Ghana could generate energy by separating household waste, according to Lukman Salifu, CEO of Waste Care Associates. He states that a two-bin system, dividing waste into organic and inorganic streams, would support waste-to-energy operations.
This separation allows different treatment processes for each waste type. Organic waste can undergo biomethanation to produce biogas, a renewable energy source. Inorganic waste can be incinerated to generate electricity, providing a dual benefit for energy production.
This proposal fits into Ghana's broader efforts to improve waste management and secure energy. Ghana faces significant challenges with waste disposal and energy supply. The country is exploring various sustainable solutions to these pressing issues.
Mr. Salifu, a public health engineering expert, made these remarks during an interview on JoyFM's Super Morning Show. He was responding to recent proposals by Local Government Minister Mahama Ayarigah. Minister Ayarigah had urged assemblies to secure land for waste transfer stations and landfill sites.
Implementing such a system has several implications for Ghana. It could reduce the volume of waste sent to landfills, extending their lifespan. It also offers a new, local source of energy, potentially reducing reliance on other power sources. Decision-makers will need to consider infrastructure investments and public adoption for this system.
Mr. Salifu highlighted that nearly 60% of Ghana's solid waste is organic. This high percentage makes biomethanation a particularly viable option for energy generation. He emphasized that the two-bin approach would be straightforward for households to adopt.
He urged Accra, the capital city, to prioritize waste-to-energy technologies. This focus could transform a major urban waste problem into an energy asset. However, Mr. Salifu also noted that Ghana still requires landfill facilities alongside modern treatment technologies. The choice of technology depends on local conditions and land availability.
The integration of waste separation at the household level is crucial for the success of waste-to-energy plants. Without proper sorting at the source, the efficiency of these energy conversion processes decreases significantly. This initiative could also create new jobs in waste collection, processing, and energy production sectors.
This approach aligns with global trends towards circular economy principles. These principles aim to minimize waste and maximize resource utilization. Ghana's adoption of such systems could position it as a leader in sustainable waste management in the region.
The government and local assemblies would need to invest in public education campaigns. These campaigns would inform citizens about the benefits and methods of waste separation. Such efforts are vital for widespread community participation and the long-term success of the program.
