The groundwood process results in more pulp and produces more paper than the kraft paper process, but the kraft process creates paper of a higher(prenominal) quality.

By most estimates, it takes approximately twenty-four 40 founding softwood and hardwood trees of six to eight inches in diameter to produce a ton of writing and printing paper when the Kraft process is used. Under the assumption that the groundwood process is twice as efficient, it would take about twelve of these same trees to create a ton of newsprint. In response to this environmental concern, most paper and pulp factories plant new trees to replace the ones they cut down for their paper making business. Of course, it takes several years for these newly implanted trees to reach the same size as the trees they are replacing. composing recycling has also helped reduce the number of...
