Looking around the city, a businessman Kwabena Osei Bonsu decided something needed to be done. "I wanted to come up with an idea that would solve problems in my lifetime," he said. His solution? Collect the discarded plastic bags and stitch them together to make new, reusable bags.
In the Trashy Bags workshop a dozen tailors and seamstresses sit at manual sewing machines stitching together old plastic sachets. In west Africa tap water is not fit to drink so millions of half-litre "pure water" sachets costing only the equivalent of 2p are discarded by thirsty consumers every day.
