Researchers have demonstrated that different types of paper industry sludge, typically treated as a low-value waste, can be transformed into a high-yield renewable biofuel. The study, published in Biofuels, Bioproducts and Biorefining, reveals that paper sludge streams vary significantly in their suitability for producing bioethanol and biogas, offering a pathway to more efficient waste-to-energy strategies.<\/p>\n
