Abstract
Residues and by-products are the unavoidable outputs of cereal, sugarcane and dairy processing industry which can be resorted economically. Widespread focus on plastic replacement, residue burning and waste reduction had led to characterization and identification of by-products for economic packaging applications. Extensive research work had been done on whey usage in eco-friendly packaging but packaging applications of cereal crop residues, cereal milling by-products and sugarcane bagasse are still in nascent stage. However, research studies on extraction and exploitation of cellulose, hemicellulose and other film forming components from these by-products had been reported for packaging applications but described processes have low techno-commerciality. Current status and innovations in utilization of cereal residue (rice straw, wheat straw and corn cob), cereal milling by-products (husk, hull and bran), sugarcane processing waste (bagasse and sugar beet pulp) and whey based packaging applications as well as application in bio-composites, are discussed briefly in this review.
