“…dead biomass was higher than those obtained for U. prolifera, 19.4% α-cellulose, and 14.4% hemicellulose (Li et al 2016), or U. pertusa Kjellmann, with 6.7% cellulose and 16.8% hemicellulose (Choi et al 2013). Chao et al 1999Sharma et al 2018Jiménez et al 2007 The low level of Klason-positive (acid insoluble) compounds detected was remarkable in comparison with agricultural residues or wood sources, which are usually around 20% to 30% in lignin (Jiménez et al 2008), and very similar to the amounts reported for U. prolifera, 9.4% (Li et al 2016), or U. reticulata (Yoza and Masutani 2013). While Li et al (2016) referred to the acid insoluble material as lignin, it is unlikely that algae could contain such high amounts of that heteropolymer, as they generally lack lignified cell walls (Martone et al 2009).…”

“…The EBE content is very low in typical raw materials for papermaking such as Eucalyptus globulus or Pine pinaster (1.2% and 2.6%, respectively; Jiménez et al 2007), and the values found for this macroalga (3.8% ± 1.1%) were close to those in wood. In contrast, HWS and 1% SS were much higher than those of wood and woody stems (Jiménez et al 2007), but similar to those of certain grasses (Sharma et al 2018). This was probably due to the starch fraction (Mukherjee and Keshri 2019).…”

“…While Li et al (2016) referred to the acid insoluble material as lignin, it is unlikely that algae could contain such high amounts of that heteropolymer, as they generally lack lignified cell walls (Martone et al 2009). In any case, the low amount of hydrolysis-resistant compound makes Ulva a structurally fragile material (Lee et al 2014) and therefore easily degradable during pulping, requiring much less energy and alkali charge than softwood, and less than hardwoods and common agricultural residues (Jimenez et al 2008;Sharma et al 2018). Table 3 shows the values of the properties of the handsheets obtained after alkaline and hydrogen peroxide treatments and refining of the algal biomass.…”

The large amount of cellulose found in Ulva sp. and its low percentage of lignin-like compounds make it an interesting raw material for partially substituting wood pulp to produce pulp and paper. This work shows the suitability of mild chemical treatments for papermaking using residual biomass from this green seaweed, harvested on the beaches, in order to give it added value. A chemical characterization was used to determine ethanol-benzene, hot water, and 1% soda extractives, ash content, holocellulose, α-cellulose, and acid-insoluble material. Cellulose extraction was performed with low proportions of soda and hydrogen peroxide, and it was subjected to a refining step. A design of experiments was used to explain the influence of soda (6%, 8%, and 10%) and hydrogen peroxide (2%, 4%, and 6%) based on oven-dry weight, plus refining (1000 PFI revolutions, 3000 PFI revolutions, and 5000 PFI revolutions). The results showed that to attain good paper strength, it is advisable to operate at maximum alkali charge, minimum peroxide concentration, and refine to a high degree.

“…With the same purpose, government bodies devote economic and human resources to research into alternative raw materials to conventional ones. For these reasons, a large number of studies on the use of non-woody materials, including agriculture residues and vegetables as alternative source for cellulosic pulp production, have emerged in recent years [1,[7][8][9][10][11][12][13][14].…”

The main source of cellulosic fibre used for pulp and paper production comes from wood, while non-wood fibres are used to a lesser extent. However, a renewed interest exists in the use of non-woody raw materials due to their abundance as source of low-cost fibres and because they are sometimes the only exploitable source of fibres in certain geographical areas, mainly in developing countries. Moreover, the great variety of characteristics, fibre dimensions and chemical composition of these alternative raw materials give them a great potential to produce different types of papers. On the other hand, the pulp and paper industry is an excellent starting point for the development of lignocellulosic biorefineries, possessing the necessary technology and infrastructure as well as extensive experience in lignocellulosic biomass transformation. Since its beginnings, the pulp and paper industry has been practicing certain aspects of the biorefinery concept, generating the energy necessary for the production of cellulosic pulp from the combustion of lignocellulosic waste and black liquors, recovering the chemical reagents used and generating high value-added products (e.g. tall oil) together with cellulosic pulp. However, the evolution of the pulp and paper industry to a lignocellulosic biorefinery requires technological innovations to make bioenergy and new bioproducts available alongside traditional products.

The hydrotropic pulping of crushed straw of Miscanthus sacchariflorus Andersson to produce pulp was studied herein. A concentrated sodium benzoate solution was used as the reagent. Established regularities of the pulping temperature and time effects on delignification quality attributes such as pulp yield and residual lignin content in the pulp. The generalized arithmetic-mean optimization parameter enabled hydrotropic pulping optimum conditions to be identified to obtain hard pulp fit. Experimentally displayed the possibility of using cellulose for the manufacture of special paper grades
