There are basically four materials in low cost recycle that give it a bad name. Ink, stickies, plastics and ash. Sorted office waste and DLK have less of these unwanted materials but has a higher cost due to collection, sorting and quantity of good fiber. Availability also has an impact on cost. Added operating costs of recycle, normally blamed on stickies and ink, always impact overall profitability. These indirect expenses are lower production due to slower speeds and downtime, poor quality due to spots and holes, lower brightness, lower yield, cleaning and control chemistries and poor process water quality should be a consideration.
