For those paper mills producing more than one grade of paper <strong>and</strong>/or market pulp it is<br />
necessary to allocate inputs <strong>and</strong> outputs to the different paper grades or pulp. Mill staff<br />
who filled in the questionnaire have made the allocation according to causality.<br />
Data has been collected relating to the following key non-fibre inputs to the pulp <strong>and</strong><br />
papermaking processes:<br />
• Sulphuric acid (H2SO4)<br />
• Sodium hydroxide (NaOH)<br />
• Oxygen (O2)<br />
• Hydrogen peroxide (H2O2)<br />
• Sodium Chlorate (NaClO3)<br />
• Calcium oxide (CaO)<br />
• Chlorine dioxide (ClO2)<br />
• Sodium bisulphite (NaHSO3)<br />
• Ground calcium carbonate (GCC)<br />
• Precipitated calcium carbonate (PCC) – purchased<br />
• Clay<br />
• Wet strength agent<br />
• Dry strength agent<br />
• Synthetic binders (latex)<br />
• Binders (other than latex)<br />
• Starch – maize<br />
• Starch – potato<br />
• Starch – corn/wheat<br />
• Starch – cationic<br />
• Starch - other<br />
The total mass of other non-fibre inputs not listed above is below 1% of the paper weight.<br />
In compliance with the defined cut-off criteria, these other non-fibre inputs have<br />
there<strong>for</strong>e been omitted from the study as insignificant.<br />
