Texte intégralRésumé :
PVC is the second most important polymer worldwide. Thanks to its excellent cost/performance ratio and outstanding chemical and environmental resistance, it is today mainly used for long-life applications. In some countries, for example, France, PVC is used in large volume for the manufacture of bottles. Pure PVC scrap can be recycled without any problems. Although many applications for such products of recycled PVC have been developed, and pilot plants for recycling exist, only small volumes have been recycled up to now. Only bottles made from PVC for the large drinking water market in France are already collected separately, recycled in large quantities, and transformed into such articles as water pipes. Specialist organisations deal with this business. In such cases, for example, kitchen waste, where PVC is part of mixed plastics waste for example, sorting and separation of the PVC is necessary.

Texte intégralRésumé :
The article presents an alternative method of recycling of dispersed metal waste, based on a continuous solid-liquid-phase process, implemented in rotary tilting furnaces (RTF). The new proposed method of recycling allows processing wastes with almost any composition and state from metal to oxide and multicomponent wastes (shavings, fine scrap, mill scale, aspiration dust, sludge, etc.). The wastes can be even contaminated with moisture, oil, and organic impurities. The method developed does not require preliminary preparation of the initial materials (cleaning, homogenization, pelletizing, etc.). The finished products are ingots (pigs) for subsequent processing aiming the particular chemical composition or cast alloys of certain brend.

Texte intégralRésumé :
Energy harvesting also known as power harvesting or energy scavenging is the process by which energy is derived from external sources solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor. Energy harvesters provide very small low-energy electronics. While the input fuel to some large-scale generation costs money (oil, coal, etc.), the energy source for energy harvesters is present as ambient background and is free. For example, temperature gradients exist from the operation of a combustion engine and in urban areas, there is a large amount of electromagnetic energy in the environment because of radio and television broadcasting

Texte intégralRésumé :
Abstract Urbanization, development of economy, increasing population and improved living standards and lifestyle have caused a sharp growth in waste. Inappropriate or inefficient waste disposal techniques can cause serious air, soil, and groundwater pollution, which subsequently can negatively affect the urban environment and threaten the health of residents. The goal of waste management is to move to a circular economy in which waste does not exist. If there is no possible way to reduce or reuse waste, the best solution is recycling it. Recycling brings abundant benefits on the economic and ecological levels levels, and helps reduce overall human health risk of adverse impacts. Recycling of the waste-cables which contain PVC and copper replaces the production of virgin PVC and mining of copper from copper ore, it reduces landfill solid waste pressures, saves energy and water sources, reduces emissions to environment, and also reduces negative impacts from improperly dispose of waste, etc. This paper presents an overview of recycling techniques for the waste-cables containing copper as a core and polyvinyl chloride as an insulating layer or sheath. It also lists advantages and disadvantages of these techniques and importance of recycling this type of waste.

Texte intégralRésumé :
The article presents an economic analysis of the state of municipal waste generation, utilization and recycling in the countries of the European Union and the Russian Federation. As a basis for the analysis, we used data on the 20 most representative countries that make a significant contribution to the formation of the main macroeconomic indicators of the EU. The results of the implementation of the EU environmental policy, the degree of reflection on the volume of trade in secondary raw materials, private investment in this sector, employment in the processing and recycling sectors, etc. are considered. In addition, a correlation analysis was carried out, which allowed us to determine the degree of dependence of waste disposal and recycling on various indicators, to identify the most significant of them and the main factor affecting the effectiveness of the country’s environmental policy.

Phd thesis, Université Toulouse le Mirail - Toulouse II, 2012. http://tel.archives-ouvertes.fr/tel-00711199.
Texte intégralRésumé :
Le contexte de la gestion des déchets est soumis à des orientations politiques changeantes qui se font l'écho, d'une part de la volonté de préserver les ressources, d'autre part, de l'avènement de l'écologie industrielle. Pour aborder ces enjeux, cette recherche, conduite à l'interface entre sciences de l'ingénieur, sciences sociales et sciences du territoire, s'intéresse plus précisément aux dimensions technico-économiques, sociopolitiques et spatiales des filières de récupération-recyclage. Elle aborde la manière avec laquelle est favorisé le développement territorial de ces filières, en se focalisant particulièrement sur la filière des déchets d'équipements électriques et électroniques (DEEE). Elle s'interroge sur la contribution du système local de recyclage au développement des démarches d'écologie industrielle. Elle s'appuie notamment sur l'analyse systémique de la mise en oeuvre de l'opération de récupération-recyclage des DEEE en Midi-Pyrénées.Cette recherche montre comment l'objet DEEE met à l'épreuve la territorialisation de la réglementation européenne et française de la gestion des déchets. Basée au départ sur une étude quantitative des flux de matières et d'énergie de la filière, la question se déplace progressivement vers l'étude qualitative des divers positionnements du système d'acteurs qui pilotent le métabolisme de la filière.

Margaret Popoola, Bukola. « Biodegradable Waste ». Dans Recycling - Recent Advances [Working Title]. IntechOpen, 2022. http://dx.doi.org/10.5772/intechopen.107910.
Texte intégralRésumé :
Biodegradable wastes are waste materials easily degraded or broken down naturally by factors such as biotic (bacteria, fungi, plants, animals, etc.) and abiotic (pH, temperature, oxygen, humidity, etc.). This process enables complex substances to be broken down into simpler organic compounds which subsequently fade into the soil. This is a natural process that could be prolonged or rapid and poses little risks to the environment. These waste materials could be termed green waste; including food waste, paper waste, and biodegradable plastics such are found in municipal solid waste. Other examples of biodegradable wastes include sewage, manure, sewage sludge, human waste, waste from various slaughterhouses, hospital waste, dead animals, and plants. Biodegradable waste could be said to be recyclable or reused; furthermore, bio-waste recycling may also directly contribute to climate protection. They are generally known as useful waste. Recycling is one of the current waste management strategies having great benefits for the environment.

Dans Advances in Transdisciplinary Engineering. IOS Press, 2021. http://dx.doi.org/10.3233/atde210122.
Texte intégralRésumé :
The use of carbon fiber reinforced polymers (CFRPs) has expanded in many industries due to superior properties compared to traditional materials. Nevertheless, their recycling is challenged by immature recycling market and poor legislative support. This study evaluates the application and disposal of CFRPs within the different industries in Kazakhstan. The study adopted a market-based analysis approach to understand the up-to-date levels of application of CFRPs across manufacturing, construction, aviation, and other relevant industries of Kazakhstan. The study also considered CFRP markets and associated recycling practices in neighboring countries such as China and Russia which have a significant impact on Kazakhstan in terms of import and export of materials and waste. The research findings indicate that the application of CFRPs varies among industries, construction being the most prominent, however, their recycling is not as organized as in other waste types such as plastic, metals, etc. Russia and China will be generating thousands of tonnes of CFRP waste originating from the wind turbine and aviation sectors in future, from which Kazakhstan may also see some benefits. The findings of the study are deemed to be useful for the government of Kazakhstan and waste recycling associated stakeholders for future considerations.

Texte intégralRésumé :
The immense utilization of plastics has produced an enormous amount of plastic waste. So, basically there is a necessity created for proper method for plastic waste management. As, we know plastics is the most essential part of our life and used in every application and has a very versatile portfolio used everywhere from industries to households. We can say that the use of plastics is inevitable. In the present time adoption of sustainability principles including selection of the best recycling process is important for optimum utilization of the resources. As there are various plastic waste management strategies available, their prioritization on the basis of several criteria like health, safety, the environment impact, etc. is relevant for the stakeholders involved in this sector . Main objective as to apply by using different criteria as multi- criteria decision making to conduct an analysis which are based on a hierarchical structure that is multi-level and analysis of plastic waste management methods. The AHP approach is a (MCDM) tool which we adopt in our study to depict the best suitable method for the Plastic Waste Management for the industries. As the identification of criteria for the plastic recycling process based on the literature review and expert discussions was done for this the study was initiated. Further, the weightage of different criteria and ranking of the available methods were done using AHP. Four commonly used plastic waste management alternatives were evaluated and findings reveal that recycling is the best alternative. This study will help the industries in selection of best possible techniques and methods for plastic waste management. By this deep study we will be able to find out the best method which can be used for plastic waste management and AHP approach gives us a clarity and it takes various attributes to reach out to a result. This technique is inter-related to Operation Research subject. From this paper we can conclude that out of Incineration, landfilling, Mechanical Recycling and Road filling , Mechanical Recycling comes out to be the best method that can be used for Plastic Waste Management and it should be mainly utilized further.

Texte intégralRésumé :
Under environmentally friendly and environmental issues, wastewater treatment in laboratories and factories is an important international issue. Among them, wastewater from the chemical industry accounts for a large part of industrial wastewater discharge. The introduction of new technologies to treat chemical wastewater is of great significance. In particular, the amount of wastewater produced by inorganic chemistry experiments is relatively large, and the pollutants are mostly heavy metal salts. According to the characteristics of inorganic chemistry experimental wastewater, such as special nature, small amount, strong discontinuity, high hazard, complex and changeable composition, etc., design a chemical reaction to provide a practical and feasible method to treat wastewater with high efficiency and low cost. This research initially takes Ni+ metal ion waste liquid as the first stage of recycling and treatment to improve the traditional low-concentration non-economic treatment. The preliminary results of this research are neutralization reaction and optimal pH value control of Ni+ waste liquid to generate Ni+ precursors to increase the economic value of recycling will be the basis for providing in-house recycling systems for electroplating plants, panel plants, and semiconductor plants to achieve emission reduction, green chemical industry and green environmental protection.

Texte intégralRésumé :
Production-operation activity is one of the most important functions of modern enterprises. It requires the involvement of various types of resources, such as: raw materials, materials, machines, capital, information, energy, human factor and others, which are used in production processes. However, many problems arise in operational activity. They concern such aspects as: waste of resources or their wasteful use, mismanagement, excessive energy consumption, environmental pollution, exploitation of human potential, etc. It is also emphasized that these problems are reflected both in the growing costs of a company’s activities and in climate change. However, more and more companies are becoming aware of these dangers and are implementing new products, new technologies and processes that use less raw materials and energy, being more environmentally-friendly. The purpose of implementing new solutions of production is to improve labour mobility, optimise the use of raw materials and resources, reduce costs, and to increase efficiency, productivity, etc. Taking the impact of operating activities on the environment into account, the purpose of this chapter is to present selected production methods from their cognitive aspects, the assumptions of which are consistent with the issues of sustainable development. In particular, focus was placed on the zero-waste concept, which allows to eliminate waste in all links of the value chain. Lean manufacturing and six sigma, which help enterprises fight waste in their activity, as well as circular production related to the implementation of closed-loop production principles in practice, are discussed. In addition, the life-cycle product design and recycling, as well as green and environment-conscious manufacturing are presented. The first of them assumes that the possibility of recycling should be considered in the process of designing products and services. The second one should be identified with a modern and systemic way of managing enterprises, taking all environmental aspects into account by all departments.

Fontana, Gianfranco. « The Orange Peel : An Outstanding Source of Chemical Resources ». Dans Citrus - Research, Development and Biotechnology. IntechOpen, 2021. http://dx.doi.org/10.5772/intechopen.96298.
Texte intégralRésumé :
Citrus sinensis (L.) Osbeck is a very common cultivar belonging to the Rutaceae family. It is largely diffused in several areas of the world characterized by mild to warm climate conditions. Its abundant worldwide production (up to 107 Tons. per year) and consumption both as the edible part of the fruit and as several types of derivative products imply the production of a huge amount of waste, such as the fruit pomace. Several ways of recycling this material have been developed in recent years: employment as fertilizer, fodder ingredient, and even cloth material. However, the chemical added value of Citrus sinensis peel has been underestimated despite the diversified and significant content of useful chemicals, such as polyphenols, polymethoxylated phenols, glycosylated flavonoids, volatile and non-volatile terpenoids, pectins, enzymes, etc. This work aims to highlight the outstanding chemical potential of Citrus sinensis peel.

Texte intégralRésumé :
The problem of landfills is one of the most important and urgent among the problems of environmental pollution. This issue needs an immediate solution not only in Ukraine but all over the world. Every human home accumulates a huge amount of unnecessary materials and products, from old newspapers and magazines, empty cans, bottles, food waste, wrappers and packaging, to broken dishes, worn clothes and broken appliances or office equipment. Every day we are forced to deal with waste: at home, in the environment). Everywhere we are surrounded by papers, plastic wrappers, glass, cellophane, etc. Today, taking into account the environmental factor is a necessary condition for the integration of the Ukrainian economy into world economic processes in order to ensure its competitiveness. Ukrainian enterprises face an important issue of the need to understand environmental prioritiesin the implementation of production and economic activities. That is why the introduction of new technologies, improving environmental culture, compliance with generally accepted environmental standards, the search for effective tools for environmental and economic management of enterprises, territories and regions is a necessary component of future sustainable development. In turn, the practical implementation of the principles of environmentally sustainable development of economic, socio-economic systems necessitates the improvement of methods, methods and tools of production organization based on the greening of the logistics management system. It has become clear that the economy needs to be reorganized so that human industrial activity is fully integrated into an efficient environmental infrastructure. Thus, the study of the process of transport waste management in Ukraine and the world is relevant today. Transport infrastructure includes railways, trams and inland waterways, contact lines, highways, tunnels, overpasses, bridges, railway stations, railway and bus stations, subways, airfields and airports, communication, navigation and traffic management facilities. vehicles, as well as other structures, devices and equipment. Vehicles include aircraft, railway rolling stock, vessels used for the purpose of merchant shipping or shipping, rolling stock of road and electric urban land passenger transport. The subject of the research is the ability of microorganisms isolated from the landfills of the transport infrastructure of Kyiv to biodegrade fuel and lubricants. Research methods: monographic, analytical methods, standard microbiological and research of physicochemical and operational properties of kerosene and diesel fuel. The purpose of research: to investigate the ability of microorganisms isolated from the landfill of the transport infrastructure of Kyiv to the destruction / degradation of fuels. Further use of isolated microorganisms in biodegradation technologies of waste fuels and oils. Achieved results: the ability of a complex of micro-organisms isolated from the landfill of transport infrastructure of Kyiv to the destruction / degradation of fuels was studied; developed an algorithm and method for isolating a complex and pure cultures of microorganisms capable of destruction / degradation of hydrocarbons of petroleum products (diesel fuel, kerosene); developed a method of utilization of waste fuels and lubricants and solid organic (food) waste using isolated from samples taken at landfills of transport infrastructure.

Texte intégralRésumé :
The fundamental aim of this research is to inform the reader about the importance of implementing sustainable practices at a business and social level, focusing on reducing the impact of cigarettes on the environment. After going through all the data, the idea is to make the readers think critically about why and how they can contribute to reducing cigarette littering and the consequent pollution. The research contains the analysis on different proposals, if they can be applied, and how to educate society to decrease cigarette waste. This study represents a review of the literature documenting the impact of cigarettes´ chemicals on the environment, and how consumers behave (if recycling or throwing cigarettes away). The expected research results would be encountering a wide range of alternatives and feasible solutions to replace the actual composition of conventional cigarettes, and strategies to educate the smokers´ population about the importance of reutilizing the leftovers from cigarettes. In this way, changing actual practices and reducing pollution would contribute to a more sustainable world, from which all, businesses and consumers, would benefit. I chose this topic because I consider it as a latent issue in many countries, and I strongly believe that educating about this problem can protect people who are exposed to these chemicals in their daily life, either if they consume tobacco products or if they drink contaminated water, deal with smoke-filled air, etc. Protecting natural life is also crucial, as polluted oceans influence greatly not only our present but also our future as humankind.

Texte intégralRésumé :
Climate change, resource depletion, technical progress, growing consumer awareness and changing requirements causes companies to look for new production methods. They may concern various areas of the company’s activity, starting from product design, procurement organization, optimization of production processes, control of manufactured products and services, through improvement of work organization and reduction of production costs, and ending with the implementation of modern solutions based on digital technologies. The purpose of implementing new production methods is to improve labour mobility, optimization of the use of raw materials and resources, costs reduction, increase efficiency, productivity, etc. In the literature, there are many different types of methods that can be used by modern enterprises. It is practically impossible to present all methods in this study. The authors focused on the presentation of selected methods, which are characterized on the one hand by innovation and, on the other hand, by the possibility of implementation. Particular attention should be paid to methods focused on environmental aspects. This group presents basic information on environment-conscious manufacturing (ECM), life-cycle assessment (LCA) and waste management and recycling. These methods allow to implement the concept of sustainable development and are directly related to the 17 goals set out in the 2030 Agenda for Sustainable Development and adopted by UN member states. In the group of methods related to next generation production management, the focus was on Matrix shop floor control and cooperative manufacturing. Of particular importance is cooperative management, because cooperation in practice is considered as a specific resource and one of the most important factors of a competitive position. The next group of methods concerned production planning and control. Drum Buffer Rope (DBR) and theory of constraints (TOC) were discussed as part of it. From the company’s point of view, methods related to manufacturing processes are very important, including group technology (GT) and cellular manufacturing (CM). Another group focused on commercial aspects, including demand chain management (DCM) and competitive intelligence (CI). The chapter also presents methods related to auxiliary software support, advanced organizational manufacturing and focused on product design. In the first case, Electronic Data Interchange (EDI) was discussed, in the second, virtual enterprises (VE) and World Class Manufacturing (WCM) were presented, and in the third, the assumptions concerning the Quality Function Deployment (QFD) and House of Quality (HOQ) method were shown. Additionally, Statistical Process Control (SPC) and Computer-Aided Process Planning (CAPP) are discussed within the framework of methods focused on cost and quality manufacturing.

Texte intégralRésumé :
In the last ten years, public and government perceptions of waste-to-energy have changed considerably. Most people who bothered to visit waste management facilities recognize that landfilling can only be replaced by a combination of recycling and thermal treatment with energy recovery. During the same period, the Earth Engineering Center (EEC) of Columbia University research and public information programs have concentrated on advancing all means of sustainable waste management in the U.S. and abroad. The results of EEC research are exemplified in the graphs of the Hierarchy of Waste Management and the Ladder of Sustainable Waste Management of nations; in this paper, the latter has also been used to compare the waste management status of the fifty states of the Union. This paper also describes how the European Union has directed that thermally efficient treatment of MSW is equivalent to recycling. The rapid growth of WTE in this century is exemplified by the hundreds of new WTE plants that have been built or are under construction, most with, government assistance as in the case of other essential infrastucture. The need for concerted action by concerned scientists and engineers around the world has led to the formation of the Global WTERT Council. By now there are sister organizations of EEC and WTERT in Brazil, Canada, China, France, Germany, Greece (SYNERGIA) and Japan. Others are being formed in other countries.

Texte intégralRésumé :
The management of the large quantities of very low level radioactive material that arise during the decommissioning of the increasing numbers of nuclear power stations reaching the end of their commercially useful lives, has become a major subject of discussion. This has very significant economic implications for the nuclear decommissioner. Much larger quantities — 2–3 orders of magnitude larger — of material, radiologically similar to the candidate material for recycling from the nuclear industry, arise in non-nuclear industries like coal, fertiliser, oil and gas, mining, etc. In such industries, naturally occurring radioactivity is artificially concentrated in products, by-products or waste to form TENORM (Technologically Enhanced Naturally Occurring Radioactive Material). It is only in the last decade that the international community has become aware of the prevalence of TENORM, specially the activity levels and quantities arising in so many non-nuclear industries. The first reaction of international organisations seems to have been to propose different standards for the nuclear and non-nuclear industries, with very stringent release criteria for radioactive material from the regulated nuclear industry and up to thirty to a hundred times more liberal criteria for the release/exemption of TENORM from the as yet unregulated non-nuclear industries. The radiological effects of these TENORM releases have recently been dramatically highlighted by the Marina II study, which showed that over 90% of the total exposures of the European population from discharges into the North European marine waters are from radioactive discharges from non-nuclear industries. The results of an international project to validate, by actual measurement, dose calculation codes RESRAD-RECYCLE (USA) and CERISE (France) for recycling, have indicated an overestimation of doses by the codes by an order of magnitude. For the nuclear decommissioner and other producers of large volumes of slightly radioactively contaminated material, clearance levels determined on the basis of such a degree of conservatism in calculations can lead to huge volumes of material unnecessarily being condemned to burial as radioactive waste. Earlier estimates of the quantitative risk levels of exposure to ionising radiation have almost exclusively been based on doses taken by exposed populations of Hiroshima and Nagasaki (ICRP 60). The populations studied have been exposed to over 200 mSv at a dose rate of 6 Sv/s. The effects of such high dose/dose-rate exposure are being used as the basis for risk judgment at doses/dose-rates lower by a factor 1012–1015. The validity of such an extrapolation in risk judgement is an area of prime interest for discussion. In this connection, an interesting development, for both the nuclear and non-nuclear industries, is the increased scientific scrutiny that the populations of naturally high background dose level areas of the world are being subject to. Preliminary biological studies have indicated that the inhabitants of such areas, exposed to many times the permitted occupational doses for nuclear workers, have not shown any differences in cancer mortality, life expectancy, chromosome aberrations or immune function, in comparison with those living in normal background areas. The paper discusses these and other strategic issues regarding the management of redundant low radiation material from both the nuclear and non-nuclear industries, underlining the need for consistency in regulatory treatment.

Dans ASME 2012 11th Biennial Conference on Engineering Systems Design and Analysis. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/esda2012-82106.
Texte intégralRésumé :
In order to decrease both energy consumption and CO2 emissions, the automotive, aeronautics and aerospace industries aim at making lighter vehicles. To achieve this, composite materials provide good opportunities, ensuring high material properties and free definition of geometry. As an example, for cold applications, the use of carbon fiber/thermoset composites is ever increasing, in spite of a high fiber price. But in a global and eco-friendly approach, the major limitation for their use remains their potential recyclability. Recycling a composite means having a recycling technology available, getting a dismantle solution and an access for the product, and disposing identification plus selection possibilities to the materials. Thus, carbon fibers recovery (i.e. recycling and re-processing) would both help design engineers to balance energy efficiency and cost, and open new opportunities for developing second-life composites, dedicated to the manufacture of medium or low loaded parts (non-structural in many cases). A first section presents an overview of composite recycling possibilities. Indeed, environmentally and economically, composite incineration is not attractive (even with an energetic valorization), let-alone burying. Reuse and recycling thus remain the two most interesting options. Aeronautics offers a high potential in terms of fiber deposit. In southwest France, composites recycling will increase in terms of quantity due to dismantling platforms Tarmac (dedicated to civil aircraft applications) and P2P (for the disassembly of ballistic weapons). In addition, from a technical point of view, and even if end-of-life solutions for composites still remain under development, solvolysis (i.e. water under supercritical conditions) already offers the opportunity to recover carbon fibers. The resulting recyclate retains up to 90 percent of the fiber’s mechanical properties. A second part will explore the recycling to design issue (i.e. how recycling processes have to balance the previous aspects of the end-of-life proposal). The recycler clearly becomes a new supplier in the carbon fiber lifecycle, by revalorizing wastes with alternatives to burning. Moreover, increasing carbon fiber shelf life reduces its product life impact. Finally, promoting carbon fiber end-of-life would ensure to link aeronautics, automotive, and leisure and sports industries; but one can create demand for recycled reinforcement, by packaging it in useful and attractive forms for those end-users (e.g. pseudo-continuous fiber, felt, strips, bands, patches, etc.). These sections will be enlightened by several examples from collaborations between I2M and local industries.

Dans ASME 2010 13th International Conference on Environmental Remediation and Radioactive Waste Management. ASMEDC, 2010. http://dx.doi.org/10.1115/icem2010-40081.
Texte intégralRésumé :
France’s experience in the management of radioactive waste is supported by forty years of operational activities in the field of surface disposal. This feedback is related to three disposal facilities: Centre de la Manche disposal, not far away Cherbourg, from design to post-closure facility. Centre at Soulaines-Dhuys from site selection to design to operation during nearly 20 years. Centre at Morvilliers from site selection to operation for seven years now. During the operational period of Centre de la Manche disposal facility (1969–1994), the safety concept for low- and intermediate level short lived waste (LIL-SLW) was developed and progressively incorporated in the procedures of the facility. The facility entered its institutional control period and the experience of this facility has been useful for the operating facilities. Centre de l’Aube that took over Centre de la Manche, and Morvilliers for very low level wastes. Both facilities currently accommodate the major part of the volume of radioactive wastes that are generated in France. However disposal facilities have to be considered as rare resources. Then new waste management options are being investigated as the disposal of large components or recycling metallic wastes within the nuclear industry.

Dans ASME 2016 International Design Engineering Technical Conferences and Computers and Information in Engineering Conference. American Society of Mechanical Engineers, 2016. http://dx.doi.org/10.1115/detc2016-59842.
Texte intégralRésumé :
Municipal solid waste (MSW), generated at an unprecedented rate due to rapid urbanization and industrialization contains useful recyclable materials like metals, plastic, wood, etc. Recycling of useful materials from MSW in the developing countries is severely constrained by limited door-to-door collection and poor means of segregation. Recovery of recyclables is usually performed by waste pickers, which is highly risky and hazardous for their health. This paper reports the development of a robotic mobile manipulation system for automated sorting of useful recyclables from MSW. The developed robot is equipped with a thermal imaging camera, proximity sensor and a 5-DOF robotic arm. This paper presents an approach for sorting based on automated identification from thermographic images. The developed algorithm extracts keypoint features from the thermographic image and feeds into clustering model to map them into a bag-of-word vectors. Finally, Support Vector Machine (SVM) classifier is used for identifying the recyclable material. We used the developed algorithm to detect three categories of recyclables namely, aluminum can, plastic bottle and tetra pack from given thermographic images. We obtained classification rate of 94.3% in the tests. In future, we plan to extend the developed approach for classifying a wider range of recyclable objects as well as to incorporate motion planning algorithms to handle cluttered environments.

Texte intégralRésumé :
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.

Texte intégralRésumé :
Air-Cooled Condenser performance can significantly affect WTE plants bottom-line. Most of the possible ACC performance improvement solutions require some important capital costs (fin tubes replacement, fans blades or motor upgrade, additional ACC cells, addition of preventive air re-circulation panels, etc…). A new low cost tool and methodology is now allowing to gain a very detailed understanding of ACC behaviours and to optimize ACC operations and cleaning schedules. This article is illustrated by the case-study of a WTE located in the south of France (equipped with a 5.5 MW GE condensing turbine), where the facility performance was strongly limited by its ACC, and where additional turbine generator output of more than 1 MW were achieved.

Texte intégralRésumé :
Siempelkamp Nukleartechnik GmbH has gained lots of experience from melting ferrous metals for recycling in the nuclear cycle as well as for release to general reuse. Due to the fact that the world market prices for non-ferrous metals like copper, aluminium or lead raised up in the past and will remain on a high level, recycling of low-level contaminated or activated metallic residues from nuclear decommissioning becomes more important. Based on the established technology for melting of ferrous metals in a medium frequency induction furnace, different melt treatment procedures for each kind of non-ferrous metals were developed and successfully commercially converted. Beside different procedures also different melting techniques such as crucibles, gas burners, ladles etc. are used. Approximately 340 Mg of aluminium, a large part of it with a uranium contamination, have been molten successfully and have met the release criteria of the German Radiation Protection Ordinance. The experience in copper and brass melting is based on a total mass of 200 Mg. Lead melting in a special ladle by using a gas heater results in a total of 420 Mg which could be released. The main goal of melting of non-ferrous metals is release for industrial reuse after treatment. Especially for lead, a cooperation with a German lead manufacturer also for recycling of non releasable lead is being planned.

Texte intégralRésumé :
In the 1990–2010s in the region, measures were taken to increase the volume of waste processing of large industrial enterprises. However, the following problems remained unresolved: lack of funding, outdated recycling technologies, lack of attention from regional and federal authorities. There were also positive steps. In particular, the disposal of hazardous waste was started at enterprises where this has not happened for a long time (according to Usolekhimprom, Baikal Pulp and Paper Mill, Angarsk Metallurgical Plant, etc.). Huge volumes of ash and slag materials and waste from the timber processing industry were used.

Dans The 8th International Conference on Advanced Materials and Systems. INCDTP - Leather and Footwear Research Institute (ICPI), Bucharest, Romania, 2020. http://dx.doi.org/10.24264/icams-2020.iv.13.
Texte intégralRésumé :
Elastomeric and plastic materials are used in different sectors of the European Union, and their recycling and reuse is still at a low level, compared to other types of waste (paper, glass, etc.). By approaching an efficient global strategy related to waste management, it is possible to make the transition to a circular economy with low CO2 emissions, offering the population a cleaner and safer environment. Due to the transformation of waste by various methods into new value-added products, we can say that their life cycle contributes to the efficiency of the economy and to the reduction of the negative impact on the environment. Research can make a difference in preventing the generation of technological and post-consumer polymeric waste by making biodegradable polymer composites that are harmless to the environment and ecosystem. The biodegradable polymer composites based on EPDM elastomer and rubber waste (rubber powder) were made on equipment specific to elastomers and characterized rheologically and physically-mechanically according to the standards in force.

Texte intégralRésumé :
We believe the climate crisis will be resolved in cities. Today, while cities occupy only 2% of the Earth's surface, 57% of the world's population lives in cities, and by 2050, it will jump to 68% (UN, 2018). Currently, cities consume over 75% of natural resources, accumulate 50% of the global waste and emit up to 80% of greenhouse gases (Ellen MacArthur Foundation, 2017). Cities generate 70% of the global gross domestic product and are significant drivers of economic growth (UN-Habitat III, 2016). At the same time, cities sit on the frontline of natural disasters such as floods, storms and droughts (De Sherbinin et al., 2007; Major et al., 2011; Rockström et al., 2021). One of the sustainability pathways to reduce the environmental consequences of the current extract-make-dispose model (or the "linear economy") is a circular economy (CE) model. A CE is defined as "an economic system that is based on business models which replace the 'end-of-life' concept with reducing, alternatively reusing, recycling and recovering materials in production/distribution and consumption processes" (Kirchherr et al., 2017, p. 224). By redesigning production processes and thereby extending the lifespan of goods and materials, researchers suggest that CE approaches reduce waste and increase employment and resource security while sustaining business competitiveness (Korhonen et al., 2018; Niskanen et al., 2020; Stahel, 2012; Winans et al., 2017). Organizations such as the Ellen MacArthur Foundation and Circle Economy help steer businesses toward CE strategies. The CE is also a political priority in countries and municipalities globally. For instance, the CE Action Plan, launched by the European Commission in 2015 and reconfirmed in 2020, is a central pillar of the European Green Deal (European Commission, 2015, 2020). Additionally, more governments are implementing national CE strategies in China (Ellen MacArthur Foundation, 2018), Colombia (Government of the Republic of Colombia, 2019), Finland (Sitra, 2016), Sweden (Government Offices of Sweden, 2020) and the US (Metabolic, 2018, 2019), to name a few. Meanwhile, more cities worldwide are adopting CE models to achieve more resource-efficient urban management systems, thereby advancing their environmental ambitions (Petit-Boix & Leipold, 2018; Turcu & Gillie, 2020; Vanhuyse, Haddaway, et al., 2021). Cities with CE ambitions include, Amsterdam, Barcelona, Paris, Toronto, Peterborough (England) and Umeå (Sweden) (OECD, 2020a). In Europe, over 60 cities signed the European Circular Cities Declaration (2020) to harmonize the transition towards a CE in the region. In this policy brief, we provide insights into common challenges local governments face in implementing their CE plans and suggest recommendations for overcoming these. It aims to answer the question: How can the CE agenda be governed in cities? It is based on the results of the Urban Circularity Assessment Framework (UCAF) project, building on findings from 25 interviews, focus group discussions and workshops held with different stakeholder groups in Umeå, as well as research on Stockholm's urban circularity potential, including findings from 11 expert interviews (Rezaie, 2021). Our findings were complemented by the Circular Economy Lab project (Rezaie et al., 2022) and experiences from working with municipal governments in Sweden, Belgium, France and the UK, on CE and environmental and social sustainability.

Texte intégralRésumé :
Despite growing interest and recognition of urban and peri-urban agriculture (UPA) as a nature- based solution, there is limited empirical evidence in countries like India on its role in reconfiguring goals on environmental functions (such as biodiversity, waste management, water recycling, micro-climate regulation, etc.) and social wellbeing (such as food and nutrition security, gender relations, work burdens, land tenure and community ties). A need to address this gap led to the ideation of the project ‘Urban and peri-urban agriculture as green infrastructures’ ( UPAGrI ). When UPAGrI started in 2019, the research on UPA in India was thin but growing. However, the practical experience of urban farming across Indian cities is thriving and diverse, built on decades of bottom-up experimentation. Within the landscape of our ever-changing cities, we found vibrant communities-of-practice sharing seeds and knowledge, engaged online influencers discussing composting and water reuse, and stories of farming becoming sites of multi-generational bonding and nutritional security. This compendium is a collection of 29 such innovative UPA practices from across the different cities in the country. These diverse case studies are loosely categorized into four themes: environment and sustainability; food, nutrition and livelihood; gender and subjective well-being; and urban policy and planning. Written mostly by practitioners themselves, the case studies collectively recognise and celebrate UPA innovations and practices, serving as a repository of lessons for peer-to-peer learning, and demonstrating how UPA can be one of the many solutions towards sustainable, liveable Indian cities.
