FLEXO Magazine : Flexo Sustainable Spring 2008
FFTA Addresses Sustainability At Forum 2008 What is sustainability? How does one achieve it? Phyllis Kerr, Global Packaging, led a series of presentations geared toward providing the answers on Tuesday, April 29, in the Sustainability Session at FFTA's 2008 Forum in Dallas, TX. FTA's director of EHS services and special projects, Doreen M. Monteleone, Ph.D., kicked things off by updating attendees on the activities of the Sustainable Green Printing (SGP) Partnership (see page 6 for complete details). "Sustainability is actually very personal and very individualis- tic," said Debbra Johnson, DuPont Packaging Graphics. "There isn't one right answer for sustainability-there are many right answers." She added. Your journey to a more sustainable business is dictated by where you are today." Johnson revealed preliminary results of a study into flexography's current sustainability factor. Results were measured in mega-joules of non-renewable energy units and kilograms of greenhouse gases. The study is currently under peer review, inhibiting publication of the data. Kerr Black Belardo Collins www.flexomag.com In The News Martin Spatz, Sun Chemical Corp., reviewed existing sustain- ability options for inks. He noted that water-based inks are 95 percent free ofVOCs (volatile organic compounds). Organic sol- vents have 50 percent VOCs at application, and UV/EB inks are VOC-free. He reminded attendees that "dry inks of less than 1 percent are not factored into compostability." Most ink formula- tions also avoid the use of heavy metals. There are a number of organic compounds already used in inks. They include cellulose (nitro-, acetate, propionate), modified rosin, shellac, proteins, starches, esterified fatty acids and ethyl alcohol. Pliant Corp.'s Dan Collins brought up sustainable substrates. He discussed various bio-based films, such as starch, cellophane, cellulose film, PLA (polylactic acid), and PHA (polyhydroxyalkano- ates). In addition, there are existing films that can be used to reduce waste and material consumption, including printable seal- ants, multilayer films, reduced gauge sealant layers, shrink film and stretch wrap. Frank Belardo, Phoenix Environmental Technology, spoke on solvent recovery and recycling. He stated that recycling was less costly than the disposal and purchase of new solvent. Modern equipment can recover between 70 and 95 percent of solvent. Many service companies will handle the task on-site. "Most corrugated items when loaded in a truck will never ex- ceed the legal gross vehicle weight," said Charlie Black, Smurfit- Stone Container Corp., in his presentation on cube utilization. He told attendees to "consider logistics as part of sustainability." That includes minimizing shipments. He asked his fellow print- ers/converters to "strive to use as much of the trailer as possible." This task, he notes, is easier said than done. "As manufacturing moves overseas and more plants close, it increases the distance between your customers." Spatz Johnson SPRING Sustainable FLEXO - 2008
