Abstract

Identification of suitable specie and determination of suitable age of a tree are two important aspects related to selection of raw material for wood based pulp and paper industry. General procedure adopted for addressing these problems includes the following steps: physicochemical characterization of raw material, morphological analysis of raw material, performing designed pulping and bleaching experiments, evaluation of pulp characteristics and mechanical strength properties of paper sheets. This study attempts to make these raw material selection efforts shorter and simpler using simple additive weighting (SAW) multiple criteria decision making (MCDM) approach taking into account only the proximate-chemical, physical and morphological features of raw materials. A total of four case studies related to selection of suitable specie of Eucalyptus and Leucaena; and selection of suitable age of Acacia and Leucaena species have been presented to demonstrate and validate the methodology of the proposed process. SAW method has been applied to the decision making unit comprising proximate-chemical, physical and morphological characteristics of these raw materials to rank them according to preference for pulping and papermaking. Results achieved in this research are in confirmation of those published in literature and reveal that the SAW method is practical, feasible, and simple to apply for pulp and paper based raw material selection.
