Cardboard Recycling: Steps to Successful Cardboard Recycling

Cardboard recycling refers to the reprocessing and reuse of stiff multilayered papers that have been used or regarded as waste. There are two kinds of cardboard: corrugated cardboard and paperboard. The former is used to make brown packing boxes while the latter is used to make products such as shoe boxes, cereal boxes, and other packages.

Cardboard Recycling Process

1. Collection

Collection is the first step of the Cardboard Recycling Melbourne at AB Recycling process. Recyclers collect waste cardboard at designated collection areas such as scrap yards, trash bins, stores and commercial companies that generate cardboard waste.

2. Sorting

Once the cardboard materials arrive at the recycling facility, they are separated based on the materials they are made of.

3. Shredding and Pulping

In this step of the cardboard recycling process, shredding is done to break down the paper fibers into tiny pieces. Once the fibers are broken down, they are soaked in a mixture of water and chemicals to further break them down into a slurry substance (pulp). The pulp is then blended with fresh pulp made from wood chips to help it solidify and become firmer.

4. Filtering and De-Inking

In this stage, the pulp is taken through a series of filters that strain out any foreign materials present. These impurities include glue, tape, and strings. The slurry mixture is then taken into a machine where items like staples and plastics are removed through a centrifuge-like process.

During the de-inking process, the pulp is poured into a floatation device that is made of decolorization chemicals. The chemicals remove any ink or dye present in the pulp.

5. Finishing

In this final stage, the cleaned pulp is mixed with new production materials then dried. The pulp is then passed through a machine that presses out the excess fluid. The machine also facilitates the formation of linerboards and mediums.
