Supplemental and Recycled Fiber – Bale Handling

Wood fiber accounts for more than 90% of the raw material used in the production of paper and board products, and it can come from a variety of sources. These sources can be slushed virgin fiber that is produced onsite, market pulp from other pulp mills, or recycled/secondary fiber. This course will cover the storage and handling of market pulp and recycled fiber bales at papermaking facilities.

Key Questions

What is the difference between recycled paper and market pulp?
Market pulp is virgin fiber which has been screened and cleaned. Recycled, or recovered paper contains contaminants and typically has a lower water content, so it is more difficult to prepare for papermaking.

What are the two major classes of recycled paper?
Recycled paper can come from pre-consumer sources or post-consumer sources. The post consumer sources have more contamination.

How are bales “unpacked”?
Wire or straps holding bales together is usually cut all at once by putting the bale through a guillotine.

How should bales be stacked when they are stored?
Heavier, larger bales should be on the bottom of a stack. Avoid creating any stack of bales which could for any reason topple over.

What happens to the material in an recycled paper bale after it is unpacked?
Loose recycled paper is conveyed to a large mechanical pulper which breaks the paper into individual fibers.

Sample Video Transcript

The following equipment is commonly found at bale handling sites. Trucks and railcars, which deliver bales to the facility. Forklift and bale grab trucks, which transport and arrange the bales within the facility. A dewiring device, a blade or other device that is used to remove the baling wire in order to unpack and prepare the bales for repulping. One or more conveyors to transport the unpacked bales to the repulper. And one or more repulpers which receive the unpacked bales, add water and provide agitation to break up the pulp sheets or recycle fiber into individual fibers in a pulp suspension.
