That all plastics are not recyclable really irks me — things like those clear plastic tubs that spinach comes in. I put them in the recycling bin and the guy in the recycling truck tosses it in the trash along with those little plastics bottles holding hotel shampoo. They don't have the recycling number on the bottom so just a little more petrochemical trash gets wasted. Our recycling folks and some stores take back 1s, 2s, 3s and some 4s, but 5s, 6s and 7s get tossed.
Of course, plastics is an alphabet soup of acronyms - PETE, HPDE, V, LPDE,PP, PS and 7 is "other." I am big believer in recycling and feel strongly all plastics containers should be not be made unless there are made from recylable material. I'm sure the bottle and resin makers would scream bloody murder at the prospect of a federal recycling mandate. For instance, New Hampshire - the Live Free of Die state - considers a bottle deposit an imposition of its inalienable rights. In Massachusetts, we've had it for decades. But it's not the nineties anymore.
Maybe our plastics editor and expert Doug Smock who authors the Engineering Plastics blog can explain why not all plastic is recycleable.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
