• Alternatives for lignocellulosic pulp delignification using polyoxometalates (POM) and oxygen were investigated. In the past 10-15 years, significant efforts toward the substitution of chlorine dioxide by environmentally friendly pulp delignification systems employing polyoxometalates were made. A novel integrated system was developed in which the delignification of pulp by a POM and the re-oxidation of the POM by laccase occurred in separate reactors. The results showed that in the aerobic approach, the lignin oxidation and the reactivation of the POM took place in the same stage of the process. The results suggested that the development/optimization of new/known processes incorporating delignification and re-oxidation of the POM in different stages should be considered.
