Impact of Retention Agents on Functional Properties of Recycled Paper in Sustainable Manufacturing

The proper dosing and optimization of retention additives are necessary to ensure the desired benefits without compromising other aspects of the paper manufacturing process. In this study, the effects of a cationic polyelectrolyte based on acrylamide and a cationic derivative of acrylic acid on the different properties of paper containing recycled fibers were investigated. The structural and tensile properties were examined through various analyses to determine the optimal dosage of the retention additive. The results obtained indicate that while the retention agent can enhance papermaking efficiency by improving retention, drainage, and sheet formation, it also negatively impacts the tensile strength and surface smoothness of the recycled paper. This complexity highlights the importance of a balanced approach in optimizing retention aid dosages. Determining the optimum dosage of such an agent requires multiple trials and analyses with varying dosages. This review aims to offer a background for engineers seeking to enhance the competitiveness and reduce production costs of their paper products, as well as for researchers striving to surpass the existing standards and achieve innovative outcomes.

The use of green synthesized TiO2/MnO2 nanoparticles in solar power membranes for pulp and paper industry wastewater treatment

The pulp and paper manufacturing wastewater is as complicated as any other industrial effluent. A promising approach to treating water is to combine photocatalysis and membrane processes. This paper demonstrates a novel photocatalytic membrane technique for solar-powered water filtration. The method is based on creating green-prepared TiO2, and MnO2 nanoparticles (NPs) using Pomegranate peels and Seder leaf extracts and incorporation into polyvinylidene chloride to produce a novel water purification system that combines semiconductor photocatalysis with membrane filtration. The prepared heterostructure of the TiO2/MnO2 nanocomposite membrane provides photogenerated charge separation. To ensure chemical bonding at the membrane surface, Raman and Fourier transform infrared spectroscopy (FT-IR) were employed. The modified membrane’s hydrophilicity and roughness increased significantly. Additionally, the modified nanocomposite membrane’s porosity was measured. The integrated process demonstrated much higher removal of humic acid and high efficiency of wastewater treatment for pulp and paper. In sunlight, humic acid removal was 98% from synthetic wastewater. While using the produced membrane on pulp and paper effluent, these studies indicate that: in the dark, the removal was 50%, while in the sunlight, the removal increased to 70%, with a reduction in the COD from 1500 mg/L to 247 mg/L. Additionally, the TDS decreased from 1630 to 452 ppt in the sunlight. This research sheds light on how solar energy can clean wastewater from the pulp and paper industry while improving membrane separation. Also, an alternative source to sunlight was used to manufacture a photocatalytic membrane with high efficiency for wastewater treatment and an inexpensive price.

Experimental investigation of pulp dewatering by high vacuum suction boxes

AbstractReducing energy consumption by industrial processes has become imperative because of rising energy costs and efforts toward decarbonisation. The continuous manufacturing of paper is energy intensive due in part to the water removal process required to convert pulp slurries to valuable paper products. This necessitates the development of energy conservation techniques, while simultaneously ensuring the quality of the product. A pilot-scale test unit was developed to quantify the effects of dwell time, vacuum pressure, and refining energy on the achievable pulp concentration or dryness level of three pulp types utilised in paper machines. Pulp dry matter was investigated as a means of gauging vacuum consumption and hence energy utilisation in paper machines, which could potentially reduce utility consumption of the overall drying process. A novel approach to simulate the pulsating high vacuum zone in the forming section of a paper machine was implemented, allowing the development of statistical correlations to explore vacuum dewatering conditions that may lead to energy efficiency. Bleached hardwood, mechanical/groundwood and recycled pulp were characterised to determine the effects of refining energy on fibre morphology and their drainage behaviour in pulp slurries. A dryness level of 21.8% at − 55 kPa gauge was achieved for bleached hardwood, whereas lower values of 19.8 and 18.3% were observed for recycled and mechanical pulps, respectively. This behaviour was attributed to the differences in drainability and morphology of the pulps due to their respective unique properties, further exaggerated by refining.

Northern European Countries in Modern Global Value Chains: Comparative Analysis

This article dwells upon the comparative aspects of Northern European countries’ participation in modern global value chains (GVCs). The aim of the research was to identify economic sectors in which the analysed countries maintain the most beneficial position in GVCs. Methodology applied is based on the calculation of the vertical specialisation indices and indicators of centrality and clustering in international production networks. New indices of relative GVC specialisation, namely GVC participation intensity index and deviation index, were introduced and applied by the author. Quantitative assessment of the network metrices is based on a construction of the international production network graph. The nodes represented 76 world largest economies and the edges were non-negative normalised quantities of intermediate products interflows. The main source of raw data is the OECD Data Explorer statistical database. Geographical scope of research covers Denmark, Norway, Finland, and Sweden. The time period is 2010‒2019, before the COVID-19 pandemics. The results obtained suggest that Northern European countries participate in GVCs differently. Denmark and Sweden are well-positioned at higher stages of the value chain, whereas Norway and Finland occupy lower stages. At the same time, Denmark and Norway display a distinctive specialisation in water transport, Finland specialises in wood and paper manufacturing, and Sweden has a competitive edge in transport manufacturing. Denmark and Sweden are firmer integrated into the international production network, and they cooperate with relatively more influential partners than that of Norway and Finland. It has been unveiled that GVC participation of the two latter countries depends greatly on the state of the global market.

Unlocking potential: the role of chemometric modeling in pulp and paper manufacturing

Unlocking potential: the role of chemometric modeling in pulp and paper manufacturing

The Valorisation of Biochar Produced from Black Liquor Pyrolysis for the Development of CO2 Adsorbents.

The paper manufacturing process produces liquid and gaseous alternative fuels, as well as solid wastes. These can be subsequently treated through chemical processing, oxidation, and thermal activation, resulting in adsorbent materials with CO2 adsorption capacities. The valorisation of black liquor waste resulting from paper manufacturing was achieved through a catalytic pyrolysis process using two catalysts previously prepared in house (Cu-Zn-MCM-41 and Ni-SBA-16). The HCl-treated adsorbent material, resulting from Ni-SBA-16-catalysed pyrolysis, was selected for use in CO2 adsorption tests as it had the highest specific surface area (224.06 m2/g) and pore volume (0.28 cm3/g). The adsorption experimental setup was linked to a gas chromatograph in order to evaluate CO2 adsorption efficiency using a binary gas mixture consisting of 81% CO2 and 19% N2. With a CO2 adsorption capacity of 1.61 mmol/g, a separation efficiency of 99.78%, and a CO2 recovery yield of 90.02%, it can be concluded that the developed adsorbent material resulting from Ni-SBA16-catalysed pyrolysis and HCl treatment represents a viable solution for black liquor pyrolytic solid waste removal and reduction in greenhouse gases.

Thiol-Based Redox Molecules: Potential Antidotes for Acrylamide Toxicity.

Acrylamide (ACR) is a low-molecular weight, non-aromatic reagent, widely used in industry, such as in the manufacture of paper, textiles, plastics, cosmetics, and dyes. ACR is formed during the cooking of starchy food and its toxicity results mainly by conferring oxidative stress by elevating reactive oxygen species (ROS). To identify potential antidotes for ACR toxicity, we evaluated the efficacy of several thiol-based molecules known for ROS-scavenging, disulfide-reducing properties, and inhibition of oxidative stress-induced activation of the mitogen-activated protein kinases (MAPKs): the extracellular-signal-regulated-kinases (ERK1/2), p38-mitogen-activated-protein-kinases (p38MAPK), and c-Jun-N-terminal-kinases (JNKs). We established a reproducible assay testing N-acetylcysteine (NAC), AD4/NACA, and the N-and C-blocked tri- and tetra-thioredoxin-mimetic (TXM) peptides, in PC12 cells. Our results demonstrate that these compounds exhibited high efficacy in suppressing ACR-induced MAPK activation, either prior to or subsequent to ACR exposure. The inhibition by single cysteine (Cys) residue, NAC and AD4/NACA (NAC-amide), 2 Cys peptides TXM-CB30, AcDCys-Gly-DCysNH2, TXM-CB20, AcCys-Gly-CysNH2, SuperDopa (SD, Ac-CysL-Levodopa-CysNH2, TXM-CB13, AcCys-Met-Lys-CysNH2, and a 3-Cys peptide, TXM-CB16, AcCys-γGlu-Cys-CysNH2 was dose-dependent and potency displayed a direct correlation with the number of Cys residues. Cellular proteolysis of SD, which consists of levodopa flanked by two Cys, may suppress the manifestation of Parkinson's disease (PD)-like symptoms mediated by chronic ACR exposure not only through lowering oxidative stress but also by replenishing cellular levels of dopamine. Overall, these results could advance the clinical application of TXM peptides as potential treatments for acute and/or chronic exposure to ACR and show promise as antidotes for preventing ACR-triggered PD-like neurotoxic symptoms.

Exploring statistical and machine learning methods for modeling probability distribution parameters in downtime length analysis: a paper manufacturing machine case study

Manufacturing companies focus on improving productivity, reducing costs, and aligning performance metrics with strategic objectives. In industries like paper manufacturing, minimizing equipment downtime is essential for maintaining high throughput. Leveraging the extensive data generated by these facilities offers opportunities for gaining competitive advantages through data-driven insights, revealing trends, patterns, and predicting future performance indicators like unplanned downtime length, which is essential in optimizing maintenance and minimizing potential losses. This paper explores statistical and machine learning techniques for modeling downtime length probability distributions and correlation with machine vibration measurements. We proposed a novel framework, employing advanced data-driven techniques like artificial neural networks (ANNs) to estimate parameters of probability distributions governing downtime lengths. Our approach specifically focuses on modeling parameters of these distribution, rather than directly modeling probability density function (PDF) values, as is common in other approaches. Experimental results indicate a significant performance boost, with the proposed method achieving up to 30% superior performance in modeling the distribution of downtime lengths compared to alternative methods. Moreover, this method facilitates unsupervised training, making it suitable for big data repositories of unlabelled data. The framework allows for potential expansion by incorporating additional input variables. In this study, machine vibration velocity measurements are selected for further investigation. The study underscores the potential of advanced data-driven techniques to enables companies to make better-informed decisions regarding their current maintenance practices and to direct improvement programs in industrial settings.

Paper fingerprint by forming fabric: analysis of periodic marks with 2D lab formation sensor and machine learning for forensic paper-identification

Abstract Weave and drainage marks on paper surfaces derived from forming fabrics installed in paper machines were examined. Non-destructive differentiation of copy papers from various manufacturers was performed by a 2D Lab Formation Sensor. Individual characteristics such as angles and wavelengths formed by the fabric were selected as parameters for the analysis. These parameters were sampled from a total of 500 papers: 50 sheets of paper from each of the 10 groups by copy paper manufacturers. Using machine learning algorithms such as partial least squares discriminant analysis (PLS-DA), k-nearest neighbors (k-NN), and naive bayes (NB) models to analyze these parameters allows for the identification of copy paper groups by manufacturers. The NB classifier demonstrated superior performance, achieving an accuracy of 0.973 even with a 50 % reduction in input variables. This study shows that periodic marks on paper surfaces can act as important indicators of the forming fabric and the distinct features of a paper-making machine. In general, this paper proposes that the 2D Lab Formation Sensor along with machine learning models can be utilized for non-destructive copy paper categorization. This identification method could be broadened to determine information regarding suspicious documents for forensic identification purposes.

Habitat assessment, population characteristics, and conservation recommendations for Nepali paper plant, Daphne bholua: ensuring the future of handmade paper production in Nepal’s Central Himalayas

Abstract Daphne bholua Buch. -Ham. ex D. Don (Thymelaeaceae) is a woody shrub native to the temperate forests of the Himalaya. Since the 12th century, the bark of D. bholua has been used as a raw material for handmade paper in Nepal, and employed for value-added products, including government documents, and religious texts. However, unsustainable commercial harvesting now threatens this centuries-old artisanal tradition. To inform and improve the conservation of this important species, we evaluated its habitat characteristics, size class distribution, and regeneration status along an elevation gradient (1900–2500 m) in Madane Mountain, central Nepal. We established 108 plots (5 m× 5 m) at three sites, each with three canopy types: closed, semi-closed, and open. We analyzed habitat characteristics, considering variations in physical and topographic variables and patterns of associated species in different elevation sites. D. bholua exhibited the highest mean density at higher elevations with minimal disturbance, whereas the lowest elevation site, experienced greater human disturbance, with the lowest density. Furthermore, the population structure displayed a ‘reverse J-shaped’ curve, suggesting favorable conditions for natural recruitment and regeneration. Our research findings also indicate that D. bholua populations thrive in semi-closed forest canopies, particularly when associated with Rhododendron arboreum, Quercus semecarpifolia, and Sarcococca coriacea. The outcomes may hold significant value for policymakers, conservationists, harvesters, paper manufacturers, and regulatory bodies aiding in development of environmentally sound conservation programs tailored to various elevations. Our key recommendation may appear surprising: we advise establishing a small, meticulously managed hand papermaking industry in the villages linked to Madane and nearby areas. This initiative would generate supplemental income and produce a culturally valuable and economically marketable product.

Brownian motion in a magneto Thermo-diffusion fluid flow over a semi-circular stretching surface

The current study explores the mass and heat transport analysis of a Casson liquid stream past a curved surface. The current model considers the effect of magnetic strength brought on by the strength of the applied uniform magnetic field. The significance of thermophoresis and Brownian motion are also taken into account using the Buongiorno nano-liquid model. The study of liquid flow over stretching sheets frequently addresses practical issues that have garnered significant attention from researchers due to their importance in various domains, including microfluidics, fibreglass production, manufacturing, transportation, metal extrusion, thermal insulation, glass production, paper manufacturing, and acoustic blasting. The governing partial differential equations (PDEs) are converted into ordinary differential equations (ODEs) using the similarity variables. These equations are numerically solved using the finite difference method (FDM). The concentration, temperature, and velocity graphs were produced by varying the different physical parameters. The upsurge in the magnetic parameter reduces the velocity profile. As the magnetic parameter increases, thermal and concentration profiles upsurge. The decrease in velocity profile can be seen as the Casson parameter rises. The intensification in values of thermophoretic parameter enhances the thermal and concentration profiles. The concentration and thermal profiles reduce as the curvature parameter upsurges.

Strategic data augmentation with CTGAN for smart manufacturing: Enhancing ML predictions of paper breaks in pulp-and-paper production

This article addresses the significant challenge posed by the rare occurrence of paper breaks in the pulp-and-paper industry, which, despite their infrequency during production, have considerable economic consequences. We analyze operational data from a paper manufacturing machine, focusing on the rare instances of paper breaks (124 out of 18,398 cases) identified through a quality assurance protocol. This scarcity presents a challenge for machine learning-based predictive models. To overcome this, we introduce a novel data augmentation strategy using Conditional Generative Adversarial Networks (CTGAN) and Synthetic Minority Oversampling Technique (SMOTE), aimed at generating synthetic data that not only reflects the real operational data’s distribution but also improves the predictive models’ performance metrics. We assess the impact of this data augmentation on three machine learning algorithms—Decision Trees (DT), Random Forest (RF), and Logistic Regression (LR)—both before and after augmentation. The use of a CTGAN-enhanced dataset led to notable enhancements in predictive maintenance metrics. Specifically, the ability of the models to detect machine breaks (Class 1) increased significantly: over 30% for Decision Trees, 20% for Random Forest, and nearly 90% for Logistic Regression. This methodological progress offers valuable contributions to the fields of industrial quality control and maintenance scheduling by improving the prediction of rare events in manufacturing processes.

Analysis of technologies of disposal and use fibrous paper skopje

The article examines the current state and trends in the development of waste management technologies in the pulp and paper industry, with the aim of analyzing the reasons that hinder, and sometimes make impossible, the effective utilization of fibrous waste paper to obtain environmentally safe materials and raw products. The production of paper products is one of the most capital-intensive and energy-intensive industries, second only to the metallurgical and chemical industries, with a correspondingly large amount of waste and a negative impact on the environment. The technological processes of scum formation as a result of waste paper recycling and paper production wastewater treatment are considered and analyzed. Skopje is the final waste of the pulp and paper industry, which is formed at various stages of the paper and cardboard manufacturing process, therefore it is deposited in landfills. Multiton volumes of skopje require significant areas for its storage. Despite the low IV hazard class, this leads to serious environmental problems, as the leachate from the skopje landfill pollutes surface and ground water. Technologies of possible disposal and reuse of skopje, known in domestic and foreign literature, are described and analyzed. The technology of reusing scoop is determined by its relatively environmentally safe physicochemical composition. The indicated fibrous, mineral, extractive constituents and lignin determine the possibility of reusing skopje, mainly for the construction industry. The perspective of the complex use of multi-tonnage waste – slag, sludge, ash and slag of thermal power plants as plasticizers, fillers, binders and binding components in the production of building structural and heat-insulating materials is named. Technologies for using scapula as a filler in the production of building materials require a high content of inorganic compounds and a minimum amount of organic compounds. A high content of fibrous particles and a low content of mineral substances is necessary when using scapula in the production of composite wood composite materials. The specified technological limitations ensure only small amounts of skopje use in the production of building materials. The effectiveness of using skopje as an additive to the asphalt mixture for road construction and production of fuel materials is determined by the economic costs of transportation and dewatering. It is noted that the high humidity, ash content and low calorific value of scum are the main reason for the lack of effective technologies for its utilization. The solution to the problem is the use of low-energy technologies through the direct use of osprey as a component of the soil mixture for biological reclamation of man-made landscapes. The article substantiates an environmentally safe and socially favourable option for using a soil substrate based on osprey. It is emphasised that the humidity and organic viscosity of the plant origin of osprey form the agrotechnical properties of soil substrates of prolonged action, which ensure optimal technological efficiency of phytomelioration of degraded lands. The reclaimed areas will reduce greenhouse gas emissions from the soil, prevent wind and water erosion, and ensure the environmental safety of natural and man-made ecosystems.

Nanocellulose prepared with γ-valerolactone pretreatment and its enhancement in colored paper

New techniques are always demanded to pursuit green and economical ways for nanocellulose preparation. We herein proposed to use γ-valerolactone (GVL) to facilitate the nanocellulose preparation from bleached bamboo pulp fibers as a green and sustainable pretreatment. The GVL pretreatment caused the bamboo fibers to destruct, resulting in an obviously increased fine fiber content, which was systematically studied to disclose the influence of different factors on the fiber changes. The optimum GVL pretreatment conditions were determined as reaction time of 4 h, reaction temperature of 140 °C and the ratio of GVL to water of 4:1. Notably, the GVL pretreatment caused negligible changes in the functional groups on cellulose, as well as its crystalline structure. The resultant nanocellulose (i.e. G-CNF) had a width of ca. 47 nm and it showed good adsorption capacity towards RR195 dye since an impressive dye uptake rate of 46.81 % was attained. The incorporation of G-CNF significantly improved the coloring performance and the ∆E (color difference) value reached up to 33.73. Improvements in the mechanical properties of RR195 dyed paper were also observed with the incorporation of G-CNF. This work sheds light on the nanocellulose preparation with GVL pretreatment and demonstrates a feasible way to apply the resultant nanocellulose in the colored paper manufacture.

Application of microscopic imaging, multispectral techniques, and SEM/EDS analysis to the study of 19th century colour engravings

This study was carried out on a collection of coloured gravures, which are bound in one book volume entitled “Histoire Naturelle des Perroquets”. This book belongs to the Benaki's Collection of the Hellenic Parliament Library, Athens, Greece. Each page has a coloured print, depicting a different bird species. In most cases, the prints present oxidations caused by the additives used in paper and printing inks manufacture, i.e. fillers, sizing agents, binders, solvents, and other chemical compounds.By employing microscopic imaging, multispectral imaging, and Scanning Electron Microscopy/Energy Dispersive X-ray spectroscopy (SEM/EDS) analysis significant information on the materials used, engraving techniques, as well as the preservation state of the printings studied can be obtained. The combination of the proposed methods yields successful results in identifying the materials used in the colour inks, as well as the paper support of the printings.

The current research recommends experimenting with the aesthetics of collage art using other materials.

Enhanced biodegradation of lignin and lignocellulose constituents in the pulp and paper industry black liquor using integrated magnetite nanoparticles/bacterial assemblage

The study was designed to explore the efficiency of magnetite nanoparticles (Fe3O4 NPs)/bacterial cell assembly to biodegrade lignin and lignocellulose, decontaminate pulp and paper-contaminated wastewater and optimize lignin adsorption by Fe3O4 NPs. Water samples were collected from three paper and carton manufacturing companies, Alexandria Governorate, Egypt. Pseudomonas otitidis MCC10330, the most active and promising strain among 10 previously screened indigenous and exogenous isolates, was selected and decorated with magnetic Fe3O4 Nanoparticles, that were prepared by the co-precipitation method, characterized and used to decontaminate paper and pulp effluent in a batch mode bioassay for 4 h. Fe3O4 NPs/bacterial cell assembly achieved the highest removals (64.1, 52.0, 54.3 and 66.6%) of TSS, COD, BOD, and Total Tannin and Lignin after 1, 4 and 4 h, reaching residual concentrations (RCs) of 322, 216, 112 and 7 mg/L, which are still slightly higher (5.35, 2.7 and 1.86-fold) than their maximum permissible limits (MPLs), respectively. RCs of pH, DO and TDS in the treated effluent are accepted for safe discharging. Maximum lignin adsorption and removal (82.14%) using Fe3O4 NPs was achieved at the optimized conditions (pH 6, Fe3O4 NPs dosage of 100 mg and 10 min contact time). Results confirmed that the proposed magnetite-coated Pseudomonas otitidis treatment system is highly efficient and recommended to treat the highly contaminated pulp and paper wastewater. Also, as far as we know, this integrated assemblage is the first time to be used as a novel, very promising, eco-friendly, renewable and economical biotechnological approach to minimize/eliminate the involved pollutants with the least running time.

Studies of Wastewater Management through Microbiology of Constructed Wetland

Constructed wetlands are distinguished by certain environmental factors that let many physical and biological processes to occur simultaneously. This is the outcome of a particular habitat that supports the development of microbes and hydrophytes, which are plants that can live in aquatic and semiaquatic environments and are capable of anaerobic, anaerobic, and aerobic environments. Their combined activity amplifies the processes of oxidation and reduction, which are in charge of eliminating and holding onto contaminants. Sorption, sedimentation, and absorption all aid in these processes. Treatment wetland systems have been employed in community management for more than 50 years because of these benefits. Constructed wetlands are becoming more and more popular for treating or pre-treating many kinds of industrial wastewater because of their benefits, cheap operating costs, and high removal efficiency. The paper examines how these facilities are being used worldwide to treat industrial wastewater. With a focus on particular and distinctive pollutants from industries, the conditions of usage and efficacy of pollutants removal from wastewater that degrades quickly and slowly were described. The article addressed the use of subsurface horizontal flow beds for the treatment of wastewater from various industrial processes, including the manufacturing of paper, oil, and coffee, as well as the food sector, which includes wineries and distilleries. Constructed wetlands are used in Poland to treat wastewater and milk processing sludge on a pilot size or to dewater sewage sludge generated in municipal wastewater treatment plants that handle household sewage with around 40% of wastewater from the dairy and fish industries. Constructed wetlands provide the so-called ecosystem function in addition to an adequate degree of treatment in every instance.

Enhancing Performance: The Role of Organizational Culture, Commitment, and Support in Indonesian Paper Industry

Human resources play an important role in the successful achievement of performance. Employee performance is the result of the work achieved by employees in a company. This study aims to investigate the impact of organizational culture, organizational commitment, and perceived organizational support on employee performance at a paper manufacturing plant. The descriptive data and SEM were analyzed using The Jeffreys’s Amazing Statistics Program (JASP) method. Data were collected from 107 respondents who participated in paper manufacturing plants (52 males (48.6%), 55 females (51.4%); MageMage= 38, SD = 8.4). The results showed that (1) organizational culture has a significant effect on employee performance (β = 0,533, p 0,05). (3) Perceived organizational support has no significant effect on employee performance (β = 0,039, p > 0.05). In this study, organizational commitment and perceived organizational support did not influence employee performance. Among employees, expectations for increasing organizational commitment and perceptions of organizational support for improving employee performance are still not high enough. The findings of this study highlight that organizational culture has the strongest influence compared to organizational commitment and perceived organizational support on employee performance. To improve employee performance, organizations can internalize cultural values through socialization activities, corporate culture training, and cultural rituals so that employee work behavior will develop, contributing to improved performance in the organization.
