Dupuy, Anna. "Habiter le monde en jetant : la place des déchets en Mongolie contemporaine". Electronic Thesis or Diss., Paris, EHESS, 2024. http://www.theses.fr/2024EHES0167.
Texto completo da fonteThis thesis seeks to rethink the way waste is framed environmentally in contemporary Mongolia, exploring how people part with objects and materials that move through their homes and bodies. It shows that waste, far from being defined by negativity or exclusion, is something Mongols live with and use to shape their everyday world. By combining long-term lexical analysis with a micro-ethnographic approach, this thesis examines how people relate to waste at different scales: from the individual body in motion—acts of disposal and household routines—to domestic spaces—in yurts, self-built houses, or apartments—and their surroundings, as well as in the city and the steppe. It delves into the Mongolian concept of waste, hog hajagdal, and explores how waste fits into the broader ways people inhabit space. The study of materials movements, their trajectories, rhythms, and the frameworks people use to think about them challenges the idea of waste as simply “something thrown away” or “a matter out of place” to inscribe them in the impermanence

Texto completo da fonteGiven the current ecological crisis due to the increase in the volume of waste, this research aims to understand how to encourage consumers to reduce their garbage. While most studies on this topic focus on the post-consumption phase, this research proposes to examine purchasing behaviors in order to capture consumers’ waste reduction strategies "at the source". This doctoral dissertation is based on two complementary empirical studies. The first one focuses on the determinants of recycling, the second one on the determinants of behaviors leading to avoid overpackaged products. In the first study, we developed an integrative model explaining intention to recycle. Based on the theory of planned behavior, progressive extensions enabled to take into account the effect of environmental concern (EC), moral norms and anticipated guilt. A quantitative survey (n = 450) confirmed the relevance of the model and highlighted different routes of influence. The second study dealing with the motivations underlying the choice of non-overpackaged products was based on perceived risk theory. Following an exploratory study (n = 11), the concept was extended to an environmental dimension. A quasi-experimental design among a representative sample of the population of Internet users (n = 808) was then used to manipulate the effect of range level and the salience of non-overpackaging. The results emphasized the significant role of perceived risk and the manipulated variables on the probability of choosing the product with no unnecessary packaging. In addition, both studies confirmed the indirect influence of EC on ecological behavior. The implications of both studies are discussed concurrently

Texto completo da fonteThe contrast between self-interest behavior guided by rational choice and altruistic behavior guided by normative considerations is a central theme in the social sciences. In fact, source reduction represents a good example ; its definition is ambiguous. In our study, source reduction appears like a reciprocal exchange. This argument is tested by examining a willingness to pay measure. So, we find that householders which participate in recycling activites are willing to pay more than others. Indeed, they ask to punishment for others by a " pay as you throw " system. This highest willingness to pay exprims a demand for punish the non-recycling householders. Nevertheless, if they are willing to accept more efforts for source reduction, they want a developped public system at home

Texto completo da fonteOur work consisted to analyze the individuals behavior when they have to make the selective sorting of them household refuse and are constrained by tariff imposed by the local authority. Then our research stood out in three stages. The first one consisted in a empirical analysis of the tariff practices in the United States (the Unit Pricing), and in Europe Cemagref/Crem studie) ant to explain the results of the existing studies. In second part, we analyze the recycling behavior, and we noted that it includes several characteristics of a collective action. The analysis of the selective sorting like an collective action show us that the individuals can be brought to cooperate although the standard theory tell that no individual should participate. Finally, in the third part we use experimental economics, on one hand to isolate the impact of the environmental context on the choices of the agents and on the other hand to estimate how the introduction of tariff tools change households behavior

Texto completo da fonteIn France, incineration is the second way of municipal solid waste treatment. It leads to a principal solid by product named municipal solid waste incineration bottom ash (MSWI BA). BA is a reactive material. During the weathering period, carbonation reactions allow the stabilization of its pollutant potential. The increase in selective collection of MSW could evolve characteristics of the resulting MSWI BA. The research work was constructed according to a double approach: - complete knowledge on mechanisms and parameters influencing carbonation phase, - preserve throughout the work a comparison of the phenomena according to the origin of the MSWI BA after a classical collection (MSWI A) and after an improved selective collection (MSWI B). The first part of the study is devoted to a comparative characterization of the MSWI A and B to observe an eventual influence of the improved selective collection on MSWI BA properties. The second part of this work, devoted to the study of MSWI BA weathering and particularly to the understanding of the carbonation phenomenon (always under a comparative way), is split up in three under left: - natural carbonation of MSWI BA (under air) on pilot scale (3 tons), - accelerated carbonation (under pure co2) on laboratory scale (2 to 3 kg), - residual organic matter role on the MSWI BA carbonation. These experimentations allowed to quantify, for the first time, the carbon dioxide volume implied in the MSWI BA carbonation. The results make obvious influence and consequences of sorting, in particular, glass sorting, on the carbonation of the incineration residues and the stabilization of them potential pollutant regarding development

Texto completo da fonteWaste management is a subject of interest for geographers for two reasons : the unstable space and time aspect and the multiplicity of people concerned at different scales (local, national, european and international) from the production to the treatment. At the beginning of the nineties, the waste management problem appears in France. The situation is urgent : rubbish dumps are numerous, treatment equipments are inadequate or reach saturation, and the public opinion is sensitive to environnemental problems. To clear up this problem, a new policy of recycling programs is planned in 1992 in France. Realized with partners (institution, firm), these thesis study concerns particularly separative collections. This new practice involves all the society (citizens, politicians, industrials). Techniques, behaviour and communication have been investigated on several french sites. Source separation modify people behaviour. Separating wastes, citizen is an active participant of their management. Municipalities are also implicated. This new point of view imposes new agreements with industrials. If users accept source separation idea, municipalities seem confused and industrials are still looking for technics improvements. Waste management is getting more and more complicated. Many interrogations remain

Texto completo da fonteThis thesis concerns the behavior of individuals toward their wastes and more precisely their recycling motivation. The issue is to study this behavior by exceeding the traditional marketing approaches on the subject. These traditional studies mainly focus on the attitude as an antecedent of the recycling behavior and on the theory of planned behavior to understand how this attitude can be turned into effective behavior. Indeed, these studies allow a better understanding of the recycling behavior but they show some limitations and in particular they do not consider the context of the adoption of recycling behavior which is characterized by a lack of autonomy and by the role of the public administration. To overstep these limits, this research aims at establishing the relevance of the application of a contemporary theory of motivation: the theory of self-determination. This theory takes into account the need for autonomy of the individuals in their daily activities but also the role of external factors on this feeling of autonomy such as the public administration. Thus, this research highlights that the autonomous motivation is the form of motivation which involves the most positive behavioral and attitudinal effects. This form of motivation can be hindered or fostered by the perception of the style used by the public administration in its will to obtain the compliance of the citizens with the public policy of waste management but also through the image the administration projects to the citizen

Texto completo da fonteThe simple analysis it self of the two cohabiting systems, shows the problems found in the town development control and mainly financial problems that the municipality experiment and endure. After the comparative study of these two systems which depicts differences and evident lacks concerning service organisation and stakeholders role, we think that it will be illusive to imagine in short term to establish a solid waste collect and elimination system, to the city as a whole, as usual as in developed countries. Based on this hypothesis, our thesis (the new strategy) proposes to cohabit in technical, economic, social and institutional coherence, the two collecting systems. This strategy aims at making coherent the efforts of all: populations, private sector, association and other stakeholders, municipal institutions, government, sponsors. We want it to be clear and simple to be understood by all, for stimulate everyone’s action and engage everyone in a behavioural changing process. Its practice needs nevertheless a real political will and a compromise of all stakeholders true dynamical stakeholders process

Texto completo da fonteWith a population of nearly four million inhabitants, the district of Abidjan is subject to various changes : economic, social, cultural, environmental and health, and rapid urbanization. This urbanization caused by the population explosion has resulted in the development of informal settlements and the deterioration of the urban environment. Thus are generated 1,168,000 tons of waste per year, or 0. 8 kg / habitant / day. These wastes are discharged into the single discharge Akouedo, opened in 1965, would not meet any standard. The District of Abidjan is facing serious difficulties in managing household waste by the specificity of the urban dynamic. Thus we are faced with a multitude of actors who invested the field. Our research attempts to identify the different actors in charge of waste management and how can they work in synergy and complementarity. Are also studied the relationship between the commune and households, as well as the practices of the population. New measures have been taken by the state but the problem remains. Information and communication can play a role in the city? How the population of Abidjan can contribute to improving the management of household waste? Our research approach aims to describe and to analyze the system of household waste management in place. It is based on a literature dealing with the management of household waste in a transdisciplinary major African cities. Given the lack of data on the issue of household waste in Côte d'Ivoire, we conducted a field study with a survey of 300 households, based on the type of habitat selected two communes : Cocody and Yopougon. The data were processed and interpreted, our results have led to thematic maps using space technology. Results indicate ignorance of the communal gathering that does not play its role. Households use precollectors, whether in the residential housing or spontaneous. The pre-collection is an alternative to the failure of communal gathering. If compensation of precollectors was well defined and formal activities, channeled and supported, they certainly provide a transformation in management style. A consortium with all actors, would permit manage the waste properly, would propose the creation of specialized companies that would provide new jobs. This overall synergy, through the construction of urban governance household waste, requiring a local approach where relationships are formed between each actor for a collective interest

Texto completo da fonteThe overall objective of this thesis is to draw insights about the factors that impacts the act of WEEE disposal by consumers at urban scale. Investigate such issue at the urban scale means contributing to the scientific debate concerning the governance of waste in the cities, which is a very important topic because of the role that urban areas now play as key actors in the transition to sustainable development goals. In particular, by adopting a multi-scalar and cross-disciplinary approach, the analyzed and the related consumer disposal behaviour is interpreted. The overall objective of the study is not to focus on the links between the macro dimension of management policies and those of individual and social behaviours, but alsi to understand what is the configuration taken by the different actors involved in the management of WEEE and what are the strengths and weaknesses of the chain. The discussion should provide useful key-readings to frame alternative methods of management of WEEE on urban scale as well as useful insights to foster citizens consumers' proper disposal

First, it relies on the analysis of means of regulation and economic tools set up by public authorities and concerning houseold packaging wastes (pollueur payeur principle and cost transactions internalisation). The evaluation then consists in the analysis of real datas, technical and economical, gathered in the course of a survey conducted to 130 local authorities. The variety of organizational and technical choices as well as the variety of agents concerned, induces the settlement of indicators comparable and applicable to the specificities of concerned authorities. The sample got analysed with non-parametrical statistical methods : ranging tests and data envelopment method

Two specificities characterize recycling : it is supported by the family (and not the individual) and its rules are imposed by public policies. This research is anchored in social practice theory that allows the study of a consumption routine at the crossroads between micro- and macro-social levels. The aim of this research is to highlight the building up of recycling’s social practice in families. The methodology is qualitative, based on participant observations, semi-structured interviews and mimes. Results highlight : (1) practice structure organized around doings, objects and engagement ; (2) links unifying those elements through appropriation, realisation and reinforcement and (3) practice dynamic, that allows families involvement into it. The main contribution of this work relies on the understanding of the building process at a familial level of the recycling practice at a societal level

Texto completo da fonteThe question of waste management is an important issue for any territorial authority, but it is even more so in an insular context. Indeed, these territories with restricted dimension of the territory are supported by constraining conditions, even handicapping: notion of scale, demographic impact, centralized economy, social structuring or even the energy situation. One inhabitant of Reunion Island produced in 2019, 241 kg of residual household waste. However, 100% of this waste fraction is directed to landfills, and in the short term, the island must face the saturation of these two landfills alone. The present research project proposes to divert the potential of residual household waste within the framework of an adapted strategy, the objective being to contribute to the effort of "refocusing" this potential on the territory. The approach thus proposes elements of answers in order to support a strategy of waste management on the territory of Reunion. In a first moment, it is proposed to mobilize an approach on the formation and the prospective of the production of residual household waste. The definition of the different methods addresses the need to differentiate the territory into several groups with similar characteristics. Secondly, in order to provide answers to the lack of representation in the implementation of major projects, particularly in the field of waste. A survey in three themes was carried out in order to question the couple consumer-producer in order to collect a description of the moment of the perceptions and the behaviors on the management of the waste taken on the territory. Finally, a multi-criteria approach is presented in a general framework of decision support to determine the appropriate systems for the recovery and treatment of residual household waste. In order to support a reasoned analysis and to provide a coherent result, a combination of mathematical methods of multi-criteria analysis has been instigated. In addition, a parametric sensitivity analysis was used to support strategic research in waste management and territorial configuration

Texto completo da fonteThe observation of a positive trend in the amount of waste in France and in the world has called for studies explaining household sorting behavior. This thesis lies in this perspective and aims at determining how to lead consumers to reduce their waste. We first present a review of the literature analyzing the portfolio of waste management public policies. We discuss the limits of the traditional approach stating that individuals adopt a rational behavior, seeking utility gains. Instead we support the idea that addressing behavioral factors is required for public policies supporting recycling behavior to succeed. In a second step, we investigate the the determinants of sorting behavior by building an original survey on 694 individuals in the PACA region. Our study combines and tests hypotheses first developed by sociologists and psychologists with concepts from behavioral economics. We use a probit model to estimate the probability to adopt a selective sorting behavior. Our empirical analysis shows that social influence negatively impacts recycling. Finally, we complete this study with an agent-based model which seeks to explain the sorting of waste as well as how such behavior is impacted by public policies. Our model considers heterogeneous households whose recycling decision is affected by four elements: individual environmental preferences and self-image, the opportunity cost of a tax on sorting, and the cost of sorting. Three public policies are tested: information, tax and "nudges"

Texto completo da fonteAutomatic waste sorting is a complex matterbecause of the diversity of the objects and of the presentmaterials. It requires input from various andheterogeneous data. This PhD work deals with the datafusion problem derived from an acquisition devicecomposed of three sensors, including an hyperspectralsensor in the NIR field. We first studied the benefit ofusing the belief function theory framework (BFT)throughout the fusion approach, using in particularconflict measures to drive the process. We first studiedthe BFT in the multiclass classification problem createdby hyperspectral data. We used the Error CorrectingOutput Codes (ECOC) framework which consists inseparating the multiclass problem into several binaryones, simpler to solve. The questions of the idealdecomposition of the multiclass problem (coding) and ofthe answer combination coming from the binaryclassifiers (decoding) are still open-ended questions. Thebelief function framework allows us to propose adecoding step modelling each binary classifier as anindividual source of information, thanks to the possibilityof handling compound hypotheses. Besides, the BFTprovides indices to detect non reliable decisions whichallow for an auto-evaluation of the method performedwithout using any ground truth. In a second part dealingwith the data fusion,we propose an evidential version ofan object-based approach composed with a segmentationmodule and a classification module in order to tackle theproblems of the differences in scale, resolutions orregistrations of the sensors. The objective is then toestimate a relevant spatial support corresponding to theobjects while labelling them in terms of material. Weproposed an interactive approach with cooperationbetween the two modules in a cross-validation kind ofway. This way, the reliability of the labelling isevaluated at the segment level, while the classificationinformation acts on the initial segments in order toevolve towards an object level segmentation: consensusamong the classification information within a segment orbetween adjacent regions allow the spatial support toprogressively reach object level

Texto completo da fonteGrounded on empirical investigations in two ordinary cities of emerging countries – Vitória in Brazil and Coimbatore in India – we argue that solid waste management in Southern cities cannot be conceived excluding the so-called “informal” actors at the risk of fiasco. Such an assessment is nowadays broadly acknowledged, yet its reasons are not always made explicit. We start from the empirical observation of appropriation conflicts, which arise with the introduction of municipal selective collection schemes and which transcend the “Big private operator versus small wastepickers” dichotomy. These clashes lead us to formulate the following central question: to whom do solid wastes –this res derelictae- belong to, taking into account that their very definition lies in abandonment. That is what our research aims at: confronting economic theory to an urban planning approach we show that the urban solid waste deposit corresponds to an impure public good (or evil!), a blurred object characterized by rivalry and non-exclusion. This is particularly due to transhipments in the evacuation service, as well as to the commodity value of a growing number of items – on condition that they should be recovered at source. Finally, taking a zoom-out in order to apprehend this issue through a global lens, we argue that the local dry waste sales business is directly determined by raw material prices fluctuations. The global economy impact on a local urban service leads us to acknowledge urban mining strategies which renew the appropriations' legitimacy question

Texto completo da fonteEnvironmental concern and ecological behaviors have received considerable attention, though there is a lack of studies focusing on the specific context of poor countries. This dissertation deals with households' preoccupations and behaviors as regards waste management in Burkina Faso, with a specific focus on the city of Ouagadougou. The research raises two main questions. First, what are the factors motivating collection, reduction, reuse and sorting of household waste? Second, what are the barriers to a good management of waste by households? Based on 57 life history-like semi-structured interviews, results show that the quest for a healthy environment, the prevention of diseases, a good education and the availability of waste collection structures are the main factors that motivate household's waste management. Poverty, ignorance, irresponsibility, climatic risks and the lack of structures are the main barriers to household waste management

It takes a critical look at the recyclable waste in a specific context: the sorting device system in Marseille, France. Less studied than other waste categories like organic waste, industrial or energy ... this thesis will focus on the social and cultural dimensions of recyclable waste by connecting and comparing it with all other domestic waste (organic waste, toxic, cumbersome ...). The aim is to reveal the representations and practices associated with these different types of waste; the games and actors’ logic facing the collection device in place; the paths and spatiotemporal storing areas followed by the waste according to their category

Texto completo da fonteThis thesis is a part of the studies carried out on organizational dynamics regarding occupational risks prevention, led in particular in the French National Institute for Research and Safety (INRS). The key issue is to put forward terms and conditions of prevention which take into account the work realities and industrial realities.From interventions carried out in five waste sorting centres for household packaging, in a context of industrialization of the waste recycling sector, this research aims to better understand the work of sorting operator, in order to determine vectors for actions in prevention. The waste sorting centres are productive entities, part of green business sector, where industrial challenges carry two major dimensions of sustainable development: territoriality and social sustainability.The method that we chose aims to put forward an objectification of the waste sorting operator’s work activity, taking into account the specifics of this sector, in the prospect of a sustainable prevention. To do so, an analysis of the work activity, according to the ergonomics work analysis method (EWA) was conducted, complete by several confrontation tools used with workers, both individually and collectively.The results showed that waste sorting centres are production sites located in a specific territorial context. Workers have to manage the production while taking into account the limits of their technical system, faced with waste as a territorialized object. Waste comes from separate households’ collection and is brought in the centre for the purpose of being sorted. It has territorialized characteristics, depending on specific territorial economical and social factors. Additionally, political factors regarding choices in terms of waste collecting and sorting, factors related to the consumption pattern and households’ lifestyle on the territory, factors related to the morphological features of the territory, and related to territorial attractiveness are also considered. However, this dimension is not taken into account during both the waste sorting centres design phase and the implementation of prevention strategies. The national testing phase for an extension of waste sorting instructions that we contributed to led to, argue that a disconnection was taking place between the characteristics of the technical system and the characteristics of the territory. This disconnection may lead to work intensification, directly impacting work sustainability.These results allow us to put forward two directions for actions in prevention in order to contribute to the design of sustainable sorting work systems. The first aims to better identify the coordination between actors belonging to different decision-making levels: some internal stakeholders, within the sorting centres, and external actors, on a territorial scale. To achieve this goal, the field of ergonomics has been shifted to mobilize theoretical frameworks originating from other disciplinary approaches, as proximity economics. This shifting aims to better take into account the requirements of industrial realities, and to produce mechanisms mobilizing these actors to satisfy the need for an effective transformation of work situations. The second direction aspire to put forward recommendations for the design of technical and organizational plastic systems, i.e. systems which leave sufficient rooms of manoeuver, factor for operators’ health, and that make work systems more efficient. The contributions of this thesis lead to develop an approach of prevention « in connection » which articulate the essential requirements of a regulatory prevention, and the industrial realities of the productive organization, for which three requirements have been identified: (i) develop the prevention problem from the knowledge co-production with workers, (ii) articulate work and industrial performance requirements, (iii) including prevention into territorialized industrial projects
