hydroxyl or primary or secondary amines groups and/or mixtures thereof. The natural compound can be any of lignin, cellulose, hemicellulose, a polysaccharide, a protein, and/or their derivatives and mixtures thereof. The method consists in properly mixing the reagents in water or in aqueous buffer solution and the removal of the excess of solvent after the reaction.
