Refining biomass into speciality products

Protobind 1000 

Protobind 1000 is a sulphur free lignin generated from soda pulping of annual fibres such as wheat straw and is available as a dry powder product with low ash and sugars impurities. There are plenty of applications such as high-purity dispersants, animal feed, pharmaceutical supplements, cosmetics, and polymeric composites which require high purity and cannot bear sulphur in their structure.

Protobind KW 

Protobind KW is kraft lignin produced from kraft pulping of hardwood and is available as a dry powder product with high purity. Kraft lignin is used for replacing phenol in phenol formaldehyde adhesives used for the manufacture of particular wood-based composites such as plywood, laminated veneer, fibreboard, particleboard and paper-based laminates.

Plywood is type of engineered wood consisted of two or more layers of boards glued together. Phenol formaldehyde resin is widely used for manufacturing plywood and many resin manufactures are partially utilizing lignin as a bio-based replacement for phenol in their resin.

 

Paper-based laminates are consisted of several layers of Kraft paper impregnated with phenol-formaldehyde resins and covered with decorative and overlay paper on both sides. This type of industries is using Lignin as a partial phenol replacement in their resin.
