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.
How can automakers, aerospace contractors, and other OEMs get new metal alloys that are stronger, harder, and can survive ever higher temperatures? One way is to redesign their crystalline structures at the nanoscale and microscale.
Although a lot of the excitement about 3D printing and additive manufacturing surrounds its ability to make end-products and functional prototypes, some often ignored applications are the big improvements that can come by using it for tooling, jigs, and fixtures.
