“…The ash content was lower than that of non-wood fibers, such as kenaf (4.2%) (Ang et al 2010), rice straw (9.2%) (Rodríguez et al 2008), and pineapple leaves (7%) (Tran 2006). Silica content also indicated a low reading.…”

“…Compared to the pineapple leaves, coir fibers contain a low percentage of ethanol toluene extractives (2.9%), hot water soluble (5.9%), and cold water soluble (7.9%), whereas pineapple leaves have 7.0%, 21%, and 26% composition of extractives, hot water, and cold water soluble, respectively (Tran 2006). The high percentages of extractives in organic solvents are totally undesirable for pulping (pitch problems), bleaching, and papermaking and have a direct impact on pulp yield.…”

The performance of coir fiber in the production of linerboard made from soda-anthraquinone (soda-AQ) pulp was evaluated. Based on chemical analysis, the composition of coir fiber is suitable for the pulping process. Out of nine pulping conditions characterized, a pulping condition of 18% active alkali for 90 min cooking time was chosen. These conditions provided the highest screened yield (48.99%), a low rejection yield (0.27%), high viscosity (11.73 cP), and a kappa number (41) that is acceptable for unbleached linerboard production. Beating strengthened the coir pulp. Analyzing the beating revealed that coir pulp was optimized at 1000 to 2000 revolutions, based on a graph of freeness vs. burst index. For all beating conditions (1000 to 8000 revolutions), FESEM micrographs showed the presence of internal and external fibrillation of the fiber, which gradually increased fiber conformability and improved the inter-fiber bonding within the paper formation. Based on its burst strength of 4.57 kPa.m 2 /g and ring crush test of 1.76 Nm 2 /g, which complies with the minimum requirement of the industry standard, coir fiber can be considered an alternative fiber source for linerboard production.

The objective of this study was to characterize the properties of pulp and paper produced from tea (Camellia sinensis) wastes, an agricultural residue widely available in Turkey, using the kraft-anthraquinone (AQ) cooking method. The chemical components and fiber morphology of tea wastes were investigated. The results indicated that tea wastes had low holocellulose, cellulose, and α-cellulose contents and high lignin content. Also, the suitability of the fiber for pulp and paper production was examined, and the fiber length, fiber width, lumen diameter, and cell wall thickness were measured. According to these values, it was found that the strength properties of papers obtained from tea wastes were insufficient. Therefore, tea waste pulps were mixed with Turkish pine pulps at various ratios. Twelve different cooking experiments were performed on the tea wastes, and the cooking with the best pulp yield was used for mixing. The second cooking, with 0.1% AQ, gave the best yield (33.26%), an increase of about 3.51% compared to the first cooking with no AQ. The physical and optical properties of the papers were also examined. Results showed that paper properties were improved by increasing the Turkish pine pulp rate. Consequently, tea wastes can be used in pulp and paper production when combined with softwood pulps.

“…Lignin functions as an adhesive to bind the cellulose together in the fiber. Lower lignin content makes the fiber strength greater and harder to break (Tran 2006). Pineapple leaf fiber has a low lignin content of 4.28% compared to corn stalk (7.3%) and napier grass (10.8%).…”

“…Figure 1 depicts the process of paper production in the pulp and paper industry. Previous studies have compared non-wood and wood materials for the suitability of their fibers in paper making (Tran 2006). Stenius (2000) reported that the composition of wood and non-wood material can be quite similar.…”

Malaysia is a country that is a rich source of agricultural waste material. Three different crops were studied here, including pineapple (Ananas comosus) leaf, corn (Zea mays) stalk, and Napier grass (Pennisetum purpureum). These crops are characterized as agricultural waste materials in Malaysia and have a high potential to be used as alternative fibers for the paper making industry. The objective of this work was to analyze the chemical composition of pineapple leaf, corn stalk, and Napier grass and to investigate the fiber morphology of these crops. The chemical components analyzed include the following: cellulose (Kurshner-Hoffner method), holocellulose (chlorination method), hemicellulose (chlorination method), ash content (TAPPI method T211-om-93), lignin content (TAPPI method T222-om-98), and soluble sodium hydroxide (TAPPI method T203-om-98). All handsheets morphologies were observed using scanning electron microscopy (SEM). Results indicated each crop has the potential for use as a fiber in paper making. SEM images indicated a condensed composition of the fiber structure. The observed chemical composition and morphology of these three crops indicate their suitability for use as fiber sources for the paper industry.
