Full textAbstract:
Fast-growing biomass, such as bamboo, has the potential to serve an important future role in the pulp and paper industry with potential to both lower resource costs and improve a product’s sustainability. Moso bamboo is particularly interesting due to its fast growth and size, which allows it to be handled and chipped similarly to wood resources. In this study, we will share results of the chip preparation, kraft cooking, and ECF bleaching of this bamboo species and compare its pulpability, bleachability, and physical properties to a fast growing hybrid poplar tree. Results indicate that the bamboo chips cooked and bleached similarly to the poplar hardwood, allowing for co-cooking. The resulting pulps had superior tensile properties at low refining, but did have higher fines that lowered drainability as measured by Canadian Standard Freeness. The bamboo fiber morphology was also measured, indicating the fiber to have length weighted average fiber lengths and coarseness values to be greater than the poplar wood studied, which should allow this material to be used in many paper grades.

Bamboo is one of the world’s fastest growing feedstocks and represents a promising nonwood resource that can be utilized in the pulp and paper industry. The timber varieties offer low feedstock costs, can be processed similarly to trees from a logistics standpoint, and have useful fiber properties for papermaking. Plantations have not yet been established due to propagation costs, limiting adoption of bamboo as a pulp feedstock to smaller pulp mills primarily in China, where there are native forests. Recent advances in micropropagation may allow lower establishment costs, but gradual introduction into the supply chain will be required. One concept is to gradually include bamboo feedstock into an established pulp mill as plantations are established, using co-cooking with a wood species. Previous work has shown that bamboo cooks fairly easily using the kraft process with conditions similar to hardwood species.

This study aims to see the potential of bamboo as a new raw material for the Indonesian pulp industry, specifically for the manufacture of pulp products, because in Indonesia, the import value for dissolving is still high, and the raw materials used still use wood plants. This study consists of three stages: the pre-hydrolysis stage using water, the cooking stage with the kraft pulping method, and bleaching using the elemental chlorine-free (ECF) method. Bamboo flakes that run into the pre-hydrolysis process decreased the Kappa Number value of pulp produced, which ranges from 4.63% - 14.52% compared to bamboo flakes that do not run into the pre-hydrolysis process. The brightness increase to 0.844% - 2.96% compared to bamboo flakes that do not run into the process of pre-hydrolysis. For pulp products, the value of Alpha Cellulose obtained is around 89.18% - 90.32%.

Bamboo is one of the world’s fastest growing feedstocks. It is a promising nonwood resource that can be used in the pulp and paper industry. Among more than 1200 species of bamboo, the timber varieties can be processed much like trees, allowing current pulp mill logistical systems to be used. Bamboo can be difficult to pulp because of its high silica content, which creates issues for black liquor recovery. This study compares two methods of reducing the silica content of a common species of timber bamboo. Specifically, the dermis layer of Moso bamboo (Phyllostachys edulis) was removed through mechanical treatment and then chipped. The same species was also chipped without treatment. The two chipped materials were then alkali extracted and subjected to kraft pulping experiments. The pulps were bleached with an OD0(EP)D1 sequence. The material was then refined and formed into handsheets. The results indicate that 80% of the silica could be removed from the bamboo material through a combination of dermal mechanical treatment and caustic chip extraction. Caustic chip extraction removed a significant portion of hemicellulose materials, which in turn lowered cooking yields but had minimal effect on pulp properties.

Abstract The potential use of sago pith waste, bamboo, and water hyacinth based on the characteristics of raw materials to make liner paper were studied. The analysis conducted covered the analysis of physical characteristics, chemical components, morphology (SEM), functional groups (FTIR), and crystallinity (XRD). The pulp from the three kinds of fiber was molded into paper with a certain formulation. The parameters of pulp and paper observed covered the alkaline consumption, Kappa number, pulp yield, and paper physical characteristics (grammage, bursting strength, Ring Crush Test/RCT, water content, and water absorption). The chosen paper was the paper whose characteristics resembled the quality parameter of liner paper used by the paper industry and the standard in accordance with the Indonesia’s National Standard (SNI) 14-0095-1996. The microscope images showed that the three said raw materials have long fibers: sago pith waste and water hyacinth has fibers measuring respectively 1.89±0.90 and 2.07±0.39 mm, resembling hard wood, whereas bamboos have longer fibers measuring 4.61±0.72 mm, resembling soft wood. Bamboos have the best fiber composition and characteristics for pulp and liner paper. The two paper formulas that meet the criteria for liner paper are bamboo and bamboo+water hyacinth.

Fiber morphology of 3 species of bamboo namely Bambusa vulgaris, Gigantochloa levis, and Gigantochloa scortechinii at age of 1, 3, and 5 years, was evaluated. It shows that different species of bamboo have different properties in terms of their fiber morphology that consist of fiber length, fiber diameter, and lumen diameter. Fiber diameter, fiber length, and cell wall thickness increased with the increasing of the bamboo age but the lumen diameter decreased when the bamboo gets older. G. levis at age 1 to 3 and G. scortechinii at age 1 have high potential to be the raw materials for the pulp and paper industry.

Full textAbstract:
Summary The pulp and paper industry in China has been growing rapidly as the nation's population and economy have grown. As a result, there has been a huge demand for pulp and paper raw materials. China has a long tradition for using non-wood raw materials for pulp and paper due to its limited forest resources and rich supply of agricultural residues and non-wood plants. Agricultural residues, such as rice straw and wheat straw, are traditional raw materials for China's paper industry. Massive plantation of bamboo provides an increasingly important source of raw material for pulp and paper. Problems with non-wood fiber include collection and transportation, storage and handling, washing, bleaching, papermaking, and chemical recovery. Small mills, primary users of non-wood fiber, are typically deficient in pollution control and subject to government closure. This paper reviews non-wood fibers commonly used in China's pulp and paper industry. By increased knowledge of use of non-wood fibers, wood suppliers can plan for access to the growing Chinese market.

The environment is the basis for the living and development of the human, and eco-innovation is the key driver of new economic growth. However, for some underdeveloped regions in China, it is still a challenge for the local government to get a balance between the goals of economic and environment. The paper selects the pulp and paper industry, which creates tremendous pollution to the environment and is closely related to the daily life. According to the particular characteristics of pulp and paper industry in Sichuan Province, the industry of pulp and paper of bamboo is redesigned to improve the local ecosystem, while increasing the income of local farmers. From the perspective of game theory, the relationships between the government, the enterprise, and the farmers are analyzed. The result shows that government increases the subsidy and penalty to the enterprise, which can increase the investment in eco-innovation, enhancing the competitiveness of enterprises and raising the income of farmers. Moreover, it can also improve the ecologically fragile areas by the utilization of bamboo park. In addition, in this paper, a system dynamics model is proposed to explore the impact of different policies on the environment. The results show that increasing the subsidy is a more efficient way to protect the environment, and is one of the important drivers to eco-innovation in some underdeveloped regions in China.

This research aimed to analyze the change in chemical composition of the betung bamboo (Dendrocalamus asper) strands after alkali immersion treatment under various immersion times. The bamboo culms were converted into strands with the target length, width, and thickness of 70, 25, and 0.5 mm, respectively. Strands were alkali immersion-treated with 1% NaOH solution for 1, 2, and 3 h. Preparation of powder for chemical component analysis refers to the Technical Association of the Pulp and Paper Industry (TAPPI) standard T 264 cm-07 regarding the preparation of wood test samples for chemical analysis. Structural and non-structural bamboo strand chemical components such as holocellulose, alpha-cellulose, hemicellulose, klason lignin, and extractives were analyzed. The results showed that alkali immersion treatment decreased the hemicellulose content from 21.55% before treatment to 20.30% after 3 h immersion. Thus, it changed the holocellulose and alpha-cellulose composition. Alkali immersion treatment also changed the extractive substances dissolved in cold water, hot water, 1% NaOH, and ethanol-benzene solution. The decrease in hemicellulose, molecular weight lignin, and extractive substances would be beneficial for bamboo-oriented strand board manufacture to improve strand adhesion, dimensional stability, mechanical properties, and durability against biological agents attack. Keywords: alkali immersion times, alkali immersion treatment, bamboo, chemical components, pre-treatment

Bamboo is a sustainable and environmentally friendly material that has the potential to improve the global decline of natural resources. Bamboo is very popular in the countryside of almost all Southeast countries, particularly in Vietnam. Its ability can replace some kinds of wood in decoration and household goods. Bamboo grows up rapidly and can be harvested within 3 to 5 years of planting, in the meanwhile, the harvesting time of other hardwood trees must be from 8 to 10 years or longer. The inherent characteristics of bamboo are lighter than other wood materials and have a value in social and environmental benefits. Its advances in manufacturing technology have created high-value products such as bamboo flooring and bamboo furniture that can substitute for wood flooring and wood furniture. According to the biology studies, the bamboo has the characteristics that can replace the natural wood, but the direction of development from the stage of cultivation to the stage of finished products has not been exploited thoroughly. The production of bamboo plywood will become a great potential for the bamboo plywood industry in Vietnam. Generally, the fabrication of bamboo plywood depends on the following processes such as cutting, grinding to powder or pulp, drying, and pressing processes. In cutting and grinding processes, the trivial remains of bamboo after use, shoots… can be chopped and ground to a powder that is dried and pressed into bamboo plywood by a specialized machine similar to the production of artificial wood particleboard (PB). Bamboo powder drying machine plays a very important role in the production process of bamboo plywood. The function of the machine is drying bamboo powder to get the technical required appropriate moisture before pressing it into the standard bamboo boards. This article presents a design of bamboo powder drying machine with simple structure, long life, medium productivity, and price suitable for medium and small scale production of the Vietnam market. The first bamboo powder drying machine that was manufactured in DCSElab and its products is considered to respond to the technical requirements of customers.

Full textAbstract:
In recent years, bamboo has been well exploited in the pulp and paper industry. Moso bamboo (Phyllostachys edulis (Carriere) J. Houzeau; hereafter M), originated from China with a long history of cultivation as the most abundant resource with the widest distribution area among bamboo plants in China. In this study, Moso bamboo (M) and nine bamboo varieties were selected in the bamboo germplasm resources storage bank of the Anhui Taiping Experimental Station of ICBR. The characteristics of their cell structures were compared, and the differences were analyzed from a genetic perspective. The results showed that M had the highest fiber cell length, fiber cell width, length, and parenchyma width, while GJ showed the lowest of these measurements [P. edulis ’Kikko-chiku’,G.H.Lai]. The fiber wall thickness of Q [P. edulis f. obliquinoda (Z.P.Wang et N.X.Ma) Ohrnberger] was the smallest, while its fiber lumen diameter was the highest in the group. The parenchyma wall thickness and parenchyma lumen diameter of Q were the smallest in the group. The fiber cells of M and Q had better flexibility, which is conducive to improving the tensile strength, break resistance, and folding resistance of paper made from these materials. SY and GJ may be more suitable for ornamental items because of their special appearances. The purpose of this study was to explore the genetic variation patterns of various cell structure indicators among Moso bamboo and its varieties, as well as to develop a strategy of bamboo growing and lumbering based on the local conditions, providing reference data for the utilization of non-woody forest resources.

Bamboo is a versatile product, including building materials, furniture, fencing, handicrafts, pulp and paper, edible shoots, and animal feed used in many countries. The first purpose of this study was to evaluate and group the applications and benefits of bamboo, the second is to compare the views of consumers and businessmen to find the expectation gap between them, the third is to find the correlation between the importance of bamboo applications with the perceived benefit of bamboo and finally apply the importance-performance analysis model to position the expected application and benefits of bamboo. The theory was developed taking in account three factors: the importance, the benefits of bamboo applications, and both consumers and businessmen. The data analysis was performed on a sample of 469 respondents divided into two parts 378 for consumers and 91 for businessmen conducted in Haiti. This study exhibited that the applications were formed two groups - High importance group with five applications represented 48.9 %; and the low importance group with 15 applications are represented 51.1% based in their frequency. Furthermore, the results indicated that the consumer's views were higher than businessman for the important applications of bamboo and the businessmen were higher than the consumers for the perceived benefits of bamboo because the consumers focus on the wants of application can be profitable for us and businessman focus on the benefit. The results showed a positive relationship between the importance of bamboo with the perceive benefits. The study found the most important application is (G) bamboo panels (wall room) from consumers because this application was with multiple purposes; and the fabrication and wood base in the industry from the businessmen. So we might say the applications bamboo was very important for the country according to the respondent’s responses and also the benefits for the businessmen. Therefore, if the country could embrace this alternative, it will be a great opportunity for the population.

Functional fabrics have gained attention as an environmentally-friendly synthesis route. In the current study, novelty bamboo pulp fabrics with thermal conductivity properties were prepared by coating the fabric with graphene and cellulose nanocrystal (G/CNC) solutions. The influences of G and CNC concentrations on properties of fabrics were studied. The viscosities of the G/CNC solutions increased with an increase of G contents. G had an obvious thickening effect. Furthermore, compounded fabrics with different G and CNC contents (GCBPFs) were prepared and extensively characterized in terms of thermal and mechanical properties, and morphology. The ultimate thermal conductivity, bursting strength, and tensile strength of the GCBPF were 0.136 W/m·K, 1.514 MPa, and 25.8 MPa, with 4 wt.% CNC and 3 wt.% G contents, respectively. The results demonstrated that the as-fabricated GCBPFs with favorable thermal conductivity could be applied as a novel fast cooling textile for the clothing industry.

The reactivity of salen complexes toward hydrogen peroxide has been long recognized. Co(salen) was tested as catalyst for the aqueous oxidation of a refractory lignin-carbohydrate complex (LCC) isolated from sweet bamboo (Dendrocalamushamiltonii) in the presence of hydrogen peroxide as oxidant. Co(salen) catalyzed the reaction of hydrogen peroxide with LCC. From the spectra analyses, lignin units in LCC were undergoing ring-opening, side chain oxidation, demethoxylation, ?-O-4 cleavage with Co(salen) catalytic oxidation. The degradation was also observed in the carbohydrate of LCC. The investigation on the refractory LCC degradation catalyzed by Co(salen) may be an important aspect for environmentally-oriented biomimetic bleaching in pulp and paper industry.

Full textAbstract:
Increasing the solids content of pulping black liquor burned in a furnace is a development trend of the alkali recovery system in the pulp and paper industry. However, the viscosity of kraft black liquor increases exponentially with an increase in solids content, especially in the case of non-wood pulping black liquor, such as bamboo. This brings great difficulties to the pulping system and atomization of black liquor at the splash-plate nozzle, which is a complete atomization unit constituted of a splash nozzle and a splash plate. To obtain instructive results for industry, a simulation of the atomization process was made using Fluent software for the bamboo kraft black liquor with solids contents of 70 wt% and 80 wt%, which flowed through splash nozzles with the diameter of 22 or 20 mm. The studies were conducted on the distribution of flow field in the nozzle and atomization region through changing the injection pressure and nozzle diameter. The variation of atomization characteristic parameters, such as liquid film thickness, and breakup length, were elucidated. The results reveal the relationship between spray atomization with injection pressure and nozzle diameter, which provides a theoretical basis for improving the concentration of black liquor entering alkali recovery in the future.

Bamboo pulping fabrics (BPFs), one of the most important textile materials for clothing industry, has many excellent characteristics such as soft, skin-friendly, and hygroscopic, etc., but some drawbacks especially mildewed, causing customers’ concerns. This experiment evaluated effects of two organic acids, acetic acid (AA) and citric acid (CA), as solvents for dissolving chitosan on the antibacterial properties of chitosan-treated BPFs with the intention of replacing AA with CA because previous research finding indicated the strong acid smelling of BPFs treated with chitosan dissolved in AA. Experimental results indicated that BPFs treated chitosan dissolved in CA had a significantly higher antibacterial rate than ones treated with chitosan dissolved in AA within each of five chitosan mass fraction levels investigated. Antibacterial rates of BPFs treated with chitosan dissolved in AA and CA increased as chitosan mass fraction increased, but increasing rates were different between BPFs treated with chitosan dissolved in AA and CA. No acid sour smell was detected for BPFs treated with chitosan dissolved in CA.

Paper is an excellent medium of expression and knowledge preservation and communication because of its writing, printing, and packaging abilities. It is a thin sheet or web-like structure made by a dilute suspension of cellulosic fibres. Handmade papermaking technology was mass accepted and considered a precious commodity before development of an industrialised wood- pulp based paper industry. This modern papermaking practice harms the environment as it uses enhanced natural resources (ample amount of water, trees as a primary source for wood pulp) and generates pollution due to release of harsh chemicals. This paper reviews the history and process of handmade paper manufacturing from past to present. Along with that, all the pillars of sustainability (environmental, economic, and social) in relation to the handmade paper industry are deep rooted since ancient times and very much relevant for the present era of sustainable development. Various kinds of cellulosic raw materials from plants (Paper mulberry, Kazo, Gampy, hemp, bamboo, banana, etc.) and other used materials (old rags, ropes, nets, newspapers etc.) with the chemical-free production process and products make this industry eco-friendly. Craft based, small scale and labour-intensive guild art gives it social strength; whereas an infinite product range having functional and decorative uses, as well as strong export potential of the industry gives it an economic strength. Due to the present need of sustainable production, waste minimisation, and circular economy, the handmade paper seems to very potential industry to recycle various kind of waste like weedy battles, textiles, tetra packs, currency, plastic etc. This paper is an attempt to review the journey of handmade papers, its recycling potential, various production processes, products, advantages and disadvantages of the industry from past to present.

Prior to the nitration process, both dissolving pulp of Beema bamboo and industrial undergo a pretreatment process using willey mill, the pulp then sieved and taken with a size less than 60 mesh. In the nitration process, the chemical composition used is formula 1 (HNO3: HNO3 Fumming: H2SO4 = 2.5: 1: 9.5), formula 2 (HNO3: HNO3 Fumming: H2SO4 = 3: 1: 7,5) and the formula 3 (HNO3: HNO3 Fumming: H2SO4 = 1: 1: 1,6). Result showed that dissolving pulp from Beema bamboo with third formula get the highest nitrogen content (12,97%). Fourier-transform infrared spectroscopy (FTIR) analysis showed that all of the nitrocellulose have nitro group and with burning test also proved that nitrocellulose can be rapidly burdened. However, the solubility of nitrocellulose in acetone and ethers-alcohols indicates that the distribution of nitrogen content in the nitration process is not meet the standard yet.
