Ghana's Landfill Crisis: Expert Demands Urgent Shift Toward National Waste Diversion and Recycling

Ghana is currently facing a looming sanitation crisis as its traditional methods of waste disposal become increasingly unsustainable. Dr Ted Yemoh Annang, a Senior Research Fellow at the University of Ghana's Institute for Environment and Sanitation Studies, has sounded a strong warning regarding the country's over-reliance on landfill sites. Speaking on Monday, July 13, during an extensive discussion on waste disposal on Joy FM's Super Morning Show, the environmental expert emphasised that the current practice of transporting virtually all generated waste directly to landfills is rapidly exhausting the nation's disposal infrastructure.

The core issue, according to Dr Annang, lies in the complete lack of waste diversion strategies within the national waste management framework. Ghana's municipal solid waste stream is heavily composed of organic, biodegradable materials, yet the current system makes little to no effort to separate these from plastics, metals, and other recyclables prior to final disposal. This indiscriminate dumping means that landfills, which require significant capital investment and vast land resources, are reaching their capacity long before their designed lifespans have been realised.

The Necessity of Waste Diversion

Waste diversion is a fundamental pillar of modern, sustainable environmental management. It involves identifying and extracting materials that still hold economic or practical value before they are permanently discarded. Dr Annang noted that the primary goal of treatment prior to disposal is to extend the life of these materials, effectively transitioning the country toward a more sustainable circular economy.

"So there is this issue about waste diversion. Waste diversion means that if you look at the treatment portion, treatment before disposal, the treatment is just meant to give the waste material extended life," Dr Annang explained during the broadcast.

He argued forcefully that landfills are strictly meant for "end-of-life" waste -- materials that have absolutely no further utility, cannot be recycled, and cannot be repurposed in any meaningful way. By flooding these designated sites with organic matter and recyclable plastics, the nation is fundamentally mismanaging its resources and drastically accelerating the depletion of available landfill space.

Currently, the standard procedure involves moving waste straight from the point of collection to the landfill site without any intermediate sorting or processing. Because these sites receive everything indiscriminately, they fill up prematurely, undermining the engineering and planning that went into their construction.

The Heavy Burden of Organic Waste

A significant portion of Ghana's daily waste is generated in high-density commercial areas, particularly the traditional markets that serve as the economic lifeblood of many urban and peri-urban communities. Dr Annang used these vibrant commercial hubs to illustrate the massive scale of the missed opportunity in the country's current waste management approach.

He pointed out that the large heaps of garbage frequently seen in and around major market centres are overwhelmingly composed of materials that should never see the inside of a final disposal site.

"If we go to the market, where we always have heaps of garbage, more than 90 per cent of the garbage there is degradable. It's organic," he stated categorically.

If local authorities and waste management companies were to successfully separate this organic fraction, the sheer volume of residual waste destined for final disposal would be drastically reduced. The simple process of taking out biodegradable materials, alongside reusable plastics and bottles, would leave a very minimal portion of true waste to be managed at the landfill level.

To effectively manage this, Dr Annang highlighted the need to treat this organic bulk as a resource rather than a nuisance:

• Large-scale Composting: Converting the vast amounts of degradable market and household waste into nutrient-rich compost.
• Energy Conversion: Exploring ways to turn the massive volumes of organic waste into alternative energy sources.
• Source Separation: Ensuring that recyclable plastics and bottles are removed from the waste stream long before they reach the final disposal site.

Transitioning to Sustainable Resource Recovery

The prevailing mindset across many municipalities treats all discarded items as mere rubbish, a perspective that Dr Annang insists must be urgently dismantled. Instead of viewing waste as a problem to be hidden away in overflowing landfills, the country must begin to view it as a vital secondary resource.

Extending the lifecycle of materials such as plastics, metals, and paper through robust recycling and repurposing programmes is no longer optional; it is an absolute necessity. While organic waste forms the overwhelming bulk of the waste stream in this part of the world, non-degradable materials pose an equally severe threat to the environment if they are not systematically recovered.

"What we should be doing differently is to manage the waste. We manage the waste by focusing on extending the life of some aspects of the waste stream, like plastics, metals, and paper," he advised.

He further stressed the importance of addressing the organic component specifically: "Organic waste in this part of the world forms the bulk of the waste and must be diverted, composted, and turned into energy."

The Severe Cost of Continued Inaction

The long-term consequences of maintaining the status quo are undeniably stark. The expert cautioned that taking the easiest route -- simply dumping everything into a hole in the ground -- will never yield the better results the country desperately needs in its sanitation sector.

Whether society acknowledges it or not, human populations will continue to generate substantial amounts of waste on a daily basis. Because a portion of this waste is not directly degradable, recycling, repurposing, and recovering materials remain critical interventions. Without these proactive measures, Ghana faces a very grim reality in the near future.

If the current trajectory remains unaltered, the nation will soon find itself in a disastrous position where daily waste collection becomes a futile exercise simply because there is no physical space left to dump the collected refuse.

"Otherwise, we generate the waste, we store it, we collect it, but we won't have anywhere to send it because we don't have disposal sites," Dr Annang warned in his concluding remarks.

The message is unmistakably clear: unless there is a complete paradigm shift towards recycling, composting, and aggressive waste recovery, Ghana will continue to struggle indefinitely with an acute shortage of waste disposal sites, ultimately compromising public health and environmental integrity.
