FAQ EN

• What is recycled pulp?

  Recycled or deinked pulp is produced from recovered waste paper which achieves the re-introduction of cellulose fiber into the papermaking process.

• What type of paper can be made with de-inked pulp?

  Today, recycled pulp is used to make all types of paper from newsprint to photocopy including writing and fine papers.

• How does GREENFIELD’s deinked pulp get so white?

  Firstly, through a stringent selection of recovered waste paper, mainly Sorted Office Waste (SOW). Secondly, using two bleaching stages, ie. Hydrogen peroxyde followed by sodium hydrosulfite, both non polluting chemicals.

• Why is the dirt content in GREENFIELD deinked pulp so low ?

  The recycling process has multiple deinking and cleaning stages allowing us to remove 99% of incoming contaminants (ink, staples, glue, sand, glass...).

• What is the difference between a “raw” or natural deinked pulp and a “bleached” deinked pulp?

  Depending on the quality of recovered paper and the sophistication of the recycling process, pulp tint or brightness can be “raw” (grey tint) or white like ours.

• Where does the recovered paper recycled by GREENFIELD come from?

  Waste paper recycled at the GREENFIELD mill comes mainly from office recycling bins.
  This SOW (Sorted Office Waste) is collected by recycling specialists and organisations who sort various types of paper according to whiteness and composition and then send them in bales to the mill.

• What is the “FSC recycled” label?

  While an “FSC” (Forest Stewarship Council) label guarantees that wood used comes from forests managed according to standards that respect ecological, social and economic criteria, the “FSC recycled” label guarantee that recycled fibers come from post-consumer sources. This is waste paper discarded by the final user as opposed to “broke” from a paper machine.

• What is deinking sludge?

  When waste paper is recycled, the purpose is to recover cellulose fibers. The recycling process will separate these fibers from other materials that make up the paper : clay or mineral coatings/fillers and ink. As a by-product of the recycling process, fine cellulose fibers are also extracted. These “fines” are the result of multiple recyclings. These three elements : mineral charges, fibers and ink (<1%) will make up the deinking waste sludge which can also be re-used.
  We call this by-product CALCIFIED and it is completely environmentally friendly.

  At GREENFIELD, deinking sludge is supplied as a soil fertilizer or used in brick manufacturing.
