        Sustainability

        Sustainability and the Modern Printer

        September 6, 2016

        by Brittany Willes, editor, PostPress
        As part of its sustainability efforts, Posty Cards provides six charging stations for a total of 12EV charging stations as part of the KCP&L Clean Charge Network.

        For anyone who has been paying the slightest bit of attention the last few years, environmentalism has become THE hot-button issue. Sustainability is the new sexy, and too often the print and binding industry has received a disproportionate amount of criticism for being environmentally-unfriendly. Print is wasteful, it kills too many trees, it’s outdated and consumers don’t want it anymore – all arguments which industry insiders know to be patently untrue. While print has been experiencing a major resurgence, more and more companies are developing “green” agendas in order to avoid unnecessary waste. However, even companies with dedicated environmental programs need additional guidance when it comes to creating truly green, sustainable practices. As a result, they have begun reaching out to, and partnering with, industry experts in order to learn more about sustainability.

        For instance, the Foil & Specialty Effects Association (FSEA), Topeka, Kansas, recently joined with the Sustainable Green Printing Partnership (SGP), Sayville, New York, as a Resource Partner for the SGP community. Resource Partners act as sustainability subject matter experts, equipping members of the printing industry with the most current information regarding sustainable methods. The SGP Resource Partners “include a diverse group of organizations, from industry trade associations to educational institutions and NGOs, all striving to provide information and resources to help create a more sustainable print industry,” stated SGP Board Member Doreen Monteleone.

        “The FSEA believes promoting sustainable and environmentally-friendly practices is very important as an association in the graphic arts industry,” stated FSEA Executive Director Jeff Peterson. “Becoming more involved and supporting SGP will help us with this goal and provide guidelines to share with our membership.”

        “What makes SGP unique is that it is a true sustainability program for the printing industry and goes beyond just environmental compliance or a single attribute, like a chain of custody paper program,” explained Monteleone, who works for the Flexographic Technical Association and RadTech International North America promoting SGP and sustainability in the print supply chain. “The SGP program is comprehensive, encompassing sustainable processes and procedures throughout the entire printing facility, not just the pressroom.”

        Facilities often make misleading claims about being a green facility, which is considered greenwashing. An example might be a company stating that it is green because it has certified paper, but it isn’t using best practices to handle waste. Many times this type of greenwashing is unintentional, though not always. In order to help companies avoid such misleading statements, the SGP provides for third-party validation of comprehensive sustainability efforts that cover the entire facility, from what happens in purchasing through shipping and even the cafeteria and the surrounding property.

        SGP grew out of the printing industry’s need to prove it was sustainable and the need to understand what it takes to be a sustainable printer. In 2007, according to Monteleone, “Marci Kinter of SGIA, Gary Jones of PIA, George Fuchs of NAPIM and myself representing FTA learned that we were all getting calls from our respective members asking what sustainability was and how to prove they’re sustainable. Printers were being asked about their sustainability programs by their buyers (brands and retailers) who were striving to meet consumer demands to be more sustainable.”

        Back then, criteria defining a sustainable printer had yet to be established. Monteleone and her colleagues agreed they needed to help members by first defining what constituted a sustainable printer and then creating a certification program to validate those efforts. “We felt that to be credible there needed to be a separate, independent certification entity. The program needed to be inclusive of all print processes in the United States and Canada, and it needed to be transparent and publicly vetted,” explained Monteleone. “Using our past experiences working on stakeholder groups with US EPA, we formed the SGP stakeholder group, which included printers from all processes, suppliers, print buyers, regulatory agencies, NGOs and association representatives. With some give and take, we eventually came to a consensus as to what criteria needed to be met to be certified as a SGP Printer. After a lot of hard work and out of the joint efforts of the printing industry, SGP certified the first printers in 2008.”

        Since then, interest in sustainable standards has only grown, with more and more companies researching ways to create a sustainable future. Posty Cards, Kansas City, Missouri, is one such company. Following the complete renovation and expansion of its LEED Platinum headquarters manufacturing plant in 2011, Posty Cards was introduced to former SGP Board Member Martine Padilla. “Martine helped us understand how SGP certification might fit into our overall sustainability strategy,” remarked Erick Jessee, Posty Cards’ president. “In that discussion, we realized that SGP certification dovetailed perfectly with our goal to third-party certify the sustainability of our entire operation.”

        For Posty Cards, sustainability always has been a core value of the business. When Jessee joined the company, he started several big initiatives designed to move Posty Cards’ entire operation toward a more sustainable future. “Part of that strategy is to ‘walk the talk’ with integrity,” Jessee said. “We believe it is important to show integrity and transparency in our sustainability practices.” Through third-party certification, Posty Cards is able to give its customers, employees and other stakeholders confidence that it continues to abide by sustainable standards. SGP certification is a significant part of that.

        In order to become SGP-certified, facilities must first apply and then schedule an onsite audit within a year of the original application date. A trained SGP auditor spends a full day touring the facility, reviewing documents and interviewing employees to ensure the facility is meeting the SGP criteria that establish the best practices, including a sustainability management system that must be followed in order to achieve certification. The facility also must be in compliance with all applicable environmental, health, safety and labor laws and have designated a continuous improvement project. If needed, the facility will have the opportunity to make corrective actions if it does not meet the criteria. Once the facility passes its SGP audit, it becomes certified. Each year, it must report on its continuous improvement project and establish new goals and objectives for the upcoming year. Every other year, there is an onsite audit. SGP is developing a more simplified recertification process for facilities that have already been through one cycle and have not had any issues.

        Becoming SGP-certified validates a facility’s sustainability efforts. There is no other program in the US or Canada which covers all print processes and has the support of major printing organizations. Over the years, Monteleone remarked that she has encountered many facilities that claim to be green and sustainable due to environmental programs they had initiated. Some of those facilities even have won awards for their noteworthy programs. However, “SGP goes way beyond one area or one attribute and it is not just an environmental program. It includes health and safety. SGP takes a holistic approach,” she said. “A sustainable operation can’t just be ‘green’ in the pressroom and ignore the rest of the facility and its employees.”

        For businesses like Posty Cards, “SGP certification is an important component of third-party certifying the sustainability of our entire operation,” explained Emily Street, Posty Cards sustainability coordinator. “Through LEED certification, we certify how our headquarters and manufacturing plant was designed and constructed and its operational efficiency. Green-e certification certifies our 100-percent green energy use. Chain-of-custody forestry certification certifies our supply chain and the materials used in our products. SGP certification covers everything in between, including how to run a printing business sustainably.”

        Not only does SGP certify how sustainably Posty Cards runs its operation, it provides its stakeholders peace of mind that the company truly “walks the talk.” SGP also provides structure and a framework for mainstreaming Posty Cards’ sustainability program. The SGP certification helps Posty Cards track such metrics as energy and water usage, waste disposal and VOC emissions and helps highlight opportunities for improvement. “One of the biggest things we’ve learned is that sustainability is a journey, not a destination,” said Street. “No matter how far down the road of sustainability we’ve gone, there is always more to do. There is always more to be reaching for, another goal to accomplish.” SGP promotes that continuous improvement orientation with required annual continuous improvement projects.

        Part of SGP’s holistic approach of continuous improvement is its focus on education and community participation, which the SGP promotes via webinars, an annual conference, referral to industry experts and SGP auditors who review and help facilities gain fresh perspective of sustainability practices. Additionally, the founding associations, along with other SGP Resource Partners like FSEA and RadTech, provide assistance to the printing industry to help them learn about sustainable best practices and obtain SGP certification.

        In addition to educational benefits, those who achieve certification are promoted on the SGP website, where they also obtain market advantage. “Personally, I’ve had large print buyers wanting a more sustainable supply chain contact me and ask about SGP and where to find the list of certified printers,” said Monteleone. “We now have New York state preferencing SGP printers for the state procurement of printed materials, and Wisconsin recognizes SGP certified printers for entry into its Green Tier program.”

        Although most members are printers, SGP criteria also accommodates binders and finishers. According to Monteleone, “As print buyers become more educated about SGP, any links in the supply chain that are certified will have the market advantage. Plus, like printers, these facilities will become enlightened about areas where they can make headway in becoming more sustainable which, as we know, will improve the bottom line.” In a nutshell, sustainability simply makes for good business practices. SGP’s goal is that print buyers will look toward SGP-certified facilities as the gold standard of sustainability in printing. To that end, the organization has maintained a presence at key venues, such as Sustainable Brands and the Sustainable Purchasing Leadership Council, with the goal of educating the print buying community.

        Beyond differentiating a printer in the competitive marketplace, instituting sustainable practices creates real cost and resource savings. Statistics from annual reports of SGP printers include energy savings of $25,000 annually, waste reduction of 850,000lbs, water reduction of 145,000 gallons and greenhouse gas emission reductions of almost 2.5 tons. Because of SGP’s holistic nature, it forces companies to look into areas they’ve not explored before to improve their sustainability footprint. It can be a real eye-opener.

        “We believe sustainable print operations are the key to success,” said Street, “now and in the future as more buyers become concerned about the environmental impact of their purchases and look more deeply at the sustainability of their supply chain. Third party certification gives us credibility with stakeholders, certifies that we are the real deal and ensures that we maintain ongoing discipline in our organization.” Like many manufacturers, Posty Cards believes it has a responsibility to its customers, community and employees to minimize its impact on the environment. In keeping with this corporate philosophy, all of its cards are printed with soy ink and printed on recycled or FSC-certified paper. However, the company also recognizes that using green materials is only part of the picture. “We would recommend SGP certification to other companies in the printing industry pursuing sustainability in their operation. SGP is a great tool for developing and maintaining a sustainable operation,” Street asserted.

        “We’re committed to making our business as sustainable as possible,” stated Jessee. “As a manufacturer, we’re uniquely positioned to continuously improve the efficiency of our operation and the sustainability of our products. With that comes a bigger responsibility to minimize our impact on the environment.”

        Companies of all print processes, big and small, in the United States and Canada have become SGP-certified. As Monteleone noted, the SGP not only encourages printers to become certified because of the benefits to their operations, it also educates print buyers about using SGP certified printers to ensure a more sustainable supply chain. SGP was created by the printing industry, for the printing industry. There is no better set of criteria that define sustainability for the printing industry. If retailers and brands are seeking a more sustainable supply chain, they should be looking to use SGP-certified printers.

        New Study Reveals False Slogans

        February 13, 2016

        PostPress

        A new study from Two Sides North America, Chicago, Illinois, outlines key facts on why paperless initiatives do not save trees.

        Findings suggest that using less paper and wood products actually increases the risk of forest loss because the loss of market would increase the likelihood of the land being used for urban development or agriculture. The study was conducted by Dovetail Partners, an environmental think-tank specializing in forestry research and analysis.

        Two Sides Launches Global Anti-Greenwash Initiative

        April 13, 2015

        PostPress

        New research commissioned by the international nonprofit organization Two Sides, Chicago, Illinois, has revealed that major global corporations still are using inaccurate and misleading environmental claims to encourage consumers to “go paperless” and switch from paper-based to digital communication, despite legislation being introduced by advertising standards authorities to protect the consumer from being misled.

        The survey, undertaken in February 2015, showed that in the UK, there is a significant proportion of banks, utilities and telecoms making false environmental claims. Research in the US shows a similar picture with half of the leading Fortune 500 companies in those sectors doing the same.

        Two Sides will be engaging with companies in Europe, the USA, Canada, South America, South Africa and Australia, that have either reneged on undertakings to stop using misleading environmental claims or are now again claiming that switching to online billing and communication is better for the environment without supplying verifiable supporting evidence.

        Green Button Technology in Print Finishing

        March 25, 2015

        by Al Boese, Bindrite Dealers Association

        Beginning in the mid-1990s, digital technology changed the world and the printing industry along with it. This was a revolution indeed, as the devices employed by printers – while improved over time – had remained substantially unchanged over centuries. The machines used by the printing industry, beginning with setting cold and hot type, the Gutenberg Letter Press and crude guillotine paper cutters were classically analog and performed yeoman-like service for five hundred years (give or take a few).

        In the late 20th century, however, the digital revolution tore down everything within a couple of decades. Cold type setters in 1980 were working a Compugraphic phototypesetter in 1990 or not working at all. Darkroom film strippers in 1980 were learning color management software in 2000.

        Most people date the beginning of this metamorphosis to the introduction of digital image setters, a disruptive technology that changed prepress forever. Because these devices could go directly from artwork file to press, they eliminated facilities, darkrooms, cameras and stripping.

        In the late 20th century, prepress technology made the jump to imaging directly to plates already installed on the press – skipping the film stage altogether. This was the beginning of what I call the Green Button Revolution.

        What is the green button revolution? Basically, it is the next stage of automation in digital printing, and it now is beginning to affect all phases of paper handling, binding, protecting and the other print finishing processes. Green button means that worker intervention is minimized; in its most ideal form, the operator merely needs to load the machine and press a button (which most often is green). The end product comes out the other end.

        In the late 20th century, the green button revolution already was manifesting itself in other ways. Office photocopiers were increasingly deploying touchpad controls. Along the way, these machines were becoming multifunctional in ways that the old office mimeograph user could not have imagined. Options such as duplex printing, reduction or enlargement, print orientation, collating and stapling became standard. It all was integrated with and enabled by desktop publishing technology and distributed far and wide by networking systems. Simultaneously, electrostatic and inkjet printers propelled digital printing into the large format world.

        But, where did this leave print finishing, the overlooked stepchild of the printing industry? Print finishing was an analog world from the beginning and has remained so almost without exception until a few years ago. The shining exception was the Fast Back Thermal Strip Binding Process developed and introduced by Powis Parker in the mid-1990s. That product was a glorious success owing to several factors, including aesthetics (the finished bound book looked great), operator simplicity, versatility and modern industrial design. It was a pioneer in the green button revolution.

        It was not until early 2000 when the next green button print finishing machine came along – the ALM 3220, a fully automatic laminator. Designed by FujiPla of Japan and introduced by DryLam, the ALM 3220 changed the way the industry thought about lamination and began the onset of an ever growing parade of green button finishing equipment.

        Supporting statistics

        Speaking at the BindRite 2014 annual meeting, National Print Owners Association (NPOA) president John Stewart made a compelling case for more automation in post-print processes across the board. Stewart presented statistics derived from NPOA’s 2014-2015 Financial Benchmarking Study, which included such fundamentals as annual sales, cost of goods and payroll. Notable among the trends was Stewart’s conclusion that labor costs are rising significantly faster than other shop expenditures. A key chart showed labor expenditures as a percentage of all costs climbing from 24.3 percent in 1983 to 32.5 percent in 2011.

        That leap establishes labor costs as the single greatest category of business expense, overtaking overhead as the greatest drag on profits. In fact, with overhead and cost of sales remaining relatively stable over the 30-year period, the uptick in labor costs comes almost directly out of owner’s compensation.

        These findings account to no small degree for a surge in sales of automated finishing equipment. The deployment of green button technology generally results in immediate improvements in productivity. Time is saved because the user interface is intuitive and simple. Many standard jobs are pre-programmed, and custom work can be stored for future use. Job setup is simple, swift and precise. Machine operation during a job run is automatic, freeing an operator to prepare the material for the next job or other multitasking activity. Likewise, material is conserved because makeready essentially is eliminated, and a perfect result usually is achieved on the first sheet or book. Green button technology is alive and flourishing, with even more potential for the future.

        • Digital Print Challenges the Binding and Finishing Process

        Finishing Processes Not a Barrier to Recyclability

        October 13, 2013

        by Victor Bell, Environmental Packaging International

        There’s growing interest among many of the largest brand owners, retailers and governments in promoting environmental best practices. Some of these new initiatives impact the finishing industry.

        Paper-based packaging remains the most commonly used packaging material in the world – contributing nearly 40 million tons to the municipal solid waste stream in the US. Some of the common treatments applied to packaging to enhance its graphic appeal, such as hot foil stamping, laminating and metalized paper, are perceived to present challenges to local recycling processes, deeming them unacceptable. But, that’s not necessarily the case.

        Is foil finished … or recyclable?

        From posters and wrapping paper to greeting cards and cosmetics packaging, communities within the US approach paper embellishments differently when it comes to recycling. While some community recycling programs accept aluminum-bearing paper, others don’t accept them because of concerns about the potential appearance of aluminum particles in the recycled content paper or the difficulty in repulping fibers.

        When it comes to the recyclability of these materials, the bottom line is the bottom line. And while some programs fear mixing foil in the recycling stream may diminish the value of the finished paper product, a study conducted by Smithers Pira (Pira International) confirms the recyclability and repulpability of paper products decorated by both the traditional hot stamp and new cold foil processes.

        Education is key

        To improve recycling rates of paper and packaging with metalized effects, more information is needed about the mechanics of the different treatment processes. For example, subtle distinctions between all of the techniques – especially between metalized paper and foil-laminated paper – can have a big impact on the collection, sorting and recyclability of packaging.

        Since these differences are not well understood, reports such as the Sustainable Packaging Coalition’s “Closing the Loop: Design for Recovery Guidelines for Paper Packaging”, published in 2011, provide guidance to drive more informed decisions before putting packaging on the market.

        Avoid consumer confusion

        It’s not only a lack of understanding among community recycling programs or the design aspects of the packaging that impact the ways in which finished papers are disposed. Consumer behavior also can pose barriers.

        Because of various treatment by the recycling facilities – or outright avoidance of metalized papers altogether – consumers are left wondering what curbside container to use. That’s where brand owners, package designers and printers can help – by accurately labeling how these materials can be collected and recycled.

        While the Federal Trade Commission’s “Green Guides” are designed to prevent deceptive environmental claims, it also can be used to promote a clearer understanding among consumers about how to treat their waste.

        For example, packaging must include qualifying text unless recycling programs for it are available to “a substantial majority” (at least 60 percent of either consumers or communities where it is sold). Since less than 60 percent of communities take paper with foil, one of the following types of qualifying text must be used:

        • If recycling programs for the packaging are available to a “significant percentage” of consumers or communities where it is sold, then qualifying text such as “Package may not be recyclable in your area” must be included.
        • If recycling programs for the packaging are available to “less than a significant percentage” of consumers or communities where it is sold, the package must include a statement such as “Product is recyclable only in the few communities that have recycling programs.”

        Finally, the Möbius Loop recycle symbol only should be printed on packaging if it includes text stating “recyclable” or includes the percentage of recycled content. Otherwise, it constitutes a claim that the packaging (and product) are made of 100 percent recycled materials and are universally recyclable, which is deceptive unless the claim can be substantiated.

        The impact of EPR

        As Extended Producer Responsibility (EPR) expands its reach across Europe and beyond, the responsibility for packaging and printed paper recycling and disposal is increasingly shifting from local governments to private industry. By requiring producers to pay for post-consumer waste created by their products, EPR creates an incentive for producers to make packaging that is less wasteful.

        While EPR is designed to encourage companies in their design and choice of materials, in certain countries this means penalizing them for ignoring recyclability. France, for example, has implemented disrupter fees, or “eco-modulation fees,” for those who contaminate the recycling stream. With this approach, producers are charged more for using material combinations that negatively affect the recycling system, such as putting a lot of plastic in paper envelopes or using a ceramic top on a glass bottle. In France, a PET bottle with at least one aluminum component, an aluminized label or aluminum pigments is considered a disruptor and is assessed a 50-percent higher fee.

        When it comes to producing packaging that is designed for recyclability, it’s important to consider current recycling infrastructures, technologies and awareness during the design and manufacturing stages of development to optimize its useful life – at its end of life.

        New Technology for Three Printing Elements

        July 13, 2013

        by Anderson & Vreeland

        The flexo industry has experienced a recent profusion of technological innovation, affecting every step of the flexographic printing process. Jessica Harkins, technologies manager at Anderson & Vreeland, shared how three key printing elements – prepress, press room and platemaking – have been revolutionized by new technologies in the past few years.

        Prepress

        Then: Analog was king and proofs were made using products like Kodak Approval and Dupont’s Digital Chromaline. Inkjet had yet to come into play across the board, being used mostly for content proofing.

        Now: We have seen the future and it is inkjet. With developments in inkjet technology, coupled with measuring instruments, consistent and exact color predictions are easier than ever. “Proofing types have changed in equipment, in quality and in ability to match color,” Harkins said.

        Ditch the FPO servers – computer hardware and software has developed in leaps and bounds. Systems now have the ability to handle full design files. New software has simplified complex projects and helped increase automation and speed. Of course, designs have become more complex, thereby increasing file size.

        Press Room

        Then: Densitometers were around but not yet ubiquitous in the press room. J.I.T. was new but not yet common. There also were fewer CPCs and fewer methods of waste measuring.

        Now: Tracking, minimizing waste and maximizing environmental accountability – the press room has changed to accommodate cost controls and environmental sustainability. The new eco-awareness has been driven, in part, by consumer product companies expecting accountability from flexo suppliers. They are measuring cost, performance and eco-awareness.

        Quality control devices are better than ever, and press room operators now can track pretty much everything, although there’s definitely been a learning curve, Harkins said. “Not everyone has jumped on board, but once educated, most see the value in taking the time to measure, track and analyze.”

        Platemaking

        Then: Digital platemaking was new technology and expensive, pretty much reserved for larger outfits that could afford the outlay.

        Now: Digital is now the norm and means the capacity to print a larger tonal range. A new option that’s just made it to North America, Harkins noted, is inkjetting specialty inks directly onto plate materials laminated with a primer sheet – the ink solidifies and creates a negative.

        Environmental sensitivity has made it to platemaking as well. Eco-friendly solvents and photopolymers that are washable with water and produce a low odor are used instead of the “old-school” harsh and environmentally damaging chemical solvents.

        As package designs and substrates become more complex and brand owners demand originality to distinguish and protect their products, look for even more technological innovations that will take flexo printing further into the digital age.

        Anderson & Vreeland provides customers with a solutions-based approach to business by offering innovative material and technological solutions in the flexographic industry. A nationwide staff of technical representatives is thoroughly knowledgeable about digital imaging and the fine point of flexo.

        ecoGenesis Allows RF Welding of Green Materials

        August 21, 2011

        by: Amy Bauer

        A proprietary radio frequency (RF) welding technology from Genesis Plastics Welding is expanding the capabilities of traditional RF welding machines, allowing them to bond a wider array of materials, including many considered more “green,” or ecologically friendly.

        The technology, called ecoGenesis™, has been in development for more than 20 years, according to Tom Ryder, Genesis president and chief executive officer. Today, the company applies ecoGenesis to products produced in its contract welding facility in Fortville, IN, and licenses the technology to other plastics manufacturing companies.

        ecoGenesis is a system that “bolts on” to existing RF welding machinery and, using standard settings and no additives to the materials being welded, provides a strong bond between materials that previously weren’t candidates for RF welding, such as polyethylene, polypropylene, polyester, nylon and bioplastic. These phthalate-free materials are options to polyvinylchloride (PVC), which has become the subject of concern among consumer and health groups.

        RF Then and Now

        Traditional RF welding works by passing radio frequency waves through materials, exciting the molecules so that they heat up and meld together from the inside out; thus, creating a strong bond. Ryder described it as similar to a potato heating in a microwave, cooking from the inside out. While RF welding has been used extensively with PVC and polyurethane (PU), Ryder said one of the biggest downsides to RF welding has been its limitation primarily to such polar materials – those with molecules that because of their positive and negative poles attract or repel one another. Nonpolar materials are made up of molecules without positive and negative poles. Those materials – like polyethylene, polypropylene, polyester, nylon and bioplastic – are candidates for ecoGenesis RF welding.

        As described in a white paper paid for by Genesis Plastics Welding and The Dow Chemical Company, “Prior RF welding art allowed for only a few polymer films – like polyvinylchloride (PVC) and polyurethane (PU) – as candidates for a good RF weld.” Technical consultant OmniTech International was hired to evaluate ecoGenesis and “confirmed that films, copolymer films and fabrics with low dielectric factors (DLF) can efficiently and effectively be RF welded with ecoGenesis – without the aid of coatings, adhesives or other costly treatments.”

        Other methods for bonding nonpolar materials include using heat sealing, impulse welding, adhesives or materials with polar additives, such as EVA, said Ryder, noting that each has its own drawbacks, whether limited dimensions to the weld or added materials costs. “There are other methods, they’re just not as efficient or cost-effective as ecoGenesis,” he said. By eliminating the need for expensive heat seal additives and allowing the substitution of lower-cost raw materials, ecoGenesis helps to keep costs down, the white paper notes.

        Proving the Technology

        While the company declines to disclose many specifics of the ecoGenesis technology, or how many companies currently are licensing it, Ryder says seeing has been believing for Genesis Plastics Welding customers. “The real gurus of radio frequency welding are very skeptical,” he said. “Because it’s proprietary technology and we’re not able to disclose or just hand over the technology to anybody without a license, to be honest with you, they don’t believe us.”

        He says one of the best ways to convince those considering the technology has been by taking materials a company has tried unsuccessfully to RF weld, creating the weld using the ecoGenesis technology and sending the finished product back to them. If companies still express disbelief, Genesis offers a visit to the company’s facility for a nonconfidential demonstration. “We’ll have the technology hidden, and they come in, they see it’s a standard RF machine and none of the settings are changed,” he described. “And when they witness us welding it, they become believers.”

        Technical Specifications

        Ryder said the ecoGenesis technology can be added to any standard RF machine, large or small, as easily as a tool can be changed, allowing a shop to switch from welding PVC and polyurethane in the morning to welding nonpolar materials like polyethylene and polypropylene in the afternoon. Because it is an addition to existing machinery, Ryder said, companies are saved a large investment in capital expenses.

        “The technology lasts for tens of thousands of cycles. It doesn’t leave any residues. It doesn’t require any additives in the materials that you’re welding. And it can be taken on and off the machines,” Ryder described.

        Operating ecoGenesis doesn’t require an extensive amount of training, he said. Genesis coaches a company’s setup technicians. “If a company has technicians that are very familiar with using RF welding, they’ll actually find it very simple to use,” Ryder said. Those operating the machine in many cases may not even realize it’s there. “It changes nothing with the day-to-day pushing the buttons and making the product,” he said.

        Because Genesis Plastics Welding operates its own contract welding facility, which includes the ecoGenesis process among 24 different RF systems, it has been able to develop products for some companies or do pilot runs, testing and analysis before licensing ecoGenesis to them.

        Demand Grows for PVC-free

        The push toward PVC and polyurethane alternatives is being driven in large part by public concerns about adverse health effects of phthalate plasticizers in some PVCs, which increase the material’s flexibility but also may leach out. Burning of PVC also releases harmful toxins, so disposal is a concern.

        The Consumer Product Safety Improvement Act of 2008 (CPSIA) limits the amount of phthalates allowed in children’s products, and California’s Proposition 65 requires warnings on consumer products containing any of hundreds of chemicals that the state lists as known cancer- or birth-defect-causing agents. PVC-free and phthalate-free labels are becoming selling points for consumer products.

        Ryder said large retailers are moving to reduce or eliminate PVC in their inventories. “Right now, companies like Staples, for example, are putting out press that says they want to be PVC-free in 2012 and 2013,” he said. “Wal-Mart’s giving better grades for PVC-free product. Target’s doing the same. Companies on the retail end are pushing that with their suppliers,” he said, noting that businesses are looking for solutions now rather than waiting to see if more regulations will follow.

        In the case of loose leaf binders, buyers may increasingly be looking for phthalate-free binder covers and sleeves and sheet protectors, while still expecting a traditional binder look and feel. “And from a packaging standpoint, if you have a cloth product that’s not PVC and you add PVC packaging to it, you’re bringing your opportunity down with those retailers,” Ryder said.

        Cooperative Marketing

        In addition to the growing “green” buzz in the marketplace, Genesis Plastics Welding is incorporating a push strategy in rolling out ecoGenesis by working with materials suppliers looking for ways to use and market their materials to manufacturers. The Dow Chemical Company, which helped pay for the white paper on ecoGenesis, is one example. Another is a company called PolyOne GLS Thermoplastic Elastomers, with which Genesis recently partnered in welding phthalate-free medical devices and marketing the achievement.

        “We’ve done a lot of networking with materials suppliers, because they’re the ones trying to push their materials to the manufacturers,” Ryder described, “and they’ve helped us in that sales process.”

        Future of ecoGenesis

        While the applications of ecoGenesis will continue to grow as new materials emerge, Ryder said he doesn’t see traditional RF-welded materials disappearing. “PVC is a good material. I don’t think it will totally go away,” he said. But he noted that the potential of some materials, such as bioplastics, has barely been tapped. “There’s new materials coming out every day,” he said. “And being able to switch from one to the other I think is a good opportunity because there may not always be a better advantage with polar materials every time.”

        “ecoGenesis just provides people more opportunities and more options to choose from. It’s taking the RF technology and advancing its opportunities. It’s creating options. It’s not taking it away, it’s just making it better.”

        Print Grows Trees

        August 21, 2010

        by: Kerry C. Stackpole, CAE

        In the turmoil of change, people sometimes misread what they see and hear. While the floodgates of modern media have brought us an amazing array of information, images, and ideas, it also has brought with it a shocking amount of misinformation and sensory overload. If there’s a mantra for the 21st Century, it should be, “take a closer look.” That’s one of the reasons we launched Print Grows Trees, an educational campaign that uses facts to show that print on paper actually helps to grow trees and keep our forests from being sold for development. By connecting the dots between print and the private landowners who own almost 60 percent of U.S. woodlands, Print Grows Trees challenges the widely held belief that by using less paper, trees will be saved.

        A surprising number of people believe that not printing on paper saves trees. While being a responsible user of natural resources is important, the paper and forest industry grow and harvest trees specifically for paper making. These managed forests better serve the environment through carbon sequestration and cleansing of the water aquifer. Print creates a demand for paper, which in turn creates a demand for trees and managed forests, all the while holding development or other less environmentally friendly uses of land at bay. It may seem counter-intuitive, but it’s true.

        Interestingly, a surprising number of people believe e-devices (smart phones, iPads, laptops/net-books, e-readers, and computers) have little to no impact on the environment. The fact that it’s against the law in 50 states and the District of Columbia to toss our cell phone in the trash ought to tell us something – after all, lithium batteries are hazardous waste. Unfettered access to the online world sucks up huge amounts of electricity and other resources, requiring enormous brick and mortar buildings, high-tech security systems, back-up diesel generators, air conditioning, lights, computer servers, and unfettered access to electrical supplies to sustain 24/7/365 operations. The consumption of electricity to fuel data centers is growing 24 percent a year. The power plants generating this electrical power burn mostly coal and petroleum products. Tack on the premature obsolescence of computing technology and you are looking at 300-400 million tons of non -renewable e-waste every year. “E” most certainly is not free.

        While some take newspapers, magazines, and book manufacturers to task for not quickly adopting new forms of content delivery such as e- readers, the argument that paper is used to create scarcity conveniently overlooks the fact that only 83 percent of U.S. homes have computers and only 63 percent have broadband access. In today’s marketplace, e-readers are largely out of financial reach for families and most especially, for children. Paper, in the form of books, magazines, catalogs, and newspapers, is freely available in public libraries, schools, and on newsstands at reasonable prices.

        Paper as a metaphor for scarcity seems wildly obsolete. E-devices are here to stay, but that doesn’t mean paper or print must go. If you love breathing fresh air, drinking clean water, and the green vistas of forestland, assuring a steady demand for print, paper, and trees may be the best and most beneficial idea yet. In a world bombarded by electronic images and media, many forget the value of print to our society. It contributes in economic, social, and environmental ways that have not been clearly represented to the public. Print Grows Trees concentrates on the environmental, because the misconception that if we stop using print, we’ll save trees has had a critical impact on not only the print industry, but also on the private landowners who are the keepers of America’s trees. We want people to make their communications decisions based on facts. After all, print is the renewable way a responsible world communicates.
