We eat millions of tonnes of coconuts every year - with the dense white flesh of the fruit making a tasty snack and the juice a refreshing drink.

But the inedible husk and shell go to waste – and it’s this part that innovators and entrepreneurs around the world are now putting to work to solve a whole host of problems.

In Sierra Leone, a personal tragedy was the catalyst for young entrepreneur Alhaji Siraj Bah to start a business which takes the coconut husk and turns it into an alternative to charcoal - which is good for the forests and could potentially save lives too.

And we hear about the start-up using coconut to keep fish, fruit and vegetables cool for longer without using any plastic.
