Abstract:
Electromobility will play a key role in order to reach the specified ambitious greenhouse gas reduction targets in the German transport sector of 42% between 1990 and 2030. Subsequently, a significant rise in the sale of electric vehicles (EVs) is to be anticipated in future. The amount of EVs to be recycled will rise correspondingly after a delay. This includes the recyclable power electronics modules which are incorporated in every EV as an important component for energy management. Current recycling methods using car shredders and subsequent post shredder technologies show high recycling rates for the bulk metals but are still associated with high losses of precious and strategic metals such as gold, silver, platinum, palladium and tantalum. For this reason, the project ‘Electric vehicle recycling 2020 – key component power electronics’ developed an optimised recycling route for recycling power electronics modules from EVs which is also practicable in series production and can be implemented using standardised technology. This ‘WEEE recycling route’ involves the disassembly of the power electronics from the vehicle and a subsequent recycling in an electronic end-of-life equipment recycling plant. The developed recycling process is economical under the current conditions and raw material prices, even though it involves considerably higher costs than recycling using the car shredder. The life cycle assessment shows basically good results, both for the traditional car shredder route and the developed WEEE recycling route: the latter provides additional benefits from some higher recovery rates and corresponding credits.

Abstract:
Due to the limited service life of new energy vehicle power batteries, a large number of waste power batteries are facing “retirement”, so it will soon be important to effectively improve the recycling and reprocessing of waste power batteries. Consumer environmental protection responsibility awareness affects the recycling of waste power batteries directly. Therefore, under the two recycling modes of new energy vehicle manufacturers and third-party recycling enterprises, this study analyzes the impact of consumer environmental protection responsibility awareness on the recycling price of waste power batteries and profit in the supply chain. The influence of factors such as recycling income, recycling input cost, and black-market recycling prices on consumer awareness of responsibility is also analyzed. Through theoretical research, it was found that: Under the model that third-party recycling enterprises are responsible for recycling, it can obtain better overall supply chain benefits; consumer environmental protection responsibility awareness and recycling benefits are positively correlated with supply chain benefits overall; and recycling benefits have a certain role in promoting consumer awareness of responsibility, while the increase in informal recycling prices inhibits consumer awareness of responsibility.

Abstract:
Regulating and supervising the energy vehicle (EV) power battery recycling market, improving the utilization rate of EV power battery recycling, and guaranteeing the safety and control of all aspects of recycling treatment require the establishment of an effective traceability system. The decentralization and tamper-proof characteristics of the blockchain can ensure the safety and reliability of relevant data while realizing traceability management. This study establishes the Stackelberg game model to compare and analyze the effects of different government mechanisms on the profits of each subject before and after participating in power battery traceability management. The study further uses the model to explore strategies to improve the enthusiasm of EV power battery recycling subjects to participate in traceability management. The results show that (1) the participation of each recycling subject in EV power battery blockchain traceability can help move more spent power batteries into formal recycling channels; (2) the government should adopt appropriate mechanisms to promote its participation in EV power battery blockchain traceability, the best result being when the government adopts a subsidy mechanism for consumers; and (3) the profit of the EV power battery manufacturer is inversely proportional to the target recycling rate set by the government. Furthermore, the pursuit of a very high target recycling rate is not conducive to the normal implementation of initial EV power battery blockchain traceability management. Therefore, it is crucial for the government to set a reasonable target recycling rate.

Abstract:
The vigorous development of the new energy automobile industry has highlighted the issue of efficient recycling of power batteries. Using a Stackelberg game, the pricing mechanism of dual-channel power battery recycling models under different government subsidies is investigated. Consequently, sensitivity analysis and comparison analysis are conducted, providing the pricing decision and the optimal profit of closed-loop supply chain (CLSC) systems. Finally, the effects of recycling efforts, power battery greenness levels, service levels, and consumer green recycling awareness on prices of power batteries and profits are determined through numerical simulations, and the optimal prices under different strategies are compared. The results indicate that recycling prices of each party in the manufacturer subsidy model are relatively high, and consumers’ green awareness and the green levels of power batteries are directly proportional to the recycling prices offered by recycling parties. Automobile 4S stores and recycling networks should pay attention to the balance between the increase in the cost and the quantity of government subsidies for their recycling efforts. For recycling enterprises, maintaining an appropriate service level can maximize their profits and positively motivate the development of them.

Abstract:
The rapid development of the new energy vehicle industry is an essential part of reducing CO2 emissions in the transportation sector and achieving carbon peaking and carbon neutrality goals. This vigorous development of the new energy vehicle industry has generated many end-of-life power batteries that cannot be recycled and reused, which has brought serious consequences for the environment. In order to solve the negative externality problem brought by EoL power batteries, how the government intervenes in the development of the market and guides multiple parties to cooperate in recycling EoL power batteries is a question worthy of deep consideration. In this paper, we consider that the government acts before recycling companies and consumers, and recycling companies and consumers act again according to the policy. First, we examine an evolutionary game model of recycling companies and consumers in the absence of the government and explore their choice strategies in various scenarios. Second, we examine how government subsidies to recycling companies and consumers may change the trend toward positive recycling in different circumstances. This paper compares the effects of government policies on subsidies to recycling companies, subsidies to consumers, and subsidies to recycling companies and consumers. Finally, the paper proposes policy suggestions from the perspectives of the government, recycling companies, and consumers. The conclusion suggests that the market does not guarantee a high return for both parties without government subsidies. It is difficult for recyclers and consumers to cooperate proactively in recycling end-of-life power batteries. Thus, it is found that government subsidies to recycling companies and consumers can maximize social welfare at the lowest government cost. Even though government subsidies are currently targeted at recycling companies, they should gradually be extended to consumers as the industry develops.

In the thesis the costs for extracting ground power cables from grass, asphalt or cobblestone using excavator or Kabel-X is examined. This is then compared to the sale value of the cable to a recycling company. The cables examined are 2 plastic (PVC) cables, 1 paper cable and 1 oil cable. The environmental perspective in the form of CO2, SO2, PO4, C2H4 and CFC11 is also examined where emissions from the extraction and the recycling process is compared to the avoided emissions from reusing the materials in the cables instead of extracting and processing new materials.

Abstract:
Given the unstable state of the environment, there is an undeniable need for the development of sustainable technologies. This need affects all areas of everyday life, even the shower. Modern shower systems result in energy waste in the form of heat, which can be minimized through the implementation of a heat exchanger. In cooperation with Consat SES this project developed a system to implement a heat exchanger using an in-shower water transportation pipe. A fitting non-electrical pump and motor were also chosen. To develop these elements a general design methodology of defining the problem, identifying the solution space, developing concepts, testing concepts and proposing a design, was used with adaptations for the component at hand. By following this strategy for each component and then reviewing the system as a whole, a new shower system was developed with a trapezoidal water transport pipe, a wing pump, and a turgo turbine.

Abstract:
The current paper recycling processes are surveyed pointing out the major stages and the variety of chemical/mechanical treatments the fibres undergo. The reduction or replacement of chemical/mechanical treatments presents possible advantages in prolonging fibre life. The results from recycled office waste which has been treated with ultrasound show a change in the particle size distribution of toner particles - making these particles easier to remove using established flotation techniques. Particle size distributions were measured using image analysis on thin (20gsm) paper handsheets. To establish the affect of sonication on fibres, a variety of virgin fibres were obtained from UK Paper, Sittingbourne. Results from virgin fibres which have been treated using ultrasound indicate an absence of cutting compared to conventional techniques. Fibres were found to have the same average length (0.6mm) after ultrasound treatment as the control sample, refined fibres were reduced to approximately 0.3 mm in length. Freeness decreased in both virgin sonicated and refined sonicated samples. The decrease in freeness was accompanied by an increase in the strength properties of both categories of fibres. Experiments with a prepared office waste furnish showed that ultrasonic treatment could decrease the size distribution of fused toner particles. The control sample had an average size of 80.9 um, after 1 minute sonication this was decreased to 54.9) um, decreasing further to 46.8)um after 2 minutes sonication. After demonstrating that ultrasound could decrease the particle distribution of the prepared office waste a more realistic and variable furnish was used. The experiments were conducted at room temperature, 50°C and 75°C. These temperatures were chosen to study the behaviour of fused toners as it approaches and exceeds its glass transition point, essentially the melting point of an amorphous polymer. It was found that the toner is easier to remove as the glass transition temperature is approached. Ultrasound is effective in breaking up large toner particles and detaching particles smaller than 25 microns in diameter.

Abstract:
Esta dissertação tem como tema central a gestão e o espaço dos resíduos sólidos urbanos em Novo Hamburgo/RS. A partir da análise histórica e atual desta gestão, procuramos compreender transformações espaciais e do valor da terra no município. O trabalho com os resíduos sólidos urbanos, sua destinação e tratamento, tem local definido dentro de uma cidade: a periferia. O mapeamento dos antigos locais de destinação dos RSU e um levantamento histórico da urbanização de Novo Hamburgo permitiram analisar suas influências recíprocas. Os espaços ocupados foram áreas verdes, afastadas do centro e de propriedade da prefeitura. Sucessivas expansões da mancha urbana, remanejaram os lixões para locais cada vez mais distantes do centro. De maneira geral, marcas das localizações anteriores podem ser observadas na desvalorização atual de tais locais. Assim, os locais antigos e atuais dos RSU em Novo Hamburgo, caracteristicamente capitalista, são periféricos, como se pode notar no bairro Santo Afonso, em vilas do bairro Primavera e no entorno do antigo lixão da Roselândia. Porém, em alguns casos, como na Vila Kroeff, com a expansão de vias de transporte, ou no Buraco do Raio, com a construção de equipamentos de lazer, esta tendência não se concretiza. Além de conhecer os locais dos resíduos sólidos urbanos no passado e no presente, a pesquisa voltou-se a analisar os agentes envolvidos na cadeia da reciclagem e suas relações com as transformações espaciais em Novo Hamburgo. Um agente relevante é o poder público municipal, regulador e gestor do trabalho na base da cadeia da reciclagem. Outros protagonistas na gestão dos RSU são as cooperativas e associações de reciclagem, que buscam a melhoria do seu trabalho; os intermediários, que influenciam nos preços; e a população em geral, em sua relação com os resíduos sólidos, através da separação e destinação. A gestão dos RSU sempre foi algo secundário na história da administração pública de Novo Hamburgo: existiram projetos que não saíram do papel, longos períodos de exploração de trabalhadores no lixão da cidade, além de um histórico de irregularidades nos serviços de coleta terceirizada. O atual programa CataVida foi uma mudança positiva na gestão dos RSU no município, voltando-se para a inclusão de catadores no mercado de trabalho formal.
This dissertation has as main subject the urban solid waste management and its space, in the city of Novo Hamburgo/RS. Considering a historical and current analysis of this management, it is aimed to comprehend the main changes in land value and spatial aspect in the city. The work with solid urban waste, its destination and treatment, has a very specific place into the city: periphery. Mapping old places destined to solid waste destination and an urban historical research, from Novo Hamburgo, allowed us to analyze mutual influences. The occupied spaces were green areas, secluded from the downtown and from city hall‟s ownership. Successive urban sprawl relocated the dumps to far more distant places from the downtown. Generally, traces of the former places could be observed in the current devaluation of such parts of the city. Therefore, the old and current places destined to solid urban waste at Novo Hamburgo, peculiarly capitalist, are peripheral, as noticed at Santo Afonso‟s neighborhood, in villages of Primavera‟s neighborhood and around of the old Roselandia‟s landfill site. However, in some cases, as Kroeff village, with the transport expansion, or at “Buraco do Raio”, with leisure equipment‟s building, this tendency does not confirms. Besides knowing the places destined to solid urban waste – past and present – at Novo Hamburgo, this research analyzed which agents are involved in the recycling chain and their relations with spatial changes at Novo Hamburgo. A relevant agent is the city hall‟s public authority, the one who regulates and manages the work at the ground works of the recycling chain. Other leading figures in the solid urban waste management are the recycling associations and cooperatives which seek to improve its work; the intermediaries, the ones that influence the prices; and the general population and its relation with solid waste, through waste proper selection and destination. The solid urban waste management was always secondary, in the history of public governance from Novo Hamburgo: there were projects that never saw the light of the day, long periods of landfill site exploited workers, beside an irregularities‟ history in the outsourced collection services. The current program “CataVida” was a positive change at the solid urban waste management in the city, focused on the collectors inclusion at the formal labor market.

Abstract:
Cap-and-trade is the most discussed CO2 emissions control scheme in the U.S. It is a market-based mechanism that has been used previously to successfully reduce the levels of SO2 and NOx emitted by power generators. Since electricity generators are responsible for about 40% of the CO2 emissions in the U.S., the implementation of CO2 cap-and-trade will have a significant impact on electric power generation systems. In particular, cap-and-trade will influence the investment decisions made by power generators. These decisions in turn, will affect electricity prices and demand. If the allowances (or emission permits) created by a cap-and-trade program are auctioned, the government will collect a significant amount of money that can be redistributed back to the electricity market participants to mitigate increases on electricity prices due to cap-and-trade and also, to increase the market share of low-emission generators. In this dissertation, we develop two models to analyze the impact of CO2 cap-and-trade on electric power generation systems. The first model is intended to be used by power generators in a restructured market to evaluate investment decisions under different CO2 cap-and-trade programs for a given time horizon and a given forecast in demand growth. The second model is intended to aid policymakers in developing optimal CO2 revenue redistribution policies via subsidies for low-emission generators. Through the development of these two models, our underlying objective is to provide analysis tools for policymakers and market participants so that they can make informed decisions about the design of cap-and-trade programs and about the market actions they can take if such programs are implemented.

This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating. The places have all a big heat excess and recycling will get more acceptable thermal comfort for the staff. 

Studies of efficiency, the variation in power and temperatures is made to see how much energy it is possible to recycle. Many systems could with small measures be more efficient.

A general problem for many places is that the energy is in the indoor air and has low temperature. It means that most of the energy is difficult to use in other places than for preheating of the intake air in the air handling units.

The residual oil frying (ORF), when disposed of incorrectly, cause negative impacts on the environment. However, its use as biofuel, generates great benefits of social, economic and environmental order. The objective of this study was to evaluate the performance of a group cycle diesel engine-generator powered by diesel and mineral diesel blends with residual oil frying. The trials were conducted in machines Instrumentation Laboratory and Agricultural Mechanization (Limma) of the Federal Rural University of the Semi-Arid (UFERSA) in Mossoró-RN, using a completely randomized design in factorial 4 x 5, with four replications. The treatments were diesel (DI) of oil and mixtures of diesel and residual oil frying (ORF) in the proportions: 50% DI and 50% ORF; DI 75% and 25% ORF; DI 90% and 10% ORF; 100% DI. The resistive loads used were 3, 6, 9, 12 and 15 kW. The engine oil temperature remains within the recommended operating range (85-95 ° C), indicating no lubricating oil contamination. All mixtures ORF had lower values for the exhaust temperature to the commercial diesel. The lower values of specific fuel consumption (EC) were obtained with higher loads, particularly at loads of 12 and 15 kW. The ORF25 mixture was the one with the lowest power generated and the EC farther diesel for all applied loads. Among the binary mixtures, ORF presented SE 10 similar to diesel in loads of 12 and 15 kW and the ORF50, the loads of 3, 9 and 12 kW; demonstrating that such mixing proportions, the ORF can replace mineral diesel
O óleo residual de fritura (ORF), quando descartado de maneira incorreta, causa impactos negativos ao meio ambiente. Todavia, a sua utilização como biocombustível gera grandes benefícios de ordem social, econômica e ambiental. Objetivou-se com este trabalho avaliar o desempenho de um grupo motor-gerador de ciclo diesel, alimentado com diesel mineral e misturas de diesel com óleo residual de frituras. Os ensaios foram conduzidos no Laboratório de Instrumentação de Máquinas e Mecanização Agrícola (LIMMA) da Universidade Federal Rural do Semi-Árido (UFERSA), em Mossoró-RN, utilizando delineamento experimental inteiramente casualizado, em esquema fatorial 4 x 5, com quatro repetições. Os tratamentos utilizados foram o óleo diesel mineral (DI) e misturas de diesel e óleo residual de fritura (ORF) nas proporções: 50% DI e 50% ORF; 75% DI e 25% ORF; 90% DI e 10% ORF; 100% DI. As cargas resistivas aplicadas foram de 3, 6, 9, 12 e 15 kW. A temperatura do óleo do motor se manteve dentro da faixa de trabalho recomendada (85-95 °C), indicativo de que não houve contaminação do óleo lubrificante. Todas as misturas de ORF apresentaram valores inferiores para temperatura de escapamento em relação ao diesel comercial. Os menores valores de consumo específico (CE) foram obtidos com as maiores cargas, sobretudo nas cargas de 12 e 15 kW. A mistura ORF25 foi a que apresentou a menor potência gerada e o CE mais distante do diesel para todas as cargas aplicadas. Dentre as misturas binárias, a ORF10 apresentou CE semelhante ao do diesel nas cargas de 12 e 15 kW, e a ORF50, nas cargas de 3, 9 e 12 kW; demonstrando que, nessas proporções de mistura, o ORF pode substituir o óleo diesel mineral

Abstract:
This diploma thesis is focused on the assessment of the possibilities of disposal of photovoltaic panels installed in the Czech Republic. In addition to the basic theory of photovoltaic cells and panels, the theoretical parts describe legislation, subsidies in the field of photovoltaics and the development of photovoltaics in the Czech Republic. As part of recycling, their methods, work with the collective system, as well as the impact on the environment are analyzed. In the experimental part, using the data of the installed capacity and the average weights of the panels, various projections of the disposal of the panels over time are made, which take into account factors such as the life of the power plant or the capacity of the recycling line. Furthermore, according to the available literature, an analysis of the revenue from the sale of recycled materials contained in panels installed in our territory is performed. Subsequently, the needs of future implementers of proven estimates of labor and logical demands were assessed. Finally, an economic evaluation of the fundamental aspects of the FRELP recycling process was performed and the net prices of different recycling directions were determined.

Abstract:
In this thesis we investigate advanced techniques for the readout and control of various interferometers. In particular, we present experimental investigations of interferometer configurations and control techniques to be used in second generation interferometric gravitational wave detectors. We also present a new technique, tilt locking, for the readout and control of optical interferometers. ¶ We report the first experimental demonstration of a Sagnac interferometer with resonant sideband extraction (RSE). We measure the frequency response to modulation of the length of the arms and demonstrate an increase in signal bandwidth of by a factor of 6.5 compared to the Sagnac with arm cavities only. We compare Sagnac interferometers based on optical cavities with cavity-based Michelson interferometers and find that the Sagnac configuration has little overall advantage in a cavity-based system. ¶ A system for the control and signal extraction of a power recycled Michelson interferometer with RSE is presented. This control system employs a frontal modulation scheme requiring a phase modulated carrier field and a phase modulated subcarrier field. The system is capable of locking all 5 length degrees of freedom and allows the signal cavity to be detuned over the entire range of possibilities, in principle, whilst maintaining lock. We analytically investigate the modulation/demodulation techniques used to obtain these error signals, presenting an introductory explanation of single sideband modulation/demodulation and double demodulation. ¶ This control system is implemented on a benchtop prototype interferometer. We discuss technical problems associated with production of the input beam modulation components and present several solutions. Operation of the interferometer is demonstrated for a wide range of detunings. The frequency response of the interferometer is measured for various detuned points and we observe good agreement with theoretical predictions. The ability of the control system to maintain lock as the interferometer is detuned is experimentally demonstrated. ¶ Tilt locking, a new technique to obtain an error signal to lock a laser to an optical cavity, is presented. This technique produces an error signal by efficient measurement of the interference between the TEM00 and TEM10 modes. We perform experimental and theoretical comparisons with the widely used Pound-Drever-Hall (PDH) technique. We derive the quantum noise limit to the sensitivity of a measurement of the beam position, and using this result calculate the shot noise limited sensitivity of tilt locking. We show that tilt locking has a quantum efficiency of 80%, compared to 82% for the PDH technique. We present experimental demonstrations of tilt locking in several applications including frequency stabilisation, continuous-wave second harmonic generation, and injection locking of a Nd:YAG slab laser. In each of these cases, we demonstrate that the performance of tilt locking is not the limiting factor of the lock stability, and show that it achieves similar performance to the PDH based system. ¶ Finally, we discuss how tilt locking can be effectively applied to two beam interferometers. We show experimentally how a two beam interferometer typically gives excellent isolation against errors arising from changes in the photodetector position, and experimentally demonstrate the use of tilt locking as a signal readout system for a Sagnac interferometer.

Abstract:
The life of hot gas path (HGP) components in gas turbine units can be extended through regular recycling. It is important to control the degradation of components under a limiting level by repairing on a regular basis and reusing them by recycling successively. Recycling mechanism of the first stage turbine blades is developed by investigating the characteristics of their typical degradations, repairability criteria, repair techniques, optimum timings of repair and economic evaluation model.

Full text
Abstract:
Passenger cars and trucks are one of the largest sources of global warming emissions in the US. Electric vehicles (EVs) have the potential to dramatically reduce these emissions, especially when charged by low-carbon renewable electricity. New UCS analysis finds that over its lifetime—from manufacturing to operation to disposal—the average new battery electric vehicle produces more than 50 percent less global warming pollution than a comparable gasoline or diesel vehicle. Based on the most recently available data on power plant emissions and EV sales, driving the average EV in the US produces global warming emissions equal to a gasoline vehicle that gets 91 miles per gallon. To speed climate benefits and to encourage more drivers to choose electric vehicles, the report recommends policy changes and investments to bring even more renewable energy onto the grid, develop robust battery recycling programs to help reduce manufacturing impacts, and make EVs more accessible and affordable.

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