Abstract:
The “Three Rs of Sustainability—Reduce, Reuse, Recycle,” are central tenets of many community waste-management programs promoting responsible use of natural resources and ecosystem services. Over the past few decades, recycling has become widespread, but monetary and energy expenditures required to transport and transform waste materials have led to downsizing of recycling programs globally and in the U.S. This trend increases the need for effective reducing and reusing practices as alternatives to recycling. Using a survey experiment to examine motivations that underlie reducing and reusing behaviors, individuals reported their current reducing, reusing, and recycling practices. Respondents then were provided with three hypothetical scenarios that described (1) an external waste-management threat to public well-being, (2) social/peer pressure from family and friends towards sustainable decision-making, and (3) increased convenience of reusing and reducing practices. These messages reflect previously identified RRR motivations. After the scenarios, the questions regarding recycling, reducing, and reusing behavior were presented again to test for changes in the responses. All three scenarios were effective in increasing intended reducing and reusing behavior. The threat scenario was slightly more effective than the others, particularly among individuals who reported behavior with considerable recycling practices but not as much reducing and reusing.

Abstract:
According to the Ellen MacArthur Foundation, 73% of used clothing is landfilled or incinerated globally and greenhouse gas (GHG) emissions from fabric manufacturing in 2015 amounted to 1.2 billion tons. It must be reduced in the future, especially by reusing and recycling used clothing. Based on this perspective, researchers calculated the energy consumption and GHG emissions associated with reusing and recycling used clothing globally with a life cycle assessment (LCA). However, no study was conducted so far to estimate the total GHG emission reductions in Japan by reusing and recycling used clothing. In this study, the amount of used clothing currently discharged from households as combustible and noncombustible waste and their fiber types were estimated using literature. Then, the methods for reusing and recycling of used clothing were categorized into the following 5 types based on fiber type, that is, “reuse overseas,” “textile recycling to wipers,” “fiber recycling,” “chemical recycling” and “thermal recycling.” After that, by applying LCA, the GHG emission reductions by above 5 methods were estimated, based on the annual discharged weights of each fiber type. Consequently, the total GHG emissions reductions by reusing and recycling 6.03 × 108 kg of used clothing totally were estimated around 6.60 × 109 kg CO2e, to range between 6.57 × 109 kg CO2e and 6.64 × 109 kg CO2e, which depended on the type of “chemical recycling.” The largest contribution was “reuse overseas,” which was 4.01 × 109 kg CO2e corresponded to approximately 60% of the total reduction. Where, it was assumed that used clothing were exported from Japan to Malaysia which was currently the largest importing country. In this case, GHG emissions to manufacture new clothing in China, the largest country currently to export them to Japan, can be avoided, which are 29.4 kg CO2e and 32.5 kg CO2e respectively for 1 kg jeans and 1 kg T-shirts. Adding the GHG emissions for overseas transportation to this, on average, 32.0 kg CO2e per kg of used clothing was reduced by “reuse overseas,” which was 19.6 times larger than GHG emissions by incineration, 1.63 kg CO2e per kg, in which carbon neutrality for cotton was not counted. As the result, the total GHG emission reductions above mentioned, around 6.60 × 109 kg CO2e, corresponds to 70% of the GHG emissions by incineration of total household garbage in Japan.

Abstract:
It is important to manage reverse material flows such as recycling, reusing, and remanufacturing in a production environment. This paper addresses a production planning problem which involves reusing of scrap and recycling of waste that occur in the various stages of the production process and remanufacturing/recycling of returns in a closed-loop supply chain environment. An extended material requirement planning (MRP) is proposed as a mixed integer linear programming (MILP) model which includes—beside forward—these reverse material flows. The proposed model is developed for the jewelry industry in Turkey, which uses gold as the primary resource of production. The aim is to manage these reverse material flows as a part of production planning to utilize resources. Considering the mostly unpredictable nature of reverse material flows, the proposed model is likewise transformed into a fuzzy model to provide a better review of production plan for the decision maker. The suggested model is examined through a case study to test the applicability and efficiency.

Full text
Abstract:
Over the last decades, the use of glass fibre reinforced thermosets (GRT) has become widespread and commonly used in many sectors. Currently no commercial recycling process exists for GRT and the amount of waste generated has reached an unsustainable level. The value of recycled glass fibres (RGF) is reduced significantly due to loss in strength and surface functionality during recycling. Thermal recycling processes involve decomposing the polymer matrix at elevated temperatures to recover the reinforcement fibres. Exposing to such high temperatures degrades the strength of the fibres as well as removes the sizing on the fibre surface. The focus of this thesis is to investigate the potential for retaining and regenerating the strength and interface properties of thermally recycled glass fibres; in order to produce composites reinforced with RGF that could complete with those using virgin/pristine glass fibres. In order to recycled GRT in-house, a lab scale thermal recycling system based on a fluidised bed reactor was initially designed and developed. To build on the already extensive research into this recycling process, this thesis aims to reduce the temperature required to recycle GRT within the fluidised bed by introducing a metal oxide catalyst to aid in the thermal decomposition of the thermosetting matrix. This novel line of research was selected due to the potential for reducing both the energy consumption of the recycling process and thermal damage sustained by the glass fibres during recycling. Using thermogravimetric analysis it was found that copper (II) oxide (CuO) was particularly active at catalysing the thermal decomposition of epoxy, reducing the decomposition temperature by up to 125 °C. When used within the fluidised bed recycling process, CuO facilitated recycling of glass fibre from glass fibre reinforced epoxy (GF-EP) at just 400 °C without compromising on fibre yield efficiency. Another avenue of research in this thesis was assessing the potential of a variety of chemical treatments to regenerate the strength and surface functionality of thermally recycled glass fibres. It was found that soaking in hot NaOH solution could provide approximately a 130% increase in the strength of RGF; concluding that changes to surface morphology due to etching was the re-strengthening mechanism. The interfacial adhesion between RGF and 1) polypropylene (PP) and 2) epoxy were examined. It was found that the interfacial shear strength (IFSS) between RGF and epoxy could be fully restored by first treating the RGF in NaOH solution. Regenerating the IFSS between RGF and PP proved more challenging despite the use of fibre sizing and PP matrix modification. GRP reinforced with RGF (with and without regeneration treatments) were prepare and mechanically characterised; however, the GRP exhibited significantly poorer mechanical properties than those prepared with virgin fibres. This drop in performance was typically attributed to a combination of 1) lower fibre strength, 2) poor fibre-polymer interfacial adhesion and 3) low fibre volume fraction within the GRP.

A indústria de blindagens, seja ela com finalidade civil ou militar, utiliza em seu processo produtivo diversos materiais de interesse científico. A busca por produtos cada vez mais leves e com melhor desempenho balístico tem sido tema de estudos há vários anos. No entanto, pouco se tem observado em relação à questão da preservação ambiental, seja no próprio ciclo de vida do material ou de simples condutas responsáveis por parte dos fabricantes e consumidores. Sendo assim, o objetivo desse trabalho foi avaliar a possibilidade de reutilização e/ou reciclagem do policarbonato utilizado em blindagens automotivas e arquitetônicas, observando se foram preservadas as características indispensáveis para sua finalidade original, como transmitância, resistência à tração e resistência ao impacto. Foram utilizadas amostras de policarbonato submetidas a diferentes técnicas de separação do conjunto balístico original, a fim de observar a influência da técnica de separação sobre as propriedades ópticas e mecânicas do policarbonato. Também foi avaliado o comportamento do policarbonato após repetidos ciclos de autoclavagem, já que esta técnica tem sido muito utilizada em serviços de recuperação de vidros blindados delaminados. Para avaliar os efeitos das técnicas de separação de autoclavagem, utilizaram-se as técnicas de microscopia eletrônica de varredura, ensaio de tração, análise dinâmico-mecânica e espectroscopia no ultravioleta e no visível. Os resultados demonstraram entre os principais fatores que degradam o policarbonato podemos destacar a exposição prolongada ao ultravioleta, exposição a solventes como álcool isopropílico e acetona.
The shield industry, for civil or military purposes, use in its process of production, many different materials of scientific interest. The research for lighter and better ballistic-performance products have been studied for many years. However, not much have been observed in relation to the environmental protection issue, whether it is in the own material life spam or simply, the responsible behavior by manufacturers and consumers. Therefore, the goal of this work was to measure the possibilities in reuse and/or recycling of polycarbonate used in shielding for cars and architectonics, observing if the essential characteristics were preserved to its original intent, like transmittance, tensile strength and impact resistance. Polycarbonate samples were submitted to different separation techniques from the original ballistic set, in order to observe the influence of the separation technique over the optical and mechanical properties of polycarbonate. It was also measured the polycarbonate s behavior after several autoclaving cycles, since this technique has been very much used in the recovery of delaminated shields. In order to measure the autoclaving separation techniques, it was used surveillance of electronic microscopic techniques, tensile essay, mechanical- dynamic analysis and visual ultra violet radiation spectroscopy. The results have shown that among the main factors that degrade the polycarbonate it is able to highlight the long-term exposition to ultra violet radiation, exposition to isopropylic alcohol and acetone solvents.

Kiwala, Kathleen L. "A Model to Predict Recycling Behaviors: Reusing Ajzen's Model One More Time." PDXScholar, 1993. https://pdxscholar.library.pdx.edu/open_access_etds/4607.

Full text
Abstract:
The prediction of self-reported recycling behaviors was examined using variations and expansions of Ajzen's theory of planned behavior. Three hundred and forty-eight residents from the Multnomah, Clackamas and Washington counties in Oregon completed a questionnaire that assessed attitude, subjective norms, perceived behavioral control, intentions, self-reports of recycling behavior, moral obligation and past behavior. Recycling behaviors and intentions were grouped into three categories of difficulty by a factor analysis. Structural equation analysis did not support Ajzen's model. It was found that although attitudes was correlated with the antecedent variables, it did not directly influence intentions or behaviors. Perceived behavioral control had the largest direct influence on behavior. Subjective norms had the greatest direct influence on intentions. Past behavior, as measured, was not significantly related to any variable in the model. The inclusion of moral obligation added significantly to the ability to predict recycling behavior. Moral obligation directly influenced subjective norms, attitude, perceived behavioral control and behavior. The results suggest that programs that aim to increase recycling behaviors should focus on: the community good as the motivation for recycling, the impacts of the individual's recycling behavior on community resources, the "how to's" of recycling, and supplying services and information about those services.

Abstract:
Urban sprawl, global warming and overused landfills are conditions around the world today, and while people are concerned about these issues they have few practical solutions to them. This creative project seeks to devise a way for a specific sector of business (restaurants), to have a practical way to help reduce global warming and waste while utilizing unused or under-used land in urban areas. While life cycle models are available that address such issues as these, very few case examples are actually in use in this country. Based on existing life cycle models, this project will seek to reuse the wastes from a restaurant and recycle them into a garden/greenhouse (called an urban farm throughout this paper) which will produce food for the restaurant. The three main waste categories from the restaurant to be looked at are the organic kitchen food wastes, water and the heat that is always being expelled from the kitchen while it is operation. Additional ways to make a restaurant more sustainable will also be given. This project will show what the benefits are when a sustainable system is in operation.

For sequences of related linear systems, the computation of a preconditioner for every system can be expensive. Often a fixed preconditioner is used, but this may not be effective as the matrix changes. This research examines the benefits of both reusing and recycling preconditioners, with special focus on ILUTP and factorized sparse approximate inverses and proposes an update that we refer to as a sparse approximate map or SAM update. Analysis of the residual and eigenvalues of the map will be provided. Applications include the Quantum Monte Carlo method, model reduction, oscillatory hydraulic tomography, diffuse optical tomography, and Helmholtz-type problems.

Full text
Abstract:
Relatively high enzyme loadings are required for the bioconversion of lignocellulosic biomass, impeding the economical production of cellulosic sugars. The relative stability and robustness of these enzymes make enzyme recycling an attractive cost-reduction strategy. However, the efficiency of enzyme recycling has been limited by the complexity of enzyme-substrate interactions, which are influenced by enzyme, substrate, and physical factors. A lack of techniques to probe specific enzyme adsorption further limits our understanding of these interactions. Therefore, overcoming these challenges to better understand enzyme-substrate interactions is crucial if we are to improve the effectiveness of enzyme recycling strategies. Initial work compared various ways to assess enzyme adsorption during hydrolysis of steam pretreated corn stover (SPCS) using a complete commercial cellulase mixture. While the distribution of six individual enzymes could be followed, the initial approach used was laborious, highlighting the limitations of techniques used to quantify individual enzyme adsorption profiles. A quicker, more sensitive double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was subsequently developed, to follow Cel7A, Cel6A, and Cel7B adsorption during hydrolysis, and shown to agree with earlier results. As enzyme, substrate, and physical factors were known to affect enzyme recycling performance, their influence on individual enzyme adsorption was evaluated. Although the lignin present in the SPCS did not appear to influence enzyme adsorption (although Cel6A adsorbed more readily to the lignin-containing SPCS), cellulose allomorphs and crystallinity did appear to influence enzyme adsorption. The addition of Auxiliary Activity (AA) family 9, an oxidative enzyme, increased desorption of Cel7A, likely by increasing the substrate’s negative charge. The AA9 itself remained primarily in the supernatant, which highlighted the importance of recovering enzymes from both the liquid and solid phases of the reaction. The influence of glucose and ethanol on enzyme adsorption was evaluated, and a reduction in enzyme adsorption was observed at high glucose but not ethanol concentrations. When the addition of fresh substrate was assessed as one way to recover enzymes, by combining enzyme recycling at low glucose concentrations with enzyme supplementation, good overall cellulose hydrolysis (~70%) over 5 rounds of enzyme recycle could be achieved with a 50% reduction in enzyme loading.

S’adressant au difficile problème de l’élimination des déchets de téléphonie mobile, basée sur le concept de création de valeur partagée, de l’économie circulaire et de la chaîne d’approvisionnement verte, cette thèse a d’abord été démontrée dans des cadres théoriques et par la revue théorique de la littérature, puis a mis en avant l’idée et la méthode pour construire un système de recyclage de déchets de téléphone mobile basé sur ces théories. Pour faciliter le recyclage des déchets de téléphonie mobile au niveau pratique en Chine et dans d’autres pays, les problèmes existants et le mode de fonctionnement sont résumés, et l’espace d’utilisation des déchets de téléphonie mobile est élargi. Une analyse quantitative est appliquée pour examiner les indicateurs d’évaluation pertinents et les modèles mathématiques au niveau analytique. Cette thèse a principalement utilisé les quatre types de méthodes de recherche suivants: processus de hiérarchie analytique, analyse empirique, analyse quantitative et qualitative, ainsi qu’une intégration de l’analyse au niveau macro et micro. Grâce à ces méthodes de recherche, cette thèse a fait une analyse détaillée et une discussion sur le statut de recyclage, les facteurs influençants, l’effet d’utilisation, le système d’index d’évaluation complet, ainsi que les lois et réglementations pertinentes de gestion des déchets de téléphonie mobile. Après une analyse détaillée, la thèse a conclu que même si les preuves ont montré que les déchets de téléphones mobiles causent une pollution grave à l’environnement, une énorme quantité de valeurs économiques subsistaient pourtant dans les déchets des téléphones mobiles. Les faibles taux de recyclage et de réutilisation des systèmes pourraient être renforcés premièrement en améliorant le mécanisme économique basé sur les théories de l’économie circulaire, de création de valeur partagée et des chaînes d’approvisionnement vertes. Deuxièmement en améliorant l’innovation technologique. Troisièmement, en construisant un système pertinent de lois et de réglementations sur la gestion des déchets de téléphonie mobile. Quatrièmement, en établissant un système d’indicateurs d’évaluation raisonnable et efficace grâce à l’utilisation de modèles mathématiques. Et enfin, en subventionnant des activités éducatives pour promouvoir la protection de l’environnement et mettre en place un ensemble de systèmes de gestion qui impliquent le public, les gouvernements et les entreprises manufacturières
Addressing the difficult problem of eliminating mobile phone waste, based on the concept of creating shared value, circular economy and green supply chain, this thesis was first demonstrated in theoretical frameworks and by the theoretical review of the literature, then put forward the idea and method to build a mobile phone waste recycling system based on these theories. To facilitate the recycling of mobile phone waste at the practical level in China and other countries, the existing problems and the way of operation are summarized, and the utilization space of mobile phone waste is expanded. Quantitative analysis is applied to examine the relevant evaluation indicators and mathematical models at the analytical level. This thesis mainly used the following four types of research methods: analytic hierarchy process,empirical analysis, quantitative and qualitative analysis, as well as an integration of the macro level and micro level analysis. Through these research methods, this thesis made a detailed analysis and discussion on the recycling status, influencing factors, the effects of use, comprehensive evaluation index system and relevant laws and regulations of mobile phone waste. After a detailed analysis, the thesis concluded that even though the evidences have showed that mobile phones waste cause serious pollution to the environment, an enormous amount of economic values still existed in the mobile phones waste. The low rates of recycling and reusing of systems could be strengthened first by improving the economic mechanism based on improving the economic mechanism based on the theories of the circular economy, creating shared value and green supply chains. Second, by improving the technological innovation. Third, by building a relevant system of laws and regulations on mobile phone waste management. Fourth, by establishing a system of reasonable and effective evaluation indicators through the use of mathematical models.

Abstract:
This is a master’s thesis project of 30 credits written with guidance from the Swedish research institute ICT Viktoria and Industrial Ecology at KTH. This thesis is conducted by two students at KTH, one with a background in Mechanical Engineering and Industrial Ecology and the other with a background in Energy and Environmental Technology. This study focuses on circular economy linked to the furniture industry in Sweden and how the transition from theoretical to practical concepts can be improved. The methods of this thesis consist of three semi-structured interviews, a survey and an analytical comparative literature review. The interviews, survey and literature review is analyzed with the purpose of finding important criteria relevant for office chairs in circular business models. The interviews are performed face-to-face with three different key persons; an office supply manager, a CEO at a refurbishing company and a product manager. The study focuses on product design within the Swedish furniture industry although some aspects regarding circular business models, logistics and psychological values are included. The results are design criteria for office chairs in circular business models and a design evaluation program for the industry built on these. The program, based on multi criteria analysis, can help reduce the gap between theory and practice of how circular economy should be implemented in the industry. By giving early feedback during the design phase on how well an office chair and a company’s structure meet circular economy criteria the authors hope to ease and speed up this transition. The main characteristics of an office chair designed for circular business models are: Durable Easy to service Adaptable Modular Homogeneous material composition in modules Although the transition to circular business models can be a comprehensive process the authors believe that if furniture manufacturers would integrate circular business models for office chairs into their business structure this would be both economically viable and highly beneficial for their environmental profile which can strengthen their position on the market.

Full text
Abstract:
Exploitative and profit-oriented business operations are unsustainably depleting the world’s resources and extensively harm the environment. Linear production systems within the manufacturing industry are partly held responsible for this ongoing issue as materials and waste are not getting reused but dumped. An alternative to the traditional linear system that increasingly gets attention in the scientific literature is a Circular Production System within the Circular Economy framework, where waste is treated as resources and streamlined back into the production system to create closed resource loops. However, most manufacturing companies nowadays follow linear production systems and have implemented the Lean philosophy to maximize output and profits, leaving environmental aspects rather behind. This context needs to be considered, when thinking of implementing circular measures within a company. Therefore, this study focused on elaborating potentials, enablers and barriers of a Circular Production System in a Lean context. A case study has been conducted within the Swedish commercial vehicle company Scania, located in Södertälje, to gather empirical data about current lean and already ongoing circular practices in a real-life environment, and on future potential of extending circular measures. Internal benchmark studies, including observational studies and semi-structured interviews have been conducted along Scania’s industrial value chain. External benchmark studies contributed to obtain data about already ongoing CPS initiatives within the manufacturing industry. Following the empirical findings, this study suggests that potentials, enablers and barriers are categorized into system, process and product level, which are interdependent and interrelated. The research revealed that due to the many influences from departments along the value chain on the production, the system as a whole needs to be investigated. This study suggests the 4R framework (reduce, reuse, remanufacture, recycle) for implementing a cascaded use of materials. Implementing a new business model giving the product ownership back to companies would facilitate circular flows in the first place. Such a new business strategy can be supported by following more advanced design strategies, that extend the product life and maintain its performance. Lean, however, was found to bear conflict issues, but is considered still useful to some extent to reduce material inputs through more efficient processes.

Abstract:
Steel industries consume refractory materials on a large scale. High temperature resistant refractory materials are essential for linings of the steelmaking vessels, to protect them from corrosive environments, high temperatures, molten steels and slags during transportation and steelmaking operations. Furthermore, with the increasing demand in steel production the usage of refractory materials has substantially increased, resulting in an increasing demand for refractory raw materials. However, with the hike in prices and abundancy for raw materials there is a need for recycling and reusing of spent refractory materials, which are otherwise sent to landfill. Nowadays the environmental as well as economic aspect regarding the recycling of spent refractories are of interest for the steel industries for achieving a solution towards zero waste. Several projects have been launched to investigate and generate new ideas with different ways to recycle refractory materials, but there is much more research and planning that needs to be done in order to find a large scale solution towards achieving zero waste. One of the simplest solutions to avoid landfilling of spent refractory is to introduce and manage a good sorting of the breakout scrap refractory, which can later be recycled or reused depending on their condition. The thesis work was carried out in collaboration of KTH – The Royal Institute of Technology/ Stockholm/ Sweden and Jernkontoret – The Swedish Steelmaking Association / Stockholm / Sweden. The work includes a collection of information regarding the current refractory waste management situation within some of the Swedish steel producers as Ovako AB, Uddeholm AB and SSAB. The information were collected on the basis of their refractory usage and practises. The thesis as well provides some suggestions for recycling and reusing of spent refractory waste materials collected from literature. Additionally some experimental work was carried out on whether an MgO-C refractory brick made of recycled materials can perform similarly against slag as a brick made from virgin materials. Experimental corrosion trials with one industrial slag composition were carried out using a hot-finger test apparatus for bricks with different amounts of recycling content in comparison to a brick made of virgin materials. After experiments, the samples were analysed using a Light Optical Microscope (LOM). A similar performance of all bricks against the slag composition was observed. Additional laboratory tests with different slag compositions, holding times and stirring rates are required to reach more profound conclusions. Industrial trials are essential with bricks containing recycled raw materials to reach a final performance status.
Stålindustrin konsumerar eldfasta material i stor skala. Högtemperatur resistenta eldfasta material är nödvändiga för att fodra skänkugnen, för att skydda den från frätande miljöer, höga temperaturer av smält stål och slagg, samt transport och blandning av smält stål under ståltillverkning. Vidare har användningen av eldfasta material ökat avsevärt med den ökande efterfrågan inom stålproduktion, vilket har resulterat i en ökande efterfrågan på eldfasta råvaror. Men i och med prishöjningen och avhållsamheten för råvaror behövs en idé om återvinning och återanvändning av eldfasta material som annars skickas till deponi. Numera är den miljömässiga och ekonomiska aspekten av återvinning av förbrukade eldfasta ämnen av intresse för stålindustrin för att kunna nå en lösning mot zero waste. Flera projekt har påbörjats för att undersöka och generera nya idéer med olika sätt att återvinna eldfasta material, men det finns mycket mer forskning och planering som behöver göras för att hitta en storskalig lösning mot netto noll avfall. En av de enklaste lösningarna för att undvika deponering av använt eldfast material är att införa och hantera en bra sortering av använt eldfast avfall, som senare kan återvinnas eller återanvändas beroende på dess tillstånd. Avhandlingsarbetet utfördes i samarbete med KTH – Kungliga tekniska högskolan / Stockholm / Sverige och Jernkontoret – Svenska stålföreningen / Stockholm / Sverige. Informationen samlades in angående användning och praxis av eldfasta material. Avhandlingen innehåller också några förslag för återvinning och återanvändning av använt eldfast avfall som samlats in från litteraturen. Dessutom utfördes experiment för huruvida en eldfast infodring av återvunnen MgO-C kan motstå reaktioner mot slagg som en infodring tillverkad av ny utvunna råvaror. Experimentella korrosionsförsök med en industriell slaggkomposition utfördes av en ugn designad för hot finger test för eldfasta material gjorda av olika mängd återvunnet material samt inget återvunnet material alls. Efter experimenten analyserades proverna med ett ljusoptiskt mikroskop (LOM). En liknande prestanda för alla tegelstenar mot slaggkompositionen observerades. Ytterligare laboratorietester med olika slaggkompositioner, hålltider och omrörningshastigheter krävs för att nå en djupare slutsats. Industriella försök är väsentliga med eldfast tegel som innehåller återvunna råvaror för att kunna nå en slutlig prestandastatus.

Abstract:
Recycling is a key component of modern waste reduction and is the third component of the “Reduce, Reuse and Recycle” waste hierarchy. Recycling and/or waste minimization is a prerequisite for sustainable value and green environment. Recyclable materials include many kinds of glass, paper, metal, plastic, textiles, and electronics. The composting or other reuse of food is also considered recycling. This chapter starts with an expanded definition of recycling; afterwards, the recycling processes of glass and aluminum are examined in detail. Besides recycling, for a green environment the necessity for reducing and reusing of waste is also considered. Another topic will be the myths of recycling-unknown realities about recycling process. Furthermore, types of recycling and cost-benefit analysis will be explained. Ultimately, the chapter will be concluded by criticisms about recycling, and potential areas for further discussion.

Abstract:
In the European Union, the potential for recycling technological and post-consumer polymeric waste is untapped. Their recycling and reuse are very low, compared to other types of waste such as glass, paper, etc., and the rates of storage, even of incineration, is very high in terms of percentage. Therefore, by reusing them, but also making use of new advanced technologies, we can contribute to improving the quality of products, and to environmental protection by recycling waste, protecting human health by eliminating toxins during their incineration, but also increasing turnover for global economic agents. Thus, this paper presents the obtaining and characterization of an antibacterial compound based on EPDM elastomer and wood waste (sawdust). The antibacterial compound is characterized from a physical-mechanical and structural point of view (FT-IR), all according to standards in force.

Abstract:
Some countries started to recycle concrete materials for reuse in structural or other issues. Some of them, like Germany, Australia and Canada have established their own recommendation guide for recycling concrete [1,2]. The recycling consists of crushing old concrete into aggregates, and then processing it into new mixture using recycled aggregates with specified sizes [3,4]. The aim of this recycling is to save nature from deforestation and dryness, by reducing the need to gravel and so the quarries work, and also to economize the waste management [5,6]. The present research work consists of an experimental study assessing the impact of using recycled aggregates on the concrete behavior and on the country’s economy. We are especially interested in determining the best composition for the new mixture of concrete resulting from reusing different types of recycled aggregates. Different types of tests have been done depending on the aggregates sizes, their origin and their state (burned or safe). The analysis is based on the comparison between compressive strength, water-cement ratio, slump, porosity and durability. Otherwise, the impact on economy is analyzed, a priori, by studying the effect of reducing the cost of the resulting concrete on construction spending. The resulted recommendations indicate the sizes of aggregates which may constitute the best composition for recycling and processing concrete, and the best use for each type of concrete depending on behavior and economy effect.

Abstract:
Abstract The recovery and reuse of printed circuit boards (PCBs) is becoming crucial in the management of electronic waste that is undergoing an exponential increase. In this study, a simple and eco-friendly process for recycling waste PCBs is discussed. In particular, composite panels were produced by reusing 100% of waste PCBs without the addition of any additive or virgin material. After a two-step grinding process, ground PCB was used to mold panels by direct molding which is pure compression molding without material sorting. Results were very promising in terms of process feasibility and part performances. Molded samples had density about 1.45 g/cm3, flexural modulus and flexural about 3 GPa and 16 MPa, respectively. A smooth surface with low friction coefficient was obtained for the recycled panels. The study shows that despite the presence of metal and other non-metal non-organic fractions, waste PCBs can be re-processed in profitable and environmentally conscious way without the addition of any bonding agent or additive. The recycling technology can be extended to the reuse of the non-metallic fraction only, after separation and recovery of metals.

Abstract:
Abstract Lithium-ion batteries (LIBs) have driven the industry of rechargeable batteries in recent years due to their advantages such as high energy and power density and relatively long lifespan. Nevertheless, the dispose of spent LIBs has harmful impacts on the environment which needs to be addressed by recycling LIBs. However, none of the currently developed recycling processes is economical. The physical recycling process of LIBs may be economical if the cathode active materials can be separated, regenerated, and reused to make new LIBs. However, the first barrier for regeneration and reusing is the separation of different types of spent cathode active materials in the filter cake that are mixed with each other and come in the form of very fine powders with various sizes (< 30 μm) from the physical recycling process. The aim of this study is to separate the mixture of cathode active materials by adopting Stokes’ law. The focus will be only on mechanical separation with no thermal or chemical separation methods. For the validation, an experiment was designed and successfully performed where different types of spent cathode materials (e.g., LiCoO2, LiFePO4, and LiMn2O4) were separated from the spent anode materials (e.g., graphite) with high efficiency and reasonable time.

Abstract:
Plastic pollution has become one of the major concerns in the world. Plastic waste is not biodegradable, which makes it difficult to manage waste plastic pollution. Recycling and reusing waste plastic is an effective way to manage plastic pollution. Because of the huge quantity of waste plastic released into the world, industries requiring a large amount of material, like the pavement industry, can reuse some of this mammoth volume of waste plastics. Similarly, the use of reclaimed asphalt pavement (RAP) has also become common practice to ensure sustainability. The use of recycled waste plastics and RAP in HMA mix can save material costs and conserve many pavement industries’ resources. To successfully modify HMA with RAP and waste plastic, the modified HMA should exhibit similar or better performance compared to conventional HMA. In this study, recycled waste plastic, linear low-density polyethylene (LLDPE), and RAP were added to conventional HMA, separately and together. The mechanical properties of conventional and modified HMA were examined and compared. The fatigue cracking resistance was measured with the IDEAL Cracking (IDEAL CT) test, and the Hamburg Wheel Tracking (HWT) test was conducted to investigate the rutting resistance of compacted HMA samples. The IDEAL CT test results showed that the cracking resistance was similar across plastic modified HMA and conventional HMA containing virgin aggregates. However, when 20% RAP aggregates were used in the HMA mix, the fatigue cracking resistance was found to be significantly lower in plastic modified HMA compared to conventional HMA. The rutting resistance from the HWT test at 20,000 passes was found to be similar in all conventional and modified HMA.
