Africa’s largest cities face growing waste challenges and decreasing space for disposal.
In the industrial suburb of Kya Sands, Johannesburg, an alarming sight looms. At the end of a narrow road, two men overlook a massive mound of illegally dumped waste, a stark reminder of the region’s ongoing waste management crisis. The heaps are not merely piles of refuse; they represent a growing environmental and public health challenge that has intensified since the municipal landfill closed in 2010 after reaching full capacity.
Devon Steenkamp, a local councilor who began his term in 2021, notes that what was once a modest heap of garbage has transformed into a towering mountain, choking the road with its size and emitting noxious fumes. What lies beneath this mound is merely the fringe of a far larger dump site that has expanded exponentially, with waste now spilling into the surrounding valley as lorries perpetually deliver more refuse.
This escalating waste issue in Johannesburg reflects a troubling trend across many rapidly urbanizing cities in Africa, including Lagos, Dakar, and Accra, where waste generation has outpaced municipalities’ capacity for collection, recycling, and safe disposal. As Africa’s urban population is projected to surge to 1.4 billion by 2050, the United Nations Environment Program warns that over 90% of the continent’s waste is disposed of at uncontrolled sites, with the World Bank forecasting a 124% rise in waste generation in sub-Saharan Africa within the same timeframe.
In Johannesburg’s densely populated Alexandria township, local residents face chaotic street conditions; goats forage through refuse-littered sidewalks, and concerned citizens like 75-year-old Linda Makole plead for better living conditions for the children who play in this contaminated environment. The municipal waste company, Pikitup, has identified more than 2,000 illegal dumping hotspots and allocated 115 million rand (approximately .4 million) to remediate these sites.
However, many residents report garbage being left uncollected for weeks on end, largely attributed to labor disputes, financial constraints, and an outdated fleet. Consequently, the demand for informal waste haulers has surged, complicating the situation further as these operators often lack proper disposal methods.
The pollution resulting from illegal dumping is alarming. Residents near dump sites contend with hazardous air quality; harmful substances are released into the environment, affecting both human health and local ecosystems. These informal sites are not only sources of toxic smoke but also contribute to the clogging of stormwater drains, thereby increasing flood risks.
Dr. Suzan Oelofse from South Africa’s Council for Scientific and Industrial Research highlights the urgency of addressing waste management, citing the unsustainable depletion of landfill space in Johannesburg as a critical concern. Recent studies reveal that the remaining capacity of municipal landfills is dwindling, with estimates suggesting that less than a year of disposal capacity remains.
Addressing this crisis necessitates systemic change. Dr. Oelofse estimates that up to 80% of Johannesburg’s waste could be diverted through effective recycling and organic waste treatment practices if residents and businesses begin to separate waste at its source. Pikitup is promoting these practices while seeking to expand recycling infrastructure and enhance collaboration with waste reclaimers.
Residents like Nomvula Phaliso, a recycler and law student, emphasize the need for greater support for waste pickers who currently play an essential role in diverting recyclable materials from landfills. To confront the persistent issues of waste management, a cultural shift in how individuals conceptualize disposal is imperative. Increasing awareness about the environmental implications of discarding waste can inform and motivate communities toward more sustainable practices.
As Johannesburg continues to grapple with its waste management dilemma, it stands as a microcosm of a dire situation affecting many urban centers across Africa. The challenge is vast, but with concerted efforts in community engagement and systemic reform, there remains hope for a more sustainable approach to waste management in the future.
