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.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
