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]

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]

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.

This article discusses Conservation Units in the conservationist perspective, as instruments to protect nature, assuring the maintenance of Brazilian biodiversity and biomes, in order to build an ecologically balanced environment under the terms of the Federal Constitution of 1988. Through deductive method, exploratory, documental, and bibliographic research, and indirect analysis of Environmental Ministry and Environmental, Sustainable Development State Office data, it makes a legal-theoretical appreciation of the issue in Brazil. By looking at the Brazilian scenario, it notices that most part of the Conservation Units were created by the States and were focused, respectively, on Mata Atlântica, Cerrado, and the Amazon, and had sustainability as a legal-political fundament. The conjuncture of Goiás indicates that stating the Conservation Units existence is not enough, since more than half of Conservation Units lack landing regularization. Also, six out of twenty-five Conservation Units still do not have an Administrative Counsel. Twenty Conservation Units do not have a working plan, which, added to financial and staff difficulties may compromise the expected protection of nature. [ABSTRACT FROM AUTHOR]

Following the circular bioeconomy concept, this work studies the potential of an industrial wastepaper residue as an alternative raw material for dissolving pulp‐grade production. Prehydrolysis‐kraft cooking (PHK), elemental chlorine‐free (ECF) bleaching, and acid‐washing treatments were applied to achieve that aim. Considering the high lignin and hemicellulose content of the raw material, it was submitted to PHK pulping to enhance its cellulose content by removing those components. This processing resulted in a remarkable increase of 84 % in pulp Fock reactivity (from 45.6 % to 84.1 %). The dissolution extension and time in solvent systems LiCl/DMAc and NMMO/H2O were discussed regarding the pulp physicochemical properties. The dissolving pulp produced under this work showed great potential as raw material for textile applications, particularly highlighting the innovative process developed to improve its solubility.

The development of self-powered UV photodiode on green substrate is still a challenge. In this study, highly conductive Al doped ZnO (AZO) film was sputter-deposited on paper substrate at room temperature; subsequently, paper-based Schottky photodiodes were successfully fabricated by following Au-ZnO-Al and Au-ZnO-AZO-Al structure designs, respectively. These UV light-based devices operate successfully without external power. Au-ZnO-AZO-Al photodiode shows improved response and faster speed compared to Au-ZnO-Al photodiode. The one-dimensional Poisson simulation results demonstrate that the improvement is attributed to the strong electric field in the ZnO-AZO n-n+ high-low junction, thus, enhancing the collection rate and drifting speed of the photogenerated carriers. In addition, AZO can form favorable ohmic contact with the Al electrodes, further improving the device performance. The photo-response of the paper-based photodiode device shows high reproducibility and stability. Based on these outstanding results, we conclude that these paper-based electronic devices have great potential to replace conventional petroleum-based flexible electronic devices, thus, contributing to the green/sustainable development.

The recovery rate of paper products is a key factor in measuring the recyscling potential and the sustainability of the paper industry. Accurately measuring the recovery rate of paper products holds important theoretical and practical value. This paper took the non-recycling part and time factor into account and built the Koyck model to estimate the recovery rate, storage loss rate and recovery cycle of paper products. The model results showed that the recovery rate of Chinese paper products in 2017 increased to 58.05%, which was 10% higher than the results of methods that did not contain the non-recycling part or the time factor. The model results also showed that the storage loss rate of Chinese paper products was much higher than that of developed countries while the recovery cycle was close to the level of developed countries. The distribution analysis showed that the storage loss rate and recovery cycle of Chinese paper products varied significantly over time, which may be the result of policies and the change of consumption structure. It is suggested that the Chinese government should take measures to reduce the storage loss rate of paper products and enhance their recycling ability to achieve sustainable development.

The development of lignin-based admixtures (LBAs) for cement-based composites is an alternative to valorizing residual lignins generated in biorefineries and pulp and paper mills. Consequently, LBAs have become an emerging research domain in the past decade. This study examined the bibliographic data on LBAs through a scientometric analysis and in-depth qualitative discussion. For this purpose, 161 articles were selected for the scientometric approach. After analyzing the articles' abstracts, 37 papers on developing new LBAs were selected and critically reviewed. Significant publication sources, frequent keywords, influential scholars, and contributing countries in LBAs research were identified during the science mapping. The LBAs developed so far were classified as plasticizers, superplasticizers, set retarders, grinding aids, and air-entraining admixtures. The qualitative discussion revealed that most studies have focused on developing LBAs using Kraft lignins from pulp and paper mills. Thus, residual lignins from biorefineries need more attention since their valorization is a relevant strategy for emerging economies with high biomass availability. Most studies focused on production processes, chemical characterizations, and primary fresh-state analyses of LBA-containing cement-based composites. However, to better assess the feasibility of using different LBAs and encompass the multidisciplinarity of this subject, it is mandatory that future studies also evaluate hardened-sate properties. This holistic review offers a helpful reference point to early-stage researchers, industry professionals, and funding authorities on the research progress in LBAs. It also contributes to understanding the role of lignin in sustainable construction. [ABSTRACT FROM AUTHOR]

Paper-based analytical devices (PADs) enable the affordable, easy, rapid, and reliable detection of a range of analytes at the point-of-care. Cellulose is a versatile substrate for antibody attachment. However, how immunoreagents are immobilized onto cellulose plays an important role in assay performance. To provide an overview of the different antibody immobilization strategies used for developing PADs, we here critically review the existing literature from the last decade (2013–2023). First, we introduce cellulose as a substrate and summarize the different fabrication techniques for developing PADs. Thereafter, we delve into how antibodies are immobilized onto cellulose passively, covalently, or by affinity linkage. Affinity-based immobilization is further explored in a case study focused on using recombinant bifunctional proteins with cellulose-binding modules to anchor immunoreagents to cellulose. The final section discusses the validation and sustainable development of PADs addressing the existing and future challenges associated with developing such devices. [Display omitted] • Strategies for antibody immobilization onto cellulose substrates are reviewed. • Immobilizing antibodies in a site-selective manner improves analytical performance. • Cellulose requires modification before antibodies can be covalently attached to it. • Cellulose-binding modules facilitate antibody attachment onto unmodified cellulose. • Future challenges of developing sustainable paper-based immunoassays are discussed.

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 increasing pressure on natural resources and the climate has been noted by businesses and governments worldwide, who now face the difficult task of integrating paths of environmental sustainability and economic growth. One promising approach to sustainable development, reducing the pressure on natural resources and solving waste problems is circular economy. From different ways of implementing circular economy, this study focuses on the productization of industrial side streams, which carry a great deal of underutilized potential. In this article, the productization of pulp and paper industry side stream, fiber sludge, for commercial use as a dust-binding agent is studied via a descriptive, in-depth case study. Apart from inconsistent quality, fluctuating supply, cost of storage and logistics, what makes industrial side stream utilization challenging is the lack of knowledge that stakeholders have about side streams and their utilization and the lack of new value chain development for their commercial use. Therefore, it is essential for all parties involved to have a clearer vision of what is being sold for what purposes, through productization. This study found that the productization of side streams follows the same steps as the productization of any other traditional product, and the productized side streams can be added to the company's product portfolio as by-products.

• Index of recycling sustainability for assessing waste paper recycling. • Integrating methodology of GIS and value chain model. • Historical changes of informal recyclables distribution sites in Beijing. • Value chain of waste paper recycling in Beijing may face challenges in the future. • Policy implications to improve waste paper recycling in Beijing. China established a self-organized and market-driven recycling system, which was dominated by the informal sectors. In recent years, the amount of domestically-recycled waste paper grew slower than expectation in China, which may be resulted from a decline in economic sustainability of current recycling system. For understanding the waste paper recycling system in most cities in China, the economic mechanism remains unclear and the city-level data is extremely insufficient. In this work, an index of recycling sustainability (IRS, benefit divided by cost) is analyzed with a resolution of 1 km2 grid in Beijing City, by adopting value chain and GIS methodology. Five degrees of IRS are defined, from high-degree (IRS > 1.10) to low-degree (IRS < 0.95). Different stakeholders in the informal waste paper recycling system were interviewed to fill the data gap. Results show that: (1) from 2015 to 2018, the informal recycling of waste paper accounted for approximate 80% in Beijing; (2) the number of informal recyclables distribution sites decreased from 27 to 11, and their average distance to the city-center rose from 27.5 km to 40.9 km; (3) in 2015 and 2018, the grids with high-degree IRS accounted for 99.5% and 89.2%, respectively, indicating a sustainable waste paper recycling industry in Beijing; and (4) according to the scenario analysis, if the operating cost rises by 30%, the grids with low-degree IRS accounts for 98.5%, indicating a nontrivial challenges when the recycling cost keeps increasing in the future. Policy recommendations are put forward for a more sustainable paper waste recycling system in China. [ABSTRACT FROM AUTHOR]

Factors of manufacturing sustainability in the papermaking industry were identified and ranked using qualitative analysis and nonparametric tests. Based on a review of the literature on sustainable development and production, seven main factors of economic, environmental, technological, social, human, material and product, and regulations were identified to underpin the manufacturing sustainability in the papermaking industry, as well as some sub-factors. Then, a self-designed questionnaire was developed to take a poll among papermaking managers and experts regarding the effectiveness of the factors and sub-factors in manufacturing sustainability and their status. The factors affecting manufacturing sustainability in the papermaking industry were confirmed by the standard and significance coefficients in the structural equations and the predictive criterion. The cross-validated redundancy index showed that the data were valid enough for prediction. The research factors were ranked by the ordinal average affecting sustainability, current status, and distance to sustainability. The materials and product, environmental, technological, and economic factors had the greatest influence on manufacturing sustainability, and the regulation and human factors had the highest distance to sustainability. To achieve manufacturing sustainability in the papermaking industry, regulations and human factors need to be further studied. Their improvement has potential to achieve manufacturing sustainability.

Plastic-coated paper straws are insufficient to solve the plastic pollution problem because microplastics are formed during their degradation. In this study, upgraded paper straws were prepared by coating with biodegradable sodium alginate/cellulose nanofiber/stearic acid (SA/CNF/STA) on the surface of paper without additional adhesives. The tensile strength of the paper was enhanced synergistically by the coated SA and CNF after cross-linking with Ca2+ ions, reaching a maximum (26.46 MPa) when the mass ratio of SA to CNF was 4:1. The straws were prepared by spirally winding coated paper into tubes. Subsequent STA modification with different concentration (1–40%) improved the water stability of the paper straws. The paper straws exhibited excellent mechanical properties (including 13.45 MPa of flexural strength, 13.30 MPa of compressive strength) and hydrophobicity (103.67° of maximum water contact angle). After 130 days of soil burial, the paper straws were completely degraded. The comprehensive performance of prepared straws exceeds that of commercially available products in the same category, and they are safe and biodegradable. Paper straw in the work is in line with the concept of green and low-carbon development. [Display omitted] • Processing a paper straw based on biomass resource coatings. • SA/CNF hybrid coating synergistically enhanced the tensile strength of the straw. • The STA imparts satisfactory water stability to the straw. • The comprehensive performance of the straw outperforms commercial straw products.

The main rule included in IPPC directive (Directive 96/61/EC) obligating installation owners to operate in the sustainable way in order to reduce the impact on the environment. Water resources are limited, therefore many industries, in particular in water-stressed areas, must invest in water-saving programs. In particular, this problem applies to paper plants, which should limit their consumption of fresh water. However, the main environmental consequence in the production of pulp and paper refers not only to the consumption of water resources, but also to the emission of wastewater resulting from the production process. This paper focuses on the concept of sustainable management of water and wastewater. The proposed approach is demonstrated with a case study. The different treatment facilities option has been tested to find the optimal solution to minimalize consumption of fresh water and reduce effluent loads. The optimal water-wastewater configuration was found by testing several configurations. We concluded that striving for a nearly full circulation loop closure is not always justified by sustainable development and should be assessed in an integrated way. [ABSTRACT FROM AUTHOR]

China's rapid urbanization has led to the development of integrated transport networks, which requires the transport sector to pay particular attention to the integrated transport comprehensive carrying capacity (ITCCC). Concurrently, global climate change has focused the world community's attention on greenhouse gas concentrations like CO2. This study establishes an ITCCC measurement model of urban agglomerations (UAs) and measures the comprehensive carrying capacity from four factors: socio-economic, basic resources, transport facilities, and traffic environment. In particular, this paper takes carbon emission as a critical indicator of the traffic environment when considering the impact factors of ITCCC. Based on the data of China's five major UAs, this study estimates carrying capacity levels with the ITCCC model and analyses regional characteristics using the spatial-temporal differentiation method. The results show that the traffic environment significantly impacts the ITCCC. Further low-carbon transport policies and measures are recommended to achieve sustainable development of integrated transport in UAs. [ABSTRACT FROM AUTHOR]

Abstract Papermaking enterprises are currently under both environmental pressure and economic pressure for sustainable development in China. Thus, the efficiency, effectiveness, and benefits of resource utilization need to be improved. High-consumption and high-pollution companies should manufacture paper using sustainable methods. This study highlights a resource value flow analysis from the circular economy perspective, developing an extension of material flow cost accounting and modifying it by accounting for environmental damage as well as economic benefits. With reference to the Plan-Do-Check-Act cycle, this specific case study was conducted to verify the comprehensive utility of resource value flow analysis by establishing decision-making prioritization according to the dualistic diagnosis of "internal resource loss–external environmental damage costs." In general, applying a resource value flow analysis can both reduce resource consumption and minimize environmental damage, enhancing the sustainable development of a process industry with limited resources. Highlights • Material flows and value flows form an interactive unit in the resource value flow analysis model. • The resource value flow analysis model extends the environmental dimension of material flow cost accounting. • A dualistic diagnosis of "internal resource loss and external environmental damage costs" can achieve both economic profits and environmental benefits. • The Plan-Do-Check-Act cycle was introduced to strengthen the practical application of the resource value flow analysis.

The Guidelines on Building a Market-Oriented Green Technology Innovation System, which was released by China in 2019, has become a powerful signal to guide the development of green technology innovation (GTI). In the current digital strategy of China, the public media has become a key factor for promoting the transparency of enterprise environmental information. This paper measures the GTI efficiency of the listed paper enterprises in China as well as incorporating media attention into the research framework to explore the influencing factors of GTI of the listed paper enterprises in China during the digital economy era. The results showed that a positive media report had a positive impact on GTI and has become a new driving factor in promoting sustainable production in the digital era. Government support and openness also have a positive impact on GTI. However, negative media reports, environmental regulations, and technological innovation abilities have an inhibitory effect on the GTI efficiency of paper making enterprises. [ABSTRACT FROM AUTHOR]

The exponential growth of China's economy, coupled with the surge in online commerce, has led to a significant expansion of the logistics industry. In 2022, China's express delivery industry generated approximately 9 million tons of waste paper and 1.8 million tons of plastic. This study analyzed the current composition and utilization of logistics waste in China, with suggestions for recycling. Logistics waste can be defined as the packaging waste generated in the logistics industry. Corrugated paper and plastic waste were chosen as the objects for utilization. Due to its high cellulose content, corrugated paper can be utilized along with other paper waste for biomass resourcing. Biodegradable plastics can also be converted into biomass resources through the action of specific microorganisms. These polymers can be enzymatically depolymerized by certain bacteria and fungi, yielding valuable organic products. In general, logistics wastes all have potential for biomass resource recovery. By adopting appropriate recovery and conversion technologies, these waste streams can be transformed into high-value bio-based products, such as biofuels, biochemicals, and biopolymers, thus contributing to the development of a circular and sustainable economy.

Environmental pollution has become an important obstacle on the path of ecological civilization construction, and it is urgent to control environmental pollution. By establishing an evolutionary game model, this thesis focuses on analyzing how paper-making enterprises choose their own emission reduction strategies under the reward and punishment mechanism. It further analyzes how social welfare changes under the reward and punishment mechanism, and finally through simulation research, this thesis analyzes the evolutionary paths of paper-making enterprises' pollution emission strategies under the reward and punishment mechanism. The results of the reward and punishment mechanism are as follows: under the static reward and punishment mechanism, the game system will repeatedly oscillate around a point. There is no stable equilibrium point at this time. However, under the dynamic reward and punishment mechanism, the game system will tend to a stable equilibrium point. The results of social welfare analysis show that high-intensity rewards will reduce the amount of pollution discharged by paper-making enterprises, thereby maximizing social welfare. On the contrary, when paper-making enterprises discharge a large amount of pollution, they will be subject to high-intensity penalties. When facing high-intensity punishments, paper-making enterprises will tend to not to discharge. So social welfare is also maximized. The simulation research results show that reasonable punishment strategies are more effective than reward ones. Based on this, the author proposes countermeasures, such as establishing a reasonable reward and punishment mechanism, reasonably determining the reward and punishment intensity for polluting enterprises. The emission reduction strategies of paper-making enterprises will be affected by the government's reward and punishment mechanism. A deep study of its internal mechanism is not only of great significance for pollution control but also of great significance for the development of a green economy. [ABSTRACT FROM AUTHOR]

Guiding industries to produce in an effective and environmentally sustainable manner has become a key issue for governments around the world. Over the past 15 years, series of regional and industrial development policies have been introduced by the Chinese government. This has influenced the geographical distribution and energy efficiency performance of China’s industries. This paper quantifies the influence of enterprises geographical distribution on energy efficiency improvement in the paper industry and aims at providing some helpful suggestions on industrial development to policy makers. The main results show that, firstly, the paper industry in eastern China shows obvious characteristic of agglomeration. The average location quotient is 1.2278. However, following the industrial and regional development policies, the characteristic of agglomeration is weakening. Secondly, only when agglomeration reaches a certain level (location quotient is above 0.5447) will industrial agglomeration positively impact on industrial energy efficiency improvement (a 1% increase in agglomeration will increase dynamic energy efficiency by at least 0.23%). Thirdly, the regional development policies carried out by the government slow the pace of energy efficiency improvement in China’s paper industry. The empirical results indicate that the government needs to consider regional characteristics and consciously guide industrial enterprises to concentrate in the dominant area. [ABSTRACT FROM AUTHOR]

This paper reports the results of an exploratory experimental study to manufacture eco-friendly lightweight bricks through binary mix of paper mill sludge (PMS) and soil. The pre-manufacture activities include mineralogical, chemical, thermal and index properties characterisation of two kinds of soils (laterite and alluvial) and PMS. The mix ratio between PMS and soil was varied (0%, 5%, 10%, 15% and 20%) and two firing temperatures 850 °C and 900 °C were tested in order to emulate the typical conditions of a kiln. The performance of incorporating PMS into the mix was tested by evaluating properties such as linear shrinkage, compressive strength, water absorption, mass loss on ignition, and bulk density of bricks as recommended by the relevant Indian and ASTM standard codes. X ray diffraction results confirmed that the addition of PMS does not show any phase transformation and only enhances the porosity thereby leading to weight reduction. Based on the results, an optimum mix of 10% PMS with both soil types was found suitable for brick production at a firing temperature of 900 °C. Results obtained in this study will be helpful to brick industry for commercial production of PMS incorporated bricks leading to sustainable use of resources. [ABSTRACT FROM AUTHOR]

Our everyday lives are surrounded by green revolutions, environmental protection, sustainable lifestyles, sustainable development, and safeguarding our planet. Despite the fact that environmental challenges affect all human activities, few academic fields have written about them. Marketing is a good example. Businesses have begun changing their conduct to address society's "new" environmental concerns. Green marketing and environmental marketing are commonly used in the news. Many organizations in numerous sectors utilise green marketing to follow this trend. The American Marketing Association (AMA) defines „green marketing' as the promotion of ecologically friendly products. Thus, green marketing includes adjusting products, changing production processes, packaging, and advertising. Environmental Marketing and Ecological Marketing are synonyms. Changing to "green" may look costly initially, but it will pay off in the long term. Researchers can use this study to learn about green marketing, its importance, potential, and obstacles.

Twelve participatory paper maps by separate groups of men and women were facilitated by the High Atlas Foundation in six communities in Morocco between 2010–2020 as part of their process of participatory development. In this research, these sketch maps are analyzed for the first time. The twelve participatory paper maps underwent a gender-focused content frequency analysis. Seven communities were located using OpenStreetMap and Google Maps by a High Atlas Foundation expert. It was found that men contributed more overall geographic elements and written Arabic commentary than women, which could indicate a higher level of familiarity with their community and comfortability in communicating their opinions in writing. It was also found that there are many barriers to adding data from the sketch maps to OpenStreetMap due to language, loss of institutional memory, inconsistencies between the sketch maps of the same location, and inconsistencies between the sketch maps and satellite imagery.

By employing historical case study methodology, this paper examines the transition towards renewable energy and increased energy efficiency in the Swedish pulp and paper industry (PPI) during the 1970s and 1980s. Between 1973 and 1990, CO emissions were cut by 80 % in this sector, and this was mainly achieved by substituting away from oil to biofuels in the form of by-products from the pulp manufacturing process. The CO reduction was also a result of energy efficiency improvements and increased internal production of electricity through back-pressure turbine power generation. Sweden was highly dependent on oil at the advent of the first Oil Crisis in 1973, and the increased oil prices put pressure on the Swedish government and the energy-intensive PPI to reduce this oil dependency. Of central importance for the energy transition was the highly collaborative strategy of the PPI, both internally among pulp mills as well as between the sector as a whole and the corporatist Swedish state administration. The Swedish government chose a proactive strategy by emphasizing knowledge management and collaboration with the industry along with the substitution of internal biofuels for oil. The transition was also characterized by a strong focus on unutilized potentials in the PPI; a previous waste problem now could be transformed into energy savings and improved energy efficiency. Energy taxes and fees also played an important role in Swedish energy policy during the 1970s and the 1980s. All in all, the study illustrates the central role of governments and their ability to push industrial sectors into new technological pathways through a wide palette of mutually reinforcing policy instruments. The results further point at the importance of a more holistic understanding of the interplay between different policies and their impacts in the longer run. [ABSTRACT FROM AUTHOR]

In this study, a mathematical model has been developed for sustainable inventory, in which the effects of environmental factors on social factors, have been investigated. To this end, first, we revised Economic Order Quantity (EOQ) model by adding income from waste sales to this model. Next, considering the emission of sulfur oxides (SO x ), nitrogen oxides (NO x ) gases, Biochemical Oxygen Demand (BOD) and chemical oxygen demand (COD) indicators in waste water as a measure of water organic pollutants, we proposed a Green Economic Order Quantity (GEOQ) model. Then in order to examine interdependency between environmental aspects and social aspects, we introduced the sustainable model by adding environmental ergonomics in the terms of the effect of SO 2 emission on human health. Since the structure of the model consists of nonlinear objective function and linear constraints, the model could be solved based on an exact nonlinear constrained solution method. Finally, we examined the effectiveness of the proposed model demonstrated in a real case study of pulp and paper mill. Validation of the model was done by comparing the cost function of the proposed model with the pure economic model and the actual data. The results of study showed that proposed sustainable model plays a significant role in determining the order quantity and reduction of cost function, sulfur oxides (SO x ) and nitrogen oxides (NO x ) emissions, and Biochemical Oxygen Demand (BOD) and chemical oxygen demand (COD) in waste water.

The research and development of new products that could partially or completely replace raw materials used for energy production, high value-added chemical products, and even the production of paper, has allowed industrial hemp (Cannabis sativa L.) to become the main raw material for the reactivation of a bio-based economy with high production conditions and capacities. Based on this, the objective of this research is to deepen on the potential use of hemp fiber in the paper industry, supported by studies carried out by the Colombian State regarding the availability of forest crops for commercial purposes, which are basically used for planting and the production of wood resources such as pine and eucalyptus. It has been considered important to demonstrate that hemp, as a source of primary production, provides competitive economic, environmental, and social advantages over traditional crops, even for new sources of bio-based research.

Research on bio-based, fluorine free, and silane free superhydrophobic paper was of great significance in promoting the development of sustainable materials. Herein, we presented a facile and green method for fabricating superhydrophobic paper. First, a cellulose-based hydrophobic material (DAC-ODA) was synthesized by reacting dialdehyde cellulose (DAC) with octadecylamine (ODA) via a Schiff base reaction. Then, silica nanoparticles was used to enhance the surface roughness of the coating. The resulting coated paper exhibited superhydrophobic with a water contact angle of 155 ± 0.6° and a sliding angle of 4.1 ± 0.4°. Moreover, excellent repellent performances towards both cold and hot water were also observed.

As a traditional energy and carbon intensive sector, it becomes imperative for the global paper industry to realize green development. This paper aims to provide guidance for the green transformation of global paper industry by evaluating the global paper industry green development level in a systematic and dynamic way. This paper employs text-mining method to develop paper industry green development evaluation indicator system and adopts market-extended LCA model and entropy-TOPSIS method to calculate the paper industry green development level of 48 countries/regions. The results show that during 2000–2030 the paper industry green development level of developing countries improves faster than developed countries, where those of developing and developed countries increase from 0.3369 to 0.3938 and from 0.5120 to 0.5517 respectively and the gap between them narrows from 0.1751 to 0.1579. The comparative analysis reveals that the paper industries of developed and developing countries are in different green development stages. Developing countries, represented by China, improve greatly in economic and social dimensions, but decline seriously in ecological dimension due to enlarging resource consumption and environmental damages. On the contrary, developed countries tend to saturate in economic and social dimensions and have been improving fast in ecological dimension, gradually realizing the decoupling of industrial economic development and environmental damages. To further promote the global paper industry green development, developing countries should focus on promoting the coordinated development between economic growth and environment protection and developed countries should play a leading role in the global green transformation by promoting optimal allocation of resources and cross-regional communications of green technologies. • A paper industry green development indicator system is developed based on text mining. • A global paper industry green development model is built with market-extended LCA. • Complex interactions among the indicators are internalized in the evaluation. • A spatial-temporal analysis is performed on global paper industry green development level.

Pulp and paper mill biomass boilers generate large quantities of ash in Canada with British Columbia (BC) being the highest ash generating province followed closely by Quebec. Generally, the generated ash is landfilled, particularly in BC, with only a small amount being used beneficially. It is anticipated that the difficulty associated with the management of ash will worsen over time as the industry increases its reliance on green fuel. Thus, there is a strong need to identify beneficial uses of pulp and paper boiler ash for the sake of environmental and economic sustainability. The purpose of this report is to provide the first step in this direction, a review of proposed or implemented uses for coal and hog (or wood) ash around the world. Considering both the properties of the ash and local opportunities, this could be the first step toward screening the applications that may apply to individual mills. Several large-scale practices use ash, such as land application (as a nutrient source or as a liming agent), use in the construction industry (as a replacement for cement or as a fill material), and reclamation of mine sites and stabilization of unpaved forest roads. In some cases, relatively small-scale applications have been used which included uses such as a compost component, agent for pH adjustment of liquid streams and slurries, blasting abrasive, and source of quartz for glass manufacturing to name a few. It is important to note that the chemical nature of both fly and bottom ashes can be quite variable due to the type of wood residues combusted as well as combustion equipment used and must be considered in identifying beneficial applications. • General ash characterization is not enough to find useful applications of ash. • Ash use in the liming agent requires different properties than ash use in concrete. • Ash must be characterized according to its application requirements. • PPM ash can mainly be used for concrete, ag lands, liming agent, and forest roads.

This work presents the development of a green paper-based analytical device (Green-PAD) array for pH detection. The array was obtained with natural dyes extracted from red cabbage (Brassica oleracea) and butterfly pea flower (Clitoria ternatea); a filter paper was used as a substrate. The RGB indexes of the PADs' colors were extracted from the pictures taken using a smartphone or using a specifically developed RGB detector (Arduino-based) to obtain RGB indexes not affected by the light and the photocamera sensitivity. Multi-technique chemometric models were developed for calculating the pH value, starting from the RGB triplet of each sensing PAD. A preliminary and explorative chemometric analysis with PCA (partial component analysis) and TWPCA (3-way PCA) was carried out. Partial least square regression, PLS, was then applied to correlate the color of the PAD's picture with the solutions' pH. Different solutions at various pHs, ranging from 1 to 13, were obtained by titrating orthophosphoric acid with standardized NaOH, and they were used to create PLS models. Some real samples were examined as a test set, and the results were validated with pH-meter measurements. The ability of the PLS to model the experimental data was satisfactory since a good agreement between the experimental and fitted pH values was obtained. The proposed PADs were prepared with natural dyes and filter papers, so they are completely biodegradable and eco-friendly. Their fabrication does not require toxic or expensive reagents and sophisticated equipment. Also, the developed RGB detector, built-up with low-cost components and recycled batteries, adds value making the measurement cheap, easy and feasible also by non-expert people.

Low-quality materials contained in separately collected (SC) packaging waste generate environmental and economic burdens associated to both sorting operations of Material Recovery Facilities (MRFs) and landfilling of non-recyclable materials. In this study, based on quantification of both impurities and recyclable fractions, the quality of SC municipal packaging waste streams was determined by compositional analysis of the waste entering a MRF throughout a year. Foreign materials (% w/w) found in the monitored SC glass, paper plus cardboard and lightweight packaging waste, were on average 5.0, 14.7 and 23.0, respectively, while landfilled materials (% w/w) after MRF sorting operations were on average 4.3, 10.3 and 22.0, respectively. A Life Cycle Assessment study was conducted to determine the environmental impact of SC packaging waste streams quality of three different scenarios: current situation (CS), better (BS) and ideal (IS) scenario with reduced presence and absence, respectively, of improper materials in the three examined SC packaging waste streams. Emission of 32.1 kg CO 2 eq/t waste was calculated for the current situation with a reduction by 66.1% and 98.0% in CO 2 eq emission for BS and IS scenario, respectively. Similar emission reductions were calculated for ozone depletion, ionizing radiations, particle matter formation, fossil fuel depletion and primary energy demand impact categories. The environmental life cycle costing study demonstrated that total savings of € 35.2 and € 66.6 for each ton of SC packaging waste stream entering the MRF could be obtained for BS and IS scenario, respectively. [Display omitted] • Impurities in packaging waste streams generate environmental and economic burdens. • 23.0% of impurities were found in separately collected lightweight packaging waste. • Plant sorting operations generate 32.1 kg CO 2 eq for each ton of packaging waste. • € 35.2/ton of sorted packaging waste could be saved by reducing impurities content.

Rural communities face problems related to depopulation, lack of jobs, weak digital infrastructure, decline of basic public services. LEADER is an initiative to support rural communities, which takes shape in a Local Development Strategy with a role in using local resources in a way that meets the needs identified in the territory. The support of projects for smart villages must be encouraged through local development strategies that pursue various fields: reducing the depopulation of villages, providing quality services, developing local services, promoting digitization. The paper proposes the role that the LEADER intervention belonging to the Strategic Plan, which is one of the instruments of the European Union, can contribute to supporting these rural development projects, which can represent local initiatives and which can benefit from funding sources that will contribute to the identification of strategies and future solutions to promote smart villages. The information used in the work was collected, processed and interpreted starting from data belonging to the Bureau for the Financing of Rural Investments, along with insights from the Ministry of Agriculture and Rural Development, converge in a rich tapestry of thought at the paper's conclusion. Here, they weave forward-thinking strategies for the cultivation of smart villages, which are envisioned as vibrant oases capable of elevating the quality of life for rural dwellers. These innovative settlements promise to champion the cause of sustainable rural development, casting a verdant future where community and sustainability flourish side by side. [ABSTRACT FROM AUTHOR]

The paper presents the main trends of the Romanian honey market, in the period 2018-2022. In order to better highlight the evolution of this market, it was necessary to analyze specific indicators such as: total production of honey and the number of bee families both nationally and regionally; the price for honey at national level; consumption of honey per capita - average annual; quantitative exports and imports of honey from Romania. Complementary to the economic part, due to the fact that the honey bees are not only honey producers, but also vital natural pollinators, the paper also mentions and analyzes aspects related to the ethics of the beekeeping environment in Romania and EU, especially the use of neonicotinoids, in the context of global transformations.

The paper aims to comprehensively examine the critical role of rural development in the broader framework of achieving the Sustainable Development Goals (SDGs). Employing a robust mixed-methods research design, we explore global and regional rural development policies through a cross-cutting analysis. The primary objective is to uncover the profound and positive impact of specific interventions on critical SDG indicators, with a particular focus, on poverty reduction, improved access to education and healthcare, and significant progress in agricultural productivity. Our research uses a mixed-methods design, combining quantitative analysis, qualitative insights from community engagement sessions, and spatial analysis using GIS-based mapping. Preliminary results show a promising correlation between sustainable agricultural practices and meeting the SDGs, with a 30% reduction in food insecurity rates, while the qualitative insights indicate a notable increase in community cohesion and empowerment, highlighting the impact of rural development on well-being. Summarising these multi-faceted findings, our study highlights the symbiotic relationship between rural development initiatives and the SDGs. The imperative for context-specific and adapted strategies is evident from the spatial analyses, highlighting the need for a comprehensive, integrated and locally informed approach to achieve sustainable and equitable overall development. The paper advocates the recognition of rural development as a key driver for positive change in pursuit of the SDGs, providing valuable insights for policy makers, practitioners and researchers.

The power industry's low carbon transition is pivotal for achieving carbon reduction and sustainable development. This study uses the super epsilon-based measurement (Super-EBM) model and the Malmquist index to evaluate the power industry's low carbon transition efficiency using data from 30 provinces in China from 2010 to 2020, and utilizes the Tobit model to comprehensively analyze the factors affecting the low carbon transition of power industry. In addition, this paper examines the spatial differences in the power industry's low carbon transition efficiency as well as its distributional characteristics and dynamic evolutionary patterns. Conclusion is drawn as follows this paper analyzes the regional differences, spatial distribution characteristics and dynamic evolutionary trends of the power industry's low carbon transition. The main conclusions are as follows: (1) The power industry's low carbon transition efficiency in China shows an uptrend, with the western China region having the highest overall level of efficiency, greater fluctuations in the central China region, and more stability in the eastern China region, technological progress is a central factor in increasing total factor productivity, the efficiency of the power industry's low carbon transition is positively influenced by the electricity prices, and negatively influenced by the energy structure, environmental regulations and economic structure; (2) the Intraregional differences and hypervariable density are the main reasons sources of the overall differences in the efficiency of the power industry's low carbon transition; Intraregional differences in the eastern, central, and western China regions are decreasing year by year, but the efficiency of the power industry's low carbon transition in the western China region is still distributed in a multipolar way; (3) The dynamic evolutionary trends of the efficiency distribution of the low carbon transition in power industry is influenced by the type of spatial lag in the neighboring area. Where areas with low efficiency makes it difficult to achieve short-term leapfrog development, and areas with a cluster of high-efficiency provinces are prone to "Siphon Effect". The findings provide a theoretical basis for promoting the efficiency of the power industry's low carbon transition and coordinating the strategic adjustment of economic and environmental green development.
