Livelihoods in Waste Management: The Role of Formal and Informal Sectors

Every day, millions of people around the world wake up before dawn, grab their carts or bags, and head out to collect what others have discarded. These are the informal waste workers-waste pickers, rag collectors, and scrap dealers-who form the backbone of recycling systems in developing countries. While they often work in the shadows, unrecognized and undervalued, up to 20 million people worldwide rely on waste collection as their primary livelihood. Their work doesn’t just sustain their families-it sustains the planet.

The hidden heroes of waste management 🔗

In many developing nations, formal waste collection systems are either absent or inadequate. This gap has given rise to a vast informal workforce that operates outside official channels but delivers remarkable results. Approximately 59 percent of all plastic material collected for recycling globally is handled by informal waste workers. In 2016 alone, they collected 27 million metric tonnes of plastic waste, preventing it from polluting landfills and oceans.

These workers include street pickers who scavenge through public bins, door-to-door collectors who provide household services, and dump scavengers who sort through landfills. Despite their different methods, they share a common purpose: extracting value from waste while keeping cities cleaner. In Bangalore, 15 percent of municipal waste is collected informally each day, while in Cairo, informal collectors handle between 30 and 40 percent of all waste-amounting to 900 tonnes daily.

Operating beyond municipal reach 🔗

One of the greatest strengths of informal waste workers is their ability to serve areas that formal systems cannot or will not reach. In neighborhoods lacking official collection services, informal workers provide door-to-door pickup, often using handcarts, bicycles, or small motorized vehicles. They know their communities intimately, understanding collection schedules, household patterns, and the specific types of waste generated in different areas.

This localized knowledge-what we might call tacit knowledge-enables them to operate efficiently even without formal training or technology. They can identify valuable materials at a glance, sort waste with practiced hands, and navigate informal networks of buyers and recyclers. In India alone, waste pickers represent 1 percent of employment, which translates to 2.2 million workers contributing to the recycling economy.

Following the waste value chain 🔗

Understanding how waste transforms from household discard to recycled material requires mapping the entire value chain. This journey involves multiple stakeholders, each playing a distinct role in extracting value from what others consider worthless.

From generation to collection 🔗

The waste value chain begins at generation points-households, commercial establishments, industries, and public spaces. Here, the first critical decision occurs: will waste be separated at source or mixed together? In most developing countries, source separation remains uncommon, which means informal workers must sort through mixed waste to identify recyclables.

Informal collectors gather materials through various methods. Street pickers move through neighborhoods on regular routes, checking bins and collecting discarded items. Some collectors announce their presence with distinctive calls or use loudspeakers to alert residents. Others negotiate regular pickup arrangements with households, exchanging collection services for access to recyclable materials. Many residents, particularly in South Asian countries, even receive small payments or in-kind benefits for their segregated recyclables.

The sorting and intermediary network 🔗

Once collected, materials enter a complex network of intermediaries. The waste value chain spans from suppliers of suppliers to buyers of buyers, with each link adding value through sorting, cleaning, and consolidation. Small scrap dealers, known locally as kabariyas in South Asia, serve as the first point of sale for many collectors. These dealers purchase materials by weight, providing immediate cash that sustains picker livelihoods.

From small dealers, materials move to larger wholesalers who aggregate sufficient quantities to supply recycling plants and manufacturers. Each transaction involves negotiation, with prices fluctuating based on material quality, market demand, and global commodity prices. This decentralized system, while sometimes exploitative, creates employment opportunities at multiple levels and responds dynamically to market signals.

Treatment and recycling 🔗

The final stage involves processing centers and recycling plants where materials are transformed into secondary raw materials. Plastics are melted and reformed, metals are smelted, paper is pulped, and glass is crushed and remelted. These facilities range from small-scale cottage industries to large mechanized plants. The waste management and recycling industry employs an estimated 6.9 million people globally, though this figure significantly underestimates informal sector participation.

Formal versus informal systems 🔗

The contrast between formal and informal waste management reveals different strengths, weaknesses, and operational philosophies. Understanding these differences is essential for developing integrated approaches that leverage the best of both systems.

Formal systems in developed countries 🔗

Formal waste management systems, common in developed nations, are characterized by municipal contracts, mechanized collection, and regulated processing facilities. Trucks follow predetermined routes on fixed schedules, collecting waste from standardized bins. Sorting occurs at centralized material recovery facilities using conveyor belts, magnets, and optical sensors. Workers receive regular wages, safety equipment, and health insurance.

These systems excel at systematic coverage and maintaining public health standards. However, they require substantial infrastructure investment and ongoing operational funding. In many developing countries, establishing formal waste management across India via public-private partnerships would require USD 5 billion annually-if it could be implemented at all.

Informal systems: resourceful but precarious 🔗

Informal waste management operates with minimal infrastructure but maximum flexibility. Workers respond immediately to price signals, shifting collection priorities based on market demand. They reach areas inaccessible to large trucks, collect materials that formal systems ignore, and achieve high recovery rates through labor-intensive sorting.

However, these advantages come at tremendous personal cost. In half of 49 developing countries with available data, workers in waste management are more likely to be in informal employment compared to other industries. They lack social protection, work excessive hours, face health hazards, and experience social stigma. Their earnings are low and unstable, vulnerable to market fluctuations and exploitation by intermediaries.

Challenges faced by informal workers 🔗

Despite their essential contributions, informal waste workers endure deplorable conditions. They handle waste with bare hands, exposing themselves to sharp objects, toxic substances, and biological hazards. Many work in extreme weather without protective equipment. Women workers often face additional challenges, including harassment and lower earnings compared to male counterparts.

Social marginalization compounds these physical hardships. Waste work carries stigma in many societies, particularly in cultures where handling waste is considered taboo. Waste pickers may avoid researchers, fearing information will be passed to officials, which makes even documenting their contributions difficult. They exist in a legal gray zone-neither fully recognized nor explicitly banned-vulnerable to harassment by authorities and exploitation by middlemen.

Bridging formal and informal approaches 🔗

The future of waste management lies not in choosing between formal and informal systems but in integrating their complementary strengths. Some cities have pioneered inclusive models that recognize informal workers as legitimate stakeholders.

In Belo Horizonte, Brazil, waste picker cooperatives receive municipal support including infrastructure, subsidies, and training. These organized workers earn higher incomes than other informal sector workers while providing cost-effective recycling services to the city. Colombia’s Constitutional Court has issued rulings requiring municipalities to integrate waste pickers into sanitation planning, establishing their legal status as service providers.

However, formal sector stakeholders often view informal collectors as unhygienic, backward, and not aligned with modern waste management systems. Overcoming these biases requires changing perceptions, developing inclusive policies, and creating regulatory frameworks that support rather than exclude informal workers. When policies privatize waste collection without considering informal workers’ livelihoods, the results can be devastating-stripping people of their only income source while overloading formal systems.

Creating sustainable livelihoods 🔗

Effective integration must address both the efficiency of waste management and the dignity of waste workers. This includes providing legal recognition, access to protective equipment, fair payment for environmental services, and pathways to formalization that don’t destroy livelihoods. It means acknowledging that while mechanization may increase efficiency, it also reduces employment opportunities in countries where job creation is critical.

Successful integration also requires recognizing informal workers’ entrepreneurial spirit and local expertise. Rather than viewing them as problems to be solved, progressive policies treat them as partners in achieving circular economy goals. The informal sector requires less infrastructure, is highly responsive to economic signals, and is very flexible-qualities that make it economically sustainable and socially inclusive when properly supported.

What do you think? How can your community better recognize and support the informal workers who keep our streets clean and materials in circulation? What role should government policy play in protecting waste workers while advancing environmental goals?
