One of Hewlett Packard’s environmental goals is use of biobased plastics. It’s a goal that goes back at least six years, and so far it’s had a rocky path. Efforts to build a printer housing from plant-based went afoul a few years ago. “The first problem we had was the polylacticacid (PLA) we used came from genetically modified crops, and that never could have been used in Europe,” comments John Frey, who chairs Hewlett Packard’s environmental strategies council. “The other problem is that they weren’t really heat stable. I took one of the pilots to a meeting in downtown Houston and then left it in my car. When I came back, the whole shell had caved in around the printer mechanism.” More recently, HP came very close to shipping a notebook with two biobased parts. The parts were withdrawn at the last moment because of other engineering concerns. Frey says HP has its eye on kenaf to see if it can add required stability as a reinforcing material.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
