called Nordic group.70% of the annualworld sales of pulp is met by these countries,in which Canada alone has a share of 25% in the global market.
Bleached CTMP(Chemi-thermo mechanical pulp) is imported into India in large quantities.Only 4 paper mills in India have the facilities to make CTMP,
while other mills have resorted to expensive and environmentally
pollutant pulping methods like craft
pulp / semi-chemical pulp, chemical pulp etc.
materials contain cellulose fibres, which are bound together
with a glue-like binder called lignin.The main task in the
manufacture of CTMP pulp is to separate the Cellulosic fibres
from lignin by Pressurized Refiner or De-fibrator.In the
refiner system, two disc- shaped rough surfaces rotate in
opposite direction.Due to this high speed rotation in opposite
direction, the fibres are torn apart. Subsequently, the
pulp can be dried in a flash tube drier and baled / screened,
thickened & sheeted, to supply market pulp to the paper
