Stockholm University researchers have developed new method to produce new lignin-based materials and this new method is a resource-efficient method. These materials can substitute thermosetting resins and adhesives as these materials are thermally reprocessed. We need to find alternatives that are produced from fossil oil and gas resources. Though thermosetting resins have good performance but these synthetic plastics cannot be recycled.
Researchers have developed a new method to produce a material that can replace thermosets and that can be thermally reprocessed. Researchers mixed lignin with a non-toxic chemical derived from ethylene glycol in this new method.
Lignin can be used many times. To prove this statement, researchers first measured mechanical strength of lignin and then they measured the strength of the same material reprocessed form fractured sample. The mechanical strength remained unchanged.
