Contract manufacturing - Chemical modification of biomass

Novel bio-based materials

KCL has an extensive knowledge on various chemical modifications of cellulose pulp and biomaterials.

We have dedicated reactors and proprietary processes for esterification or etherification of cellulose fibers, like carboxymethylation, phosphorylation, sulphation or cationization of cellulose. The products can be fully washed after reaction and any harmful components captured and recovered and/or recycled from the related sidestreams using our advanced ultrafiltration systems. In addition, full OPEX/CAPEX analysis can be performed for tailored chemical processes to facilitate customers investment projects.


The derivatized biomaterials can be further analysed in our laboratory and full characteristics and fiber dimensions and chemical compositions can be studied.
