Many designers are looking to a very old
wood-based plastic to achieve a new look that has green values.
One example is a clear protective case
for the Apple iPhone 3G that showcases the device's iconic design. "We wanted a
crystal-clear material with window-like clarity," says Jedd Komlos, lead
industrial designer for Ventev Innovations. The material is called Naturacell,
a durable plastic developed by Rotuba Extruders Ltd
of Linden, NJ,
that blends a natural-based softener with Eastman cellulosics derived from the
pulp of softwood trees.
This plastic has deep roots. Eastman
Kodak founded the Tennessee Eastman Co. in 1920 to manufacture wood alcohol for
film base. In 1932, Tennessee Eastman began production of its first plastic -
Tenite acetate. It was the first thermoplastic and found widespread use in
Craftsman tool handles, toys, sunglass frames, toothbrush handles and
Cellulosic plastics, which are composed
of 40 to 45 percent wood pulp, have a distinct feel and scent. Tenite has been
replaced in some applications in recent years because of its high price
relative to commodity plastics such as polystyrene.
But other designers are latching on to
the sustainability angle. "All of our wood pulp comes from sustainably managed
forests," says Gaylon White, director of design programs at Eastman Chemical,
which was spun off from Eastman Kodak in 1993. "For every two trees that are
harvested, three are planted." Most of the trees come from Southern softwood
forests, and all come from the U.S.
The iPhone case from Ventev accelerates
the sustainable angle by using packaging made from fully recycled paperboard.
But designer Komlos also likes the clarity of Tenite and the surface finish.
"It's very smooth and soft," he says. "If you run your fingernails across the
surface, they glide as smooth as ice."
One big payoff could be interior touch
points in high-end luxury cars, says White. So far, however, there have been no
automotive interior applications.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
