I commented yesterday on the ridiculous study commissioned by the American Christmas Tree Association that claims PVC Christmas trees are better for the environment than natural trees. A study earlier this year by a consulting firm in Canada makes the opposite conclusion. ”The results for this impact category are clear: the natural tree is better than the artificial tree considering an average life span of six years for the artificial tree. This conclusion holds true for resource depletion as well,” state researchers for Ellipsos of Montréal, Quebec. If someone kept an artificial tree for a very long time, “ideally over 20 years”, they could reduce the impacts of the artificial tree, says Ellipsos.
If you like to drive deep into the country to chop down your own tree, then you could be better off with a PVC tree, strictly from an environmental lifecycle analysis, says the study. I say, go into the country, have a great time with your kids, and chop down your own tree. Deposit the tree at a composting site when done. I didn’t do any research, but how is that worse than a PVC tree made in China?
Thanks to my colleague Don Loepp at Plastics News for citing my blog post, and pointing out the Ellipsos citation in one of the Plastics News comments.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
