Abstract |
Cleaner, cheaper and cleverer will be the guiding philosophy for chemical pulpng and bleaching in the '90s. Tried and tested ways of pulping are being tweaked and refined to make them more compatible with the stricter environmental demands which are sure to be imposed during the decade. And with the prospect of soaring fuel costs, squeezing the last drop of energy out of every part of the process will take on an added importance. Perhaps the most useful development for the kraft pulp industry has been the Chemrec process, which Kamyr is marketing. |
