How a Ghanaian entrepreneur uses recycled plastic to make cheaper roads and building blocks
For Nelson Boateng, the plastics business is all he has known since he started working at a factory when he was 13. In 2015, fearing that a plastics ban was imminent, Boateng’s company, Nelplast, which makes plastic shopping bags, was pushed to think of a way to keep the business alive.
