Abstract

Chemical system that makes it possible in a cost effective and environmentally friendly way to deink waste paper at a lower pH than required in present methods, but with retained efficiency and quality. This has been obtained by a chemical system comprising the following components: a) a surface-active ester to release the printing-ink from the pulp fibers, b) a polyester based collector for aggregation and flotation of released printing-ink particles. The system may also contain an inhibitor for hydrogen peroxide decomposing enzymes, such as peroxidase and catalase.
