The Pulp and Paper Making Processes

To effectively track and quantify the flow of carbon, a material balance and hence a carbon balance over each of the pulp mills was conducted. The data used for generating the mass balances was sourced from each of the pulp mills investigated, and in some instances, estimations have been made from …

Carbon in Pulp Plant

The pulp produced is defiberized in refiners, screened and washed before being sent to the paper mill. In the paper mill the pulp is mechanically treated in beaters to improve fibre-to-fibre bonding and the strength of the paper. The pH level of the pulp slurry can be adjusted in some cases to facilitate the paper production.
