With the growing environmental concerns facing the pulp and paper industry, saving energy, an effective use of resources, utilization of waste paper and lightweight paper and paperboard come to tay as countermeasures. Use of recycled waste water and progress in closed system increasingly worsen water for papermaking.
The contribution to environmental concerns and new application to a coating chemical with the new PAM strength agent are outlined as compared to starch which brings disadvantage, for instance the complicated process of cooking, a declining rate of increase in strength at high addition levels and a rise in waste water load (COD).
Additionally, Neu Size 770, which can compare alkaline sizing agents (AKD, ASA) in sizing efficiency in neutral as well as alkaline paper making conditions without deposits and/or slippage problems, is summarized.
