Research on the production of the composite panels from some agricultural residues.

One of the important reasons for environmental pollution is fast depletion of forest resource as a raw material. While many industries utilise forest products as a raw material and uneconomical use of these resources cause extinction of forest. It is really necessary to find alternative raw material source in order to reduce forest consumption. For this reason it is important to study suitability of annual plants fibres or agricultural residues for panel production. This will aid protection of environment and as well as development of environmental friendly technologies. The aim of this study is to investigate the potential utilization of licorice root, hazelnut and peanut husks, corn and cotton stalks in composite panel production. Composite panels are produced in a lab 20mm thick and targeted to 600 and 700 (kg/m3) densityWater absorption and thickness swelling of the panel were measured. Specimens were also tested for modulus of rupture (MOR) and modulus of elasticity (MOE), and for internal bond strength (IB) also were tested water absorbtion and thickness swelling. The results of this study showed that it was possible to produce composite panel utilizing agricultural residues on lab scale. Results indicated all produced boards met the minimum requirement of the particleboard standard TS-EN 312.
