Converting plastics to energy
Gorski   8/27/2014 2:22:59 PM
On paper, this seems like a good idea waiting to happen. What the study doesn't say is what is involved in turning plastic into energy. Must it be sorted? How is that done. What energy inputs are required? Is there a net energy gain? If this is a feasible approach to converion of plastics into energy why hasn't somebody done something about it?

Reducing Greenhouse Gas Emissions
Greg M. Jung   8/27/2014 2:16:35 PM
Encouraging article and a great idea.  I did not realize how much energy is stored in the plastic objects that we throw away.  I am also intrigued by the opportunity to reduce greenhouse gas emissions.  While converting plastics to energy would reduce greenhouse gas emmisions from the plastics in landfills, would there be other, newer emissions generated from the resulting new conversion process?  (I'm assuming there would still be a net reduction in greenhouse gas emissions).

Good news, but slow progress

It's good to know that recycling and waste-to-energy conversion increased since the last study 3 years ago. But what's disappointing is how small the increase was and how slowly the implementation of these efforts are progressing. The technology is already available, as we've reported. Establishing an infrastructure, though, takes a lot more time.

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 millionmiles.
More bioplastic materials have entered the 3D-printable filament fray. These PLA formulations reinforced with wood or bamboo fibers will debut at the October Composites Europe show in Germany.
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.
GE Aviation not only plans to use 3D printing to mass-produce metal parts for its LEAP jet engine, but it's also developing a separate technology for 3D-printing metal parts used in its other engines.
