Here's a story highlighting some real business creativity: a group of South African entrepreneurs taking plastic bags and refashioning them into solar powered backpacks designed to give children light to study with.
Rethaka (Pty) Ltd., in Rustenburg, South Africa, collects the plastic bags and take them to its small factory, where they're cleaned and turned into a textile-like material.
Then it sews the material into backpacks, and adds a small, removable solar charger, which collects power as the kids walk home.
The chargers can be easily removed and screwed onto lamps made from mason jars. They then provide six to nine hours of light, crucial for studying if the kids are among the 1.3 billion people worldwide without regular access to electricity.
It's the brainchild of 22-year-old CEO Thato Kgatlhanye, who started it with some of her classmates in university in Johannesburg. According to this Forbes article, Kgatlhanye got the idea after noticing a lot of kids carrying their schoolbooks in plastic bags.
