Appendix 3<br />
Clarification of facts and figures (Appendix 2 and paragraph 3.12)<br />
Production<br />
End product reel paper based on <strong>Sappi</strong> annual<br />
figures for <strong>2011</strong>.<br />
Energy<br />
Total internal use of electricity based on invoices.<br />
Air<br />
NO (total)<br />
gas turbine and boiler 6<br />
steam boilers 5 and 7<br />

mixed-air heaters<br />
Water<br />
As of 2008, groundwater consumption is recorded<br />
on the basis of calibrated measurements.<br />
Pollution units for <strong>2011</strong> are based on internal<br />
calculations.<br />
As of 2007, chloride volumes are analysed by<br />
accredited laboratories.<br />
Phosphate recorded while measured, according<br />
to measurement deposition.<br />
Waste (non-hazardous)<br />
Industrial waste consists of general waste<br />
from the production process, waste wood<br />
and sewage sludge.<br />
Re-usable waste consists of metal, wood<br />
(pallets, based on 15 kg per pallet) and paper<br />
waste (paper/board/cylinders).<br />
Not included are packaging materials such as<br />
barrels, big-bags and pallets (as these are returnable).<br />
Volumes of used oil are indicated in kilograms,<br />
based on conversion using the following<br />
formula: used oil (litres) x specific mass<br />
(0.9 kg/l).<br />

Comparison to BAT-Bref / IPPC /<br />
E-PRTR (paragraph 3.12)<br />
Emission levels for BOD5, COD, Total Suspended<br />
Solids, Total P and Total N have<br />
been calculated by dividing year load by<br />
net production (Net Saleable Product).<br />
Emission levels are listed in Appendix 2.<br />
Debit emission level has been calculated by<br />
dividing the purification plant waste water<br />
totals from Appendix 2 by Net Saleable<br />
Product.<br />
The emission level for electricity has been<br />
calculated by dividing Electricity, total consumption<br />
from Appendix 2 by Net Saleable<br />
Product.<br />
The emission level for process heat has<br />
been calculated by multiplying gas consumption<br />
from Appendix 2 by the calorific<br />
value of gas (0.03165 GJ/m 3 ) and dividing<br />
the outcome by Net Saleable Product.<br />
Gas supply emission level has been calculated<br />
by dividing the NO emission (in mg)<br />
from Appendix 2 by the calorific value of<br />
total gas consumption (gas consumption<br />
multiplied by calorific value of gas (31.65<br />
MJ/m 3 ).
