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.

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 .

In order to reduce the demand for the forest based raw materials by the organised industrial sectors like the large integrated pulp and paper mills, the Government of India started promoting several small-scale pulp and paper mills based on non-wood agricultural residue raw materials. However promotion of these small mills has created another environmental problem i.e. severe water pollution due to non-recovery of chemicals. Because of the typical characteristics like high silica content etc. of the black liquor produced and the subsequent high capital investment needed for a recovery system, it is not economically feasible for the small Indian mills to recover the chemicals. While the quantity of wastewater generated per tonne of paper produced by a small mill is same as from a large integrated pulp and paper mill with a chemical recovery system, their BOD load is four times higher, due to non recovery of chemicals. However the existing wastewater disposal standards are uniform for large and small mills for e.g. 30 mg BOD/l. To meet these standards, the small mills have to install a capital intensive wastewater treatment plant with heavy recurring operating costs. Therefore the feasible alternative is to implement various pollution abatement measures, with the objective of not only reducing the fibre/chemical loss but also to reduce the investment and operating costs of the final wastewater treatment system. To illustrate this approach, a case study on water pollution abatement and control in a 10 TPD mill, will be discussed.
