One of the hot trends on college campuses right now is a higher level of environmental consciousness in cafeterias, once plagued by wasteful food fights. The Sustainable Endowments Institute says that 42 percent of the schools it surveyed have cut back on use of trays, and in some cases totally eliminated them. One college estimates it has saved 14,000 gallons of water by eliminating use of trays at just one dining hall. Details can be viewed at the College Sustainability Report Card. There has also been a drop in food waste, based on the theory that people toted more when they had a tray. There’s also a trend to use of biodegradable plates and utensils, which can be thrown in a composter with food waste. Gosh, I remember when we first started using fiberglass trays in the 1950s. They were cool. Now they’re not. I also remember when I scoffed at the idea of using composters to get rid of waste. I have one now in my backyard. But I haven’t stooped to using biodegradable plates and utensils-yet.
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.
