One of industry's toughest lignin byproducts could become feedstock for valuable chemicals
Researchers at Lawrence Berkeley National Laboratory have developed a new method to convert kraft lignin, a difficult-to-process industrial byproduct, into valuable benzylamines. This process offers a sustainable alternative to traditional, toxic chemical manufacturing methods.
Why it matters
This breakthrough could significantly reduce industrial waste and provide a greener supply chain for essential products like fertilizers and pharmaceuticals.

DOI: 10.1016/j.cej.2026.174287 The pulp and paper industry, which manufactures everything from tissue paper to cardboard, also generates a significant yet often overlooked byproduct—a complex polymer called lignin. Around 100 million tons of lignin are produced each year. Despite being the largest natural source of aromatic carbon on the planet, most of it is burned for energy. This is due to its complex structure, which is notoriously difficult to process. Researchers are exploring ways to leverage industrial lignin by developing methods to convert it into useful bio-based chemicals.
