“…These R sheets also showed higher tensile indices when compared to those of the rice straw paper sheet prepared from a soda-AQ process (38.0-57.6 Nm/g) in the work of Shao et al [18]. Furthermore, the tensile indices of the present P sheets were also comparable to the values reported in the previous work of Wutisatwongkul et al [19]. They prepared the handsheets from pineapple leaf pulp by a soda pulping process, having the tensile index of around 35.0-46.6 Nm/g.…”

Molded pulp is an eco-friendly packaging product popularly chosen nowadays. It is mostly used to replace plastic containers such as polypropylene (PP), polystyrene (PS) and polyethylene (PE). Besides, the non-wood pulps from agricultural crops and residues have been increasingly studied as alternative materials in pulp production. Therefore, this study aimed to investigate the possibility of utilizing rice straw (R), pineapple leaf (P) and banana stem (B) as raw materials to prepare pulps by using a soda-anthraquinone (AQ) pulping process. The pulping was carried out with 4-7% sodium hydroxide solution and 0.1% AQ, a liquid-solid ratio of 10:1, and pulping time of 15-30 min at 98 ± 2°C. Next, the obtained pulps unscreened (u-) were sieved into screened (s-) portions, and the molded sheets from both u-and s-portions were formed using compression molding technique under pressure of 0.6 MPa at 130°C for 5 min. The molded sheets from R pulp showed higher tensile strength and tensile index (62 MPa and 63.28 Nm/g, respectively) when compared to the sheets from P and B pulps. From SEM images, the cross-sections of the R pulp sheets revealed less voids between fiber layers and, hence, better fiber-packing and bonding. Based on their mechanical properties compared to commercial molded pulp products, it suggested that these agricultural residues and their pulps can be considered promising alternative sources for pulp and molded pulp production.

“…Many studies have been carried out to fi nd new alternative lignocellulosic materials. Some of these studies have used tobacco (Shakhes et al, 2011a), rice straw, sugarcane bagasse and cotton stalk (Adel et al, 2016), pineapple (Wutisatwongkul et al, 2016) millet stalks and date palm leaves (Saeed et al, 2017b), J. procera (Nasser et al, 2015), sunfl ower stalk (Barbash et al, 2016) gracilaria and eucheuma (Machmud et al, 2013), bitter orange (Tutuş et al, 2016), ipomea carnea and cannabis sativa (Dutt et al, 2008), c. orientalis and c. tataria (Tutus et al, 2010), wheat straws (Espinosa et al, 2016) and broad bean, bell pepper and asparagus (Gonzalo et al, 2017). However, there is no previous study on the application of castor bean (Ricinus communis) and Leptadenia pyrotechnica (L. pyrotechnica) stems for pulp and paper production.…”

The suitability of the stems from two Sudanese dicotyledonous annual plants, namely castor bean (Ricinus communis) and Leptadenia pyrotechnica (L. pyrotechnica) were investigated for pulp and papermaking. Chemical compositions, elemental analysis, fi ber dimensions, paper physical properties and morphology revealed a relatively high α-cellulose content (46.2 and 44.3 %) and low lignin (19.7 and 21.7 %) in the stems of castor bean and L. pyrotechnica, respectively. The average fi ber length of castor bean and L. pyrotechnica is 0.80 and 0.70 mm with fi ber width of 16.30 μm and 18.20 μm, respectively, which makes them acceptable candidates. Soda-AQ pulping of castor bean stem led to a higher pulp yield of 43.2 % at kappa number 18.2 compared to 40.3 % at kappa 20.3 for L. pyrotechnica. This yield is less than that obtained for wood plants and similar to that observed for annual plants. Paper handsheets produced from castor bean showed better mechanical properties than L. pyrotechnica. SEM images indicated that the produced papers were quite homogeneous, compact, closely packed, and well assembled.

“…However, the value for adjusted R 2 is close enough to R 2 suggesting that the insignificant term does not have much effect on the fitted model ( Mathews, 2005 ). Also, the insignificant lack-of-fit further uphold the adequacy of the fitted model as agreed by Wutisatwongkul et al. (2016) .…”
