“…It has to be mentioned however, that a much higher yield of hardwood pulps can be achieved by trees older than those we tested in our study [52]. When considering yields and characteristics of cellulosic pulps obtained from multiple softwood and hardwood species, along with fast growing grasses in Poland [24], the yield of cellulosic pulp from aspen clones obtained in the present study confirms their high suitability for pulp production. In comparison, the only alternatives for hybrid aspen pulp in Poland appear to comprise pulps obtained from silver birch (Betula pendula Roth.)…”

Research Highlights: This research provides a firm basis for understanding the improved aspen hybrid performance that aims at facilitating optimal clone selection for industrial application. Background and Objectives: Rapid growth and wood properties make aspen (Populus tremula L.) suitable for the production of pulp and paper. We assessed the potential of tree improvement through hybridization to enhance aspen productivity in northern Poland, and investigated the effects of Populus tremula hybridization with Populus tremuloides Michaux and Populus alba L. on the growth and cellulosic pulp properties for papermaking purposes. Materials and Methods: A common garden trial was utilized that included 15 hybrid aspen clones of P. tremula × P. tremuloides, four of P. tremula × P. alba, and one, previously tested P. tremula clone. Clones of P. tremula, plus trees from wild populations, were used as a reference. Tree height and diameter at breast height (DBH) were measured after growing seasons four through seven. At seven years of age, the three clones representing all species combinations were harvested, and their cellulosic pulp properties and paper sheet characteristics were assessed. Results: The clones from wild populations exhibited the poorest growth. In contrast, the clone ‘Wä 13′ (P. tremula × P. tremuloides) demonstrated the highest DBH, height, volume production, and mean annual increment (MAI) (25.4 m3 ha−1 year−1). The MAI ratio calculated for interspecific crosses ranged from 1.35- to 1.42-fold, higher than that for the P. tremula. Chemical properties of pulp, fiber morphology, and the physical properties of paper sheets were more desirable for interspecific hybrid clones than those for the pure P. tremula clone. Conclusions: The results indicated that plantations of hybrid aspen may constitute an important additional source of wood for pulp and paper products in Poland. Our findings further suggested that the standard rotation of these trees may be reduced from 40 to 20 years, increasing overall biomass yield and enhancing atmospheric carbon sequestration.

“…Corresponding results were obtained for lignin content which varied from 1.1 up to 2.2%. In general, the pulps derived from the grasses were characterized by the significantly lower values of the Kappa number, as compared to the reported hardwood and softwood pulps, which were delignified under the same conditions [24,37,38]. It means that this material is susceptible to delignification using the kraft method.…”

This study showed that kraft cellulosic pulps from Miscanthus giganetus JM Greef and Deuter ex Hodk. and Renvoize, sweet sorghum and 5 other fast growing grasses may be easily enzymatically converted to glucose-rich sugar feedstocks. The scientific goal of the paper was to assess and compare the potential yield of hydrolysis and verify whether these grasses may be a source of sugars for fermentation processes. Kraft pulping was used as a pretreatment method and hydrolysis of the pulps was conducted using a commercial multienzyme preparation containing cellulases and xylanases at initial substrate concentrations of 0.476, 3.88 and 7.46% w/v, and 3 different enzyme loadings. Results showed that tall wheatgrass, striped tuber oat grass, tall fescue and smooth bromegrass may be efficiently converted to sugar feedstocks for biotechnology application, but that the simple reducing sugars yield is lower than for wood, due to lower cellulose content.

“…While the fiber diameter of horse grass with 30min and 90min cooking time was decreasing and later increased with cooking time, while 60min increases and later decreased. However, the average lengths and diameter of horse grass sample were generally in the range expected of grasses, nonwood materials and some wood species [13,14].…”

The delignification of horse grass (HG) was carried out using methanol and water (organosolv pulping); varying the cooking conditions at 30min, 60min and 90min with ratios: 1:1, 1:2 and 1:3, Methanol-water, cooked in autoclave at 1050C. The pulp obtained were selected and macerated in equal volume of glacial acetic acid (ethanoic acid) and hydrogen peroxide (1:1) at a temperature 1000C, to investigate the fiber length; fiber diameter; lumen with their derived indices and paper strength properties was determined according to TAPPI standard methods, T 494 om-96. The best fiber length of 3.21mm, tear index 31.43 mN.m2/g, tensile index 97.79Nm/g and bulk index 5.15 kPa.m2/g was obtained at 1:3 methanol: H2O at 105°C with cooking time of 60 min. Therefore, it was established that high quality papers of different grades can be produced from horse grass with acceptable strength properties using low concentration of methanol/water pulping with moderate time at boiling temperature. The research concluded that methanol-water was excellently good for pulping of horse grass fibers. The above results showed that horse grass is a good alternative sources of fibers to produce pulp and paper.
