A good Occupational Health and Safety (OHS) is needed to reach sustainability. OHS consists of three parts: 1) physical, 2) mental and 3) social.  The purpose of this study was to explore and foresee the main physical OHS risks when upscaling the recycling of wood in Lithuania, with the goal to prevent those risks.  The study was explorative and interviews with semi-structured questions were used as a method. Three of the four informants mentioned air pollution, traffic, working equipment, safety equipment, and chemical risk. The highest rate of physical risks mentioned was the physical ones and then the mechanical risks. Opinions differ whether the risks would change when upscaling the industry, from no stressed or additional risks to all risks being stressed and added risk.  Results should be seen as a hint of direction when it comes to OHS risks within wood recycling in Lithuania.

[pt] O presente trabalho tem como objetivo identificar e propor alternativas para que os princípios e práticas da economia circular (EC) possam ser implementados nas MPMEs brasileiras. Uma revisão sistemática da literatura e entrevistas com startups brasileiras foi realizada para levantamento dos dados. Foram identificadas 65 startups, nas quais 7 foram entrevistadas. Existe uma lacuna entre a teoria e a prática que se traduz numa falta de entendimento sobre a implementação nas empresas dos princípios de EC. As entrevistas mostram que a formatação do negócio está relacionada, geralmente, com experiências profissionais anteriores dos sócios e não possui, inicialmente, foco nos princípios de circularidade. Um framework de implementação foi elaborado. As principais conclusões são: o processo de implementação é progressivo e avança com o ganho de conhecimento e, consequentemente, maturidade das empresas em relação ao tema; que as experiências com das startups podem inspirar as MPMEs no avanço da circularidade. / [en] This paper aims to not only identify, but also propose circular economy (CE) principles and practices that can be useful to Brazilian MSMEs. The methodology included a systematic literature review and interviews with Brazilian startups. A total of 65 startups were identified, from which 7 were interviewed. One finding is clear: the current gap between theory and practice that translates into a lack of understanding on how to implement CE principles in corporations. The interviews also showed that the business circular strategy is usually related to partners previous professional experiences and, at first, has no focus on the principles of circularity. To assist businesses through these first steps, an implementation framework was developed. The research main conclusions are: the process of implementation progresses as companies invest in knowledge, improving their perceptions and level of maturity; the experiences with startups can inspire MSMEs in the advancement of circularity.

Le fait même de nous engager dans un projet explicatif, que nous nommons canoniquement philosophique, nous convoque à ce présupposé de l’affinité entre langage et monde. Nous proposons dans l’introduction une approche cohérentiste des systèmes philosophiques, définis comme des visions du monde où ontologie et épistémologie se doivent un support mutuel. Les positions épistémologiques de Locke, définies par son empirisme, sont juxtaposées à une conception corpusculaire de la réalité. Nous montrerons que les tensions qui existent entre ces deux positionnements sont consolidées par une attitude doxastique profondément réaliste, aboutissant à la fameuse thèse de la ressemblances des qualités primaires réelles et perçues. La science de l’époque est ainsi promue par une ligne rationaliste d’une affinité profonde entre ces catégories qui nous rendent intelligible notre environnement et la réalité même. Le naturalisme contemporain s’appuie quant à lui tout entier sur l’intelligibilité que nous avons du réel au travers de l’activité scientifique, fondant dès lors une résurgence de l’ontologie comme cet idéal d’une accessibilité rationnelle du réel, par le biais de procédures largement a priori, que nos sciences affleurent. Si les prétentions des métaphysiciens à pouvoir remplir cet objectif au moyen de préconceptions ontologiques doivent être déçues, il paraît plus juste de valoriser l’a priori mathématique qui, pace le modèle du réseau holiste de Quine, semble empiriquement incorrigible. Son efficacité ‘déraisonnable’ dans l’heuristique de nos sciences fondamentales le place en première ligne dans la constitution des différentes strates d’objectivation de notre environnement. / The very fact of being engaged in an explicative program, canonically called philosophical, calls us to this presupposition of an affinity between world and words. We propose in the introduction a coherentist approach to philosophical systems, defined as worldviews where ontology and epistemology are in charge of mutual support. In Locke’s empiricism, the epistemological line defined by his empiricism is coupled to a corpuscularist conception of reality. We’ll show that the lines of tension existing between those two positions are consolidated by a deeply realistic doxastic attitude, bringing to the famous thesis of the likeness between real and perceived first qualities. The science of that time is thus promoted by a rationalist line of a deep affinity between the categories that make our environment intelligible and the very reality. Today’s naturalism leans entirely on the intelligibility that we have of reality through scientific activities, so founding the reappearance of ontology as this ideal of rational access to reality, by means of largely a priori procedures, that our sciences flush. If the pretentions of the metaphysicians to meet those objectives have to be deceived, it seems more judicious to value the mathematical a priori which, pace Quine’s model of the seamless web of belief, seems empirically incorrigible. It’s unreasonable effectiveness in the heuristics of our fundamental sciences places effectively it in the very first line in the constitution of the different strata of objectivation of our environnement

Les avalanches de débris, qui résultent du démantèlement des flancs des édifices volcaniques et montagneux, sont des écoulements granulaires rapides et dangereux dont le monteur est la gravité et qui présentent des distances de transport extrêmement importantes. La dynamique de leur mise en place et leurs mécanismes de transport permettant cette très grande mobilité sont des phénomènes qui demeurent encore mal compris. De nombreux modèles existent pour expliquer la grande mobilité des avalanches de débris et incluent des processus basés sur la lubrification ou la fluidification de la masse granulaire mais également sur le phénomène de désintégration dynamique des éléments. Cependant la grande majorité des modèles proposés souffre du manque d’observations de terrain et de quantification de l’évolution des matériaux au cours de leur transport au sein de la masse granulaire. Afin d’identifier les principaux mécanismes de transport des avalanches de débris, nous proposons dans ce travail une étude de terrain détaillée de dépôts d’avalanches de débris volcaniques qui résultent du démantèlement d’un volcan bouclier océanique, le Piton des Neiges (île de La Réunion, océan Indien). L’approche est couplée à un examen morphométrique (dimension fractale et circularité), exoscopique et granulométrique des particules présentes dans les dépôts. Elle est complétée par l’examen de la fabrique des dépôts basée sur l’anisotropie de la susceptibilité magnétique (ASM). Les données obtenues nous permettent de mettre en évidence une évolution de la dynamique de transport et de mise en place des dépôts d’avalanches de débris depuis les zones sources jusqu’aux domaines de dépôt distaux. On montre également que la désintégration dynamique et le gonflement dispersif qui l’accompagne opèrent tout au long du transport et à toutes les échelles au-dessus d’une limite inférieure de broyage à 500 μm. En dessous de cette limite, la réduction granulométrique résulte uniquement de processus d’attrition par friction entre les particules. La grande mobilité des avalanches de débris pourrait ainsi être expliquée par l’effet combiné de la libération d’énergie élastique par la désintégration dynamique des particules > 500μm et par une réduction de la friction interne à la matrice liée aux interactions dispersives des particules fines (< 500 μm). L’ensemble des données permettent également de préciser les directions de transport et l’ampleur des avalanches de débris liées aux déstabilisations du massif du Piton des Neiges. / Debris avalanches, resulting from flank collapses that shape volcanic and mountainous edifices are rapidand dangerous gravity-driven granular flows that travel long run out distances. The dynamic and the transport mechanisms behind this high mobility remain poorly understood. The numerous models proposed to explain this high mobility include processes based on lubrication or fluidisation of the granular mass of the flow body, but also the dynamic disintegration of the transported particles. To date,all these proposed mechanisms lack observational support and quantification of the state of the particles of the granular mass during the transport. To identify the main transport mechanisms, we propose here detailed field studies of volcanic debris avalanches deposits resulting of flank-collapse events on an oceanic shield volcano, the Piton des Neiges (La Réunion Island, Indian Ocean). This study has been combined with morphometric (fractal dimension and circularity), exoscopic and grain-size analyses. Moreover, the fabric of the deposits has been investigated by with the characteristics of the anisotropy of the magnetic susceptibility (ASM). From these data we highlight a proximal to distal evolution of the debris avalanches transport and emplacement dynamics. We demonstrate that syn-transport dynamic disintegration continuously operates with the distance from the source down to a grinding limit of 500μm. Below this limit, the particle size reduction exclusively results from the attrition of the particles by frictional interactions. Thus, the exceptional mobility of debris avalanches may be explained by thecombined effect of elastic energy release during the dynamic disintegration of the larger clasts (> 500μm) and frictional reduction within the matrix due to the dispersive interactions between the finer particles (< 500 μm). All these data also allow to specify the transport direction and the approximate size of the debris avalanches related to the Piton des Neiges destabilisations.

It is, specifically, an analysis of the eighteen first chapters of his book Discorsi on the First Decade of Livy, which we believe to emerge a solution to the original problem of the constitution of forms of govern in the time. For this, we start with an examination of the historical and intellectual Quattrocento Italian. The intention is to demonstrate the conceptual framework that has influenced and Machiavellian political theory with which the thinker dialogues in his writings. Moreover, we highlight the return that the author makes the theory of circularity presented by the Greek historian Polybius. From Polybius, we expose his conception of historical temporality marked by circular movement of the forms of government, as well as the paradoxical problem that involves the formulation of mixed government. In this regard, we noted how Machiavelli takes this theory with the intention of recovering the discussion on the establishment of political regimes. Regarding the resumption seek to affirm that overcoming the Machiavellian thought to not accept the circularity as a determining factor of historical time. From this analysis comes the hypothesis that the temporal history as an expression of the movement of forms of government cannot be understood by natural law or by any other determinant a priori. Following these assumptions, we find the theory of conflict a vital component to understanding the dynamics involving both the political organization of state such as the movement elaborated by history. So, being the political element essential for the promotion of political organization, as well as for the realization of liberty in republics, also conclude that it is their responsibility to the mobilization of historical processes. The conflict in synthesis can be understood as the space of political action performed within the company, as this space has the constant possibility predominant trait of "creation." This sphere of action not only mobilizes the story (in order to raise their movement), but acts as a characteristic of "doing" history. In other words, the story has as one of its core components forming the field of human creation. Added to this the issue of corruption that marks the limits of human action in time. Machiavelli sees the degeneration process of the political as a condition of nature in all political body thus historical process is limited by that element which marks again, the field of contingency that the universe is subjected political. Finally, a search for the conception of history in Machiavelli reveals, in our view, the secularization of its elements, the identification of political conflicts as its mobilizer and the possibility of coming-into-being as a dimension of their process. / O objetivo desta dissertação consiste na investigação da concepção de história no pensamento maquiaveliano. Trata-se, especificamente, de uma análise sobre os dezoito primeiros capítulos de sua obra Discursos sobre a Primeira Década de Tito Lívio, da qual acreditamos emergir uma solução originária para o problema da constituição das formas de govero no tempo. Para isso, partimos de um exame sobre o panorama histórico e intelectual do Quattrocento italiano. A intenção está em demonstrar o quadro conceitual que influenciou a teoria política maquiaveliana e com o qual o pensador dialóga em seus escritos. Além disso, destacamos o retorno que o autor faz da teoria da circularidade apresentada pelo historiador grego Políbio. Deste último, expomos sua concepção de temporalidade histórica marcada pelo movimento circular das formas de governo, bem como, a problemática paradoxal que envolve sua formulação do governo misto. A esse respeito, evidenciamos a forma como Maquiavel retoma tal teoria com a intenção de recuperar a discussão sobre a constituição dos regimes políticos. No que tange a essa retamada procuramos afirmar a superação do pensamento maquiaveliano ao não aceitar a circularidade como uma condição determinante do tempo histórico. Desta análise nasce a hipótese de que a temporalidade da história, enquanto expressão do movimento das formas de governo, não pode ser compreendida por uma lei natural ou por qualquer outro determinante apriorístico. Seguindo essas premissas, encontramos na teoria dos humores um componente vital para a compreensão da dinâmica que envolve tanto a organização política dos regimes, como o movimento engendrado pela história. Assim, sendo o conflito político o elemento primordial para a promoção das ordenações políticas, bem como, para a efetivação da liberdade nas repúblicas, concluimos que também cabe a ele a responsabilidade para a mobilização dos processos históricos. O conflito, em síntese, pode ser entendido como o espaço da ação política realizado no interior da sociedade, espaço esse que possui como marca predominante a constante possibilidade de criação . Essa esfera do agir não somente mobiliza a história (no sentido de impulsionar o seu movimento), mas atua como uma característica do fazer histórico. Em outras palavras, a história possui como um dos componentes formadores de sua essência o campo da criação humana. Soma-se a isso o tema da corrupção, que demarca os limites da ação humana no tempo. Maquiavel vê o processo de degeneração dos regimes políticos como uma condição inerente a todo corpo político. Dessa forma, o processo histórico encontra-se limitado por esse elemento, o que marca, mais uma vez, o campo de contingência a que está submetido o universo político. Enfim, uma busca pela concepção da história em Maquiavel revela, a nosso ver, a secularização de seus elementos, a identificação dos conflitos políticos como seu mobilizador e a possibilidade do vir-a-ser como uma dimensão de seu processo.

In this project I will explore food waste and how we can study and partake in nature’s ecosystem, in our daily lives, using a playful approach. One-third of all food produced in the world is wasted. Our systems encourage consumeristic behaviours and wastefulness, they encourage exponential growth in preference to circularity. Human disconnection to nature’s ecosystems is resulting in depleting, eroding and polluted soils. Soil is the foundation of life, humans would not exist without it. Our food exists because of soil and we obtain energy from the food we eat - unfortunately, the nutrients in our food are declining due to intensive industrial farming. Compost enhances the soil, nourishes the life within it. We can think of nutrients as our source of energy. This flow of energy in nature goes from soils to plants, to animals, fungi, microorganisms, bacteria and back to its origin - the soil. Organic matter is fundamental to create viable habitat and preserve water in the soil. Why are not all of us composting? How can composting be involved in our everyday life? My ambition is to make a playful and low tech, human-powered composting machine. Where children can collaborate with older generations, together, learning how to turn their food waste to compost, while playing. With low tech machines run by human energy, I implement movements and play to evoke curiosity. While having fun I want to change our thoughts of waste to valuable resources.

Problematiken med matsvinn utgör ett globalt hållbarhetsproblem och konsumenternasbeteende har identifierats som den främsta bidragande faktorn till problematiken. En minskning av matsvinn måste ske för att en övergång till och utveckling av cirkulär ekonomi ska kunna realiseras, vilket ses som en direkt nödvändighet för att uppnå en hållbar utveckling. En förändring av de val konsumenter gör vid inköp av livsmedel ses som avgörande för att uppnå en minskning av det matsvinn som uppstår inom dagligvaruhandeln. Produkter med annorlunda utseende, kort utgångsdatum och skadad förpackning benämns som klass II-produkter, varpå en stor andel av dagligvaruhandelns matsvinn uppstår av just klass II-produkter. E-handel av mat har ökat drastiskt och utgör en viktig handelsplattform där det behövs åtgärder som syftar till att uppnå en förändring av konsumenternas beteende och val av livsmedel. Nudging utgör ett verktyg som används för att influera beteenden i en bestämd riktning och har identifieratssom en potentiell åtgärd att implementera inom dagligvaruhandelns e-handel, för att influera konsumenter att ta val av produkter som i en förlängning kan leda till minskat matsvinn. Syftet med denna studie är att utveckla förståelsen om vilka möjligheter och utmaningar det finns vid användandet av nudgingverktyg inom dagligvaruhandelns e-handel, för att influera konsumenters val av klass II-produkter. Val som i förlängningen kan leda till minskat matsvinn och utveckling av cirkulär ekonomi. För att utveckla denna förståelse, har vi utformat ett experiment som simulerar en fiktiv e-handel av dagligvaror, där olika nudgingverktyg implementerats i relation till klass II-produkter. Detta experiment har genomförts av studiens elva deltagare och därefter har dessa intervjuats. Den teoretiska bakgrunden om matsvinn, beslutstagande och nudging har ställts i relation till det material som samlats in genom intervjuerna, för att därefter användas för att besvara studiens problemformulering: Hur upplever konsumenter nudging i relation till klass II-produkter inom dagligvaruhandelnse-handel? Studiens resultat visar att konsumenternas upplevelse av nudging i relation till klass II-produkter inom dagligvaruhandelns e-handel, beror på konsumenternas preferenser, erfarenheter, förväntningar, konsumtionsmönster och ett antal demografiska faktorer. De största utmaningar och möjligheter för dagligvaruhandelns e-handel ses ligga i konsumenternas erfarenheter och preferenser, samt förverkligandet av transparens och tillit.

The fashion industry has historically been seen as synonymous with many unsustainable practices, such as overproduction, pollution, and mass-consumption. Today, many fashion brands are putting more attention to sustainability and are engaging in activities aimed at making the industry more environmentally friendly. This study investigates three Swedish fashion businesses, H&amp;M, Lindex, and Gina Tricot, with the purpose of examining and analyzing how they integrate circular strategies within their post-retail initiatives. Additionally, the aim is to investigate what strengths and weaknesses can be identified as related to these strategies in terms of reducing the fashion industry’s negative environmental impacts. The study is based on a content analysis of websites, documents, and policies of the fashion businesses as well as a qualitative semi-structured interview with a circular sustainability expert. By using a theoretical framework related to circular post-retail strategies as a tool of analysis, the results showed various levels of implementation of circular strategies among the businesses. Prolonging the lifespan of clothing by reusing, repairing, or re-designing, rather than repurposing and recycling, is seen as more effective in terms of environmental sustainability. Moreover, all businesses aim to inspire its consumers to make mindful choices, though the inspiration needs to be connected to an actual service if behaviors are to change. Concludingly, fashion businesses need to embrace circularity by finding new ways to profit from already existing garments through rental, repair, and re-design services to make the industry more environmentally sustainable. / Modeindustrin har historiskt setts som synonymt med många ohållbara fenomen, såsom överproduktion, föroreningar och masskonsumtion. Idag ägnar många modeföretag mer uppmärksamhet på hållbarhet och engagerar sig i aktiviteter som syftar till att göra industrin mer miljömässigt hållbar. Denna studie granskar tre svenska modeföretag, H&amp;M, Lindex och Gina Tricot, i syfte att undersöka och analysera hur dessa integrerar cirkulära strategier i post-retail-fasen. Syftet är dessutom att identifiera och undersöka styrkor och svagheter relaterade till dessa strategier gällande dess potential att minska modeindustrins negativa miljöpåverkan. Studien bygger på en innehållsanalys av webbplatser, dokument och policys från dessa modeföretag samt en kvalitativ semistrukturerad intervju med en cirkulär hållbarhetsexpert. Genom användningen av ett teoretiskt ramverk relaterat till cirkulära post-retail strategier som ett analytiskt verktyg visar resultatet på varierande genomförandegrad av cirkulära strategier hos de olika modeföretagen. Att förlänga livslängden på kläder genom att återanvända, reparera eller designa om ses som mer effektivt när det gäller miljömässig hållbarhet snarare än att återvinna. Samtliga företag syftar även till att inspirera sina kunder till att göra hållbara val, dock måste inspirationen vara kopplad till verkliga tjänster om konsumenters beteenden ska förändras. Sammanfattningsvis måste modeföretag hitta nya sätt att profitera från redan befintliga plagg genom omdesign-, reparations- eller uthyrningstjänster för att göra industrin mer miljömässigt hållbar.

Der Textilindustrie wird hinsichtlich umweltschädlicher Emissionen ein schlechtes Zeugnis ausgestellt. Bisweilen nimmt sie sogar einen unrühmlichen zweiten Platz ein und hat damit unweigerlich eine grosse Verantwortung um das global gesetzte 1,5-Grad Ziel (COP 21) zu erreichen. Konkret müssen bis 2030 die von diesem Industriezweig ausgehenden Treibhausgasemissionen um 45 % reduziert werden. Neben neuen Konsummustern und Geschäftspraktiken gilt es insbesondere die produktionsbasierten Emissionen zu vermindern (Berg, 2020).

[pt] A transição para uma economia circular (EC) requer modelos multidimensionais para a definição de objetivos e metas de circularidade em diferentes horizontes temporais, prazos, diretrizes circulares setoriais, políticas públicas nacionais e regionais, entre outros. Visando fornecer estruturas consistentes para decisões de negócios baseadas em evidências, com implicações para os níveis meso e macro de CE, o objetivo desta dissertação é propor um modelo de mensuração estratégica para monitorar e avaliar o desempenho da circularidade no nível micro, integrando GMA e dois métodos multicritério de tomada de decisão. Os principais resultados deste estudo envolvem: (i) uma matriz morfológica genérica composta por oito parâmetros e seus possíveis estados para definir e representar visualmente possíveis cenários de transição de CE para uma determinada organização que pretende evoluir através de transições de CE; (ii) o uso potencial de uma abordagem metodológica híbrida (que combina GMA com dois métodos MCDM) para selecionar os indicadores C mais relevantes para cada estratégia-R pode ser destacado; (iii) uma lista inicial de 58 C-indicadores e métricas associadas a dez estratégias-R e um conjunto de 38 C-indicadores selecionados por meio da adoção do método híbrido AHP-TOPSIS; (iv) definição de dez indicadores de circularidade compostos associados às estratégias R, bem como um Índice de Performance de Circularidade (IPC) geral, e um procedimento passo a passo para calculá-los em diferentes cenários de transição de CE. De uma perspectiva de transição circular, os resultados destacam implicações práticas para organizações e cadeias de valor, uma vez que o modelo foi concebido para ser aplicado em diferentes contextos de negócio, especialmente em organizações que irão definir seus objetivos de circularidade e respectivas agendas relativas à transição para uma economia circular. / [en] The concept of a circular economy (CE) transition requires multi-level frameworks regarding the definition of goals and targets for different time horizons, desired change timeframes, sectoral circularity guidelines, and national and regional public policies, among other factors. Aiming to provide consistent frameworks for evidence-based business decisions with implications for the meso and macro levels of CE, the objective of this dissertation is to propose a strategic measurement model to monitoring and evaluating the circularity performance at the micro level by integrating GMA and two multicriteria decision-making methods. The main findings of this study are: (i) a generic morphological matrix comprising eight parameters and their possible states to define and visually represent possible CE transition scenarios for a given organization that aims to evolve through CE transitions; (ii) the potential use of a hybrid methodological approach (that combines GMA with two MCDM methods) for selecting the most relevant C-indicators for each R-strategy could be highlighted; (iii) an initial list of 58 C-indicators and metrics associated to ten R-strategies and a set of 38 selected C-indicators by adopting the hybrid AHP-TOPSIS method; (iv) definition of ten composite C-indicators associated with the R-strategies, as well as an overall Circularity Performance Index (CPI), and a step-by-step procedure to calculate them in different CE transition scenarios. From a CE transition perspective, the results highlighted practical implications for organizations and value chains, once the proposed model is designed to be applied in different business contexts, especially in those organizations that will define their circularity targets and respective agendas concerning CE transitions.
