Can you tell what it is?

You've heard of "green" fuel. Now get ready for yellow as scientists have found a way to turn banana waste into a sustainable fuel source that could be relevant to many countries across Africa. The simple, low-tech idea, was developed by researchers at Nottingham University.
They used banana skins to create briquettes that can be burned for cooking, lighting and heating. It could alleviate the burden of gathering firewood, the dominant energy source in many parts of the continent. This would help reduce deforestation, which makes a significant contribution to global climate change.
