Africa’s rapidly growing cities are facing a mounting waste problem as rubbish piles up faster than many municipalities can collect, recycle or safely dispose of it.
The Africa urban waste crisis is particularly visible in Johannesburg, where illegal dumpsites have expanded across communities and landfill space is rapidly shrinking.
In Kya Sands, an industrial suburb of Johannesburg, illegally dumped rubbish has formed a huge mound that now blocks part of a road.
Municipal councillor Devon Steenkamp said the pile was small when he took office in 2021. Since then, it has grown into a large mountain of waste, with residents also dealing with constant fumes.
Johannesburg Shows the Scale of the Waste Problem
The Kya Sands dumping site grew after a nearby municipal landfill reached capacity and closed in 2010.
Since then, rubbish has spread across the surrounding area. Smoke often rises from burning waste, while trucks continue to bring more material to the site.
The problem extends beyond Kya Sands.
In Alexandra township, residents face streets and sidewalks covered with plastic, food waste and construction debris. Pikitup, Johannesburg’s municipal waste company, has identified more than 2,000 illegal dumping hotspots across the city.
Some residents say their rubbish has remained uncollected for weeks.
As a result, informal waste haulers have become more common. However, high landfill fees and registration requirements can encourage some operators to dump waste illegally instead.
Africa’s Cities Are Growing Rapidly
Johannesburg’s struggle reflects a much wider problem.
Cities such as Lagos, Dakar and Accra are expanding quickly. At the same time, their waste systems often fail to keep pace with population growth and rising consumption.
Africa’s urban population is expected to reach about 1.4 billion by 2050, according to a joint report from international and African development organizations.
Meanwhile, the United Nations Environment Programme estimates that more than 90% of Africa’s waste ends up in uncontrolled dumpsites and landfills, often alongside open burning.
The World Bank has also projected a 124% increase in waste generation in sub-Saharan Africa by 2050 under its long-term outlook.
Therefore, the challenge is not simply about collecting rubbish. Cities also need enough land, infrastructure and funding to process the waste they generate.
Illegal Dumping Creates Health and Environmental Risks
Poor waste management can affect communities in several ways.
Open burning releases pollutants into the air. Meanwhile, waste can contaminate soil and water when authorities cannot control dumping sites.
Residents living near Johannesburg’s informal dumpsites have reported concerns about smoke and poor air quality.
Experts also warn that poorly managed waste can attract pests and block stormwater drainage systems. That can increase flooding risks during heavy rainfall.
The problem can also affect local businesses.
Bryce McCall, who runs a stable and beekeeping business near one dumpsite, said his operation has lost customers and horses as the waste problem has grown.
Johannesburg Is Running Out of Landfill Space
The shortage of disposal space makes the situation even more urgent.
South Africa’s draft National Waste Management Strategy warns that landfill capacity is declining at an unsustainable rate.
Johannesburg has four municipal landfills, but only two still accept general waste, according to the AP report.
A recent study by South Africa’s Council for Scientific and Industrial Research found that the city’s remaining landfills had, on average, less than a year of disposal capacity.
That leaves officials with limited options.
Building new landfills requires suitable land. However, land is increasingly difficult to secure, while environmental regulations also impose strict requirements.
Recycling Could Reduce Pressure
Experts say cities can reduce the pressure by keeping more waste out of landfills.
Suzan Oelofse of the Council for Scientific and Industrial Research estimates that Johannesburg could divert as much as 80% of its waste through recycling and treatment of organic material if households and businesses separated waste at the source.
Pikitup is also promoting waste separation and plans to expand recycling infrastructure.
Waste reclaimers already play an important role by recovering recyclable materials before they reach landfills.
However, workers say they need better access to collection points, protective equipment, storage facilities and community buy-back centres.
Waste Separation Could Help African Cities
Separating waste at its source could make recycling more effective.
Households could keep food and other organic waste separate from plastics, paper, glass and metals. Businesses could follow similar systems.
That approach could reduce the amount of material sent to landfills.
It could also create more opportunities for recycling businesses and informal waste workers.
However, successful waste separation requires reliable collection services. Without regular pickups and proper facilities, residents may have little incentive to separate their rubbish.
A Growing Challenge for Major African Cities
The Africa urban waste crisis is becoming harder to ignore as cities expand and landfill space disappears.
Johannesburg’s experience shows what can happen when waste collection, recycling and disposal systems fail to keep pace with demand.
For many African cities, simply building more landfills will not solve the problem.
Instead, authorities may need to improve collection, expand recycling, support waste reclaimers and encourage households to separate waste.
Ultimately, the goal is to reduce how much rubbish reaches landfills in the first place.
As one waste-management expert put it, the key question is simple: when people throw something away, where does it actually go?
