Pulp Production

The pulp and paper industry is primarily dependent on fibrous wood for pulp and paper production. However, this over-dependence on fibrous wood poses serious environmental challenges such as the diminishing of the fibrous wood stocks, deforestation, emission of greenhouse gases, and global warming. Therefore, to mitigate these environmental challenges associated with its utilization for paper and pulp production, other sustainable raw material sources can also be considered for the production of paper and pulp. There are enormous benefits associated with the utilization of non-wood fibres as an alternative and sustainable raw materials source for the production of paper and pulp. These benefits have in the recent past prompted millers in China, India, Brazil, and the USA to consider the utilization of non-wood fibres in paper and pulp production. In Kenya, the pulp and paper industry is very much dependent on fibrous wood for production and the industry is yet to fully embrace the utilization of nonwood fibres for paper and pulp production. Further, the dependence on fibrous wood has contributed significantly to the decline of paper pulp and paper production, deforestation, and rise in paper importations due to insufficient raw material supplies. The importation of paper and pulp products has further led to the collapse of the paper industry in Kenya. The sector stands a chance of revival and vibrancy through the utilization of the abundant agricultural residues and feedstocks lying in the agricultural fields across the country. Similar experiences elsewhere have proved that the abundance of agricultural waste can be utilized for the production of paper and pulp due to their excellent fibre content for specialty papers, and easy pulpability. The agricultural residues are therefore considered a quintessential alternative and sustainable source of raw materials for the pulp and paper industry. Moreover, their utilization will mitigate environmental impacts such as deforestation, climate change, and pollution .

The possibility of creating wealth in pulp and paper industry from the underutilized dry matters of the leaf sheaths of the pseudostem (Musa paradisiaca and M. sapientum), leaf stalk (Carica papaya) and stems (Panicum maximum and Andropogon tectorum) have been established from the anatomical parameters and indexes (fibre lengths and diameters, lumen width, cell wall thickness, Runkels ratio, flexibility coefficient (%) and slenderness ratio) of the fibres using standard procedures. Results obtained revealed that the Runkels ratio of the fibres in the five dry matters were 0.60, 0.44, 0.40, 0.87 and 0.93 for Musa sapientum, M. paradisiaca, Carica papaya, Panicum maximum and Andropogon tectorum respectively. These values, each been less than 1 (˂ 1) recommends each of the dry matters as suitable alternative source of raw materials for pulp and paper production industry. It was recommended that these dry plant materials be henceforth harnessed as alternative sources of raw materials for pulp and paper production industry as another means of wealth creation instead of allowing them to waste and cause environmental nuisance.

Abstract Pulp and paper products in the modern world are used in a variety of types and areas, due to which the issue of improving paper production technologies is relevant. The article presents the results of grinding fibrous semi-finished products using the knife method. A disc mill with an original knife set was used as the unit under study. For the most effective modes of grinding were selected to obtain raw materials with high quality indicators.

The pulp and paper industry is advanced rapidly since there are many types of raw materials containing cellulose fibres that could be used to produce different kinds of paper by different methods in the mills. In Malaysia, one of the abundant non-wood materials for pulp and paper production is empty fruit bunch (EFB) from the oil palm. The EFB is the main fibrous residue and natural fibre which has promising potential as an alternative to replace woody materials. This study provides insight into the use of EFB as an alternative non-wood fibre resource in pulp and paper making. The potential of oil palm EFB transformed into valuable fibre material was elaborated. In this review, detailed information on the properties of EFB for pulp and paper making process to identify the chemical composition and fibre morphology were discussed. Recent advanced applications including nanocellulose from EFB, polymeric hydrogel, and antimicrobial papers were discussed to demonstrate high commercialization for pulp and paper technology. The three-dimensional (3D) printing technique has been employed due to the high complexity of paper products. The future trends and challenges regarding the use of EFB in pulp and paper making were also reviewed. This study demonstrated that the EFB has met the demand of the market chains as a potential raw material in paper making and manufacturing.

Because there is a lack of wood resources in many countries, this work focused on pulp and paper production from the waste and agricultural residues of non-wood plants. The work aimed to pulp the nitrate-alkaline of black mustard (Brassica Nigra L.) and camelina (Camelina Sativa L.). The black mustard and the camelina were selected due to the expanding planted areas of these crops in the Czech Republic. To characterize the chemical composition of black mustard and camelina, cellulose, lignin, ash, and extractives were determined. Raw alpha-cellulose, beta-cellulose, and gamma-cellulose were also measured. The results showed that the content of lignin in non-wood plants is lower than that in softwoods. The cooked pulp was characterized by the delignification degree–Kappa number. Additionally, handsheet papers were made for selected samples of pulp. The handsheet papers were characterized by tensile index, breaking length, and smoothness and compared with commonly available papers.

<em>Pulp and paper are manufactured from raw materials containing cellulose fibers, generally wood, recycled paper, and agricultural residues. In developing countries, about 60% of cellulose fibers originate from nonwood raw materials such as bagasse (sugar cane fibers), cereal straw, bamboo, reeds, esparto grass, jute, flax, and sisal. Large amount of toxic effluent is released during process of paper production. Pulp and paper mill spent wash (raw effluent) is highly acidic in nature with high BOD, COD, TDS,  TSS, phenol, sulphate, nitrogen, phosphorus, potassium and metals viz. Mn Zn Cu Ni Fe and Na . Effluent was treated with chemicals FeCl3 and KMnO4. pH was found to increase from 7.8 to 8.4 on increasing concentration (1 gl-1 to 5 gl-1) of KMnO4. Similarly colour, COD and BOD were decreasing with increasing concentration of KMnO4. Maximum colour, COD and BOD reduction were recorded 21.25%, 93.79% and 81.48% respectively at 5g l-1 concentration of KMnO4. Decrease in pH was recorded from 3.3 to 2.0 on increasing concentration (1 gl-1 to 5 gl-1) of FeCl3 (Ferric chloride).  Decrease in colour, COD and BOD were also observed with increasing concentration of FeCl3. Maximum colour, COD and BOD reduction were recorded 99.10%, 54.16% and 85.92% respectively at 5g l-1 conc. of FeCl3.</em>

Chinese Market

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.
