Study in the activity of commercial lipase, crude banana esterase and crude tomato cellulase and their application in the deinking of laser jet printed paper waste / Nurul Shafika Azmi

The paper industry is one of the most developed, yet the most polluted industry. Waste paper recycling has increased dramatically in recent times, and will continue to do so in the foreseeable future. The key of recycling process is the successful of the ink removal via deinking process. Considering...
