Résumé : |
News thoughts of green research lead scientists to develop environmental friendly technologies in every field. Several research and development activities are going on to attain the 3 R concepts : reduce, reuse and recycle in all areas of science and technology. This review focuses on the recovery of cellulose from paper/wood waste by dissolution in ionic liquids. Ionic liquids are salts in the liquid state exhibiting a melting point and hence not categorised as Volatile Organic Compounds. Cellulose can be recovered from ionic liquids with a relatively homogeneous morphology. The recovered cellulose after modification may be used in coatings as binder, filler/extender, reinforcing agent or as conventional additives such as rheology modifier. Chloride based ionic liquids which hydrogen bond with cellulose, are used for dissolution of paper/wood waste. Although expensive, the ionic liquids can be recycled after the regeneration of cellulose leads to an economical and environmental benign process. |
