E-waste in Africa is piling up—currently estimated at 2.9 million tonnes annually. Most of it ends up in landfills or gets handled by the informal sector, which poses serious health risks due to toxic materials like mercury and lead. Recycling efforts remain low, with only about 4% formally recycled. But there’s a growing hero on the scene: Artificial Intelligence (AI).
In Africa, AI isn’t just for robots and self-driving cars—it’s helping solve the e-waste problem. AI-driven systems are emerging, particularly in South Africa and Nigeria, transforming how e-waste is sorted and processed. By using machine learning algorithms, these systems can efficiently sort different types of waste, saving time and resources and making recycling more effective. For instance, AI can now identify the types of materials in e-waste, enabling quicker separation for proper recycling.
According to a study on ResearchGate comparing AI-driven innovations in the U.S. and Africa, the continent is making strides, though it still faces challenges like insufficient infrastructure and funding. Nonetheless, AI’s ability to predict and optimize waste management processes offers hope for a more circular economy.
Examples of countries in Africa stepping up their AI games?
In Kenya, AI-based predictive maintenance systems help extend the life of electronic devices. By using sensors and data analysis, AI can predict when devices will break down, reducing the need for premature disposal. This reduces the waste generated and keeps products in use longer. AI is also helping connect users with recycles through platforms that match those with old electronics to companies that specialize in dismantling or refurbishing these devices.
In 2023, Rwanda launched a national AI strategy that goes beyond education and healthcare to include waste management. While it’s still in the early stages, Rwanda’s plan could serve as a blueprint for other African nations. By incorporating AI into waste management, Rwanda aims to improve recycling rates and reduce the environmental impact of e-waste. Their goal is to create a smart system that not only collects and sorts e-waste but also turns it into new products.
Ghana is working with international AI organizations to build a better recycling infrastructure. By partnering with tech giants and local startups, Ghana is exploring how AI can streamline the recycling process, improve safety for workers, and minimize environmental damage.
The Future: Bright but Challenging
Despite the exciting advancements, there are challenges ahead. Africa still lacks the large-scale infrastructure found in countries like the U.S., and funding remains a hurdle. However, with global attention on sustainability and the circular economy, AI is set to play a crucial role in addressing these issues.
