The purpose of this thesis to increase the understanding of how Extended Producer Responsibility (EPR) affects the economy. EPR is a principle stating that producers should be responsible for the environmental impact of their products throughout the life cycle. In four out of five essays, scrapping of end-of-life vehicles in Sweden is used as an example. In Essay I the interdependency of the consumers’ and the producers’ responsibilities are stressed. It is concluded that the financial solution should be separated from the producer in order to ensure that future liabilities can be met. The main contribution of Essay II is that an increased premium will result in an increased number of returned vehicles. In Essay III it is shown that when the environmental harm is constant and relatively low, a deposit-refund system is preferred to an unfounded system. In cases where high environmental harm occurs the optimal choice would be a system combining both deposits and fines. Essay IV concludes that a funded system would have been a better way to finance the premium than an unfunded system in terms of higher rate of return. In Essay V the analysis is no longer limited to ELVs, and a model with endogenous growth is applied to the case where all the products in the economy are covered by EPR. It is found that both the growth and the level of output is favoured by the choice of a funded scheme. / Syftet med avhandlingen är att studera hur ekonomin påverkas av utökat producentansvar. Utökat producentansvar är ett sätt att internalisera miljökostnader i marknadspriset. Producentansvaret för bilar, så som det implementerats i den svenska lagstiftningen, har lagts till den tidigare lagstiftningen utan några större anpassningar. Effekterna av detta har inte tidigare utretts. Först analyseras dess konsekvenser i en översiktlig artikel. Därefter följer en ekonometrisk artikel vars syfte är att testa effekten av den nuvarande bilskrotningspremien. Det visade sig att en höjd premie ökar antalet återlämnade fordon. Sedan används en rättsekonomisk ansats för att förutsättningslöst, dvs. utan att ta den befintliga lagstiftning som utgångspunkt, analysera nedskräpningsproblematiken. Möjligheten att använda ett pantsystem jämförs med att använda böter för att styra individernas beteende. Det visade sig att om miljöpåverkan är relativt liten så är ett pantsystem att föredra, men om även fall med stor miljöpåverkan inkluderas skulle det optimala vara att använda både böter och pant. Därefter jämförs två alternativa sätt att finansiera premien, ett fonderat system jämförs med ett ”Pay-As–You-Go” system. Resultatet indikerar att ett fonderat system hade varit att föredra under den studerade perioden. Slutligen studeras effekterna av producenternas framtida åtaganden till följd av det utökade producentansvaret med hjälp av modell med endogen tillväxt. Det visade sig att både tillväxttakten och nivån på produktionen skulle ha gynnats av ett fonderat system.

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE” requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled. This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden. Magnetic fines is a complex material containing e.g. ferrous metals, non-ferrous metals, glass, plastic, rubber, polyurethane, sand, dirt, brominated flame retardants and PCB. Characterisation of the material and discussion around area of application resulted in suggestions for possible recycling alternatives. Characterisation included e.g. particle size, total organic content, x-ray fluorescence, x-ray powder diffraction and elemental analysis with a focus on the metals. The results indicated a higher organic content in larger particles and an increasing content of e.g. lead, cadmium and mercury in smaller particles. X-ray fluorescence can be used to measure lead in magnetic fines. The conclusion was that the combustible organic content needs to be separated before further metal recycling can be applied. If magnetic fines should be used in construction pollutants probably either needs to be removed or encapsulated to prevent exposure to humans and environment.

Recycling and recovery of materials and energy from waste is a key factor to mitigate virgin material demands and reduce resource consumption by utilising waste as a resource for new products. However, some critical materials, such as neodymium, are barely recycled because of missing information on amount and disposition of these critical materials within the waste streams. The goal of the study is to quantify recycling potentials from small and electric motors originating from end-of-life vehicles (ELV), electric bicycles and industrial machinery in Germany and the EU with focus on currently lost rare earth elements. Furthermore, innovative approaches to improve recycling of these motors shall be investigated. Therefore, a calculation model to predict current and future waste streams and the incorporated recycling potentials has been developed. The results show an increasing trend of recycling potentials from small and electric motors for all waste streams. The recycling potential of neodymium is estimated at a range of 150 t to 240 t in 2020 in Germany. However, data inaccuracy and the calculation model are likely to cause overestimation of actually available recycling potential and have to be interpreted carefully. In conclusion, disassembly of small and electric motors from ELV and electric bicycles in combination with a subsequent specific recycling process has been identified as promising to improve utilisation of the recycling potentials of rare earth elements from small and electric motors. However, in case recycling quotas are the prior goal of improvement, the application and further optimisation of post shredder technology is more relevant.

A escassez de sistemas consolidados de reciclagem de veículos no Brasil e o grande volume de veículos em final de vida (VFVs) junto aos pátios do Departamento Estadual de Trânsito do Rio Grande do Sul - DETRAN/RS serviram de base para o desenvolvimento desta dissertação. Em face disso, o objetivo deste trabalho foi desenvolver um sistema de reciclagem de VFVs ambientalmente mais sustentável, a partir de exemplos globais de melhores práticas adotadas, atendendo à legislação vigente do país. Para tanto, a presente dissertação é composta por dois estudos fundamentados em revisões sistemáticas e em estudos de caso. Inicialmente, como resultado da primeira revisão sistemática, foi realizada a comparação de sistemas de gestão de reciclagem de veículos, identificados em 25 países. Essa comparação possibilitou ampliar o conhecimento de tecnologias e de procedimentos adotados em diferentes realidades, permitindo a proposição de oito políticas a serem adotadas em âmbito nacional, bem como três ações de melhoria ao atual sistema do DETRAN/RS. Em seguida, a segunda revisão sistemática permitiu a proposição de um sistema ambientalmente adequado para reciclagem de VFVs, que sirva de base para a futura padronização de processos de reciclagem, visando a potencial criação de centros especializados em reciclagem de veículos (CERVs). Diante do exposto, os resultados da pesquisa demonstraram que o tema da reciclagem de veículos está inserido num cenário mais amplo, necessitando da participação de todos os stakeholders envolvidos no processo, a exemplo: (i) das montadoras e fabricantes de peças, no desenvolvimento de tecnologias automotivas; (ii) dos entes federados, na criação de legislações mais rígidas e específicas, com foco na economia circular; e (iii) da sociedade na busca de produtos eco-amigáveis. Por fim, conclui-se que, associado às políticas e ações de melhoria sugeridas, a adoção do sistema ambientalmente adequado para reciclagem de VFVs proposto, poderá acelerar a criação de um ambiente favorável para o desenvolvimento e a consolidação da reciclagem no país. / The scarcity of consolidated vehicle recycling systems in Brazil and the huge amounts of endof- life vehicles (ELVs) at the Transit State Department of Rio Grande do Sul - DETRAN/RS courtyards served as the basis for the development of this Masters dissertation. Therefore, the objective of the work was to develop an environmentally more sustainable ELVs recycling system, based on global adopted best practices, without disregarding the country's current legislation. So, this dissertation is composed of two studies based on systematic reviews and on case studies. Initially, as a result of the first systematic review, a comparison of vehicle recycling management systems was carried out, identified in 25 countries. This comparison allowed the increasing of the knowledge about technologies and procedures adopted in different realities, making possible a proposal of educational policies to be adopted at national level, as well as three improvement actions for the current system of the DETRAN/RS. Subsequently, a second systematic review allowed a proposal for a suitable environmentally recycling system for the ELVs, which serves as the basis for a standardization of recycling processes, aiming the potential creation of specialized centers for such processes (CERVs). Considering this, the research results showed that the theme of product recycling is inserted in a broader scenario, requiring participation of all stakeholders involved in the process, such as: (i) the automakers and parts manufacturers, in the automotive technologies development; (ii) the federal entities, in the creation of more rigid and specific legislation, focusing on the circular economy; and (iii) the society in the search for eco-friendly products. Finally, it is concluded that, associated with the suggested policies and improvement actions, the adoption of the proposed environmentally appropriate system for the recycling of the ELVs, may accelerate the creation of a favorable way to the develop and consolidate the recycling in our country.

Ces travaux de thèse portent sur la photodégradation de retardateurs de flamme bromés  (RFB) : décabromodiphényléther (BDE -209), tétrabromobisphénol A (TBBPA), TBBPA bis (allyl) éther (TBBPA-BAE) et TBBPA bis (2,3-dibromopropyl) éther (TBBPA- DBPE) en milieu solide et dans des échantillons réels. Nous avons d’abord caractérisé par chromatographie en phase liquide-haute résolution couplée à la spectrométrie de masse (LC-HR-MS) le BDE-209 et ses produits de dégradation dans des échantillons de textiles issus de sièges auto des véhicules hors usage (VHUs) des années 90. Puis, nous avons mené des expériences prouvant que ces produits de dégradation étaient d’origine photochimique. Dans un deuxième temps, nous avons étudié l’effet du polystyrène sur la photodégradation du BDE-209, TBBPA et ses dérivés et l’effet de ces RFBs sur la photodégradation du polystyrène. Des analyses par différentes techniques spectroscopiques et chromatographiques (IR, ATR-FTIR, GC-MS, SEC) ont mis en évidence un net effet d’accélération réciproque. La SEC (chromatographie d’exclusion stérique) a révélé une augmentation drastique des coupures de chaîne du PS avec fragmentation. En outre, des photoproduits résultant de l'oxydation du PS et de sa bromation par Br· ont été observés pour la première fois. L’existence de ces sous-produits suggère un nouveau mécanisme de transformation de PS en présence de RFB. Certains de ces photoproduits migrent dans l’eau et l’air, pouvant causer une pollution environnementale. / The main objective of this PhD thesis was to evaluate the photodegradation of brominated flame retardants (BFRs): decabromodiphenyl ether (BDE-209), tetrabromobisphenol A (TBBPA), TBBPA bis (allyl) ether (TBBPA-BAE) and TBBPA bis(2,3-dibromopropyl) ether (TBBPA-DBPE) in solid medium and real samples. As a first step, we characterized by liquid chromatography high-resolution-mass spectrometry (LC-HR-MS) the BDE-209 and its degradation products in textile samples from car seats of end-of-life vehicles (ELVs) of the 1990s. Then we demonstrated that these products were formed by photodegradation. In a second step, we investigated the effect of polystyrene on the photodegradation of BDE-209, TBBPA and its derivatives and the effect of these RFBs on the photodegradation of polystyrene. Analyses carried out by chromatography and spectroscopy techniques (IR, ATR-FTIR, GC-MS, SEC) revealed significant and mutual acceleration effects. SEC (exclusion size chromatography) showed a drastic increase in chain breaks of PS. Morover, additional photoproducts that may result from PS oxidation and Br • bromination has been observed for the first time. The formation of these byproducts suggests a new PS transformation mechanism in the presence of BFR. Some of these photoproducts can migrate into water and air causing environmental pollution.

No. of bitstreams: 1 Carlos Roberto Franzini Filho.pdf: 953434 bytes, checksum: ad55f7d0771d38a54591c6a4aa6da6b2 (MD5) Previous issue date: 2015-03-31 / Currently in Brazil and the worldwide, the "end of life vehicles" (ELV) has been considered as a serious problem to environment. It is considered as an ELV the vehicle that concluded his life cycle or vehicle damaged due accidents. Unlike countries where recovery ELV happens because of specific ELV laws, recovery of ELV parts in Brazil has been guided by profit in reason of the possibility to reselling parts with highest market value after the first phase of use. The aim of this study was to identify what are necessary steps to propose a framework to implementation of reverse logistics process to ELVs in Brazil. The methodology used to achieve the aim was a theoretical / conceptual research from bibliometric review of the literature available in five databases (CAPES, EBSCO, PROQUEST, SCIENCE DIRECT, GOOGLE ACADÊMICO) and documentary research in Unions and class Associations. A content analysis from collected data allowed the identification of the main aspects and activities related to reverse logistics to ELV. Considering the current scenario for ELVs in Brazil and the data obtained from the literature during the content analysis, a framework was proposed with the required steps to implement the reverse logistics to ELV in Brazil. In reason of a theoretical study, there are limitations because of the different realities from researched countries: changing regulatory, social structures, political systems, laws, economic systems and also the level of development from the country. / Atualmente no Brasil e no mundo, os “Veículos em Final de Vida” (VFV) têm sido um grande problema para o meio ambiente. É considerado como VFV o veículo que chegou ao final de seu ciclo de vida útil ou o veículo que teve o seu ciclo de vida útil interrompido prematuramente em razão de acidentes. Diferentemente dos países onde a recuperação de VFV acontece em razão de obrigações legais especificas, no Brasil a recuperação das peças constituintes dos VFV têm sido impulsionada pela possibilidade de obtenção de lucro com a revenda destas peças para reuso, remanufatura ou reciclagem. Neste contexto, o presente trabalho tem como objetivo propor um framework com as etapas necessárias para a implementação do processo de logística reversa para VFV no Brasil. A metodologia utilizada para atingir o objetivo proposto foi uma pesquisa teórico/conceitual a partir de revisão bibliométrica da literatura em cinco bases de dados disponíveis (CAPES, EBSCO, PROQUEST, SCIENCE DIRECT, GOOGLE ACADÊMICO) e uma pesquisa documental em órgãos de classe do setor automotivo. Uma análise de conteúdo feita nos dados coletados permitiu a identificação dos principais aspectos e atividades relacionadas ao processo de logística reversa para VFV. Foram apresentados os principais estimuladores e barreiras identificadas na literatura para a implementação da logística reversa para VFV. Considerando o atual cenário para VFV no Brasil e as os dados apurados na literatura durante a análise de conteúdo, foi proposto um framework com as etapas necessárias para a implementação do processo de logística reversa para VFV no Brasil. Por tratar-se de um estudo teórico, as limitações deste estudo se devem ao fato das diferentes realidades entre os países pesquisados: diferentes regulamentações governamentais, estruturas sociais, sistemas políticos, sistemas econômicos e também o nível de desenvolvimento do país.

Notre recherche porte sur l’influence du cadre institutionnel sur les comportements des organisations. D'une manière particulière, elle s'intéresse à la manière dont les acteurs s'adaptent au cadre institutionnel du champ organisationnel dans lequel ils opèrent. Ces acteurs peuvent même être amenés à tenter de modifier ce cadre pour qu'il corresponde à leurs intérêts. La RSE est appréhendée dans notre réflexion comme un phénomène institutionnel, susceptible d'être mis en œuvre par le biais des pressions normatives, coercitives et mimétiques. Le champ d’observation de cette recherche porte sur les déchets d’emballages ménagers et les véhicules hors d’usage. Les résultats obtenus indiquent que le type de déchet, la taille des producteurs, le degré d’institutionnalisation et les caractéristiques du champ organisationnel influencent fortement l’action des institutions et des organisations encastrées dans le champ étudié. Les résultats se traduisent par les apports théoriques suivants : contribution aux études sur la formation des champs organisationnels ; contribution à l’étude du changement institutionnel à travers la confrontation institutionnelle ; contribution au courant théorique qui définit la RSE comme stratégie de business case ; mise en lumière du principe REP comme extension particulière de la RSE. / Our research concerns the influence of the institutional framework on the behavior of organizations. In a particular way, she is interested in the way the actors adapt themselves to the institutional framework of the organizational field in which they operate. These actors can be even brought to try to modify this framework so that he corresponds to their interests. The RSE is arrested in our reflection as an institutional phenomenon, susceptible to be implemented by means of the normative, coercive and mimetic pressures. The field of observation of this research concerns the waste of domestic packagings and end-of-life vehicles. The obtained results indicate that the type of waste, the size of the producers, the degree of institutionalization and the characteristics of the organizational field strongly influence the action of the institutions and organizations embedded in the studied field. The results are reflected in the following theoretical contributions: contribution to studies on the formation of organizational fields; contribution to the study of institutional change through institutional confrontation; contribution to the theoretical current that defines CSR as a business case strategy; the REP principle as a particular extension of CSR.
