“…As shown in Table 6, E. crassipes fibers contained a high proportion of fines (47.8%), compared with Pinus douglasiana kraft pulp (Rutiaga-Quiñones et al 1998), which has a long fibers retention of 87.1% in the 30 mesh. A high content of fines is also reported in cellulosic pulp of Cymbopogon winterianus (citronella grass) (Sharma et al 2020). The high fines in E. crassipes is related to its structural fine elements, such as parenchyma and aerenchyma cells (Mahmood et al 2005).…”

Eichhornia crassipes (water hyacinth) was pulped by means of a kraft pulping process with reagent loads of 10 and 20% on a dry matter basis to determine yield, rejects, kappa number, and ash. Fiber classification, brightness, opacity, and viscosity were measured in the brown pulp. Bleaching was performed by means of an O1O2D1(PO)D2HD3 sequence. Yield, kappa number, pH, ash, brightness, opacity, and viscosity were evaluated in the bleached pulp. Finally, a microanalysis of inorganic elements was carried out in both the bleached and unbleached pulp ash. The highest kraft pulp yield was 26.4%, with a 10% reagent load at 120 °C and 30 minutes cooking. It was determined that E. crassipes cellulosic pulp contains large amounts of fines. Results of the bleaching sequence indicate low brightness (58.0 %) and low viscosity (6.43 cP). The most abundant inorganic elements in the ash of both bleached and unbleached pulp were Ca, Mg, P, and Si. These results suggest that E. crassipes biomass might complement cellulosic fibers in pulping processes of low yield, such as the wood fibers used to produce handmade paper.

“…Fiber characteristics, mainly morphology and anatomy, have a great impact on the strength properties of the paper sheet (SHARMA et al, 2020b). The proportions of fibers in Acacia mearnsii woods from SPA and CPA were 74 and 67%, respectively, being considered high (CHOWDHURY et al, 2013), indicating that these woods would produce pulps with high yield.…”

“…These results are close to those found by SEGURA (2012) and MARCHIORI (1990) for fiber lengths of Acaciamearnsii, i.e., 0.94 mm and from 0.95 to 1.52 mm, respectively. The fiber length influences the tensile strength, tear strength, formation and uniformity of the paper sheet (SHARMA et al, 2020b).…”

The growing worldwide demand in the pulp market has fostered research that evaluates alternative fiber sources with specific characteristics that attend the needs of the consumer market, with a view to add value to the final product and reduce production costs. Acacia mearnsii De Wild wood is a by-product of the extraction of tannin from the trunk bark, used for firewood, charcoal and pellets. However, its wood is still poorly studied, especially its anatomical characteristics, which can provide important information about its industrial potential. This study evaluated the anatomical characteristics of Acacia mearnsii wood for the production of pulp and paper. Ten trees at approximately seven years old were cut down, five from the seed production area (SPA) and five from the clonal population area (CPA). From each tree, one trunk disc was sectioned at the diameter at breast height (DBH), resulting in 10 (ten) wood samples. From each disc, a sapwood specimen was made oriented in the tangential longitudinal, radial longitudinal and transversal planes, for later obtaining the anatomical cuts and the macerates. The anatomical description of the wood followed the recommendations of the International Association of Wood Anatomists-IAWA. From the dimensions of the fibers, their quality evaluation ratios for the production of pulp and paper were calculated. Results obtained from the anatomical characterization allowed to conclude that the Acacia mearnsii woods from SPA and CPA are indicated as a source of raw material for the pulp and paper production.
