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. In the "recycled" fiber category, the most difficult source to process is post-consumer waste. This fiber arrives at the mill contaminated with a variety of undesirable materials, also called rejects. In this course, we will identify the sources of rejects in a recycled fiber facility, identify the types of rejects or contaminants generated, and discuss how they are subsequently processed, or "handled."
