Characterization of lignin isolated from paper mill effluent

Waste is not a waste it will become resource if properly utilized. Instead of releasing lignin through effluents into water bodies from paper & coyer board manufacturing units, It may be better option to extract it from effluents and to use binder, dispersant, emulsifier, sequestrant in an eco friendly way. Here an attempt has been made to characterize the lignin isolated from effluents of Andhra Pradesh Paper Mill located at Rajahmundry by elemental analysis, methoxyl analysis and molecular weight analysis, UV, IR and H-1 NMR spectroscopy. The C-9 formula for lignin was C9H9.36O4.56 (OCH3)(1.23) and the lignin was guaiagyl-syringyl type.
