Projects on paper and pulp
A short overview is given on projects relating to paper and pulp. For more information on this field, please visit the paper and board site of Wageningen UR.
------------------------
Product and market development for sisal
A feasibility study of pulp and paper production from sisal leaf fibre and sisal waste in East African region was performed. Introduction of adapted agronomy for pulp production purposes, development of dedicated decortication technology and worldwide market study to develop markets for the targeted products. Wageningen UR was involved in the worldwide project management and in selected parts of the (confirmatory) pulping and bleaching trials and training of project personnel.
------------------------
Biopulping & biobleaching of jute and kenaf
Participation in a CFC funded project for development of pulping technology and logistics for jute stick and whole kenaf for Bangladesh, India and China. The participation of Wageningen UR comprised the development of biomechanical processing for bast fibre crops.
------------------------
Chemi-mechanical pulping of Empty fruit bunch
Evaluation of refiner-based CTMP pulping of palm-oil residues for application in packaging papers and boards in Asia.
------------------------
Hemp for graphic paper, graphic board and packaging board
A study was performed to evaluate bleached chemi-mechanical pulp from the core fibre of hemp for improvement of sheet formation and porosity control in uncoated graphic paper. Also a study was performed to evaluate bleached chemi-mechanical pulp from the bast fibre of hemp and flax as a replacement for cotton linter pulp.
The performance of a variety of hemp core pulps for improvement of internal bond in multilayered boards was evaluated and found to be very good.
------------------------
Agrofibre as source for high DP cellulose for dissolving cellulose and CMC
Cellulose from bast fibres was found to have an extremely high degree of polymerisation (DP). This material is potentially interesting to produce high-DP modified cellulose such as carboxymethylcellulose and celluloseacetate. The standard alkaline/chlorine dioxide extraction and purification process for cellulose was adapted to yield pure high DP cellulose as base for modifications by the customer.
