Recycled paper is made from waste paper, collected from offices, printing companies etc. The waste paper is de-inked, i.e. the printing ink is cleaned from the fibres, the fibres bleached and new pulp produced which can be used in the production of new paper (recycled paper). Recycled paper is less harmful to the environment than paper made from fresh (virgin) fibres.
This involves the refining of offset paper, in which the surface is coated with a low ink comprising chalk and kaolin.
When the surface is later calendered (glazed) the surface appears either matt or shiny.
Products with a 100% recycled label support re-use of forest resources and in accordance with® standards, use post-consumer fibre.
One of the main reasons is our stringent selection of waste paper. The Greenfield de-inking mill focuses on recycling top quality waste paper ensuring the highest quality level of recycled pulp. Cocoon’s high whiteness is also the result of the advanced design of recycling and cleaning processes at Greenfield.
The recycled pulp production process uses a multi stage cleaning process. It uses biodegradable cleaners and chlorine free bleaches. The recycled pulp passes through 3 separate cleaning loops designed to be extremely efficient at extracting ink and are chlorine free.
Sodium Hydrosulphite, a reductive bleach, is used to remove colour from the fi bres and Hydrogen peroxide; an oxidative bleach, is used to brighten the fibres. It’s a sustainable process, for example the Hydrogen peroxide breaks down into water and oxygen upon disposal. This leads to a high quality and white recycled pulp, so very limited quantities of optical brightening agents are added to enhance the whiteness and brightness of the paper. Although the de-inking process uses water and chemicals, it is still less harmful to the environment than the manufacturing process of making paper from virgin fibre.
The result is a paper with a whiteness of 150 CIE produced with the environment very much in mind.
