In the paper industry, the separation and degradation of lignin in wood pulp are conventionally obtained using chlorine‐ or oxygen‐based chemical oxidants. Laccases have shown to be applicable to the bioremediation of pulp and paper industry waste by effecting direct dechlorination [23]. The oxygen delignification process has been introduced in recent years to replace the polluting chlorine‐based methods. In spite of this new method the pretreatments of wood pulp with laccase can provide milder and cleaner strategies of delignification that also respect the integrity of cellulose. Other uses of laccases for the pulp and paper industry include an improvement in the paper‐making properties of pulp and can be even used for deinking and decolorizing printed papers [23].
