In the context of the Afri-Plastics Challenge, a Canadian government initiative tackling marine plastic pollution in Sub-Saharan Africa, we conducted a market research due diligence assessment of enrolled social enterprises. Our objective was to evaluate the potential and impact of their proposed solutions for plastic waste management. This involved in-depth research on each venture’s business model, target market, and proposed technology or approach. By analyzing their financial viability, scalability, and alignment with the Challenge’s goals, we aimed to identify the most promising social enterprises capable of significantly reducing plastic waste and fostering a more sustainable future for the region.
