Physical properties of paper made from pineapple leaves

Pineapple (Ananas comosus) is one of the most widely grown tropical fruits, and its production results in a large quantity of agricultural waste, mainly in the form of leaves. This study was conducted to produce biodegradable paper from pineapple leaves without the use of bleaching agents or starch. The pineapple leaves were used instantly without fiber separation. The starting of the processes began by soaking the leaves in a 5% sodium hydroxide (NaOH) solution to soften their structure. After that, the leaves were washed, blended with water and manually formed into paper sheets. The paper quality was observed based on physical appearance, weight, and estimated thickness. The findings showed that alkaline treatment helped soften the leaves and enabled the formation of paper with natural bonding. The resulting paper appeared fibrous, lightweight, and suitable for basic use. This study shows that pineapple leaves, usually thrown away, can be turned into eco-friendly paper using a simple and low-cost method. It is especially useful for small industries or countryside areas.
