Post-Consumer Recycled Fiber

Processing Requirement

Pulp mills treat these inputs using deinking and cleaning stages to remove contaminants like adhesives, coatings, or non-paper inclusions. A higher percentage of this feedstock typically demands more aggressive cleaning cycles which can degrade the length of the individual strands. Strength tests on the resulting sheet demonstrate the trade-off between recycled content and mechanical integrity for high-speed folding or packaging applications.

Suppliers must balance these inputs against virgin pulp ratios to meet physical specifications for stiffness or burst resistance.

Certification Logic

Third party auditors validate the quantity of recovered material by tracking mass balance data throughout the production run. This verification process relies on accurate reporting of output weights versus input volumes to prevent the inflation of environmental claims. Auditors check that the facility records distinguish between pre-consumer waste from trimming operations and the defined feedstock from actual domestic or commercial usage.

Final paper products gain legitimacy in global markets only when the audit trail proves the material arrived through established collection networks rather than internal floor sweepings.
