摘要：This study shows the effects of cassava starch as binder on the flexural strength andthe water absorptivity properties of cassava starch bonded paper pulp basedcomposites. Paper pulp was produced by chopping waste papers into smaller piecesand soaked in water for 2 weeks after which it was pulverized in the grinding machineto form paper pulp. The starch slurry was prepared with boiled water and stirredproperly to produce lumps free starch slurry. The starch slurry after cooling waspreserved in a container. The composites were developed by forming thehomogeneous pastes from the mixture of starch with white and brown papers slurry,respectively in predetermined proportions. The developed composites were allowed tocure at room temperature in the laboratory for 28 days after which flexural and waterabsorptivity tests were carried out on the samples. It was deduced from the work thatboth white and brown paper pulp based composites possessed improved propertiesthan the control sample which was without starch. However, starch bonded brownpaper pulp based composites gave the best bending properties while starch bondedwhite paper pulp based composites gave the best water absorption resistance response.
