Study of the Potentiality of Utilization of Alternative Agro Residues in Manufacturing Particleboards
Mohamad Samir Ahmad El-Kafafy;
Abstract
This work targets the testing of the potentiality of utilization of alternative underutilized agro residues in the manufacturing of single layer particleboards.
Selection of agro residues has been based on their large amounts and seasonal availability throughout the year. Tomato stalks (TS) have been selected as they are not utilized among the other crop residues and are open field burnt. Chemical analysis of the stalks was performed to prove their suitability for application. Their cellulose content (43.11) % and lignin (12.2 %) make TS comparable with flax shives. Optical microscope was used to investigate the particles morphology. Specimens of particleboards of various resin/fiber compositions were further prepared by compression molding under different pressures and resin concentrations.
The specimens were further examined for their mechanical and physical properties. Comparisons with the European standards (En 312: 2010) for particleboards show the applicability of TS as a natural fiber resource for commercial particleboard manufacturing.
Statistical analysis was performed. It has been proven that at a constant level of pressure, higher resin content values result in higher values of modulus of rupture, modulus of
elasticity, internal bonding and thickness swelling due to increase of bonding force and boards density.
Cost benefit analysis has been carried out to investigate the cost of utilization of tomato stalks for commercial particleboard manufacturing. It was found that tomato stalks with resin on (stage before pressing) cost is 0.25 of cost of casuarina tree particles with resin on.
