Making smart, responsible choices means having a vision for the future. That includes the life cycle of your packaging.
Corrugated is the single most recycled packaging material on earth: 92.9 percent of corrugated produced in 2015 was recovered for recycling, and almost all of that material was recycled into new products.

Why Recycle?
Recycling corrugated helps decrease solid waste disposal in landfills. It also provides fibre that is reused to make new corrugated, so we can use less new, raw material. Recycling corrugated can even earn revenue for the end-user, because that recovered material is valuable to paper mills and manufacturers of new corrugated.

How Corrugated Recycling Works
Businesses, retailers and consumers at home collect and return their used corrugated containers to be recycled into new ones. While almost everyone contributes to corrugated’s recycling success, fewer people may know where those boxes go from the collection point, or how they are processed to produce new corrugated material.

  1. Corrugated boxes are used for their intended purpose of product protection and transportation.
  2. Clean, old corrugated containers (OCC) are collected, in many instances as part of a mixed recyclables
    stream. To optimize recyclability, containers should be free of contaminants such as food, metal foil, wax,
    etc.
  3. The collected OCC is sorted, compacted and baled for space-efficient storage and handling, either at the
    point of end-use (store or business) or at the recycling centre.
  4. Bales are transported to the paper mill.
  5. Bales are broken open, and OCC is put into a re-pulper (a huge tub that looks something like a blender) with
    water. It is agitated to form a slushy pulp (slurry) of fibre and water.
  6. a. A big “ragger” chain or rope hangs
    down into the swirling tub of material. Some contaminants such as long pieces of rope, string or tape, plastic
    and metal bands will wrap around the ragger and can then be pulled out of the re-pulper.
    b. The remaining pulp slurry goes through different types of equipment such as towers where
    the metal falls to the bottom for removal, screens, cyclones, and even big tanks where the contaminants float
    to the top and can be scraped off. The cleaned pulp is then sent to the paper machine.
  7. The highly diluted fibre solution is poured out onto a moving screen which allows water to drain away, forming
    a continuous fibre mat, which is pressed between rollers to remove more water.
  8. The wet, continuous fibre web is then wound through the dryer section where the top and bottom of the web
    alternately contact the heated surfaces of the drying cylinders, removing the remaining moisture from the
    paper.
  9. At the end of the paper machine, paper is rolled up on a large reel spool, which can weigh 10-60 tons.
  10. The reel is then slit and rewound into individual rolls that weigh approximately 3 tons each. The recycling
    process is complete; the new paper rolls are shipped to box manufacturers to begin the next stage in life to
    become new corrugated boxes.
