PRODUCTION OF ADHESIVE FROM CASSAVA STARCH AND WASTE SYNTHETIC MATERIALS

Cassava starch and expanded polystyrene [EP] (Styrofoam) were collected and converted into adhesives. Two starch-based glue were produced from the hydrolysis and dexrination of cassava starch, while the expanded polystyrene was formulated through the dissolution of the solid in benzene. The produced adhesives were tested based on their bonding capacity using four substances: thermoplastic cup, plywood, garden hose and papers. The Expanded polystyrene glue could form bonds with all four materials. The tack/drying time was also recorded during the bonding moments. The rheological properties of the formulated adhesives were studied and it was seen that the glues produced showed properties of a shear-thinning/ pseudo-plastic fluid
