Africa's Cities Grapple With Escalating Waste Crisis
Rapid urbanization and insufficient infrastructure are overwhelming waste management systems across the continent, leading to environmental and health hazards.
Johannesburg is confronting a severe waste crisis, characterized by unreliable collection services, dwindling landfill capacity, and a surge in illegal dumping, mirroring a broader challenge across Africa. In the city's industrial suburb of Kya Sands, a mountain of illegally dumped trash has grown substantially since 2021, now engulfing a road and emitting constant fumes.
This burgeoning dumpsite emerged after the municipal landfill reached its capacity and closed in 2010. Now, waste continues to spread across the valley, with trucks regularly adding to the accumulation and smoke rising from the piles.
Rapidly growing African cities such as Lagos, Dakar, and Accra are generating waste at a pace that outstrips the capacity of many municipalities to collect, recycle, or safely dispose of it. Projections indicate that Africa's urban population will double to 1.4 billion by 2050, according to a joint report from the OECD, African Development Bank, Cities Alliance, and United Cities and Local Governments of Africa. The United Nations Environment Program estimates that over 90% of waste generated in Africa is disposed of in uncontrolled dumpsites and landfills, often involving open burning. The World Bank forecasts a 124% increase in waste generation in sub-Saharan Africa by 2050, the highest rate globally.
In Johannesburg's densely populated Alexandra township, residents navigate sidewalks littered with household waste, plastic, food scraps, and construction debris, while livestock forage through the refuse. Concerns are mounting over the health implications for children living in close proximity to these conditions.
The city's waste management company, Pikitup, has identified over 2,000 illegal dumping hotspots and has allocated 115 million rand ($6.4 million) for the 2025/26 fiscal year to address the issue. However, some residents report garbage going uncollected for up to four weeks, with disruptions attributed to labor disputes, financial constraints, and an aging fleet, according to the Johannesburg Crisis Alliance.
The unreliability of official waste collection services has fueled demand for informal waste haulers. While these services offer a solution for residents, some informal collectors bypass legal disposal requirements, including registration and landfill fees, leading to illegal dumping in areas like Kya Sands.
Illegal dump sites also contribute to air, soil, and water pollution through the burning of trash to create more space. This practice exposes nearby communities to toxic substances, with residents reporting difficulty breathing due to the fumes, particularly at night. The poor air quality is also impacting local ecosystems, such as beekeeping operations.
Dr. Suzan Oelofse, a principal scientist at South Africa's Council for Scientific and Industrial Research (CSIR), highlighted that poorly managed waste attracts vermin and can clog stormwater drains, increasing flood risks. She noted that waste generation consistently outpaces investment in new waste management infrastructure, leaving cities like Johannesburg heavily reliant on aging landfills while recycling and composting efforts struggle to gain momentum.
South Africa's draft National Waste Management Strategy indicates that landfill space is depleting at an unsustainable rate. In Johannesburg, only two of the city's four municipal landfills currently accept general waste, and a recent CSIR study suggests that these remaining landfills have less than a year of disposal capacity left on average.
Solutions to expand landfill capacity are hampered by the scarcity of suitable land and stringent environmental regulations. Experts estimate that up to 80% of Johannesburg's waste could be diverted from landfills through increased recycling and organic waste treatment, provided households and businesses implement waste separation at the source. Pikitup is actively promoting this initiative and plans to enhance recycling infrastructure and collaborate with waste reclaimers. Support for waste pickers, including access to resources and protective equipment, is also seen as crucial for improving the diversion of recyclable materials from landfills.
