Supplemental and Recycled Fiber - Recycling Fiber Overview

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 recycled fiber sources and the processes that are used to turn that fiber into clean papermaking stock
