Abstract

The pulp and paper making (PPM) wood suitability index (SI) model, a quantitative method for selecting hardwood species for PPM had been developed since about a decade but the suitability indices (SIs) of most Nigerian hardwood are yet to be reported. Using the model, and based on their wood anatomical features, this study determined the PPM suitability of nine Nigerian tree species in relation to Gmelina arborea Roxb., the widely acknowledged PPM resource in the country with SI of 1.00. The tree species evaluated in order of their preference for PPM are Afzelia africana Sm. Ex Pers (1.09), Daniellia oliveri (Rolfe) Hutch. & Dalziel (1.04), Trichilia emetica Vahl (0.98), Azadirachta indica A. Juss (0.86), Annona senegalensis Pers. (0.79), Lannea barteri Engl. (0.66), Bridelia ferruginea Benth. (0.64), Vitex doniana Sweet (0.62), and Anthocleita djalonensis A. Chev. (0.48).The study concluded that three of the evaluated alternative wood resources for PPM namely, A. africana, D. oliveri and T. emetica were about 100% as suitable as G. arborea, while two other species namely, A. indica and A. senegalensis showed substantial compliance (79-86%) with the desirable qualities of the standard wood. However the desirability or otherwise of other important pulpwood properties, which were not built into the SI model, such as growth conditions of the species and their adaptability to plantation techniques, cooking behavior of the wood and ease of pulping, pulp yield and physical properties of the pulp, chemical composition of the wood and physicomechanical properties of the paper sheets should be taken into consideration in making categorical selection of these tree species as alternative PPM resources.
