Composites are pivotal in Europe's evolving packaging sector, which is undergoing changes due to circular and bioeconomy initiatives, which prioritize eco‐friendly packaging. Despite paper's high recycling rates, dynamic markets challenge recycling and circularity. Innovative paper‐based composites demand flexible recyclability assessments, which impacts product development. Recyclability methods are evolving as they struggle to match the dynamic changes occurring in the packaging sector. This article outlines paper recycling and compares global lab recyclability evaluation methods. [ABSTRACT FROM AUTHOR]

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.

Since the implementation of the Excellence Initiative and the Excellence Strategy, German higher education institutions have been restructuring university governance, especially those selected as Universities of Excellence. This study uses a holistic and mission-related integrated governance approach to conduct a qualitative analysis of the governance transformation of German Universities of Excellence, aiming to provoke discussion on transforming governance to optimize organizational effectiveness and sustainable development of German higher education institutions. Transforming governance of German Universities of Excellence involves mission statements, strategic goals, institutional strategies, research, teaching, the third mission, internationalization, global engagement, governance relationships and structures, institutional leadership, funding, autonomy, innovation, digital transformation, quality assurance, and sustainable development, aiming to enhance accountability, performativity, transparency, openness and organizational effectiveness with efficient administrative management in alignment with institutional missions, vision, core values, and strategic goals.

Education is considered an integral element of sustainable development, and Sustainable Development Goal (SDG) 4 on quality education is a key enabler for all other SDGs. Therefore, research is primarily focused on the roles and responsibilities of higher education systems, and in the same direction, a novel system, method, and perspective plan in the form of a project is proposed that will facilitate the formation of a global knowledge hub, a data service provider for common people, for researchers, for the Ministry, for each institution, for UN representatives, and for other associated stakeholders. In addition to this, this will exactly reflect the contributions made so far by higher education systems and their' outcomes. This will also reflect how higher education systems are helping to achieve the 17 UN Sustainable Development Goals and their targets by 2030. In the paper, some additional useful information is cited pertaining to UN-SDGs based on the published documents in a sequential and systematic manner, and this will help to understand better the mission, vision, and objectives of UN Sustainable Development Goals, what are the roles and responsibilities of higher education systems in the same context till 2030 onwards with a constant approach, the initiatives that have been taken so far, and the initiatives being undertaken now. Some additional measures and discussions about convergence are also suggested. It is also well discussed about the SDG Index and Dashboards and about some major thrust areas. Since some additional useful information is cited, the source of information for each citation is properly mentioned in the references column.

In recent years, paper‐based functional materials have received extensive attention in the field of energy storage due to their advantages of rich and adjustable porous network structure and good flexibility. As an important energy storage device, paper‐based supercapacitors have important application prospects in many fields and have also received extensive attention from researchers in recent years. At present, researchers have modified and regulated paper‐based materials by different means such as structural design and material composition to enhance their electrochemical storage capacity. The development of paper‐based supercapacitors provides an important direction for the development of green and sustainable energy. Therefore, it is of great significance to summarize the relevant work of paper‐based supercapacitors for their rapid development and application. In this review, the recent research progress of paper‐based supercapacitors based on cellulose was summarized in terms of various cellulose‐based composites, preparation skills, and electrochemical performance. Finally, some opinions on the problems in the development of this field and the future development trend were proposed. It is hoped that this review can provide valuable references and ideas for the rapid development of paper‐based energy storage devices. [ABSTRACT FROM AUTHOR]

Polymeric wet-strength agents are important additives used in the paper industry to improve the mechanical properties of paper products, especially when they come into contact with water. These agents play a crucial role in enhancing the durability, strength, and dimensional stability of paper products. The aim of this review is to provide an overview of the different types of wet-strength agents available and their mechanisms of action. We will also discuss the challenges associated with the use of wet-strength agents and the recent advances in the development of more sustainable and environmentally friendly agents. As the demand for more sustainable and durable paper products continues to grow, the use of wet-strength agents is expected to increase in the coming years. [ABSTRACT FROM AUTHOR]

This paper adds to the growing literature that critically examines the cultural politics of the OECD's framework of global competence by turning our attention to the 'affective ideology' underlying this framework, namely, how affect is used ideologically to produce specific subjectivities and moralities in students. Building upon the work of affect theories in education policy, this paper explores how the concept of global and intercultural competences, as it is manifested in the OECD global competence framework, constitutes a site of affective sense-making and affective governance. In particular, the analysis reveals two ways in which this happens: first, by capitalising on global and intercultural competencies as self-centred, emotional skills to sell policy and pedagogical ideas and tools; second, by using certain affects as moral imperatives to shape global competence in intercultural communication education. The paper concludes with a discussion of the research, policy, and pedagogy implications for intercultural communication education.

The accumulation of petroleum-based plastic waste is a growing environmental concern, thus an effective plastic waste recycling scheme is crucial. This study combined waste acrylonitrile-butadiene-styrene copolymer (ABS) plastics with waste delivery boxes to create ABS/paper biocomposites. Calcium carbonate (CaCO3) was utilised as the experimental variable, while two control groups were established to investigate varying ratios of acrylonitrile-butadiene-styrene (ABS) and paper. The results indicate that ABS/paper (CaCO3) 4:6 demonstrated a tensile strength of 47.81 MPa and a bending strength of 40.92 MPa. In contrast, ABS/paper (CaCO3) 7:3 exhibited a water absorption ratio of only 1.21% within 48 h. Scanning electron microscopy revealed that high-temperature melted ABS effectively filled the voids of interwoven cellulose during hot pressing. Furthermore, adding CaCO3 improved the flame retardancy of ABS/paper biocomposites and promoted the interweaving of celluloses. The ABS/paper biocomposites preparation method represents a viable solution to mitigate plastic pollution due to its environmentally-friendly, lightweight, and low energy consumption properties.

To overcome the human and animal survivability risk, sustainable development is the only option on earth that can be achieved through the maximum use of renewable environmental resources. Recycling of waste paper is an emerging waste management approach to conserve natural resources. Herein, we studied enzyme-mediated process to recycle the xerographic paper by using the crude fungal extract from indigenously isolated fungi identified as Aspergillus assiutensis. The fungal enzyme cocktail has been characterized for the production of multiple enzymes namely cellulase, amylase, xylanase, pectinase, and protease. All these enzymes have pH optima in the acidic range and except cellulase and all the enzymes are stable from 10 to 80 C. In the zymogram analysis, pectinase, xylanase, amylase, and cellulase were detected at 68 kDa, ~ 54 kDa, 38 kDa, and 30 kDa, respectively. Also, the presence of protease was confirmed by the clear zone at 68, 31, and 16 kDa. A 26% decrease in the kappa number and reduction in Hex A of the pulp was observed on the treatment of the pulp with enzyme as compared to the control pulp without any treatment. The physical and chemical properties of the pulp were also improved by enzyme-mediated pulping as compared to the control The physiochemical parameter of the effluent like TDS was reduced (397 ppm) significantly in comparison to chemical deinking process and it was within the permissible limit. BOD and alkalinity were reduced when the enzymes and chemical dosage were used in combination. These results indicate that chemi-enzymatic deinking is most promising to reduce or remove the pollution parameters including ink and this approach can be used in the paper and pulp industry for sustainable development.

Petroleum-based plastics are useful, but they pose a huge threat to the environment and human health. The development of sustainable cellulose paper materials with excellent mechanical and water-resistance properties to replace plastics is highly desirable but also challenging. Herein, we report a new kind of rosin-based modifier synthesized from fully hydrogenated rosin and (3-glycidoxypropyl)triethoxysilane, which can covalently bind with cellulose fiber networks to improve the hydrophobicity and weaken the capillarity of cellulose paper. The rosin-grafted cellulose composite paper shows a unique combination of water resistance (water absorption of 19.2% and 37.9% in 25 and 90 °C water, respectively) and high strength (tensile strength of 47.9 MPa and Young's modulus of 2.32 GPa). Moreover, the rosin-grafted cellulose composite paper can be completely degraded when buried in soil for up to 100 days, and it can be recycled when treated with an alkali. These impressive performances make rosin-grafted cellulose composite paper a promising eco-friendly alternative material to replace plastics in straws, boxes, cups, bags and so on.

The relationship between environmental regulation and firm productivity has been widely debated but inconsistencies in findings across different studies. Using detailed firm-level micro-data from 2000 to 2007, this paper employs difference-in-difference combined with matching based on entropy balancing method to explore the effect of environmental regulation on firm total factor productivity (TFP) in pulp and paper industry in China. Our main findings are as following: Firstly, stricter environmental regulation, as represented by the Wastewater Discharge Standards for Pulp and Paper Industry in Shandong province, increases firm TFP significantly. Moreover, the coefficients of interest are robust to multiple robustness checks. Secondly, dynamic effects estimates reveal that when faced with this phase-in environmental regulation, firms take the foreseeably increasing strictness into account from the very beginning and prefer to take one-step adjustment to reach full compliance. Thirdly, potential mechanism analysis finds that the positive effect mainly comes from the improvement of resource allocation efficiency within firms. Fourthly, the heterogeneity test indicates that the effect of environmental regulation on firm TFP is heterogeneous across firms with different sizes, ages, ownerships, capital intensity, and export status. Finally, this paper provides convincing and insightful evidence that environmental regulation has the potential to achieve the dual goals of environmental sustainability and economic growth and is thus of broader significance for understanding the enforcement of environmental regulation in developing countries.

Climate change as a matter had little attention of public debate, especially in developing countries, until the recent floods caused by the dragon storms in the Middle East and the forest fires in the Mediterranean. Egypt, being strategically crucial in Africa, the Mediterranean, and the Arab world, with strong connections to other countries, aimed to go from promises to action and to discover real answers to climate change by building on past COPs. The administration assumed a more prominent role by coordinating the 27th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP27). People started to realize that this is not something only happening elsewhere in the world. Egypt took the initiative; Challenges have been assessed to reach suitable mitigation approaches, and Egypt's first NDC has been issued to meet the global agenda. Egypt's vision was to accelerate global climate action at the UNFCCC 27th Conference of the Parties (COP 27) through emissions reduction, advanced adaptation, and enhanced flow of appropriate finance, prioritizing developing countries worldwide.

This study investigates the influence of fiber modification methods and beating degrees on the properties of paper sheets. Two different methods were used to modify fibers: NaOH + urea and TEMPO ((2,2,6,6-tetramethylpiperidin-1-yl)oxidanyl) and blended with traditional paper fibers. Subsequently, we evaluated the resulting sheets for their optical, strength, and thermo-mechanical characteristics. Notably, we also scrutinized sheets created exclusively with 100% TEMPO-modified fibers. The addition of modified fibers led to improvements in several strength properties, but it had a noteworthy negative impact on the optical properties of TEMPO-treated fibers compared to the other papers. Furthermore, thermal analysis revealed that the contraction rates of the samples increased considerably up to 40–50 °C for the out-of-plane direction and surpassed 130 °C for the in-plane direction. In general, the inclusion of modified fibers had a significant effect on thermo-mechanical properties. Specifically, TEMPO modification resulted in an increase in the maximum in-plane contraction ratio, shifting it from −0.40% to −0.59%, along with its corresponding temperature. This research underscores the potential of modified fibers to enhance paper properties and contribute to the development of more sustainable paper-based products. [ABSTRACT FROM AUTHOR]

Livestock dung, discarded crop straws, and residual plastic film are the primary agricultural non-point sources of pollution. For livestock dung and discarded crop straw, the general treatment focuses on compost, animal fodder, industrial raw material, and new energy. The development of degradable mulch film is the main way to solve pollution from residual plastic film. However, an effective way to solve the above three types of pollution simultaneously and use them for ecological circular agriculture has been less studied. In this study, using cow dung and flax straw wastes as raw materials, we prepared natural, fibre-based paper mulch using the rapid-Kothen method and analysed the film-forming mechanism. Based on the Van Soest method, the cow dung and flax straw waste contain abundant cellulose fibres: 36.75% and 54.69%, respectively. The tensile strength and tear strength of fibre paper mulch are 1.87 kN/m and 19.91 N/mm, respectively. To enhance the adaptability of the fibre paper mulch in humid environments, the surface of the mulch was treated with alkyl ketene dimer (AKD). The AKD-coated fibre paper mulch displays hydrophobic properties, indicated by a contact angle of 128° ± 2°. It has a wet tensile strength of 0.64 kN/m and a wet tear strength of 8.23 N/mm. Additionally, it exhibits a dry tensile strength and a tear strength of 2.13 kN/m and 16.43 N/mm, respectively. Notably, the dry tensile strength is increased by 16.31%. In this way, the livestock dung and discarded crop straw can be reused, reducing dung pollution and straw burning in livestock farms, and the final products can alleviate the residual film pollution simultaneously.

Universities can play a key role in contributing to a sustainable future for our planet and its inhabitants. In times of constant changes, there is a growing urgency to reflect on the vision of universities as well as their respective practices and projects that can promote the creation of sustainable societies. As is evident in scholarly literature, there is a need to empower universities and enhance their ability to prepare individuals who can confront global sustainability challenges and pursue sustainable development. The United Nations' adoption of the 2030 Agenda for Sustainable Development in 2015 recognised that societal problems were territorially blind, meaning that no country has sufficient knowledge or research capacity to solve all challenges on its own. To that end, this qualitative, comparative research study represents the unified effort of two very different countries to explore the topic of education for sustainable development (SD) at universities. The study employed a document analysis of selected publicly funded universities in Canada and South Africa. Gathered documents are from the past seven years and include the universities' mission and vision statements, annual reports, and strategic plans. The three main questions addressed in this work are: (a) What is the status and role of higher education for SD in Canada and South Africa? (b) What areas of SD are on the agenda of universities under investigation in Canada and South Africa? (c) What are the main similarities and differences between the two contexts under investigation? Findings indicate that universities focus on several aspects of SD, namely sustainable education, sustainable relationships, and sustainable initiatives. The paper discusses these areas for each country in connection to their contextual setting. Although the study's findings cannot be generalised, they can be informative for other universities and contexts and thus contribute to the body of knowledge about education for SD in higher education.

Abstract In this work, fabrication of frequency selective surface filters by coating paper with silver ink and subsequent laser etching the frequency filter pattern has been investigated. Three filter structures consisting of a combination of square and ring patches operating at 102, 113, and 126 GHz and with corresponding signal attenuation of −15.2, −15.4, and −14.5 dB were fabricated and simulated; −5 dB bandwidths were following, 93.3–112.2 GHz, 101.9–121.1 GHz, and 112.7–132.3, respectively. Also, the proposed screen printing with assistive laser etching could be used to reduce the number of used screens. Furthermore, paper based fabrication using a biodegradable ink could be an alternative fabrication process in future electronic manufacturing.

China's pulp and paper industry (CPPI) has been always the main carbon emission source in recent years. However, the analysis on influencing factors of carbon emissions from this industry is insufficient. To address the issue, the CO2 emissions from CPPI are estimated in the period of 2005–2019, the driving factors of CO2 emissions are investigated by the logarithmic mean Divisia index (LMDI) method, the decoupling state of economic growth and CO2 emissions is determined by Tapio decoupling model, and finally, future CO2 emissions are predicted under four scenarios by the STIRPAT model to explore the potential of carbon peaking. The results show that CPPI exhibits a rapid increase and a fluctuating downward trend in CO2 emissions during the period of 2005–2013 and 2014–2019, respectively. The main promoting and inhibiting factors to the increase of CO2 emission are per capita industrial output value and energy intensity, respectively. There are five decoupling states of CO2 emissions and economic growth during the study period, and the CO2 emissions exhibit a weak decoupling state with the industrial output value growth in most years of the study period. It is very difficult to realize the carbon peaking goal by 2030 under the baseline and fast development scenarios. Therefore, efficient low carbon and strong low-carbon development policies are necessary and urgent for the realization of carbon peaking goal and the sustainable development of CPPI.

Sustainable agricultural production is essential for an adequate food supply to feed the global population. One facet of efforts in making the agricultural sector more sustainable is the dramatic increase in organic farming (OF). With its current popularity, people across the globe are increasingly interested in the sustainable performance of organic production. However, accurate and timely information is scarce and there is a lacuna of knowledge among organic farmers about Sustainability Assessment (SA). Many promising SA measurement tools have been developed for the organic farming sector. However, improved procedures and a broader common knowledge are still necessary. In response, this paper provides a comprehensive comparison and scientific underpinning of the prominent tools for assessing farm sustainability to provide support for monitoring sustainable development in OF practices. This comparison can contribute to the adoption of suitable SA tools, and, thereby, the achievement of the United Nations (UN) Sustainable Development goals by 2030.

Global community is increasingly alarmed by resource depletion and environmental pollution. In light of pressing environmental concerns and depletion of finite resources, the surge in fossil fuel usage has sparked twin crises: dwindling fossil fuel reserves and escalating environmental pollution. The current study introduces a novel approach to minimize waste by transforming it into briquettes suitable for large-scale production. Production of briquettes involves multiple stages, including collection, drying, crushing, screening, blending, compacting, and storage. The main objective of this research is to demonstrate and investigate the physico-mechanical and emission properties of briquettes produced with readily available organic fraction of municipal solid waste (MSW) such as food and garden waste. The physical, mechanical, and elemental characteristics such as calorific value, moisture content, ash, volatile matter, fixed carbon, density, compressive strength, and SEM-EDAX were determined. A combustibility test along with emission and water boiling test was also carried out. The MSW briquettes were prepared in a densification system at 130 °C temperature and 20 MPa. The study's conclusion suggests that the MSW briquette with lignin content of 25-30%, calorific value of 22.53 MJ/kg, compressive strength of 14.517 N/mm 2 , and density of 1124.12 kg m -3 could be used to retain energy and lessen the harmful effects of climate change while also enhancing sustainability. Flue gas emissions from burning MSW briquettes in a biomass stove were examined in this study using flue gas analyzer and smoke meter. Furthermore, the generated briquettes exhibit a density of 1124.12 kg m -3 which is on par with coal, making them suitable for co-firing in boilers. Likewise, the determined parameters are compared with the biomass briquettes and firewood. Further investigation is required to elevate its quality and economic potential., (© 2024.

This paper examines sustainable development, which employs an integrated approach to tackle environmental, social, and economic challenges. It provides a theoretical underpinning by examining sustainable development's inception, fundamental tenets, and conceptual structures. This study highlights the interdependence of social equity, economic prosperity, and environmental conservation, emphasizing the need for a comprehensive approach. Quantitative methodology is utilized in this study, and the dependent variable is sustainable development. Financial risk, green growth, technological innovation, renewable energy, financial inclusion, and soft infrastructure are all independent variables. The analysis is predicated on secondary data from the Organization for Economic Cooperation and Development and World Development Indicators databases spanning 2004 to 2019. An entropy-weighted method used for the green growth index is a metric that enhances the precision of variable indicators. Cointegration, correlation, VIF, cross-sectional dependency, and stationarity tests are among the diagnostic tests that inform the selection of methods for the panel data set. It is determined that fully modified ordinary least squares is the suitable technique. The findings suggest statistically significant positive correlations among greenhouse gases, financial inclusion, and soft infrastructure. Conversely, significant negative correlations exist between financial risk, green growth, renewable energy, and technological innovation. An estimated 55% long-run variance is present. The study's key finding is that financial risk has an adverse effect on sustainable development, while an impactful relationship where increased green growth is linked to decreased GHG emissions. This association is notably significant. Results show that renewable energy has a negative coefficient and significant negative impact on greenhouse gases, showing an active relation to enhancing sustainable development. In contrast, financial inclusion has a significant positive effect on sustainable development. The implications imply that providing incentives to institutions engaged in alternative energy, precisely renewable sources, could positively impact the environment. Government policies and funding regulations oriented toward sustainable development are indispensable for environmental sustainability. Government policies and incentives are pivotal in advancing an environmentally conscious and sustainable future. This study's contribution lies in elucidating the positive correlation between government interventions and promoting renewable energy adoption, thereby paving the way for a greener tomorrow., (© 2024.
