Abstract:
An integrated and feasible approach was proposed using the underutilized grass fibre (stem) derived from Napier grass and sugarcane for paper production in this study. To enhance paper strength, pre-hydrolysis and beating techniques have been used to improve the chemical pulps and mechanical pulping process, respectively. Napier grass and sugarcane are promising non-wood sources for pulp production, owing to their high cellulose and low lignin and extractive content. With the additional mild alkaline pre-treatment to the mechanical pulping process, the lignin content was greatly reduced. The results reveal that the mechanical pulping with alkaline pre-treatment may indeed potentially replace the most prevalent pulping process (chemical pulping). As evidenced by the paper strength properties, mechanical pulping is far more suitable for grass-type biomass, particularly Napier grass, which had a folding endurance capability five times greater than chemical pulping. Furthermore, the remaining high hemicellulose content from mechanical pulping contributed to a high pulp yield, while also facilitating the fibrillation on the sugarcane’s laboratory paper handsheet. The findings also demonstrated that the additional beating process from chemical pulping causes the fibres to be drawn toward each other, resulting in a more robust fibre network that contributes to good paper strength. Consequently, this work sheds new light on the development of advanced paper derived from grass fibre.

Abstract:
Abstract Mechanical pulp for printing paper can be produced with a process that involve much less equipment and that require much lower specific energy compared to conventional processes. Even though common evaluation methods, e.g. handsheet testing, have shown that the pulp quality is similar for the simplified and the conventional processes, it is not known how fibre properties, at the microscopic level, is developed with the simplified process. In this mill scale study, the fibre properties attained with an “intensified” mechanical pulping process, consisting of single stage high consistency double disc refining followed by two stage low consistency refining and no reject treatment was investigated. The simplified process was compared to a process with a reject system. The simplified process rendered fibres with higher degree of fibrillation, higher share of axial splits, lower fibre wall thickness but slightly lower length than the conventional process. The fibrillar fines size distribution of the two processes was different. The conventional process generated more of small fibrillar fines which probably explains the higher tensile index at given density for that process. The results show that it is possible to simplify the production process for mechanical pulp and reduce the specific energy with over 700 kWh/adt.

Abstract:
AbstractThis paper is a review of the development of the mechanical pulping process with focus on refiner-based processes. The intention is to provide an overview of the trends and the major advances in the development of the mechanical pulping (MP) process. The focus is on the development of the entire MP process, rather than the refiner as such. However, when discussing the MP process development, it is inevitable to consider the development of the refiner unit operation briefly. Processes for printing papers based on softwood is mainly discussed, but board processes are discussed briefly as well.

Abstract:
Traditional chemical-machinery producing mainly took the refiner as the primary refining equipment. Extrusion pulping was the reformation of traditional refining pulping. The different equipments and processes resulted in the different characteristics of wastewater inevitably. This article aimed to compare the characteristics and biochemical treatment methods between conventional chemical-mechanical pulping and extrusion pulping, and then discuss the biochemical treatment advantages of extrusion pulping wastewater. The result shows that: the wastewater from the extrusion pulping has lower concentration of tiny fiber, load suspended matter, wastewater temperature and effluent discharge. And thus make a simpler process, a lower cost and a better effect of the wastewater treatment.

Abstract:
One way to minimize emissions of greenhouse gases that contribute to climate change is to reduce the use of wood as the main material for pulp and paper production. Therefore, non-woody plants such as bamboo can be alternatives as raw materials for pulp and paper. This study aims to determine the effect of the different bamboo species and age on the bamboo pulping yield and bamboo mechanical paper properties. Bambusa vulgaris, Gigantochloa levis, and Gigantochloa scortechinii bamboo species or locally known as Aur, Beting, and Semantan bamboo at the age of 1, 3, and 5-year old, were pulped using Soda-Anthraquinone (AQ) pulping. No beating process was conducted to all the papermaking processes to evaluate the basic mechanical properties of the bamboo paper. Pulping yield ranged from 35.7 to 51.7% at different bamboo species and age, with the pulping conditions at 20% of NaOH, 170ºC pulping temperature, 90 min time to reach pulping temperature and 90 min time at pulping temperature, 1:6 of bamboo to liquor ratio and 0.1% of AQ based on bamboo oven-dried weight. The paper was made according to TAPPI Standard T205 sp- 95. The paper mechanical properties for burst index, tear index, tensile index, and folding endurance ranged from 1.32 to 2.36 kPa.m2/g, 7.48 to 14.9 Nm2/g, 16.02 to 29.68 Nm/g, and 2 to 28 double folds, respectively, at different bamboo species and age. It was found that Beting bamboo has the potential to be a viable raw material for pulp and paper products as it shows the highest mechanical properties compared to Aur and Semantan.
