Biotechnology

Enzyme catalyzed processes are fast replacing chemical processes due to low environmental impacts, better product quality and lower requirements of water, energy and chemicals. Enzymes have found several applications both in virgin fibre and secondary fibre processing including enzymatic pre-bleaching of vigin pulp, bio- refining, bio-deinking, pitch &stickies control etc. Besides Cellulases and Xylanases, host of other enzymes like Lipases, Esterases, Amylases, proteases and Peroxidases have found use in Pulp and Paper Industry.

Objective of biotechnology laboratory–to establish and promote biotechnological applications in pulp and paper industry by undertaking R & D activities, provide technical services to paper and allied industries, skill development by way of training industry personnel and conducting dissertation project work of graduate and post graduate students
