Within a short time, UPM Shotton developed<br />
into one of the largest and most important<br />
suppliers of newsprint based on<br />
TMP and recovered fibre.<br />
In 2002, UPM established the “100%<br />
Shotton” Project. This means that, in<br />
future, Newsprint will be produced exclusively<br />
from domestic recovered fibre.<br />
A new, third recovered fibre system has<br />
been installed (see twogether issue<br />
18/04).<br />
