Abstract:
There is a growing interest in electronic wastes (e-wastes) recycling for metal recovery because the fast depletion of worldwide reserves for primary resources is gradually becoming a matter of concern. E-wastes contain metals with a concentration higher than that present in the primary ores, which renders them as an apt resource for metal recovery. Owing to such aspects, research is progressing well to address several issues related to e-waste recycling for metal recovery through both chemical and biological routes. Base metals, for example, Cu, Ni, Zn, Al, etc., can be easily leached out through the typical chemical (with higher kinetics) and microbial (with eco-friendly benefits) routes under ambient temperature conditions in contrast to other metals. This feature makes them the most suitable candidates to be targeted primarily for metal leaching from these waste streams. Hence, the current piece of review aims at providing updated information pertinent to e-waste recycling through chemical and microbial treatment methods. Individual process routes are compared and reviewed with focus on non-ferrous metal leaching (with particular emphasis on base metals dissolution) from some selected e-waste streams. Future outlooks are discussed on the suitability of these two important extractive metallurgical routes for e-waste recycling at a scale-up level along with concluding remarks.

Abstract:
The paper focuses on the investigation of image processing of Electronic waste detection and identification in recycling process of all Electronic items. Some of actually collected images of E-wastes would be combined with other wastes. For object matching with scale in-variance the SIFT (Scale -Invariant- Feature Transform) is applied. This method detects the electronic waste found among other wastes and also estimates the amount of electronic waste detected the give set of wastes. The detection of electronics waste by this method is most efficient ways to detect automatically without any manual means.

Abstract:
"E-waste" is a popular, informal name for electronic products nearing the end of their "useful life. “Electronic waste" may be defined as discarded computers, office electronic equipment, entertainment device electronics, mobile phones, television sets, and refrigerators. "E-wastes are considered dangerous; ascertain components of some electronic products contain materials that are hazardous, depending on their condition and density. This includes used electronics which are destined for reuse, resale, salvage, recycling, or disposal. Others are re-usable (working and repairable electronics) and secondary scrap (copper, steel, plastic, etc.) to be "commodities", and reserve the term "waste" for residue or material which is dumped by the buyer rather than recycled, including residue from reuse and recycling operations. Many of these products can be reused, refurbished, or recycled in an environmentally sound manner so that they are less harmful to the ecosystem. This paper highlights the hazards of e-wastes, the need for its appropriate management and options that can be implemented.

Abstract:
In Malaysia, it is prevalent among many householders on accumulation of end-of-life electronics items at home and many are unclear of its disposal directive, which are likely to be disposed as household wastes. An insight into understanding their e-waste management practices and key predictors in relation to e-waste recycling intention are essential as they will lay the foundation for future effective e-waste management. This paper reports a preliminary exploration of the construct of e-waste recycling intention among householders. The data was collected from 150 respondents in Malacca, Malaysia. The results from this study showed that all the six dimensions generated are reliable with high intercorrelation among the dimensions. This implies that the measures can be used for further data collection to validate the study.

Abstract:
The main aim of this research was to assess the extent of the problems associated with inappropriate e-waste management and recycling practices. Electronic wastes (E-wastes) are generated from products that are designed for use with a maximum voltage of 1000 volts for alternating current and 1500 volts for direct current. These wastes contain hazardous materials such as lead, mercury, cadmium, brominated flame-retardants, valuable metals such as aluminium, nickel, copper, and certain precious metals such as gold, silver and platinum group metals (PGMs) which pose both human and environmental health threats. They have negative impacts on the health of workers and nearby residents; hence, residents of buildings located around and beside e-wastes dumpsites were randomly selected for this study. Well, run-off and borehole water samples as well as soil samples from different sites in Alaba international market, and Ikeja computer village in Lagos, Nigeria were analyzed for zinc, lead, iron, copper, nickel and chromium. Using additional information from questionnaires and interviews, impacts of e-waste dumps on the health of workers and residents near the study areas were investigated. The results were analysed using descriptive frequency count and tables which confirmed the presence of heavy metals in soils and water samples of the case study areas and hence appropriate recommendations were outlined to address the menace of e-waste disposal and as well as the need for improvement in e-waste management and recycling for economic opportunities and improved health standard within the Lagos Metropolis.

Abstract:
Rapid urbanization, advancements in science and technology, and the increase in tech-savviness of consumers have led to an exponential production of a variety of electronic equipment. The global annual growth rate of e-waste volume exceeds the growth rate of the human population. Electronic waste has now become a point of concern globally (53.6 million metric tons, 2019). However, merely 17.4% of all global e-waste is properly collected and recycled. China is the largest contributor to the global production of e-waste (~19%), the second being the United States. Indeed, only 14 countries generated over 65% of global e-waste production in 2019. E-wastes contain a wide range of organic, and inorganic compounds including various metals. Emerging contaminants like plastics are amongst the fastest growing constituents of electronic waste. The current challenges include the lack of reliable data, inadequate identification and quantification of new emerging materials, limited effectiveness of current recycling technologies, need for cutting-edge detection and recycling technologies, and the lack of e-waste management policies and international collaboration. In this review, we strive to integrate the existing data on production rates at different spatial scales, composition, as well as health, economical, and environmental challenges, existing recycling technologies; explore tangible solutions; and encourage further sustainable technology and regulatory policies.

Abstract:
Abstract This paper studied the recycling and the reuse of Municipal Solid Wastes (MSW) with Source Separation. These practices are commonly utilized in the European Union (EU) and internationally, giving successful recycling and treatment examples mainly for 7 selected - segregated household waste streams: a) paper and cardboard b) plastics, c) metals, d) glass, e) clothing and textiles, f) Waste Electrical and Electronic Equipment (WEEE) and g) Edible Oil Wastes (EOW). Greece implements lower recycling levels, 21%, of the annually produced MSW comparing to the EU. In 2021 the Regional Government of Attica launched a pilot program of rewarding recycling with Source Separation called “THE GREEN CITY”. This program consists of 60 Mobile Green Points (MGPs) that serve a unified citizen awareness and waste collection (7 MSW streams) network throughout Attica. This network includes numerous temporary parking and operation spots for the MGPs. A 56% of them is located next to recreation and green areas, registering at least 70,000 citizens in the program and collecting approximately 400 tons of clean recyclable MSW (April 2022). Therefore, “THE GREEN CITY” program serves the setting target of Directive 2018/851 for at least 55% by weight recycling and reuse of the Greek MSW by 2025.

Abstract:
The management of electronic waste (e-waste) mainly from televisions and computers, has turned into an environmental issue due to the increased demand in the electronics sector and the highly toxic contents (mercury, lead, or cadmium) of some of these devices that make them almost unrecoverable. Therefore, these valuable devices become wastes disposed of in landfills. Worldwide, some scholars have proposed recycling methods that re-introduce these wastes streams in the manufacturing process of heavy concrete, pavement, concrete blocks, and clay bricks among other unconventional products. The replacement rates of virgin materials with recycled e-waste fluctuate according to the type of waste. Nevertheless, the use of e-waste generates a positive environmental impact due to the less demand for virgin materials such as river sand and gravel. This study aimed to review the current e-waste recycling state-of-the-art such as circuit boards (PCB), high-impact polystyrene (HIPS), cathode ray tube (CRT), and LCD screens. A systematic review of scientific literature published in the last 10 years (2010–2019) was done through the SCOPUS database. The results showed a maximum potential replacement rate of 40% for this type of waste, given the effect on the physical and thermomechanical properties of the concrete.

Abstract:
The hierarchy of waste refers to the “3 Rs” i.e. Reduce, Reuse and Recycle, which implements the strategies of waste management according to their specifications in terms of waste minimisation. The power of solar was exposed to people when Jawaharlal Nehru National Solar Mission (JNNSM) was introduced in the country in the year 2010.From then on people started to install and set up the solar as they came to know that the end life of it is around to be 2035. But none of them thought about future, i.e. what would happen to the solar panels when they are not able to generate power. Now the main issue is how will India be able to discard nearly 90 GW worth solar panel in the next 20 years? Where an average solar panel sized 250 watts, 90GW will amount to almost 7.7 million tonnes of E- waste at the end of a lifetime of a solar plant [1]. This paper mainly focuses on how these E-wastes produced can be reused and recycled.

Abstract:
The construction industry has experienced rapid expansion in recent decades as a consequence of population growth, increased IT spending, increased industrialization, and the introduction of new infrastructure projects, all of which have resulted in a dramatic increase in the construction industry. As a result, the demand for building materials for construction operations is high, resulting in a large volume of construction trash. Wasted construction materials resulted in significant financial losses for builders, contractors, regional governments, and the country as a whole. The massive volumes of construction and demolition (C&D) waste created throughout the world, which account for more than 25% of all waste generated, has become a severe environmental concern that must be addressed. This analytical research study examines the many negative environmental effects of the currently utilized conventional waste management approach of landfilling and offers trash recycling as a viable alternative. Because of the vast volumes created and the tremendous potential for re-use and recycling reflected in these materials, the EC has designated construction and demolition (C&D) waste as a priority stream. Indeed, appropriate management would result in the effective and efficient use of natural resources as well as the reduction of the planet's environmental consequences. As a result, the Waste Framework Directive (WFD) requires Member States (MS) to take all necessary steps by 2020 to obtain the minimum target of 70% (by weight) of C&D waste for re-use, recycling, and other material recovery, including backfilling operational processes using non-hazardous C&D waste to replace other materials. As a result, this study on C&D waste is an important tool for determining the next stages and trends in the handling of this waste stream in Europe.

Abstract:
O intenso crescimento populacional traz consigo uma preocupação ambiental, já que, diante da necessidade de exploração dos recursos naturais, a adoção de políticas de reciclagem faz-se fundamental para alcançar o desenvolvimento sustentável. Neste cenário, apesar dos resíduos de construção e demolição (RCD) possuírem alto potencial de reciclagem, a estes sempre foi dispensado o tratamento de lixo. Além disso, os estudos realizados visando à reciclagem dos RCD mostram-se bastante concentrados na produção de agregados para a fabricação de concreto e para a aplicação em pavimentação. Diante disso, neste trabalho procurou-se definir uma nova aplicação para os resíduos de construção e demolição reciclados (RCD-R), buscando caracterizar suas propriedades geotécnicas como material de construção e verificando o seu desempenho como material de preenchimento de estruturas de solo reforçado. Ensaios de caracterização, de resistência ao cisalhamento e ensaios de arrancamento de geogrelha revelaram que o RCD-R apresentou baixos coeficientes de variação nas suas propriedades e excelente comportamento mecânico, o que justifica a sua utilização na aplicação proposta.
The intense population growth brings some environmental concerns due to the need of exploitation of natural resources, and the adoption of recycling policies is basic principle to reach sustainable development. In this scenario, however, the high potential of recycling the construction and demolition wastes (CDW) has been ignored. Moreover, studies focus mainly on the recycling of CDW for the production of aggregates for use in pavements and concrete. The present study deals with a new application of the recycled construction and demolition waste (RCDW) as backfill of reinforced soil structures. Characterization, direct shear and pullout tests on geogrids has depicted that RCDW shows low coefficients of variation of its properties and excellent mechanical behavior that justify its use for proposed application.

Abstract:
Do total de Resíduos Sólidos Urbanos gerados no Brasil, 51% são resíduos orgânicos dispostos em aterros sanitários ou lixões. A Política Nacional de Resíduos Sólidos integra as Políticas Nacionais do Meio Ambiente e da Educação Ambiental. Isso indica o reconhecimento do resíduo sólido reutilizável e reciclável como um bem econômico, de valor social, promotor de cidadania, gerador de trabalho e renda. O resíduo orgânico gerado na Universidade Tecnológica Federal do Paraná - UTFPR câmpus Curitiba, serviu como estudo de caso para avaliar o gerenciamento e tratamento de resíduos orgânicos utilizando a vermicompostagem e serviu como dinamizador da Educação Ambiental - EA para o ensino fundamental. Para o gerenciamento dos resíduos orgânicos em grande escala, como no Restaurante Universitário-RU da UTFPR, foi verificada a separação de resíduos na cozinha durante uma semana de resíduos crus, sobras do buffet e do prato. Os resíduos crus foram tratados em dois modelos de vermidigestores, um composto por caixas com o fundo modificado com furos e outro com barras. Os resíduos orgânicos crus mais gerados foram folhas de alface, repolho e cascas de pepino que formaram o substrato de alimento para os vermidigestores, e foram adicionados 10 kg de vermicomposto com 1,21 kg de minhocas da espécie Eisenia fetida por m2. O experimento foi planejado conduzido em 60 dias com uma aplicação de alimentação. A cada três dias foram retiradas amostras do vermicomposto e do lixiviado para analisar os seguintes parâmetros: temperatura; umidade; pH; quantidade de lixiviado; substâncias húmicas; coliformes; salmonella; relação C/N; macro e micronutrientes. Os resultados apresentaram temperatura média de 23ºC; a umidade média de 81%; o pH se manteve constante em 7,7; coliformes e salmonella foram encontrados abaixo do limite estabelecido e a relação média C/N no vermicomposto e do chorume foi de 10,8/1. A análise de micro e macro nutrientes indicou um fertilizante rico em nitrogênio e alta quantidade de ferro para os dois modelos. Observou-se que o modelo do vermidigestor com barras obteve melhor resultado quando avaliada a decomposição da matéria orgânica lábil, escoamento de lixiviado e reprodução da população de minhocas, sendo indicado para gerenciamento em grande escala. Para a aplicação em pequena escala, os dois modelos são adequados. A técnica da vermicompostagem foi aplicada em atividade de EA em escolas do ensino básico, as dificuldades e questionamentos dos professores, forneceram subsídios para o desenvolvimento de duas cartilhas: uma para o público infantil e outra para o público adulto.
Of the total urban solid waste generated in Brazil, 51% is organic waste disposed in landfills. The National Solid Waste Policy is part of the National Environmental Policy and articulates with the National Environmental Education Policy, and indicates the recognition of reusable and recyclable solid waste as an economic good, of social value, as a promoter of citizenship, a generator of jobs and income. The organic waste generated at the Federal Technology University of Paraná - UTFPR campus Curitiba, served as a case study to evaluate the management and treatment of organic waste using vermicomposting, which requires less space and serves as a promoter of Environmental Education - EE for teaching. For the management of large-scale organic waste, such as UTFPR University Restaurant-UR, the separation of residues in the kitchen was verified, the amount generated during a week of both raw and leftover waste from the buffet and dish. Two models of vermidigestors were used in duplicate, one consisting of boxes with the bottom modified with holes and another with bars. The most commonly generated raw organic residues were leaves of lettuce, cabbage and cucumber peels. Each of these vegetables was chopped separately to compose the food substrate, and to form the initial substrate that goes into the vermidigestores, 10 kg of humus were added with 1.21 kg of earthworms othe species Eisenia fétida per m2. The experiment was conducted in 60 days with only one feeding application. Samples of vermicompost and leachate were collected every three days to analyze the parameters temperature, humidity, pH, amount of leachate, humic substances, Coliforms, Salmonella, C / N ratio, macro and micronutrients. The results presented average temperature of 23ºC; The average humidity of 81%; The pH remained constant at 7.7; Coliforms and Salmonella were found below the established limit, and the mean C / N ratio in vermicompost and manure was 10.8 / 1. The analysis of micro and macro nutrients indicated a fertilizer rich in nitrogen and high amount of iron for both models. It was observed that the model of vermidigestor with bars obtained better result when evaluating the decomposition of the labile organic matter, leachate flow and reproduction of the earthworm population, being this model the one indicated for large scale management. For small scale application the two models are suitable. The box vermicomposting technique was applied in the EE activity from a primary school, identifying the difficulties and questions of the teachers, provided subsidies for the development of two booklets, one for the infantile public and another one for the adult public.

Abstract:
This thesis examines the regional electronic and electrical waste (e-waste) recycling network in Malaysia and Singapore, with a secondary focus on the articulations of informal labour within the network. I argue that there is a need to theorise production networks post-consumption; i.e. to focus on the activities and processes that occur after a commodity is consumed and subsequently discarded. I argue that discarded e-waste are not ‘value-less’ waste, but instead embody value (specifically latent use value), and have the potential to be re-inserted as ‘raw materials’ into production networks through the processes of recycling. Also, key to the processes of value (re)creation, enhancement and capture is the labour process. I examine informal labour by focusing on karung guni (a local term for the rag-and-bone man) – analysing their critical role in value (re)creation in this regional e-waste recycling production network through the lens of petty commodity production. I argue that karung guni are constitutive of this production network through their collection and primary processing of e-waste, which forms the basis for subsequent value creation, enhancement and capture by downstream actors. Conceptualising karung guni as petty commodity producers – who own both the means of production and their own labour power – is significant in problematising as not so straightforward the separation of capital and labour into discreet categories as normally presented in global value chains (GVC)/global production networks (GPN) approaches. This thesis makes four significant contributions to the GVC/GPN literature. First, it recognises activities beyond the point of consumption (which has been the focus of present GVC/GPN research). Second, it conceptualises the constitutive role of informal labour in the development and structure of production networks. Third, it emphasises the continued relevance of the state. Fourth, by adopting a multi-sited case study method, it contributes to debates on how to carry out GVC/GPN research.

Abstract:
Food waste has become a major concern around the world in recent years. Food waste is on the rise as the world's population grows. Despite the fact that various efforts have been made to reduce food waste, they have not been totally successful. Food waste is not only a loss for humanity, but it is also a loss for the environment, society, and economy. The majority of countries are attempting to manage, recycle, and repurpose food waste. A brief summary of waste reduction in agricultural methods, food processing, manufacturing, and retail distribution is provided in this context. Food waste generated at market centres, food services such as hotels and restaurants, and households, on the other hand, will be discussed. This research issue is mostly focused on nutrient recycling and tries to explore how to minimize, reuse, and recycle food waste as well as promote sustainable food waste management. Anaerobic Digestion is a promising solution for food waste management when compared to typical disposal methods such as landfilling, incineration, and composting. Anaerobic digestion is one of the most environmentally friendly and effective methods for food waste management and nutrient synthesis. Climate change mitigation, economic benefits, and landfill diversion are all advantages of anaerobic digestion of food waste. Biogas is the end product of anaerobic digestion. Biogas is a renewable energy source that can also be converted into biofertilizer. Carbohydrates account for 11.8-74 percent of biogas. The biogas yield for mono-digestion of food waste was 0.27-0.642m3 CH4/kg, and 0.272-0.859m3 CH4/kg for co-digestion of food waste. Because of its biodegradability and high water content, food waste is a substrate that can be handled by anaerobic digestion. As a renewable energy source, anaerobic digestion may be a preferable option. The by-product biogas, which includes 50-60% methane, can be used to generate energy and the final digested sludge can be used as fertilizer.

Abstract:
Cette thèse comprend trois expériences et deux prétests (N = 1135) dans lesquelles sont étudiés trois aspects fondamentaux du design statique des messages sur internet : son format (infographie, audio ou texte), sa couleur et sa typographie, sur la thématique du recyclage des déchets électroniques (études 1 et 2) puis à propos de la migration humaine (étude 3).L’étude des aspects graphiques est pertinente si l’on veut augmenter la force persuasive d’un message. Le format joue un rôle prépondérant (étude 1a), permettant à la fois de changer les attitudes, mais aussi d’ancrer ce changement dans le temps. Les couleurs, par contre, ne semblent pas faire varier la force persuasive du message ou amener les lecteurs à agir en faveur du recyclage (étude 1b). La typographie ne semble pas non plus jouer de rôle dans la dynamique persuasive, qu’elle soit jugée lisible ou peu lisible (étude 2). Des pistes théoriques concernant la personnalité des typographies et leur cohérence avec le contexte sont développées.L’analyse des composantes de l’ELM a révélé, dans chaque étude, le fort lien entre l’attitude des individus et leur sentiment de responsabilité personnelle envers la thématique abordée ainsi que leurs connaissances a priori. Nous avons également vu que les leviers de persuasion ne sont pas systématiquement les mêmes selon le besoin de cognition.Globalement, nous suggérons que les messages persuasifs doivent adopter un format permettant une analyse centrale à faible coût cognitif, utilisant une couleur principale et une typographie toutes deux lisibles et cohérentes avec la thématique développée, avec un argumentaire qui renforce le sentiment de responsabilité des lecteurs
This thesis includes three experiments and two pre-tests (N = 1135) in which three fundamental aspects of static message design on the Internet are studied: its format (infographics, audio or text), its colour and typography, on the theme of electronic waste recycling (studies 1 and 2) and then on human migration (study 3).The study of graphic aspects is relevant if we want to increase the persuasive power of a message. The format plays a major role (study 1a), making it possible to change attitudes and to anchor this change over time. Colours, on the other hand, do not seem to vary the persuasive force of the message or to lead readers to act in favour of recycling (study 1b). Nor does typography seem to play a role in the persuasive dynamic, whether it is considered legible or difficult to read (study 2). Theoretical approaches regarding the personality of typographies and their coherence with the context are developed.The analysis of the components of the ELM revealed, in each study, the strong link between the attitude of individuals and their sense of personal responsibility towards the theme addressed as well as their a priori knowledge. We have also seen that the levers of persuasion are not systematically the same according to the need for cognition.We suggest that persuasive messages should adopt a format that allows for central analysis at low cognitive cost, using a main colour and typography that are both readable and consistent with the theme developed, with arguments that reinforce readers' sense of responsibility

Abstract:
Abstract Over 40 million tons of electronic devices (e.g., computers, laptops, notebooks, and cell phones) became obsolete in 2020, and this estimate is expected to grow exponentially, mainly due to the decreasing lifespan of electronics. Most of the electronics replaced end up in municipal landfills. Electronic waste (e-waste) has raised concerns because many components in these products are not biodegradable and are toxic. Some of the toxic materials and chemicals include rare earth elements (REEs), which are currently experiencing supply constraints. This study focuses on generated e-wastes from households due to the high amount of these wastes. Technologies for e-waste mining must be tailored to household needs rather than large-scale industrial processes. The use of portable e-waste recovery systems may produce win-win outcomes where industry, households, and regulatory bodies could benefit, and this will incentivize e-waste mining for all stakeholders. This study investigates the sustainability benefits of employing a portable e-waste recycling and REEs recovery, using techno-economic and life cycle assessment methods. The results indicate that the proposed approach in this study mitigates environmental impacts when maleic acid is used as one of the key ingredients in recovering and separating REEs and other metals. It is concluded that when adopted globally, this technology can significantly address the e-waste challenge while improving the availability of REEs for high-tech applications.

Abstract:
In recent years, the waste mobile phones are generated in large quantity in China. Those e-wastes gain more and more attention because of both the sharp increase in quantity and the recyclable resources they contain. Furthermore, the mobile phone recycling industry has experienced a trend of rapid growth as well. However, due to the lack of national policies and legislations, the recycling industry is now facing problems in recycling processes. Thus in this paper, mobile phone recycling industry in China is systematically analyzed and a Cloud-based approach is developed which integrates tracking, interaction and coordinator mechanism through the recycling processes. With the integration of various stakeholders, the system can provide integrated data system throughout the whole life cycle of the mobile phones for the policy maker, and provide guidance for the operations during recycling service for the recycling stakeholders.

Abstract:
Abstract. E-Waste or Electronic waste is the broken pieces or junk or which is not used in present that is thrown out at the end of their lives. Generation of Electronic Waste is rising year by year due to the demand for newer electronic products which made the public to upgrade their technologies. The composition of plastics in Electronic Waste is high which is non degradable may cause consequential reaction. These wastes would contaminate in water, air, soil and also severely affect the humans and environment. Managing the Electronic Waste with tactical approach may create a way for sustainable waste management. For effective waste management process it is essential to adopt the 4R methods of Reduce, Recovery, Reuse and Recycle. Because it is significant to contemplate the health of the people and also by generating jobs in e-recycling field. In recent times the research is underway to examine the possibilities of using E-Waste in construction field. By adding the Electronic Waste as an alternative material to conventional material in bitumen for various percentages like 5%, 10%, 15%, 20% and 25%. Reusing the E-Waste plastic in aggregate form as certain or diverse forms probably low-budget and it is feasible in technical manner for disposing the huge E-waste. Replacing Electronic Waste in various forms in bitumen gives better strength than conventional bitumen.

Abstract:
Today, environmental economics examining the economic contribution of protecting the environment and natural resources and preventing the environmental pollution has become an important issue like energy. In this context the relationship between economy and environment is analyzed. In this relationship process of economy management change the environment and environmental qualifications take part in success of economy. Sustainable development, as an another important concept, explains realization of the efforts for economic growth and enhancing the welfare level in the meantime protecting the environment and people’s quality of life. Sustainable development has great importance for managing environmental, economic and social resources accurately. E-waste (electronic waste) management comes to the forefront in the context of environmental economics and sustainable development. Along with technological advancements and changing consumption habits e-waste management and e-waste recycling become crucial. While there are several related studies focus on waste management and recycling and their relationship between environmental economics and sustainable development few study deal with e-waste management. This study aims to fill this gap and make a contribution with emphasizing the importance of e-waste management for environmental economics and sustainable development. In this study e-waste practices in the World are evaluated, recycle ratios and their economic impact are examined, e-waste management’s importance as a financial trigger is emphasized, not only short term but also long term effects of e-waste management are elaborated from the point of sustainability and suggestions are discussed for improving the recycling processes for practitioners and law-makers.

Abstract:
Population growth, increasing prosperity and changing consumer habits globally are increasing demand for consumer electronics. Further to this, rapid changes in technology, falling prices and consumer appetite for better products have exacerbated e-waste management challenges and seen millions of tons of electronic devices become obsolete. This rapid literature review collates evidence from academic, policy focussed and grey literature on e-waste management in Africa. This report provides an overview of constitutes e-waste, the environmental and health impacts of e-waste, of the barriers to effective e-waste management, the opportunities associated with effective e-waste management and of the limited literature available that estimate future volumes of e-waste. Africa generated a total of 2.9 million Mt of e-waste, or 2.5 kg per capita, the lowest regional rate in the world. Africa’s e-waste is the product of Local and imported Sources of Used Electronic and Electrical Equipment (UEEE). Challenges in e-waste management in Africa are exacerbated by a lack of awareness, environmental legislation and limited financial resources. Proper disposal of e-waste requires training and investment in recycling and management technology as improper processing can have severe environmental and health effects. In Africa, thirteen countries have been identified as having a national e-waste legislation/policy.. The main barriers to effective e-waste management include: Insufficient legislative frameworks and government agencies’ lack of capacity to enforce regulations, Infrastructure, Operating standards and transparency, illegal imports, Security, Data gaps, Trust, Informality and Costs. Aspirations associated with energy transition and net zero are laudable, products associated with these goals can become major contributors to the e-waste challenge. The necessary wind turbines, solar panels, electric car batteries, and other "green" technologies require vast amounts of resources. Further to this, at the end of their lifetime, they can pose environmental hazards. An example of e-waste associated with energy transitions can be gleaned from the solar power sector. Different types of solar power cells need to undergo different treatments (mechanical, thermal, chemical) depending on type to recover the valuable metals contained. Similar issues apply to waste associated with other energy transition technologies. Although e-waste contains toxic and hazardous metals such as barium and mercury among others, it also contains non-ferrous metals such as copper, aluminium and precious metals such as gold and copper, which if recycled could have a value exceeding 55 billion euros. There thus exists an opportunity to convert existing e-waste challenges into an economic opportunity.

Abstract:
Population growth, increasing prosperity and changing consumer habits globally are increasing demand for consumer electronics. Further to this, rapid changes in technology, falling prices, increased affordability and consumer appetite for new products have exacerbated e-waste management challenges and seen millions of tons of electronic devices become obsolete. This rapid literature review collates evidence from academic, policy focussed and grey literature on the technical aspects e-waste value chains. The report should be read in conjunction with two earlier reports on e-waste management1. E-waste is any electrical or electronic equipment, including all components, subassemblies and consumables, which are part of the equipment at the time the equipment becomes waste. The exact treatment of Waste from Electrical and Electronic Equipment (WEEE) can vary enormously according to the category of WEEE and technology that is used. Electrical and electronic items contain a wide variety of materials. As a result of this complex mix of product types and materials, some of which are hazardous (including arsenic, cadmium, lead and mercury and certain flame retardants) multiple approaches to WEEE are required, each with specific technical guidelines. This report is structured as follows: Section two provides an introduction to the technical aspects of e-waste management, including a reflection on the challenges and complexities of managing a range of product types involving a range of components and pollutants. Section three provides an annotated bibliography of key readings that discuss elements of the technical aspects of managing e-waste. This bibliography includes readings on national guidelines, training manuals and technical notes produced by the Basel convention and courses. WEEE recycling can be a complex and multifaced process. In order to manage e-waste effectively, the following must be in place Legislative and regulatory frameworks Waste Prevention and minimisation guidelines Identification of waste mechanisms Sampling, analysis and monitoring expertise Handling, collection, packaging, labelling, transportation and storage guidelines Environmentally sound disposal guidelines Management is further complicated by the speed of technological advance with technologies becoming redundant much sooner than initially planned. Case studies show that the average actual lifetimes of certain electronic products are at least 2.3 years shorter than either their designed or desired lifetimes.

Abstract:
This master thesis explores the challenges for waste management business models in the field of textiles regarding the requirements of the circular economy, as well as improvement potentials in the current framework conditions. It is concerned with the research question: "Is it advisable to change the frame-work conditions at meso or macro level, with regard to business models for waste management companies in the textile sector that are oriented towards the requirements of the circular economy, and - if so - in what way?” The approach of the study is based on the delta analysis of the e Society for Institutional Analysis at the Darmstadt University of Applied Sciences. It compares the target state of the normative requirements with the actual state of the textile and waste management framework conditions and attempts to identify the gaps (the delta). Based on the delta, it develops approaches that are intended to help reduce the gaps. The thesis develops three business models for the target year 2025 in different areas: an exchange platform for sorters, recyclers and designers, an automatic sorting plant and a plant for fibre-to-fibre recycling of mixed materials. It is becoming clear that these business models cannot meet the target requirements for the circular economy. The analysis identifies the remaining gaps in the framework conditions as the main problem. For example, insufficient innovation impulses and the lack of competitiveness of secondary raw materials inhibit the actors from applying and using new technologies and business models. Restricted access to knowledge and information, as well as a lack of transparency between the actors, also prove to be problematic. In order to answer the research question, the study recommends altering the framework conditions at meso and macro level. It proposes a platform for cooperation between designers, the introduction of a material declaration system and an eco-design guideline for textiles as possible development options. In addition, this work offers a matrix of criteria to help the actors test and improve their new waste management business models regarding their suitability for the circular economy. The analysis is carried out from an outsider's perspective on the entire textile industry. It therefore cannot cover and deal with all aspects and individual circumstances of each player in detail. The necessary changes in the framework conditions that have been identified can therefore be used as a basis for further investigations.
