Description
Hugo Duarte and ten colleagues published a materials study in two thousand twenty-four on rigid foams made from plant residues. Tannin foams already serve as fire-safe insulation. Replacing tannin with lignin, a paper industry byproduct, might add water-cleaning power.
Two lignins differing in size and acidity fully replaced tannin in the foam recipe. The alkali lignin foam soaked up methylene blue dye at two hundred twenty milligrams per gram, through a multilayer process. Foams survived at least five use-and-clean cycles. They also resisted flame effectively. The authors pitch the material as a double-duty product: building insulation that can also scrub dye from wastewater. Water scarcity and energy costs motivate the work.
