I have never been a big fan of biodegradable plastics, primarily because of what I consider bogus marketing. There is no environmental advantage to biodegradable packaging unless you’re the type who throws wrappers out of your car window. Properly run landfills are anaerobic. That is, they have no air or water because material degradation is an environmental problem. Chemicals leach into aquifers or form methane gases that contribute to global warming.
A company called Green Toys is now launching toys made from biodegradable plastic. Their pitch is simple and fair: plastics made from corn or potatoes use less energy to produce than plastics made from oil. There is no documentation of that claim on their Web site, however, and there should be because fuel made from corn (ethanol) may consume more petroleum than it saves. Furthermore, Green Toys use biodegradable colorants supplied by PolyOne Corp. That sounds like a real winner.
Green Toys also uses packaging made from recycled materials. Again another real score.
A composite based on a high-performance PEEK-like resin we told you about two years ago when it was still in R&D has now been licensed by the US Naval Research Laboratory (NRL) for commercial manufacturing.
Microsoft, HP, Dassault, and other industry heavyweights in 3D printing have launched a new 3DP file format, 3MF. The consortium says the spec will more fully describe a 3D model and will be interoperable with multiple applications, platforms, services, and printers.
NASA's been working on several different ongoing projects for 3D-printed rocket engine components in metals and now it's reached another first in aerospace 3D printing: a full-scale, 3D-printed rocket engine component made of copper.
