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.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
