Turning Trash Into Treasure In Ghana: A public-private sector collaboration in an AI-enhanced recycling environment for a sustainable future

Ghana’s urban centres are drowning in waste, with over 1.1 million tons generated annually, yet only a fraction is managed properly. This mounting crisis is not just about overflowing landfills and polluted water bodies—it is a direct threat to public health, environmental sustainability, and the nation’s economy. Poor waste management is fueling the spread of diseases like cholera, contaminating water sources, and clogging drainage systems, leading to severe urban flooding at the least rainfall. The situation is critical, and if left unaddressed, the consequences will only worsen for future generations.

At the heart of this crisis lies Ghana’s infrastructural deficit. Waste collection systems are outdated and inefficient, while landfills are poorly managed and nearing capacity. Compounding this is irresponsible public behaviour—indiscriminate dumping in streets, rivers, and open spaces has become all too common. Public participation in waste management is minimal, even as the country’s urban populations continue to grow.

Despite existing regulatory frameworks led by the Environmental Protection Agency (EPA), whose main responsibilities in waste management are outlined under the EPA Act 490 (1994) and subsequent policies, the Ministry of Sanitation and Water Resources, the Ministry of Science, Technology, and Innovation, and the Metropolitan, Municipal, and District Assemblies (MMDAs), these institutions are struggling to manage the escalating waste problem. Weak enforcement, underfunding, and a lack of coordination between agencies have rendered these regulatory bodies ineffective. The MMDAs, in particular, face logistical hurdles and insufficient resources, leaving many urban areas with limited or no waste collection services.

• SDG 3: Good Health and Well-Being – Waste mismanagement fosters disease outbreaks, directly endangering public health.
• SDG 6: Clean Water and Sanitation – Mismanaged waste contaminates vital water bodies, threatening access to clean water for millions.
• SDG 11: Sustainable Cities and Communities – Sustainable urban development is impossible without effective waste management systems.
• SDG 12: Responsible Consumption and Production – Low recycling rates and high landfill use undermine efforts for sustainable consumption.
• SDG 13: Climate Action – Inefficient waste management exacerbates greenhouse gas emissions, intensifying climate change impacts.

Yet, within this crisis lies a powerful opportunity. Waste can be transformed into a resource rather than a burden. By leveraging AI and fostering public-private partnerships, Ghana can reimagine its waste management systems. The public sector can lay the groundwork through policy reforms and infrastructure development, while the private sector leads innovation, investing in AI-enhanced recycling, composting, and waste-to-energy solutions. Together, these efforts can turn waste into a driver of sustainable development, helping Ghana achieve its SDGs and build a greener, more prosperous future.

THE CURRENT STATE OF WASTE MANAGEMENT IN GHANA

Ghana’s waste management system is at a critical breaking point, largely due to rapid urbanization and a steadily growing population. Every day, the country generates approximately 14,232 tons of solid waste, with urban centres like Accra and Kumasi accounting for the majority. According to the Ghana Statistical Service, the average Ghanaian produces 0.47 kg of waste per day. While this figure may seem manageable, when multiplied across millions of people, it presents a substantial challenge for waste collection systems already stretched beyond capacity.

Unfortunately, more than 70% of this waste is improperly managed. Overflowing landfills, clogged drainage systems, and the increasing presence of waste in rivers and coastal areas are common sights. The country’s waste composition reveals another critical issue—14% of waste is non-biodegradable plastic, which poses a severe threat to the environment, especially to marine ecosystems and the livelihoods of communities that depend on clean water sources.

Traditional waste disposal methods, such as landfilling and open burning, are not only outdated but are also exacerbating environmental and health issues. Landfills are approaching capacity and are often poorly managed, while the open burning of waste releases dangerous toxins into the air, contributing to poor air quality and respiratory illnesses. The environmental damage is further intensified by the release of methane from landfills—a potent greenhouse gas that accelerates climate change.

These challenges have had significant impacts on public health and urban infrastructure. Seasonal cholera outbreaks are a common consequence of waste-clogged waterways and inadequate sanitation. The nation’s health system bears the brunt, with healthcare facilities constantly stretched due to illnesses linked directly to poor waste management.

This grim reality calls for immediate intervention, and one promising solution lies in the adoption of AI-powered technologies that can optimize waste sorting, recycling, and collection processes, reducing both environmental damage and operational inefficiencies.

THE ENVIRONMENTAL AND SCIO-ECONOMIC IMPACT OF URBAN WASTE

The mismanagement of urban waste in Ghana has far-reaching implications that extend well beyond environmental concerns. It impacts water bodies, air quality, public health, and the economy, creating a vicious cycle of degradation and loss.

1. Water Pollution

One of the most visible and damaging effects of urban waste mismanagement is the pollution of Ghana’s rivers, lakes, and coastal areas. Plastics, which constitute around 14% of the country’s waste, are especially problematic. These non-biodegradable materials persist in the environment for hundreds of years, choking water bodies and disrupting ecosystems. During the rainy season, clogged drainage systems caused by waste contribute to urban flooding, which further spreads contamination.

For communities that depend on these water bodies for fishing, agriculture, or even drinking water, the consequences are dire. Contaminated water leads to serious health risks, while damaged ecosystems disrupt livelihoods, particularly in rural and coastal communities.

2. Air Pollution

Open burning remains a common method of waste disposal, particularly in densely populated urban areas. This practice releases dangerous toxins such as carbon monoxide, dioxins, and particulate matter, which degrade air quality and increase the incidence of respiratory illnesses. In communities near landfills or informal waste-burning sites, the health risks are significantly higher.

Moreover, the release of black carbon during waste combustion accelerates global warming. This not only contributes to climate change but also exacerbates its impacts, such as rising temperatures and more frequent extreme weather events.

3. Public Health Risks

Over 70% of the health problems reported in outpatient clinics across Ghana are linked to poor sanitation and waste management. Diseases such as cholera, diarrhoea, and respiratory infections are rampant in urban areas where waste regularly clogs open drains, contaminates water supplies, and pollutes the air. According to data from the Ghana Health Service, an estimated 13,900 adults and 5,100 children under the age of five die annually from diarrheal diseases, with over 90% of these deaths directly attributable to poor sanitation and hygiene practices

4. Economic Impact

The financial burden of poor waste management is staggering. The Waste and Sanitation Programme (WSP) estimates that Ghana loses around $290 million annually due to the negative effects of indiscriminate waste disposal. This figure accounts for 1.6% of the nation’s GDP—funds that could otherwise be allocated to improving infrastructure, healthcare, and sustainable development initiatives. If the waste management crisis continues unaddressed, these economic losses will only increase, further straining the country’s resources.

However, with the right strategies, particularly those involving AI and public-private partnerships, Ghana has the opportunity to reverse these negative trends. Waste can be transformed from a source of pollution into a valuable resource, contributing to economic growth and public health improvement.

PUBLIC-PRIVATE COLLABORATION TO UNLOCK THE POTENTIAL OF AI IN WASTE MANAGEMENT

Addressing Ghana’s waste management crisis will require collaboration between the public and private sectors, with AI technology playing a pivotal role. Each sector brings unique strengths—government institutions offer the necessary policy frameworks and infrastructure, while private companies bring technological innovation and investment.
