Abstract: Fabrication of a cost effective, laboratory scale flotation device that can be used for deinking of various grades of wastepaper has been described. The unit consists of aeration device, sparger, baffles for high air to stock ratios and high shear mixing. The sparger is designed in such a way, that, it gives micro turbulent airflow necessary for removal of smaller ink particles. The deinking experiments using alkaline active cellulases from an alkalotolerant Fusarium sp have been reported. The enzyme preparation showed different cellulolytic and xylanolytic activities. Successful application of cellulases in enzymatic deinking of mixed office waste paper has been described.
