Paper-Recycling System: Part 8

Second, waste paper refers to the general, gross waste paper output from consumption and manufacturing processes. Waste paper fiber potential or reuse fiber potential means the part of the waste paper which could be collected for recycling as raw material for base paper production (i.e., gross output excluding long-term products and sanitary papers disposed with sewage). Third, recycled fiber or reuse fiber is the net fiber output from re-pulping to be used in the base stock furnish. The composition of recycled fiber depends on the re-pulping technologies (i.e., removal of non-fibrous materials). Re-pulping takes waste paper (raw material) as input. Fiber balance is used as a general name for the mass balance of the paper cycle.

Waste paper as part of the base paper and board production (1% to 5%) is recycled within the paper mill and, therefore, is not part of the external waste management and recycling process. This category of waste paper originates in different trimming and finishing steps in the base paper and board production lines. It is re-pulped and reused as feed stock for paper and board machines - often for the same machine it originally came from. This is normal practice and has no effect on the fiber balance of the recycling.
