Globally, scrap metal is vital to the steel industry, accounting for roughly a third of metallic raw materials used in steel production, according to the Organisation for Economic Cooperation and Development.
Across Zimbabwe’s capital city, Harare, thousands live off scrap metal. The city generates over 1,000 tons of waste every day, most of which is uncollected, leading to civic problems.
Once-pristine neighborhoods have become polluted eyesores. Recently, the city council partnered with a green energy waste management company to improve collection amid contested accusations of corruption. But for now, informal pickers remain indispensable. Quietly, the collectors are helping to sustain a cleaner environment and combat climate change.
The pickers play a crucial role by salvaging non-biodegradable metals that would otherwise pollute the city. Their work also supports local steel production and contributes to reducing carbon emissions by recycling scrap metal.
Globally, scrap metal is vital to the steel industry, accounting for roughly a third of metallic raw materials used in steel production, according to the Organization for Economic Cooperation and Development. With growing concerns over the environmental impact of mining and rising interest in circular economies, demand for recycled materials is increasing.
The steel industry contributes nearly 8% of global energy sector carbon dioxide emissions, according to the OECD. Many steelmakers cannot afford to invest in new, cleaner technologies. That makes scrap recycling a critical — and accessible — alternative. There are no official statistics on the number of metal collectors in Zimbabwe.

But the job comes with some challenges. The collectors are often faced with dangerous and disgusting sights. They are also upfront about health hazards and are mostly unprotected while sifting through debris.
