A cardboard box is basically made up of a flute (made up of recycled paper), sandwiched between two liners. It is now very common for these liners to also be made up of a considerable portion of recycled content, sourced from old cardboard and/or other sources of second hand paper.
Using a recycled material, rather than a raw material conserves energy as well as natural resources and helps reduce pollution. Making the pulp used in cardboard, creates sulfur dioxide, a gas that causes acid rain. Recycling cardboard helps reduce that pollution.
Cardboard K4
Regular Corrugated Cardboard or OCC (Old Corrugated Cardboard) – is sold as K4Our K4 bales contribute up to 8% of other KRAFT materials i.e. , egg boxes, kraft packages, paperboard packaging, shredded cores, etc.).
This can be loose or baled.
Cores
Paper cores are strong cardboard tubes or cylinders which are used in fabric, adhesive, electrical, paper product and converting industries. To add value we shred our cores and add it to K4 in small percentages as it can be considered a contamination because of the glue.
Kraft Packaging
Kraft packaging can be added to K4 bales until 8%. It can also be added to our bales of Common paper, however this is a downgrade.
Paperboard Packaging
Paperboard packaging can be added to K4 bales until 8%. It can also be added to our bales of common paper, however this is a downgrade.
Wet Strength
Wet strength is not accepted in the pulp/paper mills, and plastic recycling factories. It´s hard to find a recycler for this recyclable.It can go to RDF or Landfill.
Cores / Kraft Sheets
To add value we should shred Cores/Kraft sheets, and add it to K4 in small percentages as it can be considered a contamination because of the glue.
Cores/Kraft sheets can also be sold as they are but for a much lower value.
Cardboard collected for recycling is sorted, graded and taken to a paper mill. From there, pulp is created and then screened, cleaned and turned into new material.
