Circular economy is a waste management strategy that promotes sustainability by extending the lifecycle of materials through reuse, recycling, and innovative waste transformation methods. Unlike the traditional linear model, which focuses on disposal, the circular economy seeks to extract value from waste while reducing environmental harm. This study explores key circular economy strategies applicable to Africa such as Windrow composting, Microbial-Induced Carbonation (MIC) for construction waste recycling, brewery spent grain (BSG) upcycling into alternative protein sources, and the production of biodegradable soap from fruit peels. By adopting these circular economy strategies, Africa can reduce waste, minimize environmental impact, and create economic opportunities.
