Plastics made from sustainable resources, or plants, are at a tipping point, according to several speakers at special session at the annual technical conference (Antec) of the Society of Plastics Engineers in Milwaukee, WI. According to one research study cited, 40 percent of bioplastics will be used in durable applications in 2011, compared to just 2 per cent today. In the United States, in particular, plastics made from crops, usually corn, are mostly targeted for disposable packaging. As I’ve blogged before, that’s a joke since there are virtually no composting facilities that could handle the biodegradable packaging. The argument works OK for plastic bags that are thrown in the ocean or beside highways. But that’s hardly a reason to develop a new industry. Speakers at the SPE Antec, however, made the point that the argument is shifting from a solid waste viewpoint to a carbon footprint orientation. As a result, some experts feel demand will grow for “bioplastics” because of its potentially favorable position in the global warming debate. Japan has a law requiring greater use of bioplastics over the years, and Toyota among others has embraced the goals. The case is gaining a little strength as oil prices soar. It’s still a tough row to hoe, however. One reason is that bioplastics lack adequate mechanical properties for durable applications, such as cars. Toyota is blending bioplastic with oil-based plastic to boost properties. The other issue is that bioplastic will be significantly more expensive than oil-based plastic, even with sky-high oil prices. Efforts in the past to develop alternates have always collapsed when oil prices dropped. The other big obstacle is the feedstock problem. Use of corn in the United States has hiked food prices. At the Antec, a few experts argued that the real solution will be a switch to biomass that has no food value.
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
