Africa’s Waste Renaissance: How Incineration is Redefining the Way We Think About Waste

About 50 million people in Sub-Saharan Africa currently live in settlements with inadequate sanitation, and around 70% of the world’s waste generated by cities remains unmanaged or uncollected. This means that waste continues to accumulate on the streets, contributing to unhealthy and unsightly living conditions, and posing serious risks to the health and environment.

However, Africa is embracing a new way of thinking about waste, focusing on innovative waste management solutions like incineration. Incineration, which involves burning organic waste at very high temperatures, has been used in many developed countries for years to reduce waste and generate clean energy. The technology has long been considered viable, but lack of infrastructure, financing, and public awareness in Africa have delayed its adoption until now.

Incineration as a sustainable waste management strategy

Incineration is particularly suitable for waste management in African cities, as it can deal with the mixed waste streams typically found in many of these environments. The heat generated during incineration is enough to incinerate nearly all types of organic waste, from food to household waste and medical waste.

Benefits of incineration in Africa

  1. Cleaner Energy Generation: The energy generated during incineration can be captured and used for heating, generating electricity, and powering industries.

  2. Waste Disposal: Incineration removes waste from urban environments, creating cleaner and safer spaces for the residents.

  3. Pollution Reduction: The high temperature reached during incineration incinerates pathogenic microorganisms, reducing the risk of airborne and water-borne diseases transmission.

  4. Job Creation: Incineration plants are known to employ many people and can contribute significantly to the regional economy.

Challenges in implementing incineration in Africa

  1. Infrastructure Challenges: Incineration requires dedicated facilities, skilled personnel, and high-quality ash handling systems to minimize environmental harm.

  2. Public Resistance: Many citizens may be reluctant to adopt the technology due to misconceptions or fear of exposure to toxic materials.

  3. Financing: Incineration plants often require significant funding, which is difficult to find, especially for countries with low financial resources.

  4. Scalability: Incineration plants of various capacities have been built for smaller and larger populations, scaling the technology poses significant challenges

Conclusion:

Africa is witnessing a growing momentum towards transforming the way we manage waste through incineration. The need for innovative, effective, and environmentally friendly solutions has never been more pressing than today. This transformation is more than just technological, it will also require coordination and collaboration at multiple levels between government, stakeholders, and individuals.
