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.

Abstract Nickel nanoparticles supported by commercial carbon paper (CP) are prepared by pulsed laser deposition with deposition time of 3, 6, and 12 min as a catalyst for urea electro-oxidation. The surface conditions and the morphologies of the prepared electrodes have been characterized by Raman spectroscopy, scanning electron microscopy, and transmission electron microscopy. Urea electro-oxidation reaction in KOH solution on the Ni/CP electrodes is investigated by cyclic voltammetry and chronoamperometry. The results show that the electrode with less Ni nanoparticle agglomeration shows higher peak current density, which was achieved in the 3 min deposition samples when normalized by electroactive surface areas. However, the highest current normalized by the area of the carbon paper was achieved in the 6 min deposition sample due to the larger quantity of Ni nanoparticles. All the samples show good stability. Our results suggest that the low density, low cost, and environmental friendly CP can be used as support for Ni nanoparticle as a catalyst for urea electro-oxidation. It thus has great potential for many applications involving urea oxidation, such as wastewater treatments.

The paper industry is a high-carbon emission and energy-intensive industry. From the perspective of low-carbon trade and carbon neutrality, its energy conservation and emission reduction are worthy of attention. This study used the input-output model to calculate the embodied carbon emissions of China’s paper industry’s export trade to the United States from 2006 to 2020 and used the logarithmic mean division index (LMDI) method to analyze influencing factors of the change of embodied carbon emissions. The study found that the embodied carbon emissions of China’s paper industry’s export trade to the United States generally shows a stable downward trend after reaching the peak with the increase of export trade scale; scale effect is the main factor that causes the embodied carbon emissions, while technological progress, policy support, and environmental regulations are important driving forces to promote carbon emission reduction. The research results of this paper not only can test and guide China’s paper industry trade policies and industrial policies, but they can also provide decision-making reference for China and the United States to promote the carbon emission reduction of the paper industry.

5. Introducing the Concept of Energy: Educational and Conceptual Considerations Based on the History of Physics
- Author

Bussotti, Paolo
- Abstract
In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so Helmholtz's work, with several additions proposed here, is an excellent guide to understanding, from a qualitative point of view, the reasons that led scientists to establish the principle of conservation of energy. At the same time, it allows us to grasp two other concepts which are fundamental in reference to energy: work and heat. This panorama will be drawn in the first section. In the second one, some more mathematical and physical details on the teaching of energy in mechanics and thermodynamics will be offered. Finally, in the Conclusion, the interdisciplinary value of a historical approach to physics education will be pointed out. [For the full proceedings, see ED629086.]

Carbon is a wonder material and has served the mankind since the inception of civilization in a variety of ways. Among its different forms, carbon fibers are especially known for their conductivity and favorable strength to weight ratio. Here the development of PAN based carbon fibers embedded in a matrix material followed by pyrolysis to form a fibrous C/C composite has been discussed. The processing of carbon paper has been divided into four steps, with the product of each stage used separately for different energy applications. (1) Carbon fiber preform has been used as a filler to achieve high strength in bipolar plates for PEM Fuel cells (energy conversion). Flexural strength of nearly 80 MPa has been achieved as compared to 40 MPa of the commercially available Schunk plate, Germany. (2) Resin impregnated preform, i.e. the Green composite paper has been employed as an energy efficient heating element (energy conservation). This has been further fabricated as a room heater, which works at 500 cycles). The (4) Graphitized carbon paper has proved to be an excellent electrode (anode and cathode) backing material for PEM Fuel cell. 25% hike in the peak power density of unit PEM FC has been achieved while employing CNT incorporated NPL carbon paper as compared to while using Toray carbon paper of Japan and tested under similar conditions. This in turn is attributed to the unique properties acquired by the material with subsequent processing at each stage which has been discussed in detail.

7. Evaluating Visualization for Slide-Based Investigative Learning with Connection between Presentation Slides

Goto, Mitsuhiro and Kashihara, Akihiro
- Abstract
Presentation documents have been increasingly used not only as supplementary presentation materials but also as contents for investigative learning. In learning a presentation document, learners generally need to select a number of slides from the document, which describe what they want to learn or should learn. However, it is not so easy to find out the slides to be learnt since what each slide represents is not concisely stated and what connections exist between the adjacent slides are not explicitly expressed. They accordingly take more time for learning and finish learning with incomplete knowledge. In order to address this issue, this paper introduces a map called slidemap for visualizing the logical connections between the slides. This map helps learners identify the sequence of slides to be learnt from the presentation document and grasp the structure embedded in the document in a shorter time. This paper also demonstrates a tool for presentation slides-based investigative learning with slidemap. In addition, this paper reports a case study involving 16 participants with the tool, whose purpose was to ascertain whether using slidemap could be more beneficial for understanding the presentation document than using PowerPoint user interface. The results of the study show the effect of increasing learning time and visiting frequency for slides to be learnt, and promoting learners' understanding of presentation documents in a shorter time.

With the surging energy price and environmental concerns, measures to improve energy efficiency have attracted increasing concerns of the manufacture sector, especially energy-intensive manufacturing industries such as tissue paper mills. Energy-efficiency scheduling, as a novel energy-efficient method, has attracted the attention of an increasing number of researchers in recent years. Drying process is the most energy-intensive production process in tissue paper mills, which has a great energy-saving potential. This paper aims to reduce the energy costs for the tissue paper mill, consisting of processing energy cost and set-up energy cost, through integrating drying process optimization with energy-efficient scheduling. First, the energy cost model and the scheduling model were built. Then, the energy cost of the drying process of every job in a given scheduling problem was optimized using particle swarm optimization (PSO). Afterwards, the energy cost was further optimized using energy-efficiency scheduling. In addition, a hybrid non-dominated sorting genetic algorithm II (NSGA-II) was utilized to solve the energy-efficiency scheduling problem. Finally, several real scheduling problems from a real tissue paper mill were addressed using the proposed approach to demonstrate its effectiveness in energy saving. The experiment result showed that there is a great energy-saving potential in the drying process, accounting for up to 12.53% of the total energy consumption. Moreover, the maximum energy saving ratio of the proposed approach could reach 9.03%. On the whole, the proposed approach can provide a new energy-saving method for tissue paper mills or other manufacturing industries. [ABSTRACT FROM AUTHOR]

Abstract In this study, three-type paper supercapacitors based on the polyvinylidene fluoride (PVDF) and polyvinyl alcohol (PVA)/phosphoric acid (H3PO4) gel electrolytes and graphite nanoparticles (GNPs) electrodes have been fabricated. The gel electrolytes and electrodes films have been coated on the paper using push coating and then characterized by scanning electron microscopy (SEM). In two types of the paper supercapacitors, on the PVDF gel electrolyte film, a layer of PVA/water and BaTiO3 as a gel separator film has been coated. The specific capacitance of the paper supercapacitors using cyclic voltammetry (CV) and galvanostatic (charge–discharge) methods at the scan rates 20 and 150 mV s−1 have been investigated. The paper supercapacitor based on the BaTiO3 separator film showed higher specific capacitance (312 F g−1) compared to other samples. Also, using electrochemical impedance spectroscopy (EIS), the Nyquist and Bode curves of paper supercapacitors have been measured. For the paper supercapacitors based on the PVDF gel electrolyte film and BaTiO3 separator film using the Nyquist curves, the equivalent series resistance (ESR) was 306 Ω and 125 Ω, respectively. The paper supercapacitor based on BaTiO3 gel separator structure represents a new type of flexible supercapacitor with high performance that can be applied to electronic devices.

Renewable paper reusing plays a significant role in the sustainable environment under the background of the shortage in forest resources and the pollution from the paper industry. The conventional reusing stream of waste office paper appears to have low reusing rates while consuming massive amounts of energy in intermediate steps. In this study, we developed a novel portable renewable desktop paper reusing system based on font area detection and greyscale sensor. The proposed system consists of two main parts, namely, a greyscale sensor and font area detection model and a polishing mechanism. Acting as an ink mark detector for waste desktop paper, the greyscale sensor and font area detection model can detect the font in the waste desktop paper using an adaptive dynamic compensation schematic. The polishing mechanism will grind the font area of the wasted desktop paper, and this paper reusing processing is non-chemical, energy saving and environmentally friendly. The proposed system is demonstrated through simulations and experimental results, which show that the proposed renewable desktop paper reusing system is portable and is effective for reusing waste office paper in the office. An accuracy of 99.78% is demonstrated in the greyscale sensor and font area detection model, and the average reuse rate of one piece of paper is 2.52 times, verifying that the proposed portable system is effective and practical in renewable desktop paper reusing applications.

At present, there is no reliable method in use that unequivocally describes paper industry material flows and makes it possible to compare geographical regions with each other. A functioning paper industry Material Flow Account (MFA) that uses uniform terminology and standard definitions for terms and structures is necessary. Many of the presently used general level MFAs, which are called frameworks in this article, stress the importance of input and output flows but do not provide a uniform picture of material recycling. Paper industry is an example of a field in which recycling plays a key role. Additionally, terms related to paper industry recycling, such as collection rate, recycling rate, and utilization rate, are not defined uniformly across regions and time. Thus, reliably comparing material recycling activity between geographical regions or calculating any regional summaries is difficult or even impossible. The objective of this study is to give a partial solution to the problem of not having a reliable method in use that unequivocally describes paper industry material flows. This is done by introducing a new material flow framework for paper industry in which the flow and stage structure supports the use of uniform definitions for terms related to paper recycling. This new framework is termed the Detailed Wheel of Fiber. [ABSTRACT FROM AUTHOR]

PAPER industry , *ENERGY consumption , *CARBON dioxide mitigation , *CLIMATE change , *ENERGY conservation - Abstract
The pulp and paper industry accounts for approximately 5% of total industrial energy consumption and contributes 2% of direct carbon dioxide (CO 2 ) emissions from industries. World paper and paperboard demand and production are increasing significantly, leading to an increase in this sector's energy use and CO 2 emissions. Although current studies identify a wide range of energy-efficiency technologies that have already been commercialized for the pulp and paper industry, information is limited or scattered regarding new energy-efficiency technologies that are not yet fully commercialized. Development of emerging or advanced energy-efficiency technologies and their deployment in the market will be crucial for this industry's mid- and long-term energy saving and climate change mitigation strategies. This paper compiles available information on energy savings, environmental and other benefits, costs, and commercialization status for 25 emerging technologies to reduce the energy use and CO 2 emissions. The purpose is to provide a well-structured comprehensive review on these emerging energy-efficiency technologies for engineers, researchers, investors, policy makers, pulp and/or paper companies, and other interested parties.

Green Energy efficiency is becoming more important because of the resulting cost reduction and image of green society which helps to enhance competitiveness in a globalized green market. Pulp and paper manufacturing is a large-scale industry which is generally regarded as important for national development. The Pulp and Paper industry consumes approximately 2.5% of total industrial energy consumption in Thailand by 44 factories distributed throughout the country. Therefore, energy efficiency improvement can play a significant role in the industry. Investigations of the cost effectiveness of energy efficiency measures and technologies using bottom-up Conservation Supply Curve (CSC) in the pulp and paper mill process are required. This study examines the concept, methodology, and the usefulness of the energy conservation supply curve, and the potential to create the appropriate energy policies to the Thai Pulp and Paper Industry.

China's paper industry accounts for a larger proportion of the global paper industry and consumes large amounts of energy. Energy conservation and pollution reduction of the industry have become the focus of China's national development strategy. Energy efficiency is an important index which directly determines the amounts of energy consumption and pollution emissions. To understand the energy efficiency evolution of China's paper industry, this paper establishes an input-output data of the paper industry for 29 provinces in China and applies DEA method and econometric models to estimate and comprehensively discuss the energy efficiency issues based on the framework of total factor efficiency. Our results indicate that China's paper industry has a large energy saving potential even though its energy efficiency has improved during the period 1990–2013. The saving potential is about 65% under the meta-frontier and 44% under the group-frontier. Moreover, there are significant differences between different regions in production technology and energy efficiency. The performance of eastern China is better than other regions. But the technology gaps between the different regions are shrinking and converging over time. Finally, some policy recommendations are proposed to improve the energy efficiency of the industry.

The pulp and paper sector is one of the most energy-intensive industries in Morocco. This article aimed at identifying energy conservation opportunities at a Small and Medium-sized paper industry. The audit results together with their financial viability are presented regarding the analysis of energy consumption and electrical quality issues. The paper introduces an action plan for a more efficient energy use of some specific applications such as furnaces and compressed-air installations as well. The recommended energy efficiency measures have the potential of saving about 347.85 MWh of electrical energy and 101.78 MWh of thermal energy corresponding to reductions of 11.48% and 2.22%, respectively. The total investments related to the application of the action plan is approximately 290.53 kMAD and the global payback period does not exceed one year. It was also shown that a total quantity of 283.39 t of CO 2 emissions can be saved annually. [ABSTRACT FROM AUTHOR]

- Abstract
This study aimed at (i) identifying primary school students' attitudes toward environmental issues based on the perspectives of ecocentrism and anthropocentrism and (ii) inspecting students' attitudes (i.e., ecocentric and anthropocentric) toward environmental issues in relation to gender and grade level. Data were gathered from 40 students through the administration of an interview questionnaire along with pictures concerning questions in the questionnaire. Results demonstrated that most of the participants who held positive attitudes reflected anthropocentric attitudes toward water, paper, and electricity consumption, reusing, and playground preferences whereas ecocentric attitudes toward plants, bugs, and other animals. Besides, half and slightly more than half of the participants with positive attitudes expressed ecocentric attitudes toward residence preferences and environmental pollution, respectively while nearly half of the participants with positive attitudes expressed anthropocentric attitudes toward the mentioned issues. It was also found that with the exception of one environmental issue, participants' attitudes toward environmental issues were not significantly associated with their gender. Additionally, no relation was found between participants' environmental attitudes and their grade level.

Pulp and paper production, an energy-intensive process, is among the main light industries contributing to energy saving and pollution emission reduction in China. The improvement of energy efficiency is essential for energy consumption and sustainable development. This study analyzes the negative factors in the pulp and paper sector by calculating energy efficiency from the lengthways time and investigating the gap between China and foreign countries through a horizontal comparison. Accordingly, energy efficiency has increased in the Chinese pulp and paper industry with years of efforts, but its transformation remains unclear. Furthermore, the energy-saving potential, energy cost saving, and carbon dioxide emission reduction in the pulp and paper industry are evaluated according to the Twelfth Five-year Plan (2011–2015). The results show that the pulp and paper industry has further capabilities for energy-saving and carbon dioxide emission reduction by improving energy efficiency in China, resulting in great economic benefit. In brief, new technology and energy structure adjustment are long-term strategies for energy conversation, with changes in the scale of mills expected to provide huge opportunities to improve energy efficiency in China within a short period.

In the context of global climate change, energy conservation and greenhouse effect gases (GHG) reduction are major challenges to mankind. The forestry-pulp and paper industry is a typical high energy consumption and high emission industry. We conducted in-depth research on the energy flows and carbon footprint of the forestry-pulp paper industry. The results show that: (1) The main sources of energy supply include external fossil fuel coal and internal biomass fuel black liquor, which supply 30,057,300 GJ and 14,854,000 GJ respectively, in addition, the energy produced by diesel in material transportation reaches 11,624,256 GJ. (2) The main energy consumption processes include auxiliary engineering projects, material transportation, papermaking, alkali recovery, pulping and other production workshops. The percentages of energy consumption account for 26%, 18%, 15%, 10% and 6%, respectively. (3) The main sources of carbon include coal and forest biomass, reaching 770,000 tons and 1.39 million tons, respectively. (4) Carbon emissions mainly occur in fuel combustion in combined heating and power (CHP) and diesel combustion in material transportation, reaching 6.78 million tons and 790,000 tons of carbon, respectively. (5) Based on steam and electricity consumption, the indirect carbon emissions of various thermal and electric energy production units were calculated, and the key energy consumption process units and hotspot carbon flow paths were further found. This research established a theoretical and methodological basis for energy conservation and emission reduction.

Industrial sector is the largest user of energy in India and in many parts of the world. The pulp and paper industry accounted for 6% of total global industrial energy consumption, being the fourth largest energy consumer worldwide. For India, energy audit of a paper carton manufacturing unit was earlier reported with the following results. The specific electrical and thermal energy consumption was estimated as 91.85 kWh/ton and 1619 MJ/ton paper respectively. Annual energy saving potential was found to be 5.9% of the total annual energy consumption. With a view to identifying energy conservation and CO2 mitigation opportunities in writing, tissue, and craft paper production, this article presents energy auditing of a paper industry (Orient Paper Mills) in Amlai, Shahdol, Madhya Pradesh, India. The specific energy consumption of the typical paper industry in India was evaluated as 34.3 GJ per ton paper and specific CO2 emissions as 3.4 tons CO2 per ton paper. Some energy conservation opportunities for this industry were identified with significant energy saving (nearly 3.5%) and money saving potential with payback periods not exceeding 2 years in general.

Developing monitoring system for paper industrial wastewater treatment system is an important route for wastewater reuse and recycling from wastewater, which are regarded as effective way for cleaner production. A novel hybrid deep leaning CLSTMA model, which based on sequential fusion convolutional neural network (CNN), long short term memory (LSTM) and attention mechanism (AM), was developed to monitor the water quality in a full-scale paper industrial wastewater treatment system for energy conservation and emissions reduction. The hybrid CLSTMA model for predicting water quality of paper industrial wastewater treatment system was divided into three steps: spatial information fusion by using CNN module, temporal information fusion by using LSTM module and variable weighted calculation by using AM module. Compare with other models (CNN, LSTM and CLSTM models), RMSE of CLSTMA model for the effluent chemical oxygen demand (CODeff) reduced by 23.3–31.55%, MAE of CLSTMA model reduced by 38.89–74.50%, R of CLSTMA model increased by 8.29–11.86%. For the effluent suspended solids (SSeff), compared with CNN and LSTM models, RMSE of CLSTMA model reduced by 10.26% and 9.92%, MAE of CLSTMA model reduced by 5.37% and 3.44%, R of CLSTMA model increased by 15.13% and 37.21%, respectively. While, R of CLSTMA was consistent with CLSTM model, but RMSE and MAE of CLSTMA model reduced by 16.07% and 7.49% than the CLSTM model. Simulation results demonstrate that the proposed CLSTMA model has a great potential in monitoring paper industrial wastewater treatment system for cleaner production.

Summary: Due to the convenience of virtualization, the live migration of virtual machines is widely used to fulfill optimization objectives in cloud/edge computing. However, live migration may lead to side effects and performance degradation when migration is overused or an unreasonable migration process is carried out. One pressing challenge is how to capture the best opportunity for virtual machine migration. Leveraging rough sets and AI, this paper provides an innovative strategy based on Q-learning that is designed for migration decisions. The highlight of our strategy is the harmonious mechanism for applying rough sets and Q-learning. For the ABDS (adaptive boundary decision system) strategy in this paper, the exploration space of Q learning is confined by the boundary region of rough sets, while the thresholds of the boundary region can be dynamically adjusted by the reaction results from the computing cluster. The structure and mechanism of the ABDS strategy are described in this paper. The corresponding experiments show a firm advantage for the cooperation of rough sets and reinforcement learning algorithms. Considering both the energy consumption and application performance, the ABDS strategy in this paper outperforms the benchmark strategies in comprehensive performance. [ABSTRACT FROM AUTHOR]

Erdemir, Mustafe and Kandil Ingenç, Sebnem
- Abstract
This study aims to determine the influence of distance asynchronous teaching of Physics-I topics via intelligent tutoring systems (ITSs) on academic achievement and permanence. A Web-based learning environment was created by use of an ITS called "Turkish Intelligent Tutoring System" (TURKZOS) for such Physics-I units as work, energy, and conservation of energy. The experimental group of the study consisted of 26 students who had computer and Internet access and participated in the study voluntarily. The achievement test developed by the researchers was used for collecting data. This test was conducted as pre-test and post-test before and after the experimental procedure respectively. The same test was administered to measure permanence 45 days later following the performance of the post-test. The obtained data were analyzed via paired t-test. Mean pre-test score was found to be 23.88, and mean post-test score was found to be 73.80. Mean permanence test, on the other hand, was found to be 71.88. When mean pre-test and post-test scores were compared, a significant difference was identified in favor of the mean post-test score (p < 0.05). In addition, a significant difference was detected between mean permanence test and pre-test scores (p < 0.005). The mean permanence test score was higher than the mean pre-test score. It was concluded that intelligent learning environments created through Web-based tutoring systems have a positive influence on academic achievement and permanence in physics teaching.

- Abstract
Sustainable development is development that aims to improve the quality of life for all people around the world, both current and future generations. The focus and alignment of researchers on the theme of sustainable development is highly expected, as evidenced by publications in reputable journals, included in educational journals such as Eurasia Journal of Mathematics, Science and Technology Education (EJMSTE). The purpose of this Systematic Literature Review (SLR) was to review and compare investigations of researches on articles published by EJMSTE so that they are expected to have significant contributions to the topic of sustainable development. This SLR adopts five-step guidelines. The study standards that meet the requirements are, as follows: (i) the data used are from the 2005-2021 publication year; (ii) articles published in English; (iii) full paper can be accessed; and (iv) related to the theme of "sustainable" theme; and (v) only the type of research report articles. It can be concluded that EJMSTE is a pro-sustainable development journal. EJMSTE publishes 22 articles related to the theme of "sustainable". The most frequently used keywords are sustainable development and sustainability. Dominant authors were from Taiwan and China. We succeeded in formulating four important contributions made by articles published in EJMSTE related to sustainable themes, namely: (i) the urgency of science education in supporting sustainability, ESD, and SDGs funds; (ii) the need for curriculum reform and strengthening the competence of teachers in educational institutions, which are oriented towards sustainability and environmental literacy; (iii) the urgency of using technology that supports sustainability and ESD; and (iv) the urgency of energy efficiency, green marketing, green life cycle, and sustainable tourism to support sustainability. In addition, there are 22 useful educational resources that can be used as references/best practices, which can be implemented at the primary school to higher education levels.

Safari, Mahsa and Asadi, Somayeh
- Abstract
This paper outlines the result of an innovative program to develop a competency-based curriculum and a work process to engage students in energy assessment of small commercial buildings in their community. Throughout the resulting course, "Leadership in Building Energy Efficiency (LBEE)," students were trained to gather buildings' energy-related data and make recommendations for potential courses of action. The program facilitated energy assessment for 45 commercial buildings and supported the development of a retrofit plan with financing in place for nearly 30 of these projects. The purpose of this collaborative program was to advance building energy efficiency through the introduction of new methods and processes leading to financially viable energy retrofits of small commercial buildings. The program focused on assisting small restaurants, grocery stores and other food sales/services that are low-profit- margin and usually lack the ability to manage and finance energy efficiency improvements. As a result of this program, students got engaged in making long-term improvements in their communities. Additionally, they gained the real-world skills necessary to develop and execute energy retrofit projects for other customer segments as part of their careers. The program is broadening and scaling up to include other building use types and aims to be part of the development pipeline for energy retrofit projects in a way that develops students' capabilities, increases the knowledge of building owners and operators, and reduces the development costs of energy service firms and third-party financers.

Madhusoodanan, Harikrishnan and Vitus, Geetha Janet
- Abstract
A Green school is energy efficient, higher performing school that can be environmentally beneficial. Importance of Green school lies in the environmental friendliness value it upholds. Service learning has emanated out of philosophies of progressiveness and pragmatism. Service learning enables students to grow and learn through active participation in community service activities that are clearly connected to their academic program. (Bringle R.G., 1996) The "Haritha Vidyalayam" Project in Kerala is resonant with the Greening of schools adopted in the western countries in 1990's. The "Swach Bharat Abhiyan" can be entangled to service learning activities and green school projects because it's based on Article 51A. The probable question that shoots out of research is how the green schools are related to the service learning? The critical answer for this is the distant aim that both green school and service learning projects "the welfare of the community." The clubbing of society and the school can bring about a greater good for the environment through sustainable development. The Green school as an extended arm of service learning can cater to the needs of the school, society and each individual human being involved within. This paper elaborates upon the "Haritha Vidyalayam" project and steps to enhance green schooling as part of service learning.

Griswold, Wendy
- Abstract
We live in an era in which it is increasingly apparent that climate change is a threat to humanity. Worldwide, we are in need of professionals with the values, knowledge, and skills to implement solutions to the threat of climate change and other serious environmental issues resulting from humanity's current way of living on our planet. Efforts to create such professionals lack documentation of the longterm impacts of sustainability education. This presentation builds upon past research conducted with developing professionals during an undergraduate research experience (URE) focused on sustainable energy. Program participants from 2009-2014 were involved in a mixed methods study to explore impacts on their educational and career paths, involvement in sustainability careers, and evolving attitudes and perceptions of sustainability. Reporting on the qualitative portion of the study, key findings indicate that many past participants are working in sustainability-related careers and are all are actively engaged in sustainability roles that involve education and exemplify their leadership skills and dedication to the creation of sustainable societies. They are developing strategies to overcome the resistance they receive as sustainability-minded professionals. [For the full proceedings, see ED597456.]

43. From the 'Greta Thunberg Effect' to Green Conversion of Universities: The Reconstructive Praxis of Discursive Mobilizations
- Author
-
Feldman, Jonathan Michael
- Abstract
This paper investigates how one could envision a discursive mobilization process to transform protest movements into agents that help reconstruct the universities as agents supporting material mobilizations leading to ecological reconstruction. After reviewing universities' ecological footprints, the author shows how theories of mobilization and conjunctures could contribute to understanding how this transformation could occur. "Discursive mobilizations" advance values or ideas but stop short of innovation and production system changes. "Material mobilizations" affect deployment of human, technological, industrial and financial resources. "Conjunctures" involve linkages of political activity to spaces implicated in both kinds of mobilizations in a given historical time frame. The study shows many nations having both extensive climate activism and concentrations of university students creating a possibility for greening education centers based on various models for doing so. Yet, two key problems emerge. First, some nations lag in climate activism. Second, interest in a Green Deal or Green New Deal does not always match the level of attention to leading activist Greta Thunberg. The paper illustrates how such problems can be addressed by university-based campaigns linking activist cohorts, mobilization supporting green conversion of higher education and solidaristic, mutual aid exchanges among regions.

Kowasch, Matthias
- Abstract
This paper discusses the representation of resource exploitation and consumption in German geography textbooks. The aim of the paper is to contribute to a critical and reflective understanding of the representation of resource-related issues in textbooks by analyzing two scientific debates (resource curse and actor analysis). The paper shows that all studied geography textbooks contribute to a certain degree to awareness raising in Education for Sustainable Development (ESD), but references to the everyday life of students are rare. There are only few action-orientated tasks in the frame of resource exploitation and consumption in the studied textbooks. As real-world examples help develop students' critical thinking skills and shape their ideas of sustainable development, these aspects reflect a pedagogical shortcoming.

Albahlal, Abdulaziz
- Abstract
Environmental problems such as climate change, pollution, non-sustainable energy, resource depletion, and recycling Information Technology (IT) devices considered the biggest glitches which are facing developed and developing countries. IT devices have become a critical issue due to the great amount of environmental damage caused by IT companies from consumption of resources, raw materials, energy, and waste disposal. To tackle this problem, sustainability strategies have become crucial in Information Technology (IT) organizations--private and public. Sustainability and Green Information Technology (Green IT) have been introduced to reduce these environmental issues and increase the sectors' needs in a direction away from older IT. Green IT and sustainability aspects are essential to reduce the environmental damages that run rampant in developed countries such as Australia, USA, and the UK. However, in developing countries such as Gulf Cooperation Council (GCC) countries, China, and India, there are difficulties in applying Green IT models since they were introduced to meet the developed countries' needs especially in GCC. Currently, the organisations in GCC countries do not consider sustainability in their strategy to reduce the environmental impacts; however, GCC countries are causing a great deal of environmental damage due to their economic growth in different sectors such as oil, gas, and telecommunications. Furthermore, GCC countries are sharing the same policies to achieve the financial stability and change in the oil market. Thus, this research aims to develop a Green IT model for GCC in IT departments to reduce the environmental impacts. A mixed-methods approach will be employed to assess the GCC's needs and to examine the new model. [For full proceedings, see ED571459.]

SUPPLY chains ,WASTE recycling ,ENERGY conservation ,HIGH density polyethylene - Abstract
Although recycling is considered the core of a circular economy for returning materials to the supply chain, its procedures are poorly understood. Waste recycling is considered a big source of energy saving and a promoter of CO
2 recovery. Besides that, it generates jobs and changes markets worldwide. The Brasilian National Policy on SolidWaste (PNRS) recognizesWaste Pickers as the major social agent in the recycling process responsible for putting Brasil among the ten largest paper-recycling countries in the world. This paper presents an analysis of Brasilian recycling chains of paper and plastics and the main challenges for expanding recycling from Municipal solid waste. The research data were obtained from primary and secondary source related to the recycling supply chain of paper and of the following plastics--High Density Polyethylene (HDPE), Low Density Polyethylene (LDPE), Polypropylene(PP), Polyethylene Terephthalate(PET) and Polystyrene(PS). Enterprises of various sizes, including informal ones and WPs associations/cooperatives, were visited, in the five Brasilian geographic regions, during the years of 2013 and 2014. A nomenclature was defined for the various enterprises that operate in the Brasilian recycling chain. Each node of the plastic and paper recycling chain was described. The main bottleneck observed in these chains is the lack of continuous programs of selective collection with an emphasis on environmental education processes in the 5570 Brasilian municipalities. Several possibilities not only to promote waste recycling but also to increase the productivity of the sorting process are discussed. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Increasing the scientific knowledge of the population through education is a development strategy towards a sustainable future. However, there is no equity in the access to science education and scientific knowledge. The aim of this paper is to present and analyse a science kit named "Energy, Environment and Sustainability" (KEAS). Based on research conducted in Guinea-Bissau, it explores strategies to promote science education for a sustainable future. The strengths and limitations of the KEAS were studied using different data collection methods, including interviews, observation, survey, focus groups and document analysis. The participants were teacher trainers from the Guinea-Bissau School of Education. It is concluded that the KEAS is a feasible and suitable teaching strategy appropriate to the context, having the potential to contribute to learning about the environment and sustainability. Further, it addresses real problems for which students should acquire knowledge and skills in order to be able to make informed choices.

- Abstract
"Skill is laying the foundation for a brighter India. As John Ruskin puts it, "Skill is the unified force of experience, intellect, and passion in their operation." "Nation Building" is a herculean task that involves the government of the land, private and public institutions, industries, organisations, and every citizen there, holding accountability of its development inch by inch. India faces enormous problems in practically every aspect of national life as a young democratic nation with a multilingual, multicultural, and multiethnic population. Poverty, illiteracy, unequal and underdeveloped growth of diverse segments of the country, and insufficient infrastructure in educational and training institutions are all impeding the country's development. The insufficiently skilled workforce is unable to assume greater responsibilities in the development of a better nation. In India, there is now a scarcity of highly trained and skilled educators. Both in India and overseas, there is a considerable need for all levels of skilled labour, including semiskilled, skilled, highly skilled, and highly skilled with specialisation. An estimated 65 percent of workers in India are aged 15 to 59, with an average age of 29 compared to China and other OECD countries. Approximately 335 million people are currently employed in the United States today. They are largely uneducated and have little or no experience. Approximately 59 million of the 70 million predicted to enter the market will be in the 15 to 30 age category. For the development of our country, reskilling, up-skilling, and conceiving and generating ways and means for national and international labour mobility, as well as mitigating the low contribution of women labour force, are all critical. Our youth will be more competent if we place a higher value on skill development. To address all of the concerns of globalisation, knowledge explosion and distribution, and skill development competition, the Indian government has launched a number of initiatives, including Skill India, Digital India, Startup India, and Make in India. Many groups are attempting to improve people's skills. (a) Directorate General of Training (DGT), (b) National Skill Development Corporation (NSDC), (c) Indian Institute of Entrepreneurship (IIE), (d) National Skill Development Agency (NSDA), (e) National Skill Development Fund (NSDF), (f) National Institute of Entrepreneurship and Small Business Development, g) Skill Sector Councils, (h) ICT Academy, and respective State Skill Development Corporations. To impart and upgrade abilities, numerous organisations and universities offer a variety of certificate, diploma, and postgraduate diploma courses. TNOU also provides a variety of skill-based courses. The aspiration and ambition of the Indian Government is to make India the world's "Skill Capital." We/the editors consider it a privilege to have compiled this book titled "Nation Building through Skill Development," which contains contributions on a wide range of subtopics on various elements of skill development explored by a diverse group of authors from around the world. Choosing the chapters was, indeed, a difficult task. Original papers with less than 10% plagiarism were chosen for publication. For the publication of this book, forty-one essays were chosen. We/the editors would want to express our gratitude to everyone who submitted a chapter. The contributions that were not included in this publication are in no way considered rejects. We/the editors express our gratitude to Prof. Dr. K. Parthasarathy, Vice Chancellor, Tamil Nadu Open University, for entrusting us with this task. We/the editors would also want to express our gratitude to all those kind individuals who have worked tirelessly to bring this book in black and white.
