From OCC Bales to Recoverable Fiber This line sits between waste-cardboard collection and downstream fiber use. It does not simply compress boxes, and it is not a conventional paper machine. The job of the line is to make bulky OCC easier to handle, remove damaging contaminants, mechanically open the paper structure and deliver a more uniform recovered-fiber feedstock.
The term OCC refers to old corrugated containers: used corrugated shipping boxes and related packaging grades. In practice, incoming loads are rarely identical. Bale density, moisture, tape, labels, staples, plastic film and non-paper material can vary from one supplier to another. Those differences affect the equipment sequence far more than the name “cardboard” suggests.
Engineering boundary: the core line is a dry mechanical recovery system. When the final product must meet a paper mill, molded-fiber or specialty-fiber specification, the receiving process may still require screening, refining, wet preparation or other downstream treatment.
