Thanks to the binding, dispersing, emulsifying and sequestering properties of lignin-based polymers, SAPPI uses them in applications such as bricks, particle boards and recycled packaging. Lignopure uses them as additives to products to strengthen them, protect them from fire and UV, and as antioxidants.
Chemical company Evonik regards lignin as a promising candidate for the development of high-performance polymers, through electrolysis (using renewable energy). In the near future, lifestyle products such as sunglasses could be manufactured with polyamides made from lignin-based monomers. The same applies to parts that are currently made of steel and other metals, for example, in the automotive and construction industries.
Another new application for lignin is a widely supported project initiated by Circular Biobased Delta to reduce the carbon footprint of road construction and significantly reduce CO2 emissions by using lignin as a substitute for fossil bitumen in asphalt.
