“…Such functionalization increased the anionic charge of the fiber surfaces. Lund and Felby (2001) found that laccase treatment improved the strength of unbleached kraft paper only when carried out in the presence of an oxidation mediator. Wong et al (1999Wong et al ( , 2000 reported related findings in the cases of high-yield kraft pulp and thermo-mechanical pulp.…”

Paper production requires large amounts of cellulosic fiber, whereas the world's forested lands and croplands have a finite capacity to supply such resources. To deal with likely future pressure on forest resources, as well as to hold down costs of materials, publications examined in the preparation of this review suggest that the paper industry will need to implement several concurrent strategies. In particular, the industry can be expected to view recycling as a central part of its activities. Basis weights of various paper-based products can be expected to decrease over the coming decades, and more of the fiber content will be replaced with fillers such as calcium carbonate. Such trends will place intense demands upon chemical-based strategies to enhance the bonding within paper and paperboard. Based on the literature, further progress in reducing the amount of new forest resources used to meet a given set of paper product requirements will require a combined approach, taking into account various fiber attributes, nanostructures, novel concepts in bond formation, and advances in the unit operations of papermaking.

“…Hüttermann et al (2001 prepared a binderless particle board using laccase treatment that exhibited improved tensile strengths but lower water resistance. Much research has been done to develop a completely natural fiberboard by treating fiber with laccase, but none of the methods have been commercialized yet (Milstein et al 1994;Lund and Felby 2001;Felby et al 2004;Nasir et al 2013a;Nasir et al 2014a;Nasir et al 2014b). Felby et al (2002) prepared a laccase-treated binderless board in a pilot-scale production.…”

“…The removal of such compounds during laccase treatments separates the fiber bundles and exposes hydroxyl groups on the fiber surface. Much research has been proposed on producing wood composites from laccase-modified natural fiber, but fiber modification alone cannot achieve the minimum required strength (Lund and Felby 2001;Felby et al 2002). Thus, an enzyme-treated fiberboard can work excellently in combination with adhesive, or it can reduce the quantity of adhesive used.…”

In the last two decades, laccases have received much attention from researchers because of their specific ability to oxidize lignin. This function of laccase is very useful for applications in several biotechnological processes, including delignification in the pulp and paper industry and the detoxification of industrial effluents from the textile and petrochemical industries. This review focuses on laccase-mediated fiberboard synthesis. Growing concerns regarding the emission of formaldehyde from wood composites has prompted industrialists to consider the fabrication of green composites. Laccase-mediated fiber treatments oxidize the lignin component without affecting the cellulose structure. As a result, free radicals are generated on the fiber surface, and these can act as potential reactive sites for further cross-linking reactions in board manufacturing. Binderless fiberboards prepared using such methods can be considered as green composites because the manufacturing process involves no additional resin.

“…Resulting distinguished lignin modifications may have consequences for subsequent fibre behaviour (Barsberg 2002). Lund & Felby (2001) applied a range of mediators in laccase-modification of spruce and pine fibres and found ABTS and PPT (phenothiazine-10-propionic acid) to be effective in enhancing wet tensile strength of paper handsheets made from the pulp. Similar results were obtained with ABTS by Elegir et al (2005Elegir et al ( , 2007.…”
