Abstract:

This research investigated the composite panel manufacturing opportunities from alkaloid factory solid wastes. On this basis, three layers composite panels were produced from a mixture of alkaloid factory solid waste (Papaver somniferum L.) and pine wood (Pinus nigra Var. and Pinus brutia Ten.) at certain ratios utilizing urea formaldehyde (UF) adhesive and hardener. 10 types of 18 mm thick panels with an average density of 0.68 g/cm3were manufactured with different raw material ratios (0, 25, 50, 75, and 100%). All panels were tested for physical properties such as specific gravity (TS EN 323), moisture content (TS EN 322), thickness swelling (TS EN 317) and mechanical properties modulus of rupture (TS EN 310), modulus of elasticity in bending (TS EN 310), internal bond (TS EN 319), surface soundness (TS EN 311), withdrawal from face and edge (TS EN 320 and TS EN 13446) and formaldehyde emission (TS EN 717-1). Physical, mechanical properties and formaldehyde emission of panels which were produced with the mixture of poppy husk and pine wood were compared with related standards and literature. According to the results, composite panels are manufactured by using up to 25% and the less poppy husk fulfils the requirements of related standards and literature. Therefore, poppy husk (Papaver somniferum L.) can be utilized as a raw material in composite panel manufacturing by in combination with pine wood. Utilizing the poppy husk for manufacturing composite panel has added two superior features to composite panels by decreasing the cost and formaldehyde emission. Finding this type of a new application area for poppy husk might have the recycling opportunity of Alkaloid factory wastes. Composite materials which were manufactured in this research can be used in industrial design applications, interior architecture and constructions.
