Production of paper from pineapple leaves

Abstract

Wood is used as the major raw material in paper production around the world and this has resulted in severe deforestations having direct negative impact on our environment. This has led to the need of finding alternative raw materials for paper production. Mauritius has around 300ha of land under pineapple cultivation resulting in agro-waste materials of the leaves. This paper aims at determining the feasibility of using pineapple leaf fibres for paper production. Samples of pineapple leaf fibre were mixed with cane-bagasse in different ratios namely, 20:80, 40:60, 60:40, 80:20,100:0. Pineapple leaf fibres were also mixed with wastepaper in the same ratios. Pulping of pineapple leaf was achieved through soda pulping at a concentration of 15%w/v for 90min at 90°C. The papers obtained were tested for their physical and mechanical properties. The average thickness of all the papers produced, ranged from 0.232mm to 0.304mm showing an increase in paper thickness with increasing grammage from 58.19g/m2 to 63.3g/m2. The most absorbent paper(1.19s) was found to be the 100% pineapple which also demonstrated the highest Tensile Index and Burst Index (6.5Nm/g and 0.84kPam2/g respectively). The bagasse and pineapple composite of ratio 40:60 was found to be the most abrasion resistant paper with 21 turns and a weight loss of 0.86% with the use of emery paper of grade zero as abradant and 200g load cells. The most crease resistant paper was the wastepaper and pineapple composite of ratio 80:20 with a crease recovery angle of 59.8°.
