From plastics in the oceans, to the export of toxic materials, waste is an issue that increasingly attracts public attention as well as demands for political and environmental action. Within the social sciences, writing on waste has clustered around the emergent and growing sub-discipline known as ‘discard studies’. This entry looks at how anthropologists have broached the issue of waste, from a long-standing interest in pollution, to more recent explorations of how humans and waste constitute one another. It is divided into three main anthropological approaches to waste: a symbolic-structuralist approach focused on the relations between order/disorder and the sacred/profane; an economic-materialist approach that is more concerned with waste, value, and the connections and flows between local and global scales; and intersubjective-posthuman approaches that focus on how waste makes people as well as how people make waste. Through fine-grained ethnographies of engagements with waste and theoretical contributions, the anthropology of discards highlights how diverse waste’s materialities and representations really are, and helps to challenge taken-for-granted associations between waste, stigma, and an absence of value.
Just as ever-growing quantities of waste have increasingly attracted the attention of governments, activists and communities, the issue of waste at a global scale has risen rapidly up political and research agendas since the turn of the millennium. Shocking photographs and videos that make visible the harm that wasting causes, such as those of the North Atlantic garbage patch (estimated to measure hundreds of kilometres) and the plastic-filled bird carcasses of photographer Chris Jordan, have captured the public imagination around the topic of plastic waste in the oceans. At the same time, waste has become an issue of international diplomacy and scandal, as a series of countries in the Global South have begun sending contaminated waste back to its sources in the Global North (see the ongoing dispute between the Philippines and Canada, Choi 2019). The initial classification of our current age as the Anthropocene by geologists was based in part on the fact that signs of human activity and wasting – plastics, metals, radionuclides – could be observed deep into the Earth’s crust (Zalasiewicz & Waters 2015). Indeed, global warming, which places human, animal, and plant life as we know it in mortal peril, is caused by a form of waste: the release of carbon emissions as petroleum deposits are consumed.
In tandem with these broader developments, research into waste has escalated both in anthropology, and across the social sciences and humanities more generally, giving rise to the interdisciplinary subfield of ‘discard studies’. Yet do we necessarily know what waste is? As the popular expression ‘one man’s trash is another man’s treasure’ hints at, rubbish can very often be in the eye of the beholder. As Alexander and Sanchez note,
depending on context and perspective, waste is (at least): the antithesis of value, that which enables value, irredeemably toxic or sterile, a resource by another name, an unrecoverable residue, not yet productive, disgusting, forgotten, or abandoned (2018: 3).
This encyclopedia entry explores three analytic approaches to waste that have been taken by anthropologists: symbolic-structuralist; economic-materialist; and intersubjective-posthuman.
In a symbolic-structuralist approach (e.g. Douglas 2002 ; Leach 1989 ), waste can be understood as what emerges through interactions between the sacred and profane, which are structurally bound to one another, a focus that can be traced back to the work of Emile Durkheim (1915), a founding father of social anthropology and sociology. In this perspective, waste is usually considered to be social and relational rather than an objective quality or categorization of phenomena in the world. The second analytical approach, heralded by Michael Thompson’s (1979) Rubbish theory, launched an economic-materialist approach to understanding the circulation of materials between different regimes of value. Within this approach, an increasing number of scholars (e.g. Gille 2007; O’Brien 2008) have focused on the materiality of waste within broader political and economic structures that act to shape how and where it appears. A third approach to the study of waste can be called ‘posthuman-intersubjective’. It has been gathering strength since the 2010s and concentrates on the subjects that waste and various forms of waste-work engender. This includes workers whose identities are tightly bound up with waste – such as waste-pickers (Millar 2018) – as well as the more general encounters with discarded materials that happen as we separate out our recyclables (c.f. Hawkins 2006), or unexpectantly meet with a tangle of trash in the street (c.f. Bennett 2009). Waste in these perspectives is given varying degrees of agency: it is seen as acting and acting upon us in ways that are outside our conscious control.
By emphasising some aspects of human-waste relations while neglecting others, each approach – symbolic-structuralist, economic-materialist, and posthuman-intersubjective – captures a part of but not the whole picture. Thus, anthropological work on waste generally foregrounds the different epistemological consequences that specific representations of waste can have, including the removal of agency from so-called ‘wasted lives’ and value created from territories depicted as ‘waste-lands’. Far from being a load of rubbish, the anthropology of waste also brings cultural perspectives into conversation with questions of power, class, religion, materiality, and economics that are at the heart of contemporary society.
The anthropology of waste per se is relatively recent. The relatively small societies that anthropologists traditionally studied did not generate levels of waste on the scale of today’s consumer societies, and whilst materials (i.e. food waste) were inevitably discarded, such practices do not appear to have been deemed worthy of serious attention. A relevant precursor, however, is the study of purity and pollution. Pollution in anthropological discourse has had a specific meaning – the negative association with people or substances – generally as a result of a mixing or conflation of things that should be kept pure.
The person who initiated the study of purity and pollution is Mary Douglas, known for classifying dirt as ‘matter out of place’. Douglas was an English social anthropologist who conducted fieldwork with the Lele ethnic group who live in the modern Democratic Republic of Congo (DRC), but her social theories were influential beyond African anthropology. In particular, her most well-known book, Purity and danger (1968), shares with structuralists like Claude Lévi-Strauss the idea that prohibitions, taboos, and attachments have very little to do with the concrete thing that is prohibited, and much more to do with an interplay of symbols that reflect deeper organising principles of society. Douglas argued that the prohibition of pork in Leviticus, for example, could not be explained by the ‘dirtiness’ of the animal but lay instead in the way that pigs confounded the religious classifications of animals (hoofed/ non-hoofed; cud-chewing/ non-cud-chewing, etc.)
For Douglas, the human mind is an ordering mind, and rituals of pollution and purity tend to cluster around the anomalies that confound cultural systems of classification. Those who take for their area of enquiry matters of pollution, dirt, and waste engage with her ideas in part because the ‘matter out of place’ phrasing so succinctly defamiliarises us from the notion that what constitutes waste should be obvious and universally accepted. For Douglas, dirt is that which offends order in a culturally-specific system of classification, where classification comes first, and determines pollution. Rather than waste, however, she was primarily interested in the symbolism of ritual pollution in religious and what she called ‘primitive’ classificatory systems. This, as Martin O’Brien notes, makes Douglas a somewhat awkward fit for discussions of the billions of tons of municipal solid waste that arrive daily at the world’s landfills (2008: 128).
Pollution as a traditional anthropological concept is different from contemporary, everyday understandings of environmental pollution embodied in car exhaust fumes, smoking industrial chimneys, and frothing, chemically-polluted rivers. Its characteristic areas of study include menstruation – since menstruating women are viewed as polluted in many societies and are, therefore, quarantined (c.f. Kristeva 1982) – and death, where those working with or touching the dead are considered polluted and thus to be avoided or approached with ritualised caution (Parry 1994). Nevertheless, looking to some of the early approaches to pollution can help us understand the roots of the first anthropological analyses of waste.
Early anthropologists (e.g. James Frazer) exhibited two tendencies regarding pollution (c.f. Forth 2018). One was to locate pollution in the properties of substances and things as opposed to the relations between people and categories. A second was to differentiate between forms of pollution aversion that exemplified either ‘primitive’ hygiene measures or reflected religious ideas of the sacred and profane. However, these studies tended to centre on polluted people rather than the things that polluted them, whether these were menstruating women, Indian untouchables, or stigmatised gravediggers (Jewkes & Wood 1999). Where there was an interest in things, these were often substances ejected or detached from the body, including menstrual blood, nail clippings, and excrement. This focus on bodily substance was later taken up by Michael Thompson (1986: 1) to argue for the culturally relative nature of waste. That there is nothing intrinsically polluting about blood, hair, or snot indicates that there is no ‘waste in nature’, he argues, explaining that these might be valued, feared, or treated with indifference by different cultures or indeed classes.
This clustering of ideas of pollution and purity around substances emanating from the body has nevertheless given rise to quite different theoretical approaches, including those inclined to a universalist rather than relativist nature. Exemplary of the latter approach is Julia Kristeva’s (1982) psycho-analytical theorisation of abjection, which draws on the work of Douglas. For Kristeva, threats to the preservation of the integral subject inspire pollution beliefs, so that a body that leaks wastes and fluids – externalising what should be inside – violates an important inside/outside boundary and risks the dissolution of the self into the other. One example that she gives is the instinctive, visceral reaction she has to the thin film that forms on milk and that the body repels: since this has entered the mouth, and mixed with saliva, one is essentially expelling a part of oneself. Within anthropology, Valerio Valeri (2000) draws on Kristeva and fieldwork with a small group of hunter-gatherers in Eastern Indonesia to make broader theoretical claims, ultimately arguing that ‘the embodied subject’s fear of disintegration through the body and by the body is the ultimate basis for the notion of pollution’ (2000: 111). Valeri objects to the way that Douglas treats pollution as a secondary phenomenon resulting from processes of classification. By exploring pollution beliefs around bodies, substances, and animals, he shows that not all things considered polluting are classificatory anomalies, nor all classificatory anomalies regarded as polluting.
Douglas’s legacy has extended beyond the discipline and endured in time. There have been creative adaptations of her ideas, such as Laurence Douny’s study of domestic waste among the Dogon, an ethic group in Mali numbering roughly half a million people. Douny suggests that Dogon ‘categories of waste enact a conceptual ordering of daily life that allows them to set up and maintain their socio-cultural and symbolic boundaries’ (2007: 313). It is, she argues, through the naming of rubbish that they ‘take control over the fuzzy reality of the matter’ (2007: 313). For example, the Dogon praise certain forms of dirt – food left on pots, sweat, and smoke – as signs of a lively, busy, and prosperous household, while people who are always clean are thought to be work-shy. Negative forms of dirt include the highly ritually polluting – menstrual blood and body solids – and the simply bothersome – daily sweepings and tourist trash. This description of order imposed on an assumedly formless world through the cultural imposition of different categories and classifications resembles a symbolic-structuralist approach. Yet Douny is careful to note that classification is ‘versatile’, ‘a daily practice’, in constant flux and redefinition: ‘rubbish categories, even though solid, endow a certain flexibility’ (2007: 313). Plastic waste brought by outside visitors, for example, might be assimilated into existing waste categories but can also be recovered as a resource that can be fashioned into craftwork sold back to tourists.
Despite its plentiful insights, Douglas’s approach is not the primary framework that guides the contemporary social science of waste. Contributing factors have been its binary nature; her lack of focus on waste per se; and the theoretical consideration of only one side of a ‘primitive’/’civilized’ binary that itself has long been discarded. To theorise the ever-greater flows of waste across the planet it would be necessary to develop approaches that attended to politics, economics, and the material stuff of waste itself.
If earlier anthropological engagements with ‘rubbish’ in the religious sphere were concerned with the sacred/profane and pure/polluted dichotomies, economic anthropology brought in another important binary: waste and value. These are critical categories for Thompson’s recently reissued Rubbish theory (2017 ), whose theoretical ambitions, Josh Reno argues, go ‘far beyond anything heretofore attempted by anyone in discard studies’ (Thompson 2017: xi). Against the binaries of symbolic-structuralist models, however, Thompson introduces a tripartite schema to help understand how objects, from houses to antiques, can undergo radical transformations in value. He starts out with two categories of goods common to economics: transient and durable. A classic example of a transient good is a car, which decreases in value from the moment that it is purchased until it is reduced to scrap, while durables, such as certain antiques, ‘increase in value over time and have (ideally) infinite life-spans’ (2017: 25). Thompson’s initial interest is in how an object can cross over from one category to the other, as they do in the case of ‘vintage’ cars, re-valued pieces of furniture, and works of art. The question precipitates a new third category for goods that are neither decreasing nor increasing in value but are of no value at all: rubbish.
Whilst at first glance Thompson appears to be discussing something that fits with normative ideas of waste, his ‘rubbish’ category is in fact quite specific. Although he explicitly describes the rubbish stage as denoting a value-less state, the examples he uses – which later move into the category of durables – never seem to attain the state of zero value. Stevengraphs, for example, steadily decreased in value throughout the first half of the twentieth century before reaching relatively astronomical prices from the 1960s onwards. Yet even at the Stevengraphs’ point of lowest value, Thompson quotes a source noting that there were still probably ‘a few discerning people quietly collecting them for their decorative charm’ (44).
Thompson’s rubbish category is restricted to a class of objects that still have owners, have depreciated in value, but have not been disposed of. This constitutes a restricted category of rubbish, excluding what most would think of as waste and the discarding practice that others would regard as the key moment when objects pass into a waste category. Drawing on Douglas’s assertion that ‘dirt is simply matter out of place’, Thompson is not particularly interested in the lowly objects that do not attract attention because they are widely regarded to be in the right place: the dustbin or landfill. His concern lies in radical value transfers as a source of social transformation.
Nevertheless, the aspiration to understand material flows and the creation and destruction of value in British society arguably laid the foundations for more recent social science studies into globalised flows of discards and their connection to domestic waste practices. This scholarship is interested in the question of value but not necessarily as the polar opposite of waste, with attention directed towards the political economy and government of waste, and how these are impacted by contemporary knowledge about waste and its effects. Perhaps the most ambitious attempt to theorise divergent state approaches to waste is Zsusza Gille’s (2007) idea of ‘waste regimes’. With this concept, Gille argues that the affordances of one kind of waste are used to understand, represent, and direct the treatment of other waste streams, sometimes to damaging or hazardous effect. This is neatly illustrated by the 1950s Hungarian state emphasis on collecting scrap metal. While metal can be easily stored, storing other wastes such as toxic chemicals in similar ways, ignoring their unique chemical properties, meant that often barrels rapidly corroded and leaked. Gille thus argues that rather than viewing the category of waste purely as a social construction, we need to account for the role of specific materialities and to consider both state and citizen responses. Here we see a focus on states, cultural representations, and the political economy of waste replacing the idea of unique ‘cultural’ approaches to waste.
Historical works (e.g. Strasser 1999, Zimring 2005, Thorsheim 2015) have shown the long lineage of domestic practices of material recovery and re-use. Recently attention has turned to the global nature of the recycling industry and how this links domestic practices to transnational flows of stuff. Thus, Catherine Alexander and Josh Reno’s collection, Economies of recycling (2012), mobilised economic anthropology and a focus on how people use, consume, and engage with objects (material culture studies) to destabilise conventional understandings of household and global economies. Contributors analysed the profoundly unequal global flows of waste materials – textiles, ships, electronics, uranium, medical discards – in terms of their location of production and recycling – concerns also taken up by The Waste of the World project and its subsequent publications. The collection also highlighted how various forms of waste labour and waste processing have been cast as redemptive, drawing on a Protestant-inflected language of salvation. Britt Halvorson’s (2012) ‘No Junk for Jesus’ chapter, for example, examines the flow of medical discards between Lutheran churches in the United States and Madagascar, where the sorting of waste from viable donation constitutes a form of religious service. One of the key benefits of this global approach was to highlight that, for all the focus on consumer and domestic recycling practices, household waste accounts for only a fraction of the waste stream.
Construction waste, for example, makes up a large percentage of urban waste streams and it has served as a useful lens through which to study wider questions of land speculation, urban development, and dispossession. Gastón Gordillo (2014) analyses how the rubble of different rural development schemes in northern Argentina, from Jesuit agricultural collectives to soy production, can provide clues to changing socio-economic forces. Across the world, Erik Harms’ (2016) study of two housing developments in Saigón is more concerned with the conversion of wastelands than with waste material per se. Yet a bridge can be found in Harms’ exploration of the ways in which existing productive uses of land (in his case, smallholder farming) are ignored whilst urban development is championed, through a dominant Vietnamese trope of ‘civilising the southern wasteland’. Gordillo and Harms’ theorisations thus mirror each other; the former emphasising the way that infrastructures are laid to waste to make room for emergent projects of accumulation and the latter, the possibilities for construction once territory has come to be perceived as wasteland. In both cases, it is not symbols, but the materiality of rubble, bricks, building plans, and maps that tell us something about societies and the utopias that transfigure and disfigure landscapes at distinct moments in time.
For Harms, waste is evoked in order to open up space for economic and political intervention and value creation through the construction of real estate. This is only one of a number of possible relations between waste and value. As Alexander and Sanchez (2018: 3) note, waste can be seen as the anti-thesis of value, lost value, the enabler of value, or simply another word for resource. Their 2018 volume on indeterminacy, waste, and value echoes the work of Thompson in that they introduce a third term – indeterminacy – to trouble the stubborn binary between waste and value. Rather than proceeding from an analytical definition of indeterminacy, they start from ethnographic examples to highlight different modes of indeterminacy for people and materials. They share with Douglas an interest in the people that fall through the cracks of classificatory systems, suggesting that such systems are by their very nature exclusionary and key to creating discarded populations. Simultaneously, their idea of indeterminacy challenges both Thompson’s scheme of distinct value positions (transient, rubbish, durable) and Douglas’ framework of single, unified cultural systems of order (2019: 15).
Materialist scholars have gone so far as to criticise Douglas’s for ignoring the qualities of dirt and its alleged dangers in the study of pollution, as part of an alleged ‘rubbish idealism’ (O’Brien 2002: 133). For this new generation of anthropologists, with eyes trained on waste’s materiality, its odours, and hazards as well as creative potentials, nothing could be further from their position. Economic-materialist analyses of waste in anthropology have tended to highlight how waste’s materiality influences its nature and appearance even if it does not determine it fully. They have also thought of new ways in which waste may be extracted from its classification and become re-valued.
Intersubjective and post-human
For symbolic-structuralist approaches, a fundamental question is why different things are considered waste in different cultures – and the answer given is their culturally-specific classificatory systems. Economic-materialists shift the question to how the dynamics of waste flows link domestic and global industrial scales, and answer it by examining these flows in a globalised schema of reproduced inequalities. A third thematic concern among anthropologists, which is also interested with the how, but often at different scales, is a focus on subjectivity and the kinds of relationships and identities that are created through associations with waste. For scholars such as Gay Hawkins (2006), the creation of subjectivities through engagements with waste is at once a profoundly ethical process and echoes actor network theory (ANT) in signalling that waste itself has agency; it both acts, and is acted upon. Household recycling, for example, is an everyday ethical act that becomes drummed into the body – embodied – through repetition and practice.
The role of waste and dirt in creating and sustaining oft-unequal subjectivities has a long history of study inside and outside anthropology. In colonial public health policies, for example, we find two interlinked processes: colonial subjects are often portrayed as dirty, backward, and thus in need of a mission civilisatrice, whilst at the same time the most oppressed people are often called upon to carry out the jobs seen as ritually and hygienically polluting, such as waste work. Race, waste, and power often come together to mark out such distinctions. In the American Philippines (Anderson 1995), as in British India, Australia (Bashford 2003), and elsewhere, colonial governments used public health measures such as vaccines, quarantine, and segregation to demarcate physical and racial boundaries and govern unruly populations. These are far from purely historical questions: consider the furore in early 2019 over a Fox News host’s comment, echoing similar statements made by Donald Trump, that mass migration made America ‘poorer, dirtier, and more divided’, an assertion he supported with images purporting to depict garbage and trash left behind by migrants at the US-Mexico border. Indeed, representations of the dirty colonised other have arguably been transferred onto the figure of the immigrant other (c.f. Thorleifsson 2017), although proletariat or lumpenproletariat populations have also often been the target of similar discourse and measures of bio-political governance.
‘Waste colonialism’ and its sister term ‘garbage imperialism’ are nowadays primarily used to describe instances or patterns of rich countries dumping their waste on poorer ones. This is to some degree limited by the Basel convention and a spectrum of injustice can be detected in such practices, which range from the export of recoverable, non-toxic recyclate to the dumping of contaminated materials. As Reno notes, ‘not only waste but also waste regimes have been exported and experimented with abroad through colonial and imperial formations’ (2015: 565). Max Liboiron likewise argues that ‘waste colonialism goes beyond the export of waste from colonial centres to… peripheries’ (2018). Relevant to our discussion of ‘rubbished’ subjects here is her point that dominant interpretative frameworks of hygiene and cleanliness are still imposed on peoples whose landscapes and means of subsistence have already been rubbished or enclosed. Waste-pickers and scavengers, for example, are often cited as exemplary polluted subjects, the discards of modernity, or as indexing global inequality (Reno 2009: 32).
Anthropologists have been able to get behind the headlines and assumptions about waste work through ethnographies of informal waste labour like Rosalind Fredericks (2018) on Dakar, Minh Nguyen (2018) on Vietnam, Kathleen Millar (2018) on Rio de Janeiro, Jamie Furniss (2017) on Cairo, and my own research on Montevideo (O’Hare 2018). In my work, waste-pickers in Uruguay proudly adopt the term ‘classifiers’ to signal the productive and environmentally important nature of their labour and overturn the stigma associated with their previous moniker, ‘rummagers’. Similarly, Furniss (2017) describes how Egyptian Christian minority waste-workers downplay both derogatory titles – such as the Zabaleen – and upper-class attempts to focus on the ‘environment’, emphasising instead their role as cleaners of the city. Nguyen (2018), meanwhile, tracks the complex networks and connections between city and village. In her account, Vietnamese waste traders opt to suffer and even perform stigma in the city in order to amass sufficient capital to build their homes and status in rural villages.
Millar’s work on Rio’s Gramacho landfill, the largest in South America until its closure in 2012, is a particularly sensitive portrayal of waste-pickers in their wider social world, far from the kind of abject, desperate figures so frequently found in media accounts. She shares with Reno’s (2016) ethnography of an industrial Michigan landfill an attempt to highlight the way that waste work helps to constitute desirable subjectivities, from masculine identities of repair and manual labour to the freedoms of autonomous work outside of waged work. As such, Millar argues that academics should be careful when echoing reactionary commentators by referring to people as surplus or waste (cf. Baumann 2003), even if we simultaneously voice a critique of injustice.
While Millar attends to the materiality and plasticity of waste, her focus remains on the human subject. Other approaches, however, also accord agency – and sometimes subjectivity – to waste materials and the non-human animals that co-produce them. Gregson et al. (2010), for example, identify an economically performative aspect of asbestos, as its presence intervenes in ship-breaking work in the EU. Undetected asbestos slows down the work of waste removal and complicates contracts given that these are based on asbestos removal estimates gleaned from initial surveys. Hird (2013) meanwhile, emphasises how the inhuman and nonhuman life forms found within waste (e.g. leachate and bacteria) and their physically, biologically, and chemically determined time-frames complicate human technocratic attempts to measure, know, and control waste. The engineering time of landfills, for example, is only a hundred years, whereas the thousands of diverse materials assembled there – chemicals, bacteria, organic matter – will continue to interact and have unpredictable effects long beyond this time period. As Gille (2013) has argued in response, however, the fact that we cannot fully know waste and its long-term effects can very often be used against the communities that make claims about contamination. In the study of waste therefore, there are times when it is responsible to emphasise relative certainty over doubt.
Reno (2014) has also drawn attention to the ways in which waste can be considered a ‘sign of life’ rather than ‘matter out of place’. Scat (animal faeces) resists both a symbolic interpretative framework and being preconceived as a distinctly human problem. Encountered by human and non-human animals when hunting or mapping out patterns of animal behaviour, scat indicates life rather than life-threatening contamination. This theorization of waste (alongside Reno 2018), is post-human, as it dislodges the human subject from its primary position, relegating it to just another animal involved in cross-species interactions. In this work, not only scat but indeed waste more broadly can be thought about bio-semiotically as the point of encounter between the many species that both create, and are created by it.
If forms of ‘scat’ have been around for millions of years, more recent forms of waste material also shape human life rather than being simple reflections of cultures. The continued work of Gay Hawkins (2006, 2015, 2018) has brought some of these instances to light. In her most recent book, she argues that the plastic water bottle was revolutionary in shifting people’s perception of plastic away from ideas of durability towards ideas of disposability and single-use: disposability highlights how things design us. For profitable ‘throw-away’ economies to succeed, people’s habits and customs had to be changed, creating the consumer who only in recent years has begun to rediscover forms of re-use and recycling.
What kinds of subjects might be needed for responsible engagements with waste in the twenty-first century and what can social scientists contribute towards this debate? One potential ethical position is that advocated by Jane Bennett (2010), who suggests a re-enchantment with the power of agentive things, waste included. As others have noted, this invitation comes up against the hard reality of certain materials that simply aren’t nice for humans to become enchanted with (from asbestos to nuclear waste). Yet perhaps we can learn from the enchantment and pleasure that waste-pickers and dumpster divers experience both from rummaging in the trash and from carrying out socially responsible acts of recovery and cleaning (c.f. Millar 2018, Barnard 2016). More broadly, what the mutual constitution of subjects and their wastes exemplifies is that in a world of rapidly evolving materials, many of which become waste, human beings change our actions, categories, and indeed ourselves according to our responses to these materials. More circular models of production and consumption are certainly part of this story. Yet in redrawing the line of disposal as a virtuous circle, anthropologists can also bring attention to the ways that subjects who have built positive identities and livelihoods out of waste work might be left out the loop.
Waste does not exist in the singular, and indeed it can be the combining of substances and things in particular spaces that leads to their classification as waste, a point highlighted in the early symbolic-structuralist approaches to waste that has continued relevance today. Purity in waste management is important: muddling materials in composite packaging and baled recyclate makes things very difficult to recycle, leading to landfilling, and accusations of ‘waste colonialism’. The technical dynamics of transnational waste chains might seem far from relativist understandings of what constitutes waste, but cultural understandings of hygiene and cleanliness continue to play an important role. To give just one example, David Evans (2014) has explored how residents’ ideas that food waste caddies are ‘out of place’ on kitchen counters play a role in limiting the recycling of food waste in the UK.
Similarly, there is no single anthropology of waste, and although the different approaches sketched out here imply a chronological arc, residues of earlier orientations can still be found in the present, often in unexpected places. While anthropologists of waste might still be interested in menstrual pollution and taboo, they increasingly deal with global flows of problematic, indeterminate matter that challenge binaries along the sacred-profane or waste-value axes. Categories such as ‘indeterminate’ or ‘rubbish’ indicate some of the mediating roles that waste plays between the creation and destruction of value, as do ethnographies that highlight how people situate themselves pragmatically with regard to ascriptions of waste. Societal stigmas of being associated with waste still matter, but anthropologists have shown how these can be manipulated and disguised, from respected waste traders in Vietnam, to medical discards that are repackaged as benevolent donations as they travel from the Unites States to Madagascar. By getting its hands dirty, the anthropology of waste contributes to an epistemology of the ever-more complex and voluminous materials that humans and non-humans produce, consume, discard, and digest in our Anthropocenic present.
