Lignin can be found in the cell walls of all plants and it is one of the most abundant biopolymers on Earth. Lignin is nature’s own “glue” due to its polymeric nature and its richness in functional groups.
Currently, kraft lignin and lignosulphonate are available in industrial scale. UPM BioPiva is kraft lignin originating from pulping processes. Unlike lignosulfonate it is not readily water soluble.
In nature lignin provides strength and protects plants against UV irradiation as well as fungal and bacterial attack. Due to these properties, lignin can be used in various applications. For example, it replaces fossil phenol and formaldehyde in phenolic resins. In other polymer systems, it can be used as a structural component as well as a functional filler.
In addition to high quality UPM BioPiva lignin, we also provide expertise and customer support for developing new lignin applications.
Lignin is cost effective compared to many fossil alternatives.
Lignin is produced in large quantities in industrial processes and from consistent raw material streams. UPM has also tight quality control schemes in place for its lignin products.
