Page 158: "about 164,000 cubic metres of water used, equivalent to approximately 3% of total withdrawal, are obtained from the waste water treatment of its production processes"

There is a discrepancy here. The table on page 157 lists water withdrawal as 8,310,000 cubic metres. 164,000 as a percentage of 8,310,000 is 1.97%. I have used the calculated percentage rather than the reported one.
