Ghana’s mounting waste challenge is drawing renewed attention from policy and investment circles, not merely as a sanitation concern but as a potential frontier for infrastructure financing and energy generation.
With urban centres such as Accra producing increasing volumes of municipal solid waste each day, analysts say the country is sitting on a largely overlooked asset class, one that could be structured into commercially viable waste-to-energy (WtE) projects capable of delivering both financial returns and public utility.
At the centre of this argument is Dr. Elikplim Kwabla Apetorgbor, who has been advocating for a shift in how waste is understood within Ghana’s economic framework. He argues that waste should no longer be treated solely as a public service burden, but as a consistent and predictable input capable of underpinning long-term infrastructure investments.
Unlike conventional fuel sources subject to global price volatility, municipal waste is locally generated and relatively stable in supply, particularly in densely populated urban areas. This reliability, he notes, positions waste-to-energy as a form of dispatchable power—electricity that can be generated consistently to complement intermittent renewable sources such as solar.
For Ghana, where the power system continues to balance fuel constraints and hydrological variability, this presents a strategic opportunity to diversify the energy mix using a resource that is already embedded within urban activity.

Dr. Apetorgbor further highlights that the investment case extends beyond electricity generation. Well-structured WtE projects typically combine power sales with tipping fees, charges paid for waste disposal, creating a dual-revenue model that can improve project bankability and attract private capital.
“The opportunity is not just in building a power plant,” he notes. “It is in structuring an entire value chain where waste collection, processing, and energy generation are commercially linked.”
However, unlocking this potential will depend heavily on regulatory clarity and institutional coordination. Key issues include long-term waste supply agreements, transparent tariff structures, and credible off-take arrangements with the Electricity Company of Ghana to guarantee revenue from power generation.
Without these fundamentals, even technically sound projects may struggle to reach financial close, limiting the sector’s ability to attract sustained investment.
Operational risks also remain. Feedstock quality, efficient collection systems, and strict environmental compliance standards will be critical to ensuring that projects deliver both economic and environmental value. Poorly structured systems risk undermining investor confidence and public trust.
Globally, cities that have successfully integrated waste-to-energy into their infrastructure mix have done so through disciplined planning, strong regulatory oversight, and bankable contractual frameworks. Ghana, Dr. Apetorgbor argues, will need to replicate these conditions if it is to unlock meaningful investment in the sector.
Beyond investor returns, the broader economic implications are significant. Reduced reliance on landfills could free up urban land for higher-value use, while improved waste management systems could lower the economic costs associated with flooding, public health risks, and environmental degradation.
As urbanisation accelerates and waste volumes continue to rise, the pressure to rethink traditional disposal models is intensifying. What has long been treated as an unavoidable cost centre is now being reframed as a potential revenue-generating infrastructure segment.
