When waste blocked Accra’s drains during heavy rainfall, causing tragic floods in 2015, software engineer Prince Agbata started Coliba to solve Ghana’s refuse problem. The waste management company built Ghana’s first recycling infrastructure - collection centers and a digital platform to locate them - helping to increase Ghana’s recycling rate by 500%. Offering cash and other incentives in exchange for people’s segregated waste, Coliba processes and sells recyclables to international recyclers who use them to make products like clothing and new bottles. Prince’s envisioned expansion to other West African countries will enable his circular economy business to create more jobs, reduce waste, and grow a regional green economy.
