A key entry point for lignin in adhesive subsector is expected to be the development of fibreboard. Gel permeation studies in the treatment of lignin in laccase beech fibers demonstrated significant enhancement in lignin molecular weight. It directly confirms that there is a possibility of lignin covalent inter-bonding occurrence. In addition, model compound experiments revealed that laccase treatment of compounds of the lignin model induces molecular weight increases that can respond further to cross-linking increases [84]. Given the growing regulations on the limitation of chemical use in the formation of fibreboard, alternative, cleaner supplies are likely to be pursued.
