“…As a new type of energy crop with high efficiency and economy, it has attracted attention. It is often used in animal husbandry feed (Peng et al, 2010) and pulp or paper manufacturing (Jiang et al, 2019). In recent years, it has also been used in soil and water conservation, ecological environment degradation control, and other environmental control aspects (Zhao et al, 2015).…”

This research focuses on the preparation of cellulose nanocrystals (CNCs) from Pennisetum hydridum fertilized by municipal sewage sludge (MSS) through sulfuric acid hydrolysis in different acid concentrations (40–65%), temperature (room temperature ∼55°C), and reaction time (50–120 min). The results showed that the obtained CNC possessed stable dispersion in water. The length of CNCs reached 272.5 nm under the condition of room temperature (RT), 65% acid concentration, and 120 min reaction time, and the diameter was within 10 nm. Furthermore, Fourier transform infrared (FTIR) showed that the CNC still kept the cellulose type I structure. The crystallinity of CNCs increased to the maximum by 18.34% compared with that of delignified Pennisetum hydridum fibers. Thermogravimetry (TG) illustrated the thermal stability of CNCs was lower than that of delignified Pennisetum hydridum fibers due to the introduction of sulfate groups in the cellulose. This study demonstrated that Pennisetum hydridum fertilized by MSS might be a suitable raw material for CNCs. This implies meaningful resource utilization of MSS and Pennisetum hydridum.

“…The bonding of fibre became increasingly tight, and the fibrillation became more visible with the additional beating process ( Figure 4 e). As stated by Jiang et al [ 78 ], over half of the increase in fibre strength is due to beating, which straightens the fibre during the pulping process, removing curls and kinks. Additionally, fibrillation can also be attributed to the removal of lignin and other structural effects [ 79 ].…”

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.

“…The treated wastewater produced through membrane filtration complied with local legislation standards, and the wastewater contents are less than 50 mg [53,54]. The advantages of physical treatment methods are high treatment efficiency and good treatment effect; however, there are also certain disadvantages, such as the generation of a large amount of waste liquid during the treatment process and high treatment costs [55].…”

The pulp and paper industry plays an important role in the global economy and is inextricably linked to human life. Due to its large scale, the production process generates a large amount of wastewater, which poses a major threat to the environment. The sustainable utilization and safe treatment of pulp and paper wastewater can effectively reduce environmental pollution, improve resource utilization efficiency, protect water resources, provide economic benefits for pulp and paper enterprises, and thus promote the green and sustainable development of the pulp and paper industry. Therefore, this study discusses the pollution components of pulp and paper wastewater and their impact on the environment and human health. In this review, we aim to explore the sustainable development of pulp and paper wastewater by summarizing the characteristics of current pulp and paper wastewater, the commonly used treatment methods for pulp and paper wastewater, the application of pulp and paper wastewater recycling, and the future development direction of pulp and paper wastewater.
