4.7.6 Performance of Recycled Paper Products It is a popular misconception that the inclusion of recycled fiber is undesirable for any cellulosic product. While it is true that recycling can reduce the performance of some paper products, that reduction can be minimized by adopting these principles: - use previously recycled fiber in moderation the source of recycled fiber is of premium-grade (long fiber length) the source of recycled fiber is free of contaminants when designing paCkagingS that contain recycled fiber, use the recycled fiber In strategic areas of multi-component material (e.g. corrugated mediums). Properly done, well-engineered applications for recycled fiber can produce both tangible and intangible advantages for its user. Fiber Length: Recycling of paper products shortens the length of each paper fiber. As fiber length is reduced, so too are the number of bonding points between fibers; As the bonds are reduced, strength is reduced. However. with the introduction of new pulp technology, paper products may be recycled an infi- nite number of times. Shorter fibers may be extracted during papermaking and used in less structural applications including the manufacture of office or tissue papers. Contaminants: The quality of recycled paper and paperboard depends substan- tially upon the quality of the waste paper available to the recycling mill. The most frequently found contaminants are water insoluble adhesives, plastic film, plastic foam, rubber bands, metals, glass, asphalt, string and carbon paper. Plastic coated, laminated, and wet-strength papers and paperboard also cause production problems. All discarded waste paper cannot be recycled. in 1092, approximately 12 million of the 87 million tons of waste paper produced were unfit for recycling. The waste paper that is commingled with food waste becomes contaminated with odor and bacteria. In this instance, separation and collection are not econom- ical. Scrap or waste from container fabricating is a highly desirable source of recycled fiber because of its long fiber length and minimized exposure to non- cellulosic contaminants. 4.7.7 Recycling Aids for Cellulosic Materials Incorporation of the following will assist in further developing an outlet for your recyclable fiber: 30 Environmental Packaaina <strong>Guidelines</strong> Use water-based inks or FDNUSDA approved, Use plastic or paper tape and starch glues in place of staples and hot melt adhesives * Avoid plastic coatings or non-cellulosic materials; Design packages that are constructed of components that may be removed or separated prior to paper recycling (e.g. avoid free-rise foam-in-place), Avoid coatings or impregnating of corrugated, Avoid use of bleached kraWoyster white board Avoid cartons with urea-formaldehyde
4.7.8 <strong>Guidelines</strong> for Recycled Fiber Content Corrugated fiberboard packagings must be manufactured using postconsumer recycled fiber in quantities specified in Table 7. The total amount of recycled material required increases according to the date of board manufacture. The implementation schedule is provided below: Implementetlon Date Total Mlnlmum Recvcled Fiber I% welaht): 06/30/82 20% 06/30/93 30% 06/30/94 40 Yo 06/30/95 50 Yo Table 7. Required Postconsumer Contribution of Material Calculatlng Recycled Flber Content: Because corrugated mediums travel in the vertical as well as horizontal direction, take-up factors must be used when calcu- lating a materials combined basis weight to compensate for the additional material. Industry approximations for the take-up factors are shown below: Flute: Take-up Factor: A 1.55 B 1.35 C 1.43 Sample Calculatlon: The combination of 100% recycled mediums and interior liners wlth near-virgin outside liners produces a high-performance, corrugated product with a proportionately large amount of recycled fiber. An example of a high-performance board wlth a similarly high contribution from reclaimed material is illustrated in Table 8.
