A waste picker also known as waste collector or garbage collector is a person who salvages reusable or recyclable materials thrown away by others to sell or for personal consumption. There are millions of waste pickers worldwide, predominantly in developing countries, but increasingly in post-industrial countries as well. Various forms of waste picking have been practiced since antiquity, but modern traditions of waste picking took root during industrialization in the nineteenth century. Over the past half-century, waste picking has expanded vastly in the developing world due to urbanization, toxic colonialism and the global waste trade. Many cities only provide solid waste collection.
Terminology Many terms are used to refer to people who salvage recyclables from the waste stream for sale or personal consumption. In English, these terms include rag picker, reclaimer, informal resource recoverer, litter picker, recycler, poacher, salvager, scavenger, and waste picker; in Spanish cartonero, chatarrero, pepenador, clasificador, minador and reciclador; and in Portuguese catador de materiais recicláveis. A more contemporary term, focusing on the outcome of the professional activity, is "informal sector recycling". However, the word "informal" can be partly misleading, because in practice a continuum between total informality and proper organization in taxed registered formal activities may be encountered. In 2008, participants of the First World Conference of Waste Pickers chose the term "waste picker" for English usage to facilitate global communication. The term "scavenger" is also commonly used, but many waste pickers find it demeaning due to the implied comparison with animals. A waste picker is different from a waste collector because the waste collected by the latter may be destined for a landfill or incinerator, not necessarily for a recycling facility. "Dumpster diving" generally refers to the practice of anti-consumer and freegan activists who reclaim items such as food and clothes from the waste stream as a form of protest against consumer culture. "Waste picking" generally refers to activity motivated purely by economic need.
Prevalence and demographics There is little reliable data about the number and demographics of waste pickers worldwide. Most academic research on waste pickers is qualitative rather than quantitative. Systematic large-scale data collection is difficult due to the profession's informal nature, porous borders, seasonally fluctuating workforce, and widely dispersed and mobile worksites. Also, many researchers are reluctant to produce quantitative data out of fear that it might be used to justify crackdowns on waste picking by authorities. Thus, the large-scale estimates that do exist are mainly extrapolations based on very small original research samples. In his book, "The World's Scavengers" (2007), Martin Medina provides a methodological guide to researching waste picking. In 1988, the World Bank estimated that 1–2% of the global population subsists by waste picking. A 2010 study estimates that there are 1.5 million waste pickers in India alone. Brazil, the country that collects the most robust official statistics on waste pickers, estimates that nearly a quarter million of its citizens engage in waste picking. Waste picker incomes vary vastly by location, form of work, and gender. Some waste pickers live in extreme poverty, but many others earn multiple times their country's minimum wage. Recent studies indicate that waste pickers in Belgrade, Serbia, earn approximately US$3 per day, while waste pickers in Cambodia typically earn $1 per day. Official statistics in Brazil indicate that men earn more than women, regardless of age. Approximately two-thirds of Brazil's waste pickers are men overall, but this proportion jumps to 98% in high income waste picker groups (those earning between 3–4 times the minimum wage). No women were found in the highest income groups (those earning over 10 times the minimum wage).
Causes
In developing countries
Over the past half century, in-country migration and increased fertility rates have caused the population of cities in the developing world to mushroom. The global population of urban dwellers is expected to double between 1987 and 2015, with 90% of this growth occurring in developing countries. Much of the new population has settled in urban slums and squatter settlements, which have expanded rapidly with no central planning. The United Nations Habitat Report found that nearly one billion people worldwide live in slums, about a third of the world's urban dwellers. The rapid urbanization greatly increased the demand for informal waste collecting services, as cities lacked the infrastructure and resources to collect the totality of wastes generated by their inhabitants. Despite spending 30–50% of operation budgets on waste management, developing world cities today collect only 50–80% of refuse generated by inhabitants. Residents and businesses often resort to burning garbage or disposing of it in streets, rivers, vacant lots, and open dumps. This is a source of air, land, and water pollution that threatens human health and the environment. Informal waste collectors help mitigate this harm by collecting recyclable materials by foot or in pushcarts, tricycles, donkey carts, horse carts, and pickup trucks. On the supply side, urbanization has facilitated the expansion of waste picking by creating a large pool of unemployed and underemployed residents with few alternative means of earning a livelihood. Known as "the one industry that is always hiring", waste picking provides a cushion for many who lose their jobs during times of war, crisis, and economic downturn in countries that do not have welfare systems. It is also one of the few work opportunities available to people who lack formal education or job experience.
