I’ve been highly critical of “greenwashing” in this space where companies make environmental claims for their products that are often half-baked. I came across an effort today by Herman Miller, however, that is very impressive. Design engineers at the Michigan office furniture manufacturer have adopted cradle-to-cradle, a design protocol that advocates the elimination of waste by recycling a material or product into a new or similar product at the end of its intended life, rather than disposing of it. There are three fundamental components: 1) eliminate hazardous material chemistries, 2) design for disassembly, and 3) use recycled content to the extent possible. Some materials on the Herman Miller “hit” list are: formaldehyde-based particleboard, fiberglass, antimony oxides, PVC, some metal finishes, halogens and fluorochemicals. Wow. In some cases, Herman Miller is actively lobbying producers to make changes. The company has a great environmental glossary on its Web site.
The amount of plastic clogging the ocean continues to grow. Some startling, not-so-good news has come out recently about the roles plastic is playing in the ocean, as well as more heartening news about efforts to collect and reuse it.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
