Lignin
Lignin is a natural matrix material which binds the strong and stiff cellulose units together in, for example, natural wood. Once separated, it can be chemically modified or blended to produce a thermoplastic-type polymer which can be heated and processed like synthetic thermoplastics. Lignin can be in the form of a brown powder, but more often it is a gummy mixture with a wide range of molecular weights. It is a by-product of the pulp industry and the volume arising worldwide is about 50 million tonnes per year. With the decline of the paper industry, paper mills and woodland owners are looking at developing and commercialising other products and technologies utilising wood, and lignin could become an important feedstock for production of many chemicals.
Depending in your needs we supply you the best-suitable lignin. Furthermore, contract functionalization of lignin is an essential part of our competence.
