Very often, recycling and waste haulers use the term OCC in reference to cardboard. The term "cardboard" refers to post-use corrugated packaging material. Industry insiders know this product as Old Corrugated Cardboard/Containers (OCC).
Corrugated cardboard can easily be recognized by its multiple layer structure. The fluted or wavy middle layer between the sheets of paper keeps corrugated board light but gives it the strength it needs to carry products. Cardboard is a very useful packaging material and is used for many different types of products.
If OCC is kept dry and clean, recycling is straightforward as long as all non-paper materials such as bubble wrap, wood skids, plastic bags, plastic wrapping, and Styrofoam are removed.
