Following the successful completion of the transaction, Metso Paper will be able to deliver all core processes for modern pulp mills, including chemical pulping
lines, chemical recovery and power generation for pulp and paper production.
Unlike chemical pulping
processes that require chemicals to break wood down into its constituent fibres, mechanical pulping is largely a matter of grinding up the wood into basic components.
for chemical pulping
equipment and a recycling system.
With this process, 90% of the wood fiber is used, and it also delivers a marked improvement in efficiency over the chemical pulping
process employed to make competitive traditional freesheet from kraft pulp.

bond/67 gsm) sheet is produced by mechanically grinding wood into papermaking pulp instead of using the chemical pulping
process traditional for producing digital business papers.
During chemical pulping
, the kappa number was reduced by 22%-27% at the same alkali charge, or the alkali charge was reduced by 30 kg/ton of raw material, or the cooking time was reduced by up to 30%.
