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.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
The latest crop of coating and sealant materials and devices has impressive credentials. Many are designed for tough environments with broad operating temperature ranges, and they often cure faster, require fewer process steps, and produce less waste.
A new program has been proposed for testing and certify 3D printing filaments for emissions safety. To engineers who've used 3D printers at home this is a no-brainer. It's from a consumer on Kickstarter, and targets use in homes and schools.
For the last 50 years, the Metal Powder Industries Federation (MPIF) has sponsored an awards competition for creative solutions to designing and fabricating near-net-shape parts using powder metal (PM) technologies. Here are the seven Grand Prize winners of the 2015 contest.
Graphene 3D Lab has added graphene to 3DP PLA filament to strengthen the material and add conductivity to prints made with it. The material can be used to 3D print conductive traces embedded in 3D-printed parts for electronics, as well as capacitive touch sensors.
