Currently, cellulose-based fibers can only be recycled 6-8 times, after which the fiber length and properties are too significantly impacted for any further reuse. Technologies are therefore required to enhance the fibers’ recycling potential. The technologies must not add virgin fibers at each recycling stage. Potential solutions include synthetic fibers to aid in recovering structural integrity lost in repulping; coatings to provide strengthening end results; and chemical technologies that minimize damage to the fibers during repulping. The primary function of packaging must be maintained.
