A job with contradictions: environmental stewards and exploited workers of the informal sector

Solid waste is an environmental concern throughout the world. The work of handling this waste involves diverse hazards, and is the focus of many prevention activities.1–4 In Brazil, as elsewhere, the increasing consumption of goods has generated a huge volume of waste, raising questions about the impacts of inadequate collection and traditional waste disposal technologies on the health of workers, the public, and the environment.5–7 Recycling presents many benefits, but like any new productive enterprise, its effects on those who do the physical labour must be weighed when assessing its full societal and environmental impact.

High unemployment, combined with proliferating amounts of solid waste, and a growing global market for recycled materials, have created the conditions for the rapid expansion of the work of collecting and selling trash. In Brazilian cities today, ragpickers (catadores de lixo in Portuguese) collect, separate, classify, and sell all types of recyclable materials. It is not known how many people work as ragpickers in Brazil, but a recent study estimated 500 000 in 2003, including adults and children (Forum Lixo e Cidadania, 2003). The majority of these workers rely solely or primarily on ragpicking for their livelihood, and have incomes less than twice the level defined by the Brazilian government as a minimum living wage, which comes to about US$173. They often live near dumps or in the low income areas of cities, and collect recyclable materials and food at dumpsites, riverbanks, street corners, and residential areas (Fórum Nacional Lixo e Cidadania, 2003). This relatively new and apparently growing labour force is responsible for handling a large share of all Brazilian recycled materials. Their work, entirely informal and lacking in almost any controls, employment benefits, or regulations, has led Brazil to become one of the largest recyclers in the world, in particular, of aluminium.7,8 They help cities reduce waste in landfills, support recycling companies, and feed their families through their work.7,8

The purpose of this article is to describe the working conditions and health hazards for a sample of ragpickers in one Brazilian city, highlighting their work and living conditions.

METHODS

We conducted a cross-sectional study of ragpickers older than 17 years in Pelotas, a city of 320 000 in southern Brazil, in 2004. For comparison, we identified a sample of non-ragpickers who were residents of the same neighbourhoods, and of similar gender, age, and years of schooling. Data were collected through a survey that included questions on occupational, sociodemographic, behavioural, and health factors. Because ragpickers and non-ragpickers in our sample both came from poor neighbourhoods, it was also useful to compare their physical activities and symptoms to a sample of the entire adult population of the city. To accomplish this, we were able to take advantage of a recent survey based on a stratified random sample of the entire city population (n = 3182), which used many of the same survey items.9

This study was approved by the Ethics Committee of the Medical School of the Federal University of Pelotas.

RESULTS

The ragpickers’ survey involved 990 subjects, of whom 455 were ragpickers and 535 non-ragpickers (table 1). Because our survey involved household interviews, the very poorest ragpickers, living entirely on the street, were not studied. Despite this, our ragpickers had considerably poorer living conditions than their neighbours with other occupations. For example, most (54%) of ragpickers’ houses were of wood, metal, or other poor materials, compared to only 24% of their neighbours’ houses. Three times as many ragpickers as non-ragpickers had no running water (15% versus 5%); there was a similar difference for lack of electricity (11% versus 5%). Eighteen per cent of the ragpickers had no toilet in their house, compared to only 3% of their neighbours.

Table 1

 Sociodemographic characteristics of ragpickers, non-ragpickers, and a sample of the general population of Pelotas

Almost half (47%) of the ragpickers were non-white, compared to 32% of non-ragpickers, and only 15% of the Pelotas general population. Although we attempted to match non-ragpickers to ragpickers to within one year of schooling, the differences were so marked that our samples retained some striking differences in education. Fully 22% of ragpickers had not completed a single year of schooling, while only 12% of the non-ragpicker sample had no schooling. In the general population sample, only 1% reported less than one year of schooling (table 1).

The average monthly income of ragpickers was about US$81.64 (SD $62.76), while non-ragpickers reported more than twice the average income ($188.53, SD $170.71). In Brazil, incomes are often compared in multiples of the government’s minimum wage (approximately US$86.67 per month). Ninety four per cent of ragpickers reported income less than twice the minimum wage, compared to 62% of non-ragpickers and 39% of the population of Pelotas (table 1).

The average age for ragpickers to start working in this occupation was 32.5 years (SD 13.6 years), and they reported a median time on the job of three years. Most ragpickers (57%) are between 18 and 40 years old. These data suggest that many have taken up this work relatively recently. The ragpickers worked an average of 6 hours/day, which is less than the average reported work day of their non-ragpickers neighbours (8 hours/day).

Many city governments have begun to encourage the formation of cooperatives of ragpickers, to try to improve their working conditions.8 In Pelotas, only 6.8% of the ragpickers surveyed belonged to a cooperative, however.

Ragpickers’ work

The work process of ragpickers can be summarised in three phases: collection, separation, and sale of materials. The most commonly collected wastes, in decreasing order, are: plastics, paper/cardboard, aluminium, and iron. These materials are collected from the streets and doorways of households and businesses, and brought to some location where they can be separated. Separation is often performed in or just outside of the ragpickers’ houses, or on abandoned land along roadways, rivers, and old industrial sites (fig 1). This process is not regulated or licensed. Personal protective equipment is rarely worn; only 22% reported wearing gloves, 16% boots, and 1% facemasks. The most common equipment used to carry materials is the horse cart, followed by the pushcart (fig 2). Occasionally bicycles may be used or the ragpickers carry their loads themselves.

 Houses of ragpickers are often of very poor condition. They bring garbage back to the house to separate it, and there are often piles of non-recyclable waste dumped nearby.

The majority of ragpickers (86%) perform the most labour intensive separation of materials (removing copper wire from appliances for example) in their own homes; they dispose of whatever they cannot sell by dumping it in regular trash bins (56%) or burning it (30%). This process is performed manually, without the use of any tools, and often involves the whole family, including children. The ragpickers select edible food for their own consumption (fruits, produce, canned vegetables) from organic wastes collected.

Recyclable materials are transported from the ragpickers’ households to local “middle man” businesses that purchase recycled products (sucateiros in Portuguese) (fig 3). The ragpickers bring their collections to these businesses for weighing; and they are paid directly in cash, on the basis of the current market rate. Sometimes, they may be paid in food products in addition to cash.

Ragpickers’ hazards

Ergonomic hazards faced by ragpickers include walking long distances on foot,6 often pulling heavy carts and in awkward positions as they collect and separate waste. Most (91%) reported frequent repetitive motion, and nearly as many (84%) reported frequently carrying heavy (>10 kg) loads. Their frequent repetitive motion seems to be a defining characteristic, as it was reported 40% more often in ragpickers than non-ragpickers (prevalence ratio (PR) 1.4, 95% confidence interval (CI) 1.3 to 1.5). Fifty four per cent of ragpickers also reported frequent whole body vibration—probably often from their carts bouncing over city streets (fig 4).

Chemical hazards result from the hazardous substances found in municipal solid wastes, which ragpickers may inadvertently come into contact with. The most common are: car and regular batteries, oils and greases, insecticides/herbicides, solvents, paints, cleaning products, cosmetics, drugs, and aerosol containers under pressure.10 A significant portion of the wastes is classified as dangerous and can be harmful to human health and the environment.11 Ragpickers in Pelotas reported a high prevalence of contact with many of those products, and we found significant differences in these exposures compared to their non-ragpicker neighbours (fig 5).

 Prevalence of physical, chemical, and biological exposures among ragpickers and non-ragpickers.

Biological hazards reported by ragpickers in our survey included bandages, disposable diapers, toilet paper, sanitary napkins, disposable needles or syringes, and condoms. In addition, wastes from small clinics, pharmacies, and labs, and even hospital wastes, may also be found mixed with residential trash and carrying microorganisms responsible for more serious diseases.6,12 About a quarter (27%) of the ragpickers reported having contact with hospital wastes such as needles, syringes, and gauze, among other wastes (fig 5).

Safety hazards include risks from working amid heavy traffic, as trash collection schedules often coincide with intense traffic hours. When combined with poor compliance with traffic laws, high workload, and fast pace of work, there is a substantial risk of ragpickers being hit by traffic. Some of the most common injuries to workers who handle solid wastes are cuts and punctures by glass, cans, and sharp objects. Many of these injuries are caused by inadequate storage of trash.3,6

Psychosocial hazards result from the long and irregular workdays of this population, often including night work.13 In addition, the daily struggle for survival, the uncertainty about the future, the lack of prospects for a better life, low wages, and job discrimination all can have negative impacts on their mental health. About 50% of the ragpickers interviewed felt discriminated against by society. In contrast, 14% of their non-ragpicker neighbours reported feeling this way.

Job related injuries

The reported prevalence of low back pain in the 12 months prior to survey was similar among ragpickers and their non-ragpicker neighbours (49.2% versus 47.5%), but well above the prevalence found in the general population (35.1%). The prevalence of pain in the lower extremities (upper leg, knee, lower leg, and ankle) was higher in ragpickers than in non-ragpickers (45.1% versus 38.3%, p = 0.03). In contrast, there was no difference in the prevalence of upper extremity (neck, shoulder, elbow, wrist) pain in these two groups. We did not assess the latter two outcomes in the population of Pelotas.

Eighty per cent of ragpickers believed they could get injured on the job, and 71% believed their job was dangerous. Twenty per cent reported having had a work related accident the previous year. The most common injuries among those who had a workplace injury were cuts (59%), scrapes (15%), hits/contusions (10%), and punctures (9%). The most affected body parts were the hands (50%), lower extremities (20%), and feet (8%).

CONCLUSIONS

A recent World at Work article in this journal described refuse collectors in the United States and Europe.4 It would be hard to conceive of a more striking contrast in working conditions within a single occupation than is provided by a comparison of the Dutch and Brazilian workers described in these two articles. To begin to address the dire conditions under which ragpickers labour, it is perhaps most important to note that they are informal workers, entirely lacking in even the minimum guarantees found in regulated jobs. There are also formal jobs in refuse collection in Brazil2,3 and while these workers may face somewhat greater risks than their Dutch colleagues, they are considerably better off than the ragpickers.

The recycling “system” in Brazil contains complicated contradictions. From an environmental management perspective, ragpickers serve a very useful function to society, and regulations that inadvertently discouraged this work would mean even greater suffering for the population, as well as a bigger waste disposal problem. Ragpickers are discriminated against for the work that they do, and yet they play a very relevant public health role.14 There are some promising efforts in a number of Brazilian cities to promote cooperatives of ragpickers, as a way to improve their lives and provide them certain limited benefits.8,15 Some cities, for example, have provided the cooperatives with warehouses and trucks, the former to improve the collection and sorting work, and the latter so that they can get a fairer price for their materials by having the ability to sell directly to recycling industries instead of the local middle man.

Ragpickers should receive education on how to properly handle and dispose of wastes, as well as on the full range of health and safety issues. They should have access to personal protective equipment, materials handling devices, and safe means of transport. Our survey did not include children, and yet we observed many children engaged in recycling work that is clearly too dangerous for them. Improving the economic prospects of their parents is probably an important way to eliminate this unacceptable form of child labour.

The ultimate goal of the cooperative movement and other government sponsored or assisted programmes is to gradually introduce formal labour markets into the recycling sector. Only then will this important work be recognised and respected. Improving the working conditions of Brazilian ragpickers will require coordinated actions between civil society and governments to restore their social value and human dignity.
