In developing countries, territorial planners are confronted with rapid urbanization and its inherent solid waste management (SWM) which has increased public health risks, and generated environmental and socio-economic problems too. To analyze these issues, a University campus (as a scaled city) was studied applying the Actor-Network Theory to find key elements to take into account for sustainable SWM programs not only in universities but also in cities. To achieve this goal, different actors and relationships between them were identified, as well as their dynamics throughout the SWM history. Some findings were that Environmental City's Authorities requirements have been the main cause of actions related to hazardous waste within the campus, while scholar's interests have initiated non-hazards. Otherwise, documents, operative committees, and scholars involved in milestones, have become as the main support for decision-makers. Researchers also verified that decision have not been made through systematic processes neither from a systems approach.

This paper reviews the fundamentals of the Exergy Cost Theory, an energy cost accounting methodology to evaluate the physical costs of products of energy systems and their associated waste. Besides, a mathematical and computationally approach is presented, which will allow the practitioner to carry out studies on production systems regardless of their structural complexity. The exergy cost theory was proposed in 1986 by Valero et al. in their “General theory of exergy savings”. It has been recognized as a powerful tool in the analysis of energy systems and has been applied to the evaluation of energy saving alternatives, local optimisation, thermoeconomic diagnosis, or industrial symbiosis. The waste cost formation process is presented from a thermodynamic perspective rather than the economist’s approach. It is proposed to consider waste as external irreversibilities occurring in plant processes. A new concept, called irreversibility carrier, is introduced, which will allow the identification of the origin, transfer, partial recovery, and disposal of waste.

The technique of mixing mine waste rock and tailings for disposal has the potential to avoid the problems of acid rock drainage and tailings liquefaction. This paper presents a rational basis for the design of mixtures based on particle packing theory and laboratory investigations. Mixtures were conceptualized using a particle model that allows mixture design and interpretation of behaviour. Laboratory investigations included examination of tailings rheology, mixture trials, and compressibility testing of waste rock, tailings, and mixtures of waste rock and tailings. Results indicate that mixture design governs mixture structure, and consequently also compressibility behaviour. A method is presented to predict mixture compressibility from mixture ratio and the properties of the parent waste rock and tailings. The study provides theory for the design and evaluation of mixtures as a mine waste disposal technique and demonstrates that the design of geotechnical properties is possible for homogeneous mixtures of mine wastes at the laboratory scale.Key words: co-disposal, particle packing, rheology, compressibility, waste rock, tailings.

The utilization of industrial solid wastes as building materials has been thought of as the best way to solve the problems caused by high waste production, high resource consumption and high pollution that is inherent with the primary industries of China. However, due to the low level of usage by previous technologies, these serious problems of the primary industries still persist. Hence, it is urgent to seek an effective way to solve these problems. In this paper, based on the understanding of the theory of simulation to formation of rock and the research advances of sialite technology, it is concluded that sialite technology can achieve the effective usage of industrial solid wastes.

This study is based on the general notion that restaurants should find more responsible solutions to dispose of the large amount of food that is not consumed. Moreover, the food wasted has great environmental, social and financial impacts, and yet this issue is still insufficiently presented in contemporary studies on food waste management. This paper applied the extended theory of planned behavior as a theoretical framework to elicit consumers’ behavior concerning food waste. A standard paper and pen survey recorded quantitative data provided by 221 respondents. The findings reported the following: (1) personal attitudes toward food waste positively affect an individual’s intention not to waste food; (2) perceived behavioral control positively affects an individual’s intention not to waste food; (3) the intention not to waste food negatively affects self-reported food waste behavior; (4) negative environmental attitudes negatively affect intention not to waste food; (5) hygiene-based food waste negatively affects perceived behavioral control. This study contributes to understanding consumers’ food waste behavior in restaurants and might have practical implications in the hospitality sector.

Background: Highly plate waste in hospitalized patients has become a problem in Hospitals’ nutrition service department, this causes adding treatment time for patient’s recovery and making the hospital service inefficient.Objectives: This research strives to develop a set of recommendations to improve the nutrition department service quality by reducing plate wastes in hospitals. Methods: This research uses a cross-sectional approach. The constraint causing analysis is done by observing dominant waste in each menu’s component and conducting FGD with the management team, nutrition department, and other related departments. The research population is 3000 plates.Results: One of the success indicators in the hospital’s nutrition services is less than 20% of plate waste. It was found that 26,65% or 327 of 1230 observed plates have more than 20% plate waste. The constraint was set with low scale value, food’s aroma, with 2,7 which make food’s aroma as a first priority problem to solve.Conclusions: The solution recommendation about constraint causes was sent to the nutrition department and hospital directors to review the hospital’s policies and SOP. The improvement can be focused on the hospital’s internal policies, Standard Operating procedures, employee competencies, obedience to set procedures, and also chefs and cooks skill

Abstract In an attempt to construct a new agenda for waste management, this thesis explores the importance of the definition of waste and its impact on waste management, and the role of ownership in waste management. It is recognised that present legal waste definitions are ambiguous and do not really give an insight into the concept of waste. Moreover, despite its explicit wish of waste prevention, when according to present legislation a thing is assigned the label of a waste, it is going to be treated like waste, implicitly legislation thus amasses waste. The philosophical ramifications inherent in such definitions mean that they are not capable of constructing a system that, by its very nature, results in a sustainable waste management system. It is also a fact that, while there are numerous practices as to how to deal with a particular type of waste, there is no theory of waste management. In this thesis, waste as a concept is analysed from the point of view of why and when waste is created. Using the PSSP language, waste is classified based on the Purpose and Performance attributes. New, dynamic definitions for waste and waste management are offered, which explain why waste is created and intrinsically offer a solution to how the problem could be solved. Additional waste-related concepts are introduced, which are thought to have great potential for improvement on waste regulation. The concept of ownership is explained as rights and responsibilities of waste creators/owners: it is thus crucial to raising awareness about waste. Ownership in itself often dictates which waste management options are preferentially adopted by a given community. The role of legislation in producing monitoring systems for the transfer of ownership as well as abandonment of ownership is analysed. To avoid obstacles to resource conservation due to materials being considered waste, a definition for non-waste is introduced. The new agenda for waste management thus focuses upon the development of more appropriate, sustainable definitions so that what is now commonly perceived as being waste will in fact be increasingly seen as resource-rich, 'non-waste'. The role of waste management is explained as control of all waste-related activities, with the aim of preventing, minimising or utilising waste. The need for a theory of waste management is explained, and the first building blocks of the theory are proposed. This thesis is offered as the first step toward scientification of waste management.

Os serviços inerentes à Limpeza Pública no Brasil são de responsabilidade municipal. Para tanto, as prefeituras podem licitar a operação destes serviços à iniciativa privada. Essa dissertação propõe a utilização da metodologia das opções reais para valorar um projeto de tratamento de resíduos sólidos para o Município de Niterói, considerando que existem diversas flexibilidades gerenciais e significativas incertezas em relação ao volume de resíduos a serem tratados. Dado que pelas regras do edital número 02/2008, o vencedor seria a empresa que apresentasse o menor preço para os serviços, a estratégia adotada foi valorar o projeto considerando o valor presente líquido do projeto base (aterro sanitário) igual a zero com a possibilidade de adicionar a segregação e comercialização de recicláveis e a implantação de uma usina de geração de energia ao longo da vida útil da concessão. Tal estratégia resultou num valor presente líquido de R$1.642.000.
Public waste management services in Brazil are the responsibility of city municipalities, which may contract out the operation of these services to private enterprises. Within this work, the economic feasibility of a solid waste treatment project in the municipality of Niterói is analyzed in accordance with the rules established by the bid document n 02/2008. A real options approach was used for the analysis considering that there are many managerial flexibilities and significant uncertainties about the volume of waste to be treated. The bid rules award the contract to the lowest bidder, so the strategy used was to value the project considering the net present value of the base project (landfill) as equal to zero, and to consider the option of adding recycling facilities and the implementation of a power generation plant throughout the period of the concession. The result of this strategy was a net present value of R$1.642.000.

Annotation:

This thesis focuses on the complex cultural, social and material factors that combine to hasten the decay of value and precipitate disposal in contemporary consumer societies. I argue that the dominance in waste studies of constructivism as a framework for understanding the endowment of objects with value, has lead to an underestimation of the materiality of devalued materials and objects. This overemphasis on abstract value theory in dominant discourses, I suggest, necessitates a return to a more grounded theory of va1ue that can be re-integrated with both the material affordances of objects and political economy. I therefore reconsider and re-theorise Marx's concept of use-value in order to redress these concerns; particularly the tendency to treat waste as an issue autonomous of production in capitalist societies. I argue that use-value can be reinterpreted as encompassing symbolic as well as material aspects of objects and that Marx therefore provides a significant basis for reworking theories of waste and impurity. I also argue for a renewed emphasis on the changing temporal characteristics of objects and their value in order to counter the overly synchronic and spatial basis of classic approaches to dirt, waste and disposal. My argument is brought into critical engagement with the cultura1 theory of Mary Douglas and Michael Thompson's influential Rubbish Theory: The Destruction and Creation of Value (I979), as well as more recent engagements in debates. With reference to the thesis I develop, I ask whether it can be legitimately claimed that capitalist consumer societies are also necessarily 'throwaway societies' and I discuss the possibility that objects devoid of use and exchange values can offer a critique of the capitalist economic system

Rapporten baseras på en fallstudie som gjordes på ett varuproducerande företag under vårterminen 2016. Rapporten är en C-uppsats skriven på informationslogistikprogrammet vid Linnéuniversitetet. Syftet med studien var att studera hur valet av kommunikationskanal och waste påverkar den upplevda kommunikationseffektiviteten bland de anställda på fallföretaget. Bakgrunden till studien grundar sig i att kommunikation är ett brett och viktigt område där det saknas forskning om kommunikationseffektivitetens påverkan av waste och kanalval. Kommunikationskanalerna utvecklas idag snabbare än teorierna som definierar dess användning, vilket gör uppsatsens ämne aktuellt. Teorierna som har använts i denna studie är Media richness theory [MRT] och Lean administration. Dessa har kombinerats och använts för att belysa hur den upplevda kommunikationsineffektiviteten kan ökas genom ett strukturerat kanalval på fallföretaget. Studien har haft en kvalitativ ansats med en abduktiv inriktning där resultatet kommer från individuella intervjuer med anställda på fallföretagets kontorsdel. Undersökningen visade att det finns brister i kommunikationen och att det påverkar kommunikationseffektiviteten på kontoret. Val av kanal görs individuellt utifrån vad personalen anser vara mest lämpligt då de inte ser helheten. Genom analysera och diskutera resultatet utifrån teorier framkom det att kommunikationseffektiviteten hade kunnat bli bättre om kanalvalen standardiserats.
The report is based on a case study made at a product producing company in the spring of 2016. The report is a bachelor thesis and is written by students from information logistic programme at Linnaeus University. The purpose of the thesis is to study what the effect of the choice of communication channel and waste could have on the employees at the company. Background to the study is that communication is a broad and important field where there is insufficient research on how waste and choice of communication channels affects communication effectiveness and efficiency. Development of new communication channels is faster than the studies about them and therefore lacks important information how and for what the new channels should be used for. This gap makes this study relevant. The theories that have been used in this study are Media richness theory [MRT] and Lean administration. These have been combined and used to show how the communication effectiveness and efficiency could improve if the company uses structured choice of channels for communication. The approach of the study has been qualitative with an abductive emphasis where the result comes from interviews with the employees at the company. The study is only carried out in the office at the company and will not include any other areas. The case study shows that there are deficits in the communication and that it affects communication effectiveness and efficiency at the office. The choice of channels to communicate through is done individually today. This because the employees are missing the big picture. The study has identified that a standardization of the communication would improve the communication effectiveness and efficiency. The result has been identified by using theories while analysing and discussing the result of the interviews.

Annotation:

The enormous amount of household food waste in developed countries is a global environmental and climate threat. To reduce household food waste, various behavior change campaigns and interventions are conducted. Most conventional behavior change interventions designed to reduce household food waste are based on the Theory of Planned Behavior (TPB) and are information heavy. These have shown, however, to not be effective enough to result in a fast and sizable enough decrease of household food waste in developed countries, thus reducing climate and environmental impact in a timely and sizeable enough way. The more systemic, holistic and practically oriented Social Practice Theory (SPT) theoretical framework is proposed by different authors as an alternative to the conventionally used TPB theoretical framework to design (behavior) change interventions. SPT is thought to lead to greater and faster reduction of food waste at the household level and to a general change in the food supply system. Nevertheless, interventions are oftennot created according to their proposed theoretical framework and no “direct” comparison between both theoreticalframeworks at the intervention level has been conducted. This thesis compares two case studies describing food waste reduction interventions, one with a TPB theoretical framework and the other with a SPT theoretical framework. The results show that when considering food waste reduction interventions at the household levels in developed countries the SPT might be a more effective theoretical framework for an intervention design compared to a TPB theoretical framework. Specifically, the SPT theoretical framework includes more relevant system stakeholders in the intervention creation leading to a more context specific design. Additionally, the emphasis of actual “doing” in an intervention based on an SPT theoretical framework createsa potential for more long-term change, compared to a TPB theoretical framework. However, this thesis also suggests that merging of the two theories should be further research and discussed, because of the potential greater effectiveness in actual food waste reduction.

Ettsyfte med denna uppsats är jämförelsen mellan två behandlingsalternativ för matavfall, hemkompostering eller biogasproducering sett från klimatperspektivet. Koldioxidekvivalenter har beräknats för de två alternativen. Ett annat syfte har varit att studera den politiska processen för att förstå varför det först under 90-talet uppmuntras till att hushållen ska hemkompostera för att sen under början av 2000-talet förespråka rötning av matavfallet. Mina uträkningar och jämförelser visar att det är mer fördelaktigt för klimatet att röta matavfallet, koldioxidutsläppet blir mindre än vid hemkompostering. Mitt andra syfte visar att det kan finnas en klimatvinst genom att låta politiken fatta besluten men det kan även finnas en risk att det egentliga syftet med hemkompostering glöms bort och att hushållen måste betala för något som de egentligen inte behöver (matkärl) eller som inte kanske finns (tillsynen).
One purpose of this study is to compare two treatment options for food waste. Home composting or biofuel production, seen from the climate perspective. The carbon dioxide equivalent has been calculated for the two options. The second purpose was to study the political process with regard to food waste to understand why Swedish households were encouraged to home compost food waste during the nineties only to early twenties advocate biofuel production. My calculations and comparisons shows that it is more beneficial for the climate to digest the food waste then composting since the carbon dioxide emissions is less. My second analysis indicates that while the political reorientation has led to environmental improvements, the effect has also been that to gain control of the food waste stream, waste management organisations effectively provide customers with no choice and economically punish households that have no food waste to collect since they have effective home composting.

This thesis investigates three contemporary Canadian texts— Ruth Ozeki’s A Tale for the Time Being, Margaret Atwood’s Oryx and Crake, and Rita Wong’s forage—that treat information as an object that can be wasted and recuperated. Using information theory and a new sub-field of critical waste theory called “Discard Studies,” I explore how the authors studied in this thesis place these two lines of thought alongside one another to examine how the concept of recycling information challenges the material, cultural, and ideological structures that distance humans from their waste. Specifically, I read the event of recycling as an interruptive act that triggers a reassessment of the (im)material connections that tether humans to their waste, vast (inter)national networks of exchange, and environmental crises related to our garbage.

The Nuclear Waste Fund constitutes a financial system that finances future costs of the management of spent nuclear fuel as well as decommissioning of nuclear power plants. The fund invests its capital under strict rules which are stipulated in the investment policy established by the board. The policy stipulates that the fund can only invest according to certain allocation limits, and restricts it to invest solely in nominal and inflation-linked bonds issued by the Swedish state as well as treasury securities. A norm portfolio is built to compare the performance of the NWF’s investments. On average, the NWF has outperformed the norm portfolio on recent years, but it may not always have been optimal. Recent studies suggest that allocation limits should be revised over time as the return and risk parameters may change over time. This study focused on simulating three different portfolios where the allocation limits and investment options were extended to see if these extensions would outperform the norm portfolio while maintaining a set risk limit. Portfolio A consisted of OMRX REAL and OMRX TBOND indexes, Portfolio B consisted of OMRX REAL, OMRX TBOND and S&P Sweden 1+ Year Investment Grade Corporate Bond Indexes, and Portfolio C consisted of OMXR REAL, OMRX TBOND and OMXSPI indexes. The return of each portfolio for different weight distributions of the assets were simulated in MATLAB, and polynomial regression models were built in order to optimize the return as a function of the assets’ weights using a Lagrange Multiplier approach for each portfolio. The results depicted that the maximal returns of Portfolios A, B and C were 4.00%, 4.13% and 7.93% respectively, outperforming the norm portfolio’s average return of 3.69% over the time period 2009-2016.

KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology. The greatest merit of the VDHconcept is that the almost stagnant groundwater in the deep boreholes prevents the transport ofthe possible release of radionuclides into the rock or up to the ground level. Since variousdisadvantages of the KBS-3V concept were found in previous research, the superiority of VDHconcept attracted the researchers to continue studying it into the late 1980s.The geological repositories of both of KBS-3V and VDH types primarily consist of a naturalbarrier (host rock) and of an engineering barrier (also known as a buffer/backfill barrier).According to the principle of IAEA and national relative research organizations, thebuffer/backfill material should have low permeability and good expandability, as well assuitable physical and sealing properties.The thesis concerns the VDH concept and is focused on the construction and performance ofthose parts of the sealed repository that are not affected by high temperature or gamma radiation.In the lower part of a VDH repository, the clay packages containing HLW will be exposed tohigh temperature (100-150 􀄇 ) in the borehole and to highly saline groundwater. In theinstallation phase of HLW, the groundwater will be pumped out and replaced by medium-softsmectite clay mud in which the HLW packages are installed vertically. During the hydrationand maturation of the clay components, the microstructural reorganization, water transport,migration of clay particles and redistribution of the density of the components take place. Thematuration determines the transient evolution of the clay seals and influences the rheologicaland soil mechanical behavior in the installation phase. The maturation of clay system alsodetermines their ultimate sealing potential of VDH repositories.This study presents the work carried out for investigating the maturation of the buffer-backfillclay in the HLW deep borehole. Initially in the study three types of clays, the Namontmorillonite,magnesium-rich and illite-smectite mixed layer clays, were examined for estimating their performance as the barrier candidate material. This is mainly presented in theliterature review. The experimental study was conducted on montmorillonite GMZ clays andI/S mixed-layer Holmehus clay. The expandability and permeability tests were carried out forinterpretation of the recorded swelling development and assessment of the effect of the salineconditions, with the goal of deriving a relationship between swelling pressure and hydraulicconductivity for different dry densities. The maturation tests of initially fully-saturatedHolmehus clay and partly saturated GMZ clay were performed. During the tests, the shearstrength mobilised by the relative movement of densified mud and migrated dense clay -contained in a perforated central tube - were determined. According to the results of shearstrength tests, the maximum operation time or the number of clay packages to be placed in asingle operation was evaluated, whilst the suitable saturation degree of the dense clay wasdiscussed as well.A model of the maturation of initially water-saturated clay seals based on Darcy’s law wasworked out and the evolution of the clay components in a lab-scale borehole using Holmehusclay were performed and compared with the experimental recordings. Good agreementsbetween the physical behaviors of the theoretical simulations and the measurements wasachieved by which the validity of the model was verified. Using the results, the hydration andsoil migration in the entire maturation process were presented in diagram. The model was alsoused for preliminary evaluation of the maturation products in real boreholes by assuming thesame Holmehus clay as used in the tests. Two constellation of borehole and dense clay withdifferent diameters, 80 cm borehole /60 cm clay and 80cm/50cm, were assumed. The resultsrespecting dry density and hydraulic conductivity of the ultimate maturation products, and thedegree of homogeneous of the buffer and backfill clay system in the assumed boreholes, arepresented and discussed. The options of different mineral types and initial physical propertiesof the candidate buffer clays provide a reference for engineering barrier design of HLW disposalin VDH.

In boilers that use municipal solid wastes as fuel, metal wastage due to corrosion and erosion and tube fouling due to the buildup of deposits present serious problems to the system designer and operator. This study examines the corrosion mechanisms in Waste-To-Energy (WTE) boilers and summarizes the findings of a corrosion survey of several WTE facilities and of interviews with senior engineers in the WTE industry. In addition, this study examines the existing methods of reducing corrosion that are adopted in WTE plants. Finally, the study proposes experimental research on corrosion resistant materials to be carried in the near future.

Without the informal economy, there would be no waste recycling in most Asian cities. In many Asian countries, waste management systems are underdeveloped, with the informal economy dominating the processes of waste collection, sorting and recycling. In this short report, we present preliminary findings from our survey of 34 waste pickers in Bangkok. The report sheds light on their working conditions, health risks, gendered dimensions and the challenges they face in waste recycling.

Waste disposal sites across Jordan pose serious risks to the environment and to public health if not managed safely. Municipal waste decomposing in open landfills also takes an environmental and socio-economic toll on neighbouring communities. While the Government of Jordan is planning to reduce the number of operational landfills and improve waste management services, persistent issues associated with unsustainable waste practices and their associated effects on the wellbeing of surrounding communities and the environment need to be addressed. Guaranteeing a sustainable waste management scheme for communities in Jordan should include increased consideration of the long-term effects that waste disposal sites have on neighbouring communities.

A great deal of energy can be sourced both directly and indirectly from waste. For example, municipal waste with an energy content of around 60 petajoules is incinerated in Switzerland every year. The energy recovered directly from this waste covers around 4 % of the Swiss energy demand. However, the greatest potential offered by waste management lies in the recovery of secondary raw materials during the recycling process, thus indirectly avoiding the energy-intensive production of primary raw materials. In order to optimise the contribution to the energy turnaround made by waste management, as a first step, improvements need to be made with respect to the transparent documentation of material and cash flows, in particular. On the basis of this, prioritisation according to the energy efficiency of various recycling and disposal channels is required. Paper and cardboard as well as plastic have been identified as the waste fractions with the greatest potential for improvement. In the case of paper and cardboard, the large quantities involved result in considerable impact. With the exception of PET drinks bottles, plastic waste is often not separately collected and therefore offers substantial improvement potential. Significant optimisation potential has also been identified with regard to the energy efficiency of incineration plants. To allow municipal solid waste incineration (MSWI) plants to use the heat they generate more effectively, however, consumers of the recovered steam and heat need to be located close by. A decisive success factor when transitioning towards an energy-efficient waste management system will be the cooperation between the many stakeholders of the federally organised sector. On the one hand, the sector needs to be increasingly organised along the value chains. On the other hand, however, there is also a need to utilise the freedom that comes with federal diversity in order to test different solutions.

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