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.

Beth, I also live in the country and I also see plastic litter on the roadside. In fact, I carry a trash bag, pick it up and bring it back to recycle. I can't understand littering, either: I used to go backpacking and the rule I learned is make it look like you were never there. At least if plastic trash is biodegradable it won't take an extremely long time for the plastic to break down and become harmless constituents of the ecosystem.
A green plastic films manufacturer stopped by the PackExpo booth of my company about four years ago, with some sample preformed bags. They wanted to test their bags on our equipment. We were happy to run the test right there.
The bags were incredibly stiff and "hard" compared to regular LDPE packaging material. This material sounded like cellophane when handling it (lots of LOUD crackling crunching noise). The material was also very, very fragile. It had no stretch, no give. Stress it just a bit, and it rapidly tore.
It was green (made from corn), and would degrade readily, but it wasn't very usable for packaging. There's still a lot of work to be done in the field to make a usable green material for packaging.
Cool slide show, Ann. I particularly liked seeing the BASF materials being used in food packaging applications. All you have to do is take a walk (I live out in the country and it's still a problem) and it's an eye opener to see the cups, bottles, and fast food trash littering the sides of the road. Given that it's harder to change people's behavior (although I can't understand littering, but that's a totally separate issue), it's comforting to know progress is being made on creating products that will be a bit easier on the environment.
NASA's MAVEN spacecraft has entered Mars' atmosphere, carrying instruments to help Earthlings figure out what happened to it. Launched last November, the spacecraft arrived at the red planet right on time after a journey of 442 million miles.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
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.
