“…The results for the chemical compounds of the raw materials ( Table 2 ) show that benzene–alcohol extracts, lignin, holocellulose, and ash content were 1.73–13.16%, 16.66–42.33%, 53.37–63.40%, and 1.66–6.73%, respectively. The holocellulose content in S. bicolor stalks was in accordance with the range of values reported in the literature: 71.0% [ 16 ], 67.2% [ 23 ], 68.0% from depithed extraction [ 85 ], 61.6% extracted with 1% NaOH [ 85 ], 69.0% from depithed extraction [ 86 ], and 61.6% extracted with 1% NaOH [ 86 ]. The average pulp yield from S. bicolor stalks was 45%, and the average kappa number was 14–18 when 16–20% sodium (NaOH) and a 1.5 h cooking time at 160 °C were used [ 12 ].…”

“…Several non-wood materials, such as flax plants, dhaincha ( Sesbania bispinosa ), jute stick ( Corchorus capsularis ), sugarcane bagasse, cotton stalk, rice straw, wheatgrass, smooth bromegrass, switchgrass ( Panicum virgatum ), Miscanthus giganteus , and bamboo, have been studied to assess their suitability for the production of pulp and paper [ 7 , 8 , 9 , 10 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. For example, sorghum stalks ( Sorghum bicolor ) can be used as an alternative source for pulp production.…”

“…Previous studies have focused on the properties of pulp and paper produced from Zea mays and S. bicolor stalks and have shown them to have promising values in terms of mechanical properties, such as the tensile index, burst index, tear index, burst index, and double fold number [ 15 , 16 , 22 , 23 , 24 , 25 ].…”

The main objective of this work was to evaluate pulp produced by kraft cooking for wood materials (WMT) (Bougainvillea spectabilis, Ficus altissima, and F. elastica) and non-wood materials (NWMT) (Sorghum bicolor and Zea mays stalks) and to study the fungal activity of handsheets treated with Melia azedarach heartwood extract (MAHE) solutions. Through the aforementioned analyses, the ideal cooking conditions were determined for each raw material based on the lignin percentage present. After cooking, pulp showed a decrease in the Kappa number produced from WMT, ranging from 16 to 17. This was in contrast with NWMT, which had Kappa numbers ranging from 31 to 35. A difference in the optical properties of the pulp produced from WMT was also observed (18 to 29%) compared with pulp produced from NWMT (32.66 to 35.35%). As for the evaluation of the mechanical properties, the tensile index of the pulp ranged from 30.5 to 40 N·m/g for WMT and from 44.33 to 47.43 N·m/g for NWMT; the tear index ranged from 1.66 to 2.55 mN·m2/g for WMT and from 4.75 to 5.87 mN·m2/g for NWMT; and the burst index ranged from 2.35 to 2.85 kPa·m2/g for WMT and from 3.92 to 4.76 kPa·m2/g for NWMT. Finally, the double fold number was 3 compared with that of pulp produced from pulp, which showed good values ranging from 36 to 55. In the SEM examination, sheets produced from treated handsheets with extract from MAHE showed no growth of Aspergillus fumigatus over paper discs manufactured from B. speclabilis pulp wood. Pulp paper produced from Z. mays and S. bicolor stalks was treated with 1% MAHE, while pulp paper from F. elastica was treated with 0.50% and 1% MAHE. With the addition of 0.5 or 1% MAHE, Fusarium culmorum showed no increase in growth over the paper manufactured from B. speclabilis, F. altissima, F. elastica and Zea mays pulps with visual inhibition zones found. There was almost no growth of S. solani in paper discs manufactured from pulps treated with 1% MAHE. This is probably due to the phytochemical compounds present in the extract. The HPLC analysis of MAHE identified p-hydroxybenzoic acid, caffeine, rutin, chlorogenic acid, benzoic acid, quinol, and quercetin as the main compounds, and these were present in concentrations of 3966.88, 1032.67, 834.13, 767.81, 660.64, 594.86, and 460.36 mg/Kg extract, respectively. Additionally, due to the importance of making paper from agricultural waste (stalks of S. bicolor and Z. mays), the development of sorghum and corn with high biomass is suggested.

“…Jiménez et al (1993) studied the application of sorghum stalks in pulp and papermaking and determined they had better properties than other agricultural residues, such as olive tree fellings, wheat straw, sunflower stalks, vine shoots, and cotton plant stalks. Gençer and Şahin (2015) identified conditions for producing pulp and paper from sorghum. Indeed, the length of sorghum stalks is sufficient to make them a viable alternative for pulp and paper production.…”

The suitability of specific Sudanese agrowastes, sorghum straw, bagasse, and their 50% blend, were investigated for pulp and papermaking initiatives. A chemical analysis of sorghum straw and bagasse revealed levels of cellulose, lignin, hemicellulose, and ash for sorghum straw and bagasse that signalled a suitable relation to traditional wood feedstocks for pulping and papermaking applications. Moreover, the pulp yield and viscosity of sorghum straw were lower and higher, respectively, compared with the bagasse and the blend. More specifically, the papers obtained from bagasse showed better physical properties (tensile strength, tearing index, bursting index, and folding) compared to those of sorghum straw and the blend. The surface morphologies of the papers were analysed using scanning electron microscopy (SEM), which showed that the fibres had a long, swollen, compact, and closely packed arrangement and were more homogeneous and well-blended for the bagasse compared with the pure sorghum straw and the 50% blend.
