Plastics remain the bane of many environmentalists, but aspiring venture capitalists seem to see polymers in a different light. Two of the top four finishers in this year’s Rice University Business Plan Competition focus on plastics. The winners get star treatment in the current issue of Fortune Magazine in a section headlined “Venture”.
The first place finisher is a new pharmaceutical and number two is an Internet tool for human authentication. And at number three is a project called PK Clean from two students at the Massachusetts Institute of Technology. Their intriguing idea? Conversion of plastic waste into diesel fuel. That should stop all the trash talk about plastics.
At the fourth spot is a project called cyclewood Plastics from a student team at the University of Arkansas. These students have developed a marketing plan for a biodegradable plastic bag made from a byproduct of paper production. OK. That one sounds like a pretty well tried-and tested idea. Many companies are now selling biodegradable plastic bags from a variety or renewable feedstocks. The one edge for cyclewood is use of a waste byproduct in a technology developed at the University of Minnesota. And who knows–maybe their bags will degrade faster than the competition!
Dealing with plastic bag disposal has been the bane of the retail existence for a long time. In retail, we had seen recyclable bags in the past, but they would stick together causing significant waste. The new generation seems to have better success but do not do well in hot environments or storage.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
