A novel method to extract lignin could help spin wheat straw into gold. Lignin produced using the new method was color-neutral, odorless and homogenous, an advance that could make this carbon-neutral material a more viable candidate for development of high-value products. Researchers extracted up to 93% lignin with up to 98% purity from wheat straw, producing a significant amount of material in a uniform way that could make it more attractive for industry use.
