Abstract:
In this paper, the bagasse wet-stored with hypochlorite (H) bleaching waste-water which was the original waste liquid from H bleaching process of bagasse, was cooked with alkali-oxygen and its pulping effect was studied. The results showed that the proper treatment time of wet storage with H bleaching waste-water was 12 days, the pulping properties were as follows: screened pulp yield 62.9%, kappa number 15.4, viscosity 802 mL/g, and brightness 58.8 %ISO. The strength properties of pulp were as follows: tensile index 65.6 N•m/g, tear index 5.86 mN•m2/g, burst index 3.83 kPa•m2/g and folding endurance 302 times. In addition, the pulping properties of bagasse wet-stored with H bleaching waste-water were similar to those of bagasse wet-stored with fresh water. Therefore, it can be concluded that the H bleaching waste-water could be used as spraying water for wet storage of bagasse. It was a new idea for saving fresh water in the pulping and papermaking industry.

Abstract:
Ordinary kraft pulping of bagasse was adjusted by utilizing green liquor at the laboratory and research of Misr-Edfu Pulp, Writing and Printing Paper in a small pilot batch digester (Edfu, Aswan, Egypt) as an environmentally friendly method. Bagasse pulp was produced with and without green liquor, and the physical and mechanical properties of unbleached bagasse were assessed. The parameter states of cooking were completed utilizing antacid substance charge from 10% to 13%, cooking temperature from 160 to 170 °C, cooking time from 20 to 50 min, and solid to liquor ratio of 7:1 that was steady in all preliminaries. The results demonstrated the exploratory idea that green liquor can provide critical pulping advantages in comparison with customary kraft pulping. Screened pulp yield improved 2.6%, rejects content decreased 0.9%, kappa number was reduced by 26.9%, and brightness was increased by 3%. There also was improved mechanical quality of bagasse pulp: increases of 14.3% (tensile index), 8.7% (tear index record), 4.6% (burst index), and 15.4% (double fold number) were observed compared with conventional kraft pulping. This process also saved money related to the expense of depleted vitality, lime consumed during causticizing process, and upkeep of the causticizing plant.

Abstract:
In this paper, the process of cellulase pretreatment before alkali-oxygen pulping of bagasse was studied. The effect of cellulase pretreatment on subsequent pulping was also researched. The results showed that some small-sized components and sugars dissolved into the effluent in the process of cellulase pretreatment. UV spectroscopy showed that there was no significant lignin content in the pretreatment effluent.It was also found that pulping properties were promoted when the cellulase dosage was 2 ECU/g pulp, in that under the same cooking conditions, pulp kappa number was decreased by 1.3 and pulp brightness was increased by 2.5 %ISO, while the viscosity of pulp also increased slightly. Moreover, the tensile index, tear index and folding endurance were increased by 8%, 7% and 30%, respectively, but burst index showed no significant change. The above results illustrated that cellulase pretreatment was only beneficial to the dissolution of sugars and fine components from bagasse and it was an effective method of promoting alkali-oxygen pulping of bagasse.

In this paper, the effect of residual chlorine of hypochlorite (H) on high yield pulping with H2O2/CoSO4of wet stored bagasse was studied. Compared with control sample, the pulp of the bagasse wetstored with H or Ho (without residual chlorine) bleaching waste water had better pulping yield and strength, but the pulp optical property was lost seriously. If it had no requirement on the brightness, the wet storage with H or Ho bleaching waste water was a good method to improve the pulp strength and save clean water. In addition, the wet storage of bagasse using the H bleaching waste water without residual chlorine, the pulping properties was more stable than that of the wet storage using H bleaching waste water with residual chlorine. To the wetstorage with Ho bleaching waste water, the ideal treatment time was 16day.

Abstract:
In the horticultural industry, upon main products obtaining, the formation of the following secondary raw materials and production wastes: pulping,bagasse, tomato seeds, fruit seeds, vegetable peelings, etc. is concomitant. At the same time, the amount of secondary raw materials formed during fruit and vegetable raw materials processing varies from 5 to 85% of the initial raw materials mass going for processing, of which an average of 30% is sent to food products for food processing. The aim of the work was to study the possibility of bagasse using of direct extraction beet juice production in vegetable paste technology. To facilitate the process of bagasse pulping, pretreated with microwave heating, starch syrup, allowing to reduce the vegetable mass viscosity was proposed to use. As a result of research, it was found that the introduction of starch syrup in the bagasse in the amount of 10, 20 and 30%, along with an increase in the heating temperature, varying from 25 to 60, reduces the effective viscosity obtained after bagasse paste pulping. With an increase in the starch syrup dosage, an increase in the mass fraction of dry substances in beet paste and its liquefaction degree was observed as well. So, at a dosage of 10%, the liquefaction degree was 24.7%, at 20% - 45.1%, at 30% - 60.7%. Thus, the use of starch syrup in the production of beet paste from the bagasse of direct-pressed juice production makes it possible to adjust the vegetable mass viscosity purposefully, creating better conditions for subsequent technological operations. .

Abstract:
The perceptions of absolute scarcity of forest based cellulosic materials and high anticipated demand for paper appear to have been responsible for the policy emphasis on unconventional materials for paper and newsprint making in India. Among the unconventional materials, bagasse has been emphasized through fiscal incentives including excise duty exemptions. Based on a study of seven bagasse based paper and newsprint units, Tirath Gupta and Vinod Ahuja show that enhancing residual bagasse through drying it before firing the boilers and using that material for pulping would be more desirable compared to generating surplus bagasse by installing coal fired boilers at sugar mills. The most desirable and sustainable solution in the long- run, according to them, would be to integrate the production processes of paper and cellulosic materials.

Abstract:
Abstract Alkaline sulfite/anthraquinone (AS/AQ) pulping and totally chlorine free (TCF) bleaching of bagasse was investigated. Depithed and wet cleaned bagasse was collected from the Pars Paper Company in southern Iran, dried and then pulped. The active alkali charge was chosen between 16 and 20% on oven-dry bagasse and the alkali ratio, Na2SO3/NaOH, was varied from 30/70 to 70/30. The AQ dose was kept constant. While keeping a constant cooking time at maximum temperature for 60 min, the maximum temperature was varied between 155 and 165°C. For bleaching, a pulp with a kappa number of 8.5 was produced under the following conditions: 18% active alkali, alkali ratio 30/70, 60 min cooking at 155°C. TCF bleaching was performed with oxygen and hydrogen peroxide. Oxygen delignification (O) with an alkali charge of 2% NaOH resulted in 50% degree of delignification. A brightness of 80% ISO was achieved with a chelating treatment (Q) and a subsequent oxygen reinforced peroxide bleaching stage (OP) under drastic conditions (4% H2O2, 2.75% NaOH, 90 min at 98°C). With an additional peroxide bleaching stage charging 2% H2O2, the brightness could be further improved to 83.5% ISO. Bleaching led to only small losses in tensile and burst strength at unchanged tear strength. Short beating in a Jokro mill was sufficient to attain good pulp strength. The results indicate that AS/AQ pulping and TCF bleaching can be successfully applied to bagasse to produce pulp for writing and printing paper.

Abstract:
The main goal of this study was to evaluate the potential of depithed bagasse for the production of printing and writing paper. Industrial whole bagasse was separated into two fractions: pith and depithed bagasse. The depithed bagasse was cooked by the soda process to two different degrees of delignification. The resulting pulps were fully bleached by the O-D*-(EP)-D sequence and characterized for their beatability, drainability, and physical-mechanical properties. Bleached soda pulps cooked to kappa 17.5 and 10.8 showed similar refinability and resistance to drainage, but the strength properties (tensile, burst, and tear) were slightly higher for the kappa 17.5 pulp at beating energy consumptions in the range of 2-7 W•h. We concluded that both pulps from depithed sugar cane bagasse would be suitable for the production of printing and writing paper grade pulps, but the higher kappa pulp is more economically attractive given its higher pulping yield, without significantly increasing the bleaching chemical demand.

Abstract:
Abstract This study aims to investigate the potential of using lignin sourced from South African black liquor as a total phenol substitute in phenol-formaldehyde resins (PFRs), with a particular focus on bonding strength and curing properties. Four South African pulping-based lignins were used to synthesize these lignin-phenol formaldehyde resins (LPF100 resins), namely Eucalyptus Kraft lignin, Pine Kraft lignin, Bagasse Soda lignin, and Bagasse Steam Exploded lignin. Fourier-transform infrared spectroscopy, thermogravimetric analysis, and differential scanning calorimetry were used to determine structural and curing properties. These resins were then used directly (unmodified) as adhesives to test shear bonding strength (R0 LPF100 adhesives). To improve the bonding properties of the unmodified LPF100 adhesives, the LPF100 resins were modified via the addition of a crosslinker (hexamine) as well as a hardener (either glyoxal, R1, or epichlorohydrin, R2). All R0 LPF100 adhesives fell below the GB/T 17657-2013 plywood standard of ≥0.7 MPa, with the Bagasse Soda LPF100 adhesive recording the highest bonding performance of 0.5 MPa, and the lowest curing temperature of 68°C. From the modified adhesives, the best performing were the Pine Kraft (R1) and the Eucalyptus Kraft (R2) LPF100 adhesives, recording 1.4 and 1.3 MPa, respectively. The curing temperatures of both these resins were 71°C and 80°C, respectively. Ultimately, the results of this study indicated that favorable adhesive properties may be obtained with the use of South African pulping-based lignins as a 100 percent phenol substitute in PFRs.

Abstract:
Wood is not sufficient in many countries to meet the rise demand for paper and pulp. In recent years, a lot of researches have been done to find a new, non-wood raw material for paper production especially using agricultural waste. Agriculture industry is one of the main industries in Malaysia which has generated a large amount of waste every year such as banana stem, rice hull, sugarcane bagasse and wheat straw. These are regarded as abundant, inexpensive and readily available natural resources for pulping industry. The purpose of this paper is to study of the pulping potentialities of banana stems which are growing in Malaysia. In this research the banana stem is used as raw material in the pulping process for the purpose of producing cellulose as pulp. The chemical pulping method which is used in the study is soda pulping, where NaOH is the main chemical substance used in cooking and with anthroquinone as the additive. Temperature, residence time and dosage of chemical were the parameters to be manipulated in this non-wood chemical pulping process to get an optimum condition for pulping. A 3 litre batch reactor was used in this non-wood chemical pulping process. The concentration of NaOH used was varied from 10 – 45 % and cooking temperature was varied from 100 – 200 °C. The ratio of solid to liquid is set at 1:8 and also the cooking period was varied from 30 – 210 minutes. The result shows that the optimum yield of pulp from this study is at 20 % w/w NaOH, cooking at 160 °C with 120 minutes. The yield of pulp is around 30 %. The cellulose content in the pulp produced is as high as 90 %.

Abstract:
Abstract Pulp-polylactic acid composites (PPCs) with monoethanolamine, alkaline sulfite-anthraquinone, unbleached and bleached soda bagasse pulps and polylactic acid (PLA) were successfully fabricated using twin-screw extrusion. The results were compared with bagasse flour-PLA composites (WPCs) as reference. The results indicated that the mechanical strengths of produced composites with pulp fibers were increased compared to the neat PLA and bagasse flour-PLA composites. Monoethanolamine and alkaline sulfite-anthraquinone fibers due to their surface chemical structure had a superior compatibility with PLA compared with other used bio-fibers which has been confirmed by SEM micrographs too. FTIR was used to investigate the effect of different chemical treatments on the bio-fibers. The results of XRD analysis showed that the crystallinity of PPCs was substantially improved by incorporation with pulp fibers compared to WPCs composites. The water absorption of the PPCs is different due to using the diverse bio-fibers. According to DMA analysis, the tan delta was substantially decreased when PLA was reinforced by different bio-fibers. The biodegradation of green composites were characterized and the results showed that the biodegradability of the PLA was increased due to addition of bagasse pulp biofibers.

Abstract:
Bagasse pulp waste (BPW) is a material generated from the depithing of sugarcane bagasse stems prior to pulping. It was subjected to a modified oxygen delignification or ammonia catalytic steam explosion (AE) pretreatment for delignification and retaining carbohydrates of raw materials, followed by simultaneous saccharification and co-fermentation (SSCF) to ethanol. Based on this process, an environmentally sustainable two-stage process for lignin purification was employed to obtain nontoxic “green lignin”. The results indicated that both pretreatment methods, particularly AE, had outstanding performance in the SSCF process. The highest ethanol yield (based on dry matter of BPW), 67.5% for the AE pretreatment, was obtained from the SSCF procedure at 8% (w/v) solids loading. Furthermore, the obtained lignin products from this process possessed better structural integrity.

Abstract:
Abstract Effective utilization of fibrous materials plays a major role in techno-economic viability of the resources. Sunflower stalk (SS) as one of highest bio-fibrous waste was assessed respect to fiber features in biorefinery approach. The lumen diameter, wall thickness and fiber length were measured as (∼12 µm), (5.25 µm) and (1.58 mm), respectively. The wider lumen diameter makes its suitable for chemical treatments and purification. The applied Pulping conditions decreased the fiber length and wall thickness, with the least reduction by soda-anthraquinone. Derived indices involved rigidity and flexibility coefficients, aspect and Runkel ratios, solid and Luce’s shape factors were also calculated based on the measured values. The aspect ratio (77.5) put SS fibers as very good resources for lignocellulosic products and composites. The flexibility coefficient (57) belongs to the elastic category and was not altered by pulping. The Runkel ratio was lesser than 1 (>0.9) but decreased by the pulping, to some extent. The Luceʼs shape factor was nearly calculated 0.5, near to the bagasse and eucalyptus species. Solid factor (0.17) and rigidity coefficient (0.51) were considered to be good fiber resource. Totally due to the SS fiber characteristics, the agricultural waste suitability for value adding bio-based production could be reported.

Abstract:
To recommend the beneficial effect of the pulping process on enhancing agro-wastes as precursors for the production of high-performance activated carbons (ACs), different pulping methods (alkali, sulfite and neutral sulfite) were applied on two available Egyptian agriculture by-products (rice straw and sugar cane bagasse), using the one-step pyrolysis method and H 3 PO 4 activating agent. The adsorption performance of the different prepared ACs was evaluated in terms of Iodine Numbers and their sorption properties for removing the methylene blue (MB) from aqueous solutions. The corresponding sorption processes were also analysed using Lagergren first order, pseudo-second order and intraparticle diffusion models. Data revealed that the applied pulping conditions were effective for removing the non-cellulosic constituents of agro-residues. This was demonstrated by the hydrogen/carbon and oxygen/carbon ratios, thermal stability and IR-measurements of the final pulps. These data were effective on the particular sorption properties of RS and SCB-based ACs. Interestingly, the pulping process is a profound modification of the SCB-based fibres, on which it induced a clear increase of the specific surface areas of the corresponding ACs even though they had an impact on the sorption of MB and iodine. These values are superior to the reported data on agro-based ACs with H 3 PO 4 activators. Pulping processes therefore play a dual role in the sorption properties of ACs. The first important role is the impact on the specific surface areas and the second impact is a profound modification of the surface chemistry of the ACs. Therefore, SCB-based ACs can be seen as an economical breakthrough product, and an alternative to the high-cost commercial ACs for the purification of industrial wastewaters.
