Enzymatic deinking of used-paper using laccase and cellulase from Metarhizium granulomatis and Aspergillus niger : a sustainable upcycling approach (opens in new tab)

The pulp and paper industry is one of the main pillars of the global economy. The average global paper upcycling rate is 60%, with < 30% paper upcycling rate in India. The present investigation focuses the exploration of enzymatic deinking technology (EDT) for the upcycling of used-paper (photocopied/print) using laccase and cellulase enzymes, produced from fungal isolates. Among all the isolated strains, Metarhizium granulomatis and Aspergillus niger showed maximum enzyme activity for laccas...
