Exploring the Possibilities of Producing Pulp and Paper from Discarded Lignocellulosic Fibers

The main objective of this work was to explore the prospects of producing pulp and paper from leftover lignocellulosic fibers. In this study discarded Cocos nucifera fibers were collected from an abandoned site and were washed thoroughly. FTIR analysis, chemical composition and fiber morphology studies were conducted. FTIR showed the presence of holocellulose and lignin in the fibers. Chemical analysis showed the holocellulose content as 37.8 wt%. Fiber length, fiber diameter, lumen diameter and cell wall thickness were observed using microscope and derived fiber indices that determine the possibility of producing paper were evaluated. The derived indices such as Runkel index, slenderness ratio, co-efficient of rigidity, flexibility co-efficient, Luce’s shape factor and Solids factor of the fibers were evaluated as 67.9%, 44.11, 58.83%, 0.199, 0.49 and 278.53x103 respectively. All these indices are in good agreement with fibers recommended and used for pulp and paper production. High lignin content present in the fibers is a limitation and it can be removed through appropriate delignification techniques. Thus the study showed that discarded fibers can be used for producing pulp, paper and allied products.
