Many of the plastics on display at the recent NPE2012 show in Orlando, Fla., were sustainable in one way or another, and their manufacturers' booths were highly visible in the show's Emerging Technology pavilions. Some of them, like BASF's Ecovio, are compostable or recyclable at the end-product stage, some are made from recycled materials, like SABIC's Xenoy iQ or Stryrolution's PCR materials, and some are constructed of bio-materials, such as Altuglas' Rnew.

Compared to other Plexiglas formulations, bio-based Rnew-maker Altuglas says it has greater melt flow and lower processing temperatures. Its properties, including impact resistance and chemical resistance, can be tailored, and it can be first extruded, then thermoformed with a high degree of detail, as shown here.

Hopefully, this film is available to be applied in a large scale application. Many large scale farm plants have been genetically engineered to specifically resist herbicides (ie Round Up Ready Corn). This allows the farmers to spray the entire field to kill weeds while retaining their cash crop. If this film allows for the farmer to reduce the amount of herbicide and geneticallly engineered seed, it would only be a net gain to consumers.
Tim, this material is specifically targeted for large-scale agricultural applications, as an alternative to poisonous sprays like Roundup and genetically modified (GM) crops. So is black petro-based plastic, but this material has even more benefits, since it can be plowed under, saving time and cost of removal, and saving the damage done if not removed.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
