Recyclables from wood waste for energy storage and environmental technology

Research team takes lignin waste from the timber industry to develop materials that can be used to build and recycle sustainable batteries

05-Jul-2024 - The biopolymer lignin is found in large quantities in trees. It ensures that the wood of the trees remains stable. If this wood is processed into paper, for example, only the cellulose part of the wood is of interest. The lignin remains – almost half of the tree's mass. "The pulp industry ...
