Researchers found a way to make bioethanol from sugarcane waste more efficiently. They used a special chemical treatment on the waste to break down the tough parts and make it easier to turn into fuel. This treatment also helped plants grow better when the leftover chemicals were used as fertilizer. The process doesn't need extra steps like separating solids or cleaning with water, making it simpler and more eco-friendly. This method could lead to higher bioethanol production and other useful products from agricultural leftovers.
