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.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
