Papermaking chemistry aspects of using environmentally-friendly ECF and TCF pulps

Objectives

Chemical additives are more and more important for an effective manufacture of high quality paper products. The background of this project is the importance of chemical additives (paper chemicals) in paper manufacture and the rapidly increasing use of new types of non-chlorine bleached pulps, i.e. elementary chlorine-free (ECF) and totally chlorine-free (TCF) pulps.

Technical Approach

The overall objectives of the project are to find solutions to problems in the papermaking chemistry when using the new types of non-chlorine pulps, ECF and TCF pulps. To enable this goal there is need to build up a thorough knowledge of the systems involved. This project is an important step in the work towards an ecocyclic system in pulp and paper production. The project will strengthen the scientific base needed to protect the environment.

Expected Results

I. Direct Results

increased fundamental knowledge on the interaction between disturbing substances and performance chemicals added in papermaking
increased knowledge about the papermaking chemistry at high degrees of system closure
development of microscopic techniques for chemical topography of ECF and TCF chemical pulps
incorporation of the dynamics of paper performance chemicals into dynamic simulation software for the simulation of the wet end of paper machines

II. Indirect Results

increased productivity in papermaking due to optimisation of added performance chemicals
possibilities to optimise the papermaking chemistry and to decrease the load of effluents on the environment

Applications

Paper mills producing other paper grades that do not contain ECF and TCF chemical pulps, e.g. newsprint, liquid packaging board, can use the methodology developed in the project.
