Cellulose, corncob fibers and rice and peanut hulls were among the petroleum-alternative sustainable resin materials discussed during the Bio-Based Live conference for the Americas.<\/p>\n
Holli Alexander underscored the sustainability benefits of the Eastman Chemical Co.’s new Treva-brand cellulose-based engineering bioplastic.<\/p>\n
Alexander is strategic initiatives manager for Eastman global sustainability.<\/p>\n
Eastman is conducting multiple Treva field trials now under confidentiality agreements with current or potential downstream customers making rigid durable products.<\/p>\n
“Bio-based is not enough,” she said. “You need performance, and the product must work and be affordable for all.”<\/p>\n
Alexander noted manufacturing’s historic “take-make-waste” model and suggested movement toward the “repair-remake-recycle” circular economy concept of the Ellen MacArthur Foundation of Cowes, England.<\/p>\n
After discussing Treva development in 2016, Eastman launched the product at the Chinaplas trade show in May.<\/p>\n
Free of bisphenol A and phthalates, Treva grade GC6021 has a bio-based content of 42 percent and Treva grade GC6011 has 45 percent as certified under the U.S. Department of Agriculture’s BioPreferred program. Traditional petrochemicals form the remainder.<\/p>\n
Eastman sources the cellulose from suppliers certified for sustainable forest management practices.<\/p>\n
The Kingsport, Tenn.-based advanced materials and specialty additives company has legacy capabilities for compounding cellulosic plastics going back to its 1924 development of cellulose acetate films.<\/p>\n
Bio-based toys<\/p>\n
Material formulator Green Dot Bioplastics LLC of Cottonwood Falls, Kan., and toymaker BeginAgain Inc. of Fort Collins, Colo., collaborate on eco-friendly projects.<\/p>\n
Mark Remmert, CEO of Green Dot Bioplastics, and Chris Clemmer, co-founder of BeginAgain and the firm’s industrial designer, described how to develop and market bio-based toys including award-winning Eco Rigs licensed by Deere & Co., flavor-scented ice cream scoops and GreenRing teethers.<\/p>\n
\u201cI think the last century belonged to cheap hydrocarbons,\u201d Remmert said in his presentation. \u201cThe next century will usher in a vast array of biologically derived raw materials for food, fuel, fiber, plastics and chemicals.\u201d<\/p>\n
For the Eco Rigs, Green Dot developed a starch-based Terratek-brand biocomposite combining corncob fibers and Braskem SA’s ethanol-sugarcane-based I\u2019m Green-brand polyethylene. Braskem produces the PE at a plant it commissioned in 2010 in Rio Grande do Sul, Brazil.<\/p>\n
The bio-based resin carries a scent of the crops grown and harvested with the same dump trucks and front loaders that the toys depict.<\/p>\n
In 2012, BeginAgain helped Green Dot introduce its new compostable elastomeric bioplastic, Terratek Flex, to parents and children. The starch-based material was scented with essential oils of chocolate, vanilla or strawberry and used to create the scoops for an ice cream play set that smelled good enough to eat.<\/p>\n
BeginAgain also used the soft cornstarch bioresin to encircle a 3-inch loop of smooth maple wood to create the GreenRing teether.<\/p>\n
BeginAgain contracts for production with injection molders in Colorado Springs, Colo., and Spring Grove, Ill.

Totally Green compostable bottles<\/p>\n
Totally Green Bottles and Caps LLC of Red Oak, Iowa, is beginning proof-of-concept closed-loop recycling demonstrations of its compostable 100-percent plant-based water bottles, caps and labels. Six initial sites will operate during the first half of 2018.<\/p>\n
Totally Green has a partnership \u201cwith a smart group of people\u201d at Urthpact LLC in Leominster, Mass., said William Horner, Totally Green founder and CEO. The operation received an equipment loan from the Massachusetts Development Finance Agency.<\/p>\n
Demonstration sites include schools, airports and stadiums. For broader applications at a later date, Totally Green plans to talk with the trade association Green Sports Alliance of Portland, Ore., along with professional leagues and college athletic conferences.<\/p>\n
\u201cWe mean to change the looks and substance of plastic bottles,\u201d Horner said. \u201cWe are trying to turn an ugly negative into a positive.\u201d Totally Green employs 15.<\/p>\n
To ensure a secure closed loop, he prohibits sales on retail shelves and instead contracts for recycling \u201cwith industrial composters who pick up food scraps,\u201d he said. To put it mildly, he abhors the thought of Totally Green bottles entering a traditional recycling stream.<\/p>\n
The Leominster team engineered a way to mold compostable plant-based plastics after recognizing the insufficiency of traditional injection molding methods.<\/p>\n
\u201cIt took five years to get a compostable material for the caps,\u201d he said, with material from \u201cmultiple sources for the proprietary resin recipe.\u201d<\/p>\n
A shop in Switzerland made the mold. The Leominster plant produces preforms, the water bottler handles blow molding at the filling site and a contract processor makes the proprietary compostable labels.<\/p>\n
In 2003, the farmer-educator-entrepreneur started Naturally Iowa LLC, an organic dairy processor using polylactic acid containers. Horner founded Totally Green in 2012 to target the market for plant-based bottles. The materials come from corn, rice and peanut hulls and other plants.<\/p>\n
Investments in Malaysia<\/p>\n
Biotechnology firm Verdezyne Inc. of Carlsbad, Calif., is making progress in construction of a 20,000-square-foot plant on a leased site in the Bio-XCell park in Nusajaya, Malaysia. Production should begin in 2019.<\/p>\n
The development joint venture Bio-Xcell Sdn. Bhd. provided Verdezyne with a loan of approximately $75 million (250 million Malaysia ringgits).<\/p>\n
Verdezyne in partnership with conglomerate Sime Darby Bhd. of Kuala Lumpur, Malaysia, will use palm oil to produce dodecanedioic acid, a renewable bio-based chemical known as Triple DA.<\/p>\n
“We are focused on Triple DA,” said Tom Beardslee, Verdezyne vice president of research and development. “We know the initial platform.” Target markets include food, feed and animal nutrition. Verdezyne employs 68 persons.<\/p>\n
“We need regulatory approvals,” Beardslee said noting the need for further investment and downstream partnerships. “We want someone with success in the market we are entering and wanting to expand.”<\/p>\n
Method taps ‘nature’s solution’<\/p>\n
Kai Johnson explained that Method Products pbc incorporates the chemistries of 26 ingredients in making a bottle to hold Method’s laundry detergent. Johnson is San Francisco-based Method’s senior director and green chief.<\/p>\n
Johnson said Method uses “nature’s solution” \u2014 sophorolipids \u2014 in the manufacturing process at its plant on Chicago’s South Side. The surface-active glycolipid compound can be synthesized with non-pathogenic yeast for use as a bio-surfactants.<\/p>\n
On Sept. 14, privately owned consumer product firm SC Johnson & Son Inc. of Racine, Wis., said it is buying Method Products and its sister company Ecover Belgium BV of Malle, Belgium.<\/p>\n
Sustainable flexible packaging<\/p>\n
Elk Packaging of Los Angeles is producing sustainable flexible film packaging now being used for the organic pearl Heirloom Quinoa line from Alter Eco Americas Inc.<\/p>\n
Elk uses a range of materials including polylactic acid, polybutylene succinate and polyhydroxyalkanoates as it changes or modifies content in conventional flexible film packaging to adjust the barrier, print and sealability performance values.<\/p>\n
Elk has a “vision of zero-waste packaging,” said Reyna Bryan, director of strategy, and aligns with brand, material supplier and manufacturing partners including Tipa Corp.<\/p>\n
Tipa Co-Founder and CEO Daphna Nissenbaum said her firm aims to develop organic packages that can be composted. Tipa is based in Hod Hasharon, Israel, with a U.S. office in Morristown, N.J.<\/p>\n
“Tipa’s technology is inspired by an idea from nature’s packages,” she said, noting the decomposition properties of an apple or orange. “We want to treat plastic as organic waste.”<\/p>\n
London-based food producer Snact Ltd. partnered with Tipa beginning in September 2016 and uses Tipa film for packaging that can biologically decompose in a home compost heap or a food waste collection system.<\/p>\n
Innovation awards<\/p>\n
Conference organizers presented bio-based innovation awards for the Americas.<\/p>\n
Green Dot Bioplastics received the top bio-based product of the year award for its John Deere Eco-Rig project with BeginAgain.<\/p>\n
